APPLICATION

Marine Engine Cooling

Perkins Model 4-107 and 4-108

INSTALLATION INSTRUCTIONS

NOTICE: If installing this pump on a Perkins 4-107 or

4-108 engine, it is essential that the pump shaft is

properly aligned with the driving-shaft on the engine. If

the pump adaptor plate (Perkins Part No. 33154119) that

the pump mounts to has been loosened, it must be

realigned using a special Perkins alignment tool when it

is resecured to the engine. Contact your Perkins

Service Dealer to arrange the adaptor plate realignment.

Failure to have the adaptor plate properly aligned prior

to installing the pump can cause severe damage to the

pump and/or the engine.

Before installing the pump, note the position of the tang

on the engine's pump-driving shaft relative to the pump

mounting studs (holes). Then use a screwdriver or thin

bar inserted between the drive tabs on the pump shaft to

rotate the shaft so it will align with and engage the tang

on the engine's pump-drive.

Install a new gasket between the engine and pump

mounting flange. Then, ensuring the engine's drive tang

and the pump's drive tabs are properly engaged,

position the pump against the engine. Make certain the

pump alignment collar is properly seated in the

registration hole on the engine so the pump mounting

flange fits flush against the engine. Secure the pump

with four nuts or machine screws and lock washers.

OPERATING INSTRUCTIONS

The pump with self-prime with a lift of about three feet

at low or high speeds. Before starting engine ensure

the inlet plumbing, including the inlet through-hull and

scoop is free of blockages or debris. The inlet seacock

and any valves in the inlet plumbing must be fully open.

The water being pumped serves as a lubricant for the

flexible impeller and keeps the impeller and pump cool.

Therefore, do not run the pump dry for more than 30

seconds or the impeller and pump will likely be

damaged.

To winterize the pump, drain the liquid from the impeller

cavity by loosening the end cover screws. Lightly tap

the end cover, if necessary, to break it loose from the

body.

SERVICE INSTRUCTIONS

Impeller Replacement: Remove the end cover and end cover

gasket. Pull the impeller out of the impeller bore by grasping the

hub with a pair of water pump pliers pulling it straight out. A light

coat of grease applied to the impeller bore and ends of the

impeller will aid priming on initial engine start-up. Install a new

impeller by pushing it into the impeller bore with a rotary motion

in the direction of normal pump rotation until the impeller spline

contacts the shaft. With a firm straight inward push, seat the

impeller in the bottom of the impeller bore. Position a new

gasket and the end cover against the pump body and secure it

with the end cover screws.

Major Repair: Remove the four nuts or machine screws and

lock washers, if installed, that secure the pump mounting flange

to the engine and remove the pump to replace the shaft seal,

bearing or the shaft assembly.

Notice: If removing the pump from a Perkins 4-107 or 4-108

engine, do not loosen the four outer nuts that secure the

engine's pump adaptor plate to the timing gear cover and

engine. Loosen only the four inner nuts that secure the pump

mounting flange to the adaptor plate. If the outer adaptor plate

nuts are loosened, the plate must be realigned before the pump

can be reinstalled (see Notice: on front page).

Disassembly: Remove the end cover, gasket and impeller as

described in impeller replacement instructions. With an arbor

press and drift, press on the impeller end of the shaft to remove

the alignment collar (Key 6) and the shaft, drive coupling and

bearing subassembly. The slinger can then be removed from

the space between the impeller bore end and bearing bore end

of the body. Loosen the cam screw a couple of turns and tap it

sharply to break cam free from the top of the impeller bore.

Finish removing the cam screw and cam. Tap the pump body,

impeller end down, on a soft surfaced table to shake the

wearplate out of the impeller bore. From the drive end of the

pump, use a drift or dowel to push the shaft seal out of the seal

bore. With needle nose pliers reach into the drive end of the

PARTS LIST

pump and grasp the lip of the bearing seal to pull it from the seal

bore. If the bearing, coupling or shaft are to be replaced,

support the inner bearing race and with a small drift, press the

shaft out of the coupling and bearing.

Clean all parts and inspect them for wear. If the bearing does

not roll smoothly or had noticeable wobble between the races, it

should be replaced. If the shaft has easily detected grooves

worn under the lips of the seals, it should be replaced. If the

cam, wearplate or endcover have easily detected grooves or

wear rings, they should be replaced.

Assembly: Press the drive end of the shaft into the bearing

taking care to support the inner race of the bearing. Press the

drive coupling onto the shaft. Position a new bearing seal in the

bearing bore with the seal lip pointed toward the drive end of the

pump and push it into the seal bore. Position the slinger in the

cavity between the impeller end and bearing end of the pump.

Insert the shaft, bearing and coupling sub-assembly through the

bearing bore and slinger until the bearing contacts the body.

Taking care to press against the outer bearing race, press the

shaft assembly into the pump body until it is firmly seated. Press

the alignment collar into the bearing bore until it seats firmly

against the bearing. This should be a tight press because it

secures the bearing/shaft assembly in place.

Slide the shaft seal over the shaft with the lip pointing toward the

end cover and push it firmly into the seal bore. Drop the

wearplate into the impeller bore ensuring the positioning notch is

centered in the cam area of the bore. Apply a small amount of

non-hardening sealant to the top of the cam and place it into the

impeller bore. Ensure the pin in the cam engages the notch in

the wearplate and the cam is fully seated in the bore and

secure it with the cam screw. Using a rotary motion, push the

impeller into the impeller bore. Position a new gasket and the

end cover on the body and secure them with the end cover

screws.
