2. Remove the check valve from the volute. Remove
the one upper and two lower volute screws, and
remove the volute. Save all for later use.
3. Remove the impeller bolt from the impeller and
discard. Remove the impeller and keyshaft
carefully, using a pry bar if necessary. Save for
later use.
INSTALLATION INSTRUCTIONS
Disassembly Instructions
1. Remove the 10 body screws, lock washers, and
nuts from the pump assembly. Remove the body
from the pump assembly. Save all for later use.
CAUTION
Use standard methods and practices when
installing equipment, including proper
personal protective safety equipment.

7. Using a round object such as a wrench socket, tap
gently with a hammer to remove the carbon seal
half from the rear bracket. The seal is very fragile;
take care not to crack the seal if it will be reused.
8. While the pump is completely disassembled, clean
all of the reusable parts thoroughly, removing any
traces of old gasket material and trapped or dried
liquids that were run through the pump.
With the four bracket screws removed, the rear
bracket and reservoir can now be removed from
the drive unit.
4. Insert the supplied 7/16" cap screw into the
impeller snout. As the cap screw is tightened, the
impeller will be pried off the shaft of the drive unit.
Remove the 7/16" cap screw once the impeller has
been removed from the drive unit.
5. If the pump impeller is to be reused, the ceramic
seal half (Item #6 on page 3) should be removed
from the impeller at this time. The impeller key
(Item #16 on page 3) that is located behind the
ceramic seal half should also be replaced at this
time.
6. Remove the four bracket screws, rear bracket
washers, and screw head O-rings from the rear
bracket using a 1/2" socket.
Remove 4 bracket screws,
rear bracket washers, and
screw head O-rings.

2. Place the seal O-ring behind the lip of the spring
half of the seal assembly. Install the seal assembly
half into the rear bracket using a tool such as
a 1-1/2" pipe nipple or arbor press to give even
pressure on the metal flange of the seal housing
during installation. Gently press the seal into
position until it bottoms.
3. Place a flat washer and screw head O-ring on
each of the four 5/16" x 1-3/4" cap screws. Install
the rear bracket onto the engine using the bracket
screw assemblies from the previous step. The
handle of the rear bracket should be to the top of
the drive unit. Tighten securely.
9. Polish the drive unit shaft to remove any corrosion
that may have formed. Clean the engine mounting
surface of any debris, and polish if necessary.
Assembly Instructions
1. Install the pump slinger on the drive unit shaft. The
slinger should be slid all the way back on the shaft
of the drive unit so that the slinger covers the step
on the drive unit shaft as shown.

6. Install the O-ring segment and O-ring -375. Lightly
coat with silicon grease to secure.
7. Reinstall the volute onto the rear bracket using
the three volute screws. Reinstall the check valve
onto the snout of the volute. The drive unit should
be turned over a few times to check for clearance
between the impeller and volute. A small amount
of drag between the impeller and volute will cause
no problem; however, if the drive unit will not turn
over because of the lack of clearance, a shim may
have to be used.
4. Install the ceramic seal half into the impeller
rubber first, with the ceramic surface facing
out. The seal half is pressed into the hub of the
impeller by using an arbor press or similar tool
that will provide a uniform press fit. The outside
diameter of the rubber boot may be sparingly
coated with silicone grease to ease installation.
Be absolutely sure that the ceramic seal half
is bottomed out and installed squarely. If the
installation is not square, seal wobble will occur,
leading to premature seal failure. Care must be
used when handling the seal to not scratch the
seal surface.
5. Install the impeller key shaft and impeller onto the
engine drive shaft. Secure the impeller to the drive
unit shaft with the impeller bolt gasket and the
5/16" x 1-1/8" hex flange cap screw. Tighten the
cap screw until snug.

WARNING
Gasoline is highly flammable and gasoline
vapor is explosive. Never smoke while
working on the equipment. Keep all open
flames away from gasoline tank and lines.
Wipe up any spilled gasoline immediately.
WARNING
Do not use the pump with flammable or
other hazardous liquids. Failure to follow
this warning may result in explosion, bodily
injury, or death. Read and follow the safety
precautions in the engine owner's manual.
8. Reinstall the pump body with the outlet flange
facing up. Reinstall the 10 body screws, 10 lock
washers, and 10 nuts to secure the pump body to
the rear bracket. Tighten the cap screws securely
all the way around.
9. The pump is now ready for operation.
Reinstall the 10 body screws and secure
with 10 lock washers and 10 nuts.
OPERATING INSTRUCTIONS
NOTE: The gas engine is shipped without oil
in it. Do not operate the gas engine until it has
been filled with oil. Consult the engine owner's
manual for oil specifications and maintenance
procedures.
NOTE: To avoid premature pump seal failure,
NEVER run the pump dry. Prime and fill the pump
with the fluid being pumped before starting the
unit.
• Ensure that hose and pipe connections are air
tight. An air leak will reduce pump capacity and
may prevent priming.
• Place the pump and engine on a level foundation,
positioned as close to the liquid tank as possible.
• Keep the suction line short and position it with few
bends.
• Install a pump strainer on the suction line when
pumping dirty water or liquids that contain solids.
CAUTION
Read the engine manufacturer's manual
before operating the Gas Engine Transfer
Pump.

Pump Priming
NOTE: Running the pump with no liquid will cause
damage. Make sure the pump is primed before
operation.
Make sure the circulation pump is appropriately
primed every time the unit is started. If the pump
does not automatically prime within 20 seconds of the
circulation pump starting (no visible churn in the liquid
being pumped), stop the unit and manually prime the
pump following the instructions below.
Manual Pump Priming
1. Remove the pump plug and fill the chamber with
at least 64 oz of water or brine.
Pump
Plug
2. Replace the plug and jog the pump for a few
seconds to remove any air in the circulation
system.
3. Repeat Steps 1 and 2 until the pump is primed.
The liquid in the mixing tank will begin to
noticeably churn once the pump is primed.
Maintenance and Storage
• There is no need to lubricate the pump. The seal is
lubricated and cooled by the fluid that is pumped.
• Drain the pump body after use if there is a danger
of freezing.
• If the engine will be unused for long periods of
time, drain the pump, leave the fill and drain plugs
out of the pump, and store the unit in a heated, dry
building.
• See the engine manual for further instructions.
