WAUKESHA F-817-G SERIES
SAFETY PRECAUTIONS
For details on safety rules and regulations in the
United States, contact your local Occupational Safety
and Health Administration (OSHA).
These safety precautions are published for your
information. The Waukesha Engine Division, Dresser
Industries, Inc., does not, by the publication of these
precautions, imply or in any way represent that these
published precautions are the sum of all dangers
present near industrial engines. If you are operating
industrial engines, it is your responsibility to ensure
that such operation is in full accordance with all
applicable safety requirements and codes. All
requirements of the United States Federal
Occupational Safety and Health Administration Act
must be met when Waukesha engines are operated
in areas that are under the jurisdiction of that United
States department. Engines operated in countries
other than the United States of America must be
installed, operated and serviced in accordance and
compliance with any and all safety requirements of
that country which may be applicable.
BODILY PROTECTION
Wear OSHA approved bodily, sight, hearing and
respiratory system protection. Never wear loose
clothing, jewelry or long hair around an engine.
EXHAUST GASES
Engine exhaust products are toxic and may cause
injury or death if inhaled. All engine installations
must have an exhaust discharge pipe so that exhaust
gases are delivered into the outside air. A closed
building or shelter must be adequately vented to
provide a steady supply of fresh air.
ENGINE FUELS
Engine fuels are highly combustible and may ignite or
explode. Fuels must be conducted to the engine with
proper piping, free from leaks, and designed to resist
breakage from vibration. When filling fuel tanks,
never smoke or use open flame in the immediate
area. Fuel tanks should be grounded to prevent
buildup of static electricity. If a gas engine has been
cranked excessively without starting, shut off the gas
fuel supply and ignition. Then crank the engine to
purge the cylinders and exhaust system of
accumulated, unburned gas. If you fail to do this, a
spark plug could ignite the gas and cause an
explosion.
POSITIVE FUEL SHUT-OFF
(natural gas, liquified petroleum gas, etc.) should
haYe another positive shut-off valve, preferably
automatic, other than those in the carburetor or gas
. pressure regulation equipment. It is the final
responsibilityof the engine ownerto ensure that the
installation is free from fuel or exhaust leakage, and
such installation meets all applicable codes.
GAS USED TO ENERGIZE STARTERS
Gas used to energize starters must be discharged
away from the engine into a harmless area. There is
also a possibility of leakage around the starter output
shaft during cranking. Ignition connections and
electrical equipment on engines exposed to a
potentially explosive atmosphere should be equipped
to eliminate spark hazard. It is the responsibility of
the engine owner to specify or provide such
connections and equipment.
SAFETY GUARDS
Engines must be provided with guards to protect
persons or structures from rotating or heated parts. It
is the responsibility of the engine owner to specify or
provide such protection.
CRANKCASE ANTI-EXPLOSION VALVES
These valves must be kept in proper working
condition to relieve crankcase pressure.
IGNITION SYSTEMS
Ignition systems can cause electrical shocks. Avoid
contacting ignition units and wiring.
COOLING SYSTEM PRESSURE CAPS AND
CONNECTIONS
Do not remove the pressure caps while the engine is
operating or while coolant is hot. The cooling system
is under pressure and severe burns could result from
the hot coolant spewing out when the cap is
removed. Wait until the engine and coolant have
cooled down before removing the radiator or surge
tank caps. Always replace weak hoses, lines, and
fittings.
FUEL INJECTORS
Never allow an injector to spray against the skin. The
fuel oil will penetrate the skin and may cause serious
infection and injury.
GENERATOR SETS
Some means of positive fuel shut-off should be
provided for emergency use. Pressurized fuels The voltage produced by generator sets is dangerous.
Roghan Rd Hardfill Leachate Pump Tip Engine OM Manual
Q-Pulse Id TMS652
Active 29/01/2014
Page 6 of 140

WAUKESHA F-817-G SERIES
Severe, possibly fatal, shock may result from contact.
Make sure the generator set is grounded before
operation. Be extremely careful when the unit or
surrounding area is damp or wet.
When servicing any part of the electrical system or
making any connections, make sure main power
switch is OFF. Clean or service generator set only
when engine is shut down.
In case of an accident from electrical shock, shut
down the generator set at once. If it cannot be shut
down, free the victim from the live conductor. Avoid
direct contact with the victim. Use a dry board, dry
rope, or any nonconducting implement to free the
victim. If the victim is unconscious, apply artificial
respiration and get medical help.
Do not operate the generator set with the ammeter
circuit open. Voltage, dangerous to both equipment
and personnel, can be generated in an open
secondary circuit of a current transformer.
If the generator set is stopped by operation of safety
devices, do not attempt to operate it until the cause
has been eliminated.
Whenthe generator set is shut downafter operation,
disconnect all line switches toall external power load
and parallel circuits.
ENGINE AND EQUIPMENT, REPAIR AND SERVICE.
Always stop the engine before cleaning, servicing, or
repairing the engine or driven equipment. Place all
controls in OFF position to prevent accidental
restarting. If possible, lock all controls in the OFF
position and take the key. Put a sign on the
instrument panel warning that the engine is being
serviced. Before restarting, make sure that all tools
and other material are removed from the engine and
equipment.
Proper service and repair is important to the safe,
reliable operation of engines and related equipment.
The procedures recommended by Waukesha in this
manual are effective methods for performing service
and repair operations. Some of these procedures
require the use of specially designed tools. The
special tools should be used when and as
recommended. Anyone who uses a service, repair, or
installation procedure not recommended by
Waukesha must first satisfy themselves thoroughly
that their safety will not be jeopardized by the service
methods they select.
HOUSEKEEPING
Good housekeeping results in a clean, safe work
area. An orderly work area with clean walkways and
neatly arranged tools and equipment is a majorfactor
in accident prevention.
ENGINE FAN BLADES
1. Do not operate the engine with a fan which has
been bent, multilated, modified or in any way
damaged.
2. Do not operate the engine if the fan contacts or
strikes any engine accessory or the radiator
shroud or core.
3. Do not rebalance the fan. Contact the fan
supplier if rebalancing is required.
4. Ensure that all bolts attaching the fan are
securely installed to a torque specified by the
engine or vehicle manufacturer.
5. Install the fan so the word "front" stamped on
the fan faces the radiator.
6. Perform all required maintenance on the
subassembly to which the fan is attached
(waterpump, fan drive, etc.) (See operator/
service manual.)
7. Do not modify or substitute any parts of the
engine without the approval of the Waukesha
Engine Division Service Department. Take
special care not to make modifications which
will increase the operating speed of the fan.
8. Install the fan only if the engine has been
approved for fan installation. Likewise, install a
subassembly to which the fan is attached
(waterpump, fan drive, etc.), only if approved or
specified for use on the engine.
9. If the fan or fan drive contains any plastic or
rubber component, have the fan and drive
inspected by a qualified mechanic after
operation at or exposure to excessively high
temperatures [above 250° F. (120° C.) air
temperature].
10. Replace the fan if indications of excessive
corrosion or erosion appear in the fan.
11. For reversible or adjustable pitch fans, make
sure the blades are correctly locked in the
proper position prior to operation. Also, inspect
the fan prior to operation to ensure that ice and
dirt have not accumulated on the fan to cause
potential unbalance of the fan.

WAUKESHA F-817-G SERIES
12. Be sure all fans, fan drives and belts are
properly shielded.
TURBOCHARGERS
Turbochargers are specifically designed for each
application. Nozzle rings must not be changed
without consulting the engine manufacturer since
they limit turbocharger rpm. Excessive rpm may
result.in turbocharger failure with resultantpersonal
safety hazards. Turbochargers operate at high
temperatures. Therefore,. all flammable material
must be kept away from them. Engines must be shut
down and at room temperature before working on
turbochargers or burns will result. Keep all foreign
material away from turbocharger openings.
ENGINE STORAGE CHEMICALS
Waukesha Preservative Oil contains a petroleum
distilate which is harmful or fatal if swallowed. Avoid
contact with skin. Vapor is harmful and causes
irritation of eyes, nose, throat and skin. Use only with
adequate ventilation. Avoid prolonged or repeated
breathing of vapor. Avoid contact with skin, eyes, and
clothing. Do not take internally. Keep container.
closed and away from heat. Always read and observe
the "CAUTION- labels on the containers. Do not
destroy the labels on the containers.
Generally, heating of preservative compounds is
confined to 200° F. (93° C.) or less. These
temperatures are easily reached by placing the
preservative container in heated water. If this is
done, the container must be vented or opened to
reduce the danger of explosion. Direct heating
presents a dangerous and unnecessary fire hazard.
FIRE PROTECTION
Locate fire extinguishers so that they are easily
accessible if a fire starts. Carefully maintain records
of extinguisher inspection and recharging to ensure
the fire extinguishing capabilities when required.
Consult your fire extinguisher supplier or insurance
engineer for recommendations on the type, size, and
quantity of lire extinguishers required. Select and
post alternate routes of escape from any engine
installation. Design installation to meet all applicable
fire codes.
CLEANING SOLVENTS
Use approved cleaning solvents in a well ventilated
area. Avoid breathing fumes; some vapors can be
fatal. Keep away from Open flames or sparks. Do not
use gasoline or paint thinners or other highly volatile
fluids for cleaning. Always read and observe the.
"CAUTION" labels On containers. Do not destroy the
labels on the containers. Cleaning solvents can
cause various types of skin irritations.
WELDING EQUIPMENT
Welding gas cylinders can explode if damaged.
Cylinders must be stored in accordance with
manufacturer's specifications and applicable safety
requirements.-
When using acetylene, check valves should be
installed between the regulators and hoses to
prevent flashback into the regulators and supply
tanks. Flashback could cause the regulators and
supply tanks to explode.
Oily and greasy materials must be kept away from
oxygen valves, hoses, etc. Oxygen may combine with
such materials and an explosive reaction could
result.
Always wear protective eye shields when welding,
cutting or watching a welding operation. Protective
clothing and face shields must be worn. Do not weld
or cut near combustible materials.
GROUNDING PRECAUTIONS WHEN WELDING
When using an electric welder on an engine, clip the
ground lead as close to the welding site as possible.
Putting the ground lead too far from the welding site
may result in arcing across the main bearings, and
fusing them to the crankshaft.
ELECTRIC POWER TOOLS
Be certain the electric tool is properly grounded.
Wear proper eye protection. Do not work in wet or
damp conditions. Be sure the tool is in good condition
and safety guards are in position. An electric trouble
light must also be grounded. Do not carry electric
power tools by the cord. Do not yank the cord when
removing from an outlet; instead grasp the plug to
remove it from an outlet.
LEAD ACID BATTERIES
Always disconnect the battery ground connection
from batteries before performing any work on the
engine or equipment. This will prevent sparks or
burns when accidently shorting an electrical
connection.
Never expose batteries to .open flame or electric
spark. Battery action generates a flammable,
explosive gas. Don't allow battery fluid to contact
skin, eyes, fabrics, or painted surfaces. Battery fluid
is a sulphuric acid solution which could cause
Roghan Rd Hardfill Leachate Pump Tip Engine OM Manual
Q-Pulse Id TMS652
Active 29/01/2014
Page 8 of 140

WAUKESHA F-817-G SERIES
serious personal injury or property damage. Wear
eye protection when working with batteries.
Precautions When Using Booster
Batteries and Cables
Do not attempt to jump start an engine having a
frozen battery. The battery may rupture or explode.
Before starting, examine all fill ventson the battery. If
ice can be seen, or if the electrolyte fluid cannot be
seen, do not attempt to start with jumper cables.
Batteries should be treated carefully when using
jumper cables. The following procedures assist in
reducing sparks and explosion hazards always
present in both batteries when connecting charged
batteries to discharged batteries:
Turn off all electrical loads. Remove vent caps and lay
a damp cloth over open vent wells of each battery.
The charged booster battery or batteries must have
the same voltage capacity as the discharged battery
or batteries.
The positive post is identified by a "+", pos. and red
color and is larger in diameter than the negative post.
The negative post is identified by a "-", neg. and
gray color.
Negative Grounded Battery or Batteries
First, connect one jumper cable from the positive post
on the charged batteryor batteries to the positive post
on the discharged battery or batteries. If more than
one battery is connected in "series" or "series
parallel", connect the jumper cable to the positive
post that has the cable leading to the starting motor.
Second, connect the other jumper cable from the
negative post on the charged battery or batteries to a
good ground on the engine.
When removing jumper cables, always disconnect
the ground jumper cable from the engine before
disconnecting the other jumper cable.
Positive Grounded Battery or Batteries
This is the same procedure as for negative grounded
battery or batteries, except the negative post will
have the cable leading to the starting motor and the
positive post will be grounded.
COMPRESSED AIR
Compressed air or gases should never be used to
clean clothing or the body. Compressed air can pierce
the skin and cause severe and very painful injury.
Never use your hand to check air, gas, or liquid flow
rates. Do not engage in "horseplay- with air, gas, or
liquid hoses. Observe all applicable regulations as
related to compressed gases.
SODIUM FILLED VALVES
When handling sodium filled valves always wear
approved safety goggles, a hat or cap, long sleeves,
and gloves. If refacing of sodium filled valves is
required, do not exert undue force at the grinding
wheel as this could crack the hollow valve stem and
allow the sodium to escape.
Do not handle broken sodium filled valves with bare
hands. Sodium or sodium residue can cause severe
burns. Sodium burns are of the same nature as
caustic burns. Wash burns with large volumes of cold
water, then neutralize with vinegar. The affected
parts should then be treated as a burn and medical
attention sought.
If a broken valve should ignite, smother the flames in
dry soda ash or dry sand. Water, carbon dioxide in any
form, or carbon tetrachloride should never be used on
sodium fires since these materials react violently
with hot sodium. The smoke and fumes are irritating;
adequate ventilation should be provided and
inhalation or contact with the smoke and fumes
avoided.
Broken sodium filled valves may be stored prior to
disposal in moisture free clean oil or kerosene.
Unserviceable sodium filled valves must be disposed
of in accordance with local, state and/or federal
regulations as applicable.
INTOXICANTS AND NARCOTICS
Workers under the influence of intoxicants and/or
narcotics are unsafe workers and are a hazard to
themselves and other employees.
SAFETY PRACTICES FOR HANDLING ACIDS.
Throughout this manual, acid cleaning procedures
are recommended for certain castings or pieces of
equipment.
WARNING
Always add the acid to the water -never add water
to acid when mixing solution.
1. Avoid contact with skin, clothing, and eyes.
2. Descaling operations should be performed
away from all fire, sparks or other ignition
sources.

WAUKESHA F-817-G SERIES
3. Keep acids off of concrete floors, as it attacks
lime in the concrete. If solution does get on
concrete surfaces, apply an alkaline solution to
neutralize.
4. Acids can react with metals to form various
gases. Generally, acid solutions on lime scale
and rust. result in the formation of harmless
carbon dioxide. However, when acids contact
aluminum, zinc, cadmium, tin, sulfides, arsenic
and cyanides, poisonous and explosive gases
may be generated. When descaling is being
done in closed equipment, install proper
ventilation to carry the gases away. When an
open tank or crock is used, gases should be
diluted by adequate air flow above the open
tank.
5. Always fill closed vessels from bottom up.
6. Be sure that there are no leaks in the vessel
being descaled which will permit solution to
leak into opposite side of equipment. Good
practice is to fill the opposite side of the
equipment being descaled with water to a level
higher than the acid solution.
7. Use an acid-proof pump, or an inexpensive,
expendable one.
8. When mixing with water, pour acid into the
water, do not pour water in concentrated acid.
9. Do not agitate acid solutions with air.
10. Applications of acid should be followed by
thorough rinsing, then neutralizing with an
alkaline solution to remove all acidic residue, to
prevent further action.
11. Store acid solutions in either an acid-proof
wooden or synthetic rubber lined steel
container should be used.
12. Check steel equipment to be treated with acid
solution for copper or brass fittings or fusible*
metal plugs. If possible, dissimilar metals
should be removed prior to descaling to prevent
electrolytic action which might interfere with
the inhibiting action of acid solution. DO not use
acid to descale equipment constructed of
aluminum.

WAUKESHA F-817-G SERIES DESCRIPTION
DESCRIPTION
GENERAL
Where variations exist among engines in a
given series, mention will usually be made in the
text, and detailed information may be obtained by
writing the Service Department, Waukesha En-
gine Division. Always include the engine serial
number when writing. In most cases no attempt
has been made to retrace the variations in de-
sign over years past.
F-817-G engines are produced in a commer-
cial and industrialversion. The main differences
involve operational speeds and the crankshaft
vibration dampner. Also, there are a number of
variations in ignition, manifolding, flywheels,
fans, and so on, possible within the framework
of a given series and type. For this reason, the
description of the parts must be somewhat gen-
eralized. All models may be converted to oper-
ate on either gasoline or gaseous fuels. Theyare
not available for kerosene operation.
When rebuilding or servicing an engine, it is
suggested that the latest changes and clearances
be incorporated. Tabular data printed here re-
presents the latest recommendations at time of
printing. Separate Parts Manuals, which facil-
itate ordering of replacement parts and repair
kits, are also available.
For purposes of discussion, or correspond-
ence, the following reference points have been
established.
CYLINDER NUMBERING - Cylinders are
numbered consecutively from one to six,
starting from the crankshaft pulley end of
the engine.
FRONT and REAR - Reference to such lo-
cations on the engine shall be interpreted
as meaning from the crankshaft pulley (front)
and flywheel (rear) ends.
RIGHT and LEFT - Shall be interpreted as
meaning from the right and left of a viewer
standing at and facing the rear (flywheel)
end of the engine.
ROTATION - Standard rotation is counter-
clockwise standing at and facing the rear
(flywheel) end of the engine.
Since many of the parts described contain
complex oil or water passages, no mention has
been made of these openings in most cases.

Lubrication and cooling are discussed under
separate headings later in the Description Sec-
tion.
CRANKCASE
The crankcase of the model F-817-G is a
single high-grade iron casting incorporating
seven heavily ribbed main bearing supports and
locations for the six wet-type cylinder sleeves.
Cooling water passages are formed between the
side walls of the crankcase and the cylinder
sleeves. Thus, the sleeves are always in direct
contact with the coolant for their full length.
Since the cylinder sleeves are of the re-
movable type, it is necessary to provide a seal
at both ends. At the upper end this is done
by the head gasket which seals the accurately
finished mating surfaces at the joint between
the sleeve flange and the crankcase deck recess.
Two rubber seal rings are used at the lower
end of the sleeve. Current engines utilize one
rubber seal ring and one Teflon seal ring.
The crankcase has four accurately aligned
locations for the camshaftbushings. Thesebush-
ings, located on the left side of the engine,
support the camshaft at the front and rear, and
at two intermediate points, all of which are line
bored (precision service camshaft bushings are
available) and supplied with oil under pressure.
Immediately above the camshaft are 12 cam-
follower guides cast as integral parts of the
crankcase. These guides may be rebushed as a
service measure, providing machine shop facil-
ities are available. Drilled holes from the tappet
compartment meter oil to each tappet and cam
lobe.
The forward end of the crankcase provides
a housing for the crankshaft-drive gear, and
the cam gear, magneto-drive gear, and idler
gear. The front end of this housing is closed by
a gear cover supporting the crankshaft oil re-
tainer and camshaft and idler thrust-button
plates. A line-bored idler bushing is pressed
into the front of the case. A pre-fitted, pre-
cision-type replacement is available for ser-
vice use.
At the rear end of the crankcase is a mount-
ing surface for a flywheel housing and a retainer
for the spring-loaded rear oil seal. To en-
sure accurate mounting of the clutch or other

surface of the engine is held to very close
tolerances.
Inspection panels, located on the left side
of the crankcase, permit cleaning if required.
A longitudinal rifle-drilled passageextending
along the left side of the crankcase forms the
main pressure-oil header. Threaded plugs
spaced along this rib indicate the intersection
points of oil leads to the main bearings. Re-
moval of these plugs permits cleaning of the
oil passages after crankshaft and main bearings
have been removed for inspection.
Faced mounting bosses and connections are
provided at various points on the crankcase
exterior for mounting accessories, lines, and
other equipment that may be selected by the
engine operator.

CYLINDER HEADS
The cast-iron cylinder heads used on this
engine series are available in a number of
variants depending upon the purpose and fuel
for which the particular engine is designed. It
is usually necessary to change both heads on
a given engine when an older head is replaced
by a new one of supersedingpartnumber.
Also, promiscuous interchange of heads with
conflicting part numbers between engines of dif-
ferent variants can seriously impair perform-
ance and result in costly damage.
Do not attempt to judge two heads as being
alike merely because they appear to be so.
Differences in valve insert and guide metals,
port ratios, cooling passages invisible to the
eye, valve spacings, and so on are not readily
apparent. Heads of different part numbershould
be used only after consulting the Service De-
partment, Waukesha Engine Division.
