REMOVING AND DISASSEMBLING

„

NOTE: A bleed hole is located at the bottom of

the water pump housing. If there are any signs of
coolant leakage from the bleed hole, the water
pump seals must be replaced. When servicing the
water pump, use Water Pump Bearing and Seal Kit
(p/n 0644-084).

1. Mark the three expansion chambers for assembly

purposes; then remove the expansion chambers

from the engine compartment.

2. Attach a long piece of fuel hose to the engine

coolant drain (located on the front lower half of

the crankcase). Route the fuel hose outside the

engine compartment and into a container. Open

the drain and remove the filler cap. Once the

coolant stops flowing, remove the hose and tighten

the drain valve.

3. Remove the coolant hose from the water pump

cover.

4. Remove the water pump cover and account for the

Loosen the carburetor flange clamps; then remove

the three carburetors and lay to the side.

6. Remove the cap screws securing the engine to the

front-end assembly. Remove the hose from the

thermostat housing and tip the engine forward.

7. Remove the screws securing the oil pump and pull

the oil pump from the engine. Leave the oil pump

hose and cable attached.

8. Remove the cap screw securing the impeller.

9. Pull the impeller from the shaft. If the impeller

wont slide off the shaft, start the cap screw into the

shaft and tap on the cap screw driving the shaft

back out of the impeller.

AN232

10. Remove the oil pump retainer and shaft from the

opposite side of the crankcase. Account for the

thrust washer located between the retainer and

shaft flange.
