General Overhaul Information
Tools and Equipment
The following tools and equipment are needed to overhaul a pump:
1. Usual automotive mechanic's hand tools.
2. An arbor press for assembling or disassembling components.
3. An engine lathe for turning impeller hubs.
4. A suitable hoist and slings.
5. Torque capability up to 325 lb-ft.
While no special tools and equipment are required, a few special items are
illustrated or described so the mechanic can make them or they are available
from the apparatus manufacturer or the Waterous Company. These special
items are not absolutely necessary, but they will make the mechanic's work
much easier.
Preliminary Testing
Before disassembling a pump, test it thoroughly, if possible, and record the
results. A comparison of this test with periodic tests recommended in form
F-1031, Section 1000 can often reveal specific pump troubles. Excessive
speed, for instance, indicates that impellers and/or wear rings are probably
worn.
Cleaning
The continued satisfactory operation of a pump depends to a great extent
upon the cleanliness of its internal parts. Sand, dirt or other abrasive material
will wear bearings, gears and related parts. Before disassembling a pump for
repairs, be sure to clean its exterior. Make sure the working space, benches
and tools are clean. Use only clean, lint-free cloths to wipe off components.
Before reassembling a pump or its components, be sure to clean them thor
oughly.
Pump Bodies and Impellers
Flush out these components and related parts with clean water. Use a stiff
brush to remove loose scale, caked sediment, etc. Be sure to remove all
traces of old gaskets. Examine pump bodies, covers, adapters and fittings for
cracks, severe corrosion or other damage. Almost all damage to these parts
results from improper use or maintenance, or from freezing. Replace defective
parts.
Bearings, Gaskets, Seals and O-rings
Parts of this nature are frequently damaged during removal or disassembly. In
addition, they sometimes deteriorate or lose their effectiveness because of
age or misuse. Replacing these parts whenever overhauling a pump is a good
policy.
Impeller Shafts
Examine shaft for severe scratches, grooves or corrosion - especially under
packing or mechanical seals. If scratches are not severe, and are not under
packing and seals, clean them with a fine-cut file. Grooves are usually per
missible if they are not sharp or too deep. Even slight longitudinal scratches
will cause leaks and should be removed.
Installing Ball Bearings
Most Waterous pumps are designed so that ball bearings fit tightly on their
shafts and have relatively loose fits in the bearing housings. When mounting
these bearings on shafts, always apply force to the inner races. When bear
ings have a tight fit in the housings, and a heavy force is necessary to install
them, be sure to apply force only to the outer bearing races. For either type of
fit, applying force to the wrong bearing race may damage the balls and race.
Transmission Case Gaskets
To provide added sealing for gaskets between transmission halves, coat both
sides of these gaskets with a suitable sealant. A compound such as Permatex
Super 300 is recommended for this application. Be sure all traces of previous
gaskets and sealant are removed before installing new gaskets.

Disassembly
Remove Pump From Vehicle
1. Drain fluid from transmission.
2. Disconnect propeller or drive shafts to pump transmission.
3. Disconnect pump intake and discharge piping.
4. Disconnect cooling and drain lines, electrical wiring and similar
equipment from pump and accessories.

Intake Adapter, Impeller & Mechanical Seal Removal
1. Remove the three (3) screws that attach the mounting bracket to the intake adapter and
volute body.
2. Remove hex hd screws attaching the intake adapter to the volute body. Remove intake
adapter from the volute body and remove the O-ring from the groove in the intake
adapter.
3. Remove cotter pin, impeller nut and impeller washer.
4. Remove impeller from impeller shaft. Tapping the impeller lightly with a soft hammer
may be necessary to free it from the impeller shaft so it can be removed. There are
3/8-16 UNC tapped holes in the impeller to allow use of a puller if necessary.
5. Remove square key from the impeller shaft.
6. Remove spring from the mechanical seal.
7. Apply a light coating of oil to the portion of the impeller shaft the mechanical seal is on.
Grasp the seal by hand and try to remove it with a combined pulling and twisting motion.
If it is stuck to the shaft and will not come off, it will come off when the impeller shaft and
transmission are separated from the volute body.
8. Stand the pump in a vertical position, the face of the volute body up.
9. Remove nuts fastening the transmission to the volute body. Tap the volute body lightly
with a soft hammer to free it from the transmission.
10. With a hoist, lift the volute body. The impeller shaft will probably adhere to the bellows
of the mechanical seal and it will be necessary to jiggle the volute body as it is being
removed. If the transmission lifts with the volute body, tap on the transmission with a
soft hammer.

Inspection and Repair
Impeller and Wear Rings
Check wear rings and impeller hubs for deep grooves or scratches. Spirol
grooves or grooves parallel to the impeller shaft increase leakage. Inspect
for excessive wear ring clearance. Diametric clearances in excess of .027
inches may warrant wear ring replacement. Original factory clearance is .019
to .023 diametrically. The diametric clearance should be determined by
averaging the results of four measurements taken at 90 degree increments
as follows:
Clean and remove small burrs or other protrusions from the wear ring inner
diameters and the impeller hub O.D. and I.D. Position each wear ring on the
impeller hub on which it was used. Hold the wear ring firmly against one side
of the hub and measure total clearance on the opposite side, using a feeler
gauge. Do not bottom the wear ring against the bottom of the groove in the
impeller.
Impeller hub to wear ring clearance is restored by turning impeller hubs to
sizes noted in table and by installing matching undersize wear rings. See
table.
Ball Bearings
When cleaning bearings, bearing manufacturers recommend placing them in
a basket and suspending the basket in a container of solvent, preferably
overnight. Avoid rotating the bearings before solid particles are removed, to
prevent damaging races and balls.
After cleaning, spin them immediately in light oil and check each one as
described below:
1. Examine bearing for rusted or pitted balls, races or cages.
2. Check cage and races for cracks or other damage. Examine balls
and races for brinelling, abrasion and serious discoloration. If in
doubt about condition of bearing, replace it.
3. Rotate bearing slowly, and check for roughness or excessive inter
nal looseness. If a rough spot is found, it may be dirt caked on a race.
Try cleaning it again. If endplay is doubtful, compare it with a new
bearing. If the bearings are not to be installed right away, wrap them
in clean, oil proof paper.

Inspection and Repair (Continued)
Impeller Shaft
Examine shaft for signs of severe scratches, grooves or corrosion, especially
under the oil seal or mechanical seals. If scratches are not severe, and are
not under seals, they can be ignored. Check for cracks, pitting, twisted
splines or damaged keyway.
Installing Oil Seals
Before installing an oil seal in a housing, be sure that the seal, shaft and
housing are clean.
Scratches in the area of the bellows of the mechanical seal can possibly be
removed by spinning the shaft in a lathe and polishing with a fine emery
cloth. The journal for the oil seal may be similarly cleaned, however, spiral
type polishing may lead to oil leaks.
Apply force to the outer edge of the seal and press in evenly.
Oil Seal Sleeve
Check for wear and scratches where the seal contacts the sleeve. The
journal may be polished with a fine emery cloth, however; any polishing that
leaves a spiral pattern may lead to an oil leak. If a groove has been worn in
the sleeve, it can be reused by turning it end for end.
If questionable, replace the sleeve or fit with a thin replacement sleeve. This
replacement sleeve allows use of the same size oil seal. This type of repair
sleeve is available through most sources of oil seals.
Volute Body and Intake Adapter
Examine for cracks, severe corrosion or other damage. Almost all damage to
these parts results from improper use or maintenance, or from freezing.
Replace defective parts.
Clean out drainage hole in volute body, located between the seat for the
throttle bushing and oil seal.
Throttle Bushing
Note: The bushing serves as a restriction to fluid leakage if the mechanical
seal fails.
Examine the bore in the bushing for wear due to contact with the shaft. The
size of the bore is 2.760/2.762.

1. Before installing oil seal in the seal housing, coat the
seal outer diameter evenly with sealant (Loctite Ultra
Blue RTV Silicon Sealant). Be sure that the seal, shaft
and seal housing are clean. Always install a seal with
the seal lip facing in. Apply force to the outer edge of the
seal and press in evenly.
NOTE: The pump must be attached to the transmission
before the impeller shaft can be shimmed.
NOTE: The shafts were factory shimmed to limit the ax
ial float to 0.005 - 0.010. If any of the drive line parts have
been changed, it may be necessary to change the total
thickness of shims. Perform the following:
2. Hold the bearing cover or oil seal housing in posi
tion against the transmission case without an O-
ring and measure the gap between the face of the
cover/housing and transmission case with a feeler
gage in several places. This gap thickness plus
.005" is the minimum amount of shims to select.
3. Remove bearing cover or oil seal housing and
install a new O-ring. Reinstall with shims between
the face of the cover/housing and the transmission
case. Install and tighten screws.
4. Check to assure that axial float exists either with
an indicator or by feel. If in doubt, add an additional
.005" shim. No harm will result from a small
amount of additional axial float, but bearing life will
be shortened if bearings are excessively pre
loaded.
NOTE: The shims are color coded for thick
ness as follows:

1. Temporarily install the impeller and rotate the impeller shaft. The impeller
should rotate without contact with the wear ring in the volute body. Remove
the impeller.
2. Slip the throttle bushing over the end of the impeller shaft and down onto the
bore in the volute body. Tap into position until it seats against the shoulder in
the body.
NOTICE
The mechanical seal primary and stationary rings are made of brittle material.
The material can be cracked or chipped. Extra care must be taken when han
dling these rings.
Note: If Waterous Mechanical Seal Lubricant part no. 52608 is not available, P80
rubber lubricant, straight dish soap or glycerin may be substituted.
3. Apply a light coating of seal lubricant to the O-ring in the stationary seal ring of the
mechanical seal.
Note: To protect the rubber bellows of the mechanical seal, place a piece of
masking tape over the keyway on the impeller shaft, making sure that the tape is
able to be removed after bellows has passed over the keyway.
4. Slip the seal ring over the end of the impeller shaft, with the finish lapped face of
the seal ring facing up (the opposite side of a new seal ring has a mark on it).
Slide it along the shaft and push it into and seat it in the bore in the volute body.
If it can not be pushed in by hand it may be tapped into place by use of a block of
wood between the ring and a hammer.
5. Wipe the face of the previously installed stationary seal ring of the mechanical
seal with a clean lint free cloth or tissue paper.
6. Wipe a few drops of seal lubricant on the inside of the bellows of the mechanical
seal and wipe the face of the carbon ring with a lint free cloth or tissue paper.
Slide the seal onto the shaft until the carbon ring contacts the stationary seal ring.
