3. Disconnect hose (4).4. Disconnect both hoses from elbow (2).5. Remove elbow (2).6. Remove the bolts that hold pipes (1) and (5) to the water pump.7. Install a hoist on the water pump. Remove nuts (3). Remove the water pump. Weight is 85 lb. (38.6 kg).Install Water Pump
1. Use a hoist to install water pump (2) on the engine. Install the nuts that hold it in place.2. Install pipes (1) and (4) on the water pump.3. Install the elbow (not shown) on the water pump.4. Install both hoses on the elbow.5. Install hose (3) on the elbow.6. Install coolant in the engine cooling system to the correct level. See the LUBRICATION AND MAINTENANCE GUIDE.7. Install front lower guards.Disassemble Water Pump
start by:a) remove water pump1. Remove the elbow and housing from the pump body. 2. Loosen bolt in the impeller 1/8 in. (3.18 mm). Install tooling (A) with two 5/16 in. and two 3/8in. flat washers on the bolts in tooling (A). Loosen the impeller on shaft. Remove tooling (A) and impeller.3. Remove the rubber seal and wear ring under the impeller. 4. Loosen bolt in the drive gear 1/8 in. (3.18 mm). Install tooling (B) and loosen the drive gear on shaft. Remove tooling (B) and drive gear.5. Remove the bolts, locks and bearing retainer from the pump body. 6. Turn the body over and put it in on two blocks. Push the shaft (1) and bearings out of the pump body with a plastic hammer. 7. Remove bearings (2) and spacer (3) from shaft.8. Remove the carbon ring and rubber seal from the seal case. Remove the seal case from the pump body with tooling (C).9. Remove the lip seal from the pump body with tooling (D).Assemble Water Pump
1. Install the lip seal in the pump body with tool (A). The lip of the seal must be toward the gear when installed. Put clean engine oil on the lip of seal. 2. Install the seal case in pump body with tool (B) and a press. Make sure that the seal case is down against the seat. Be careful not to damage the seal case. Use 8M8060 Quick Cure Primer and 7M7456 Bearing Mount to hold the seal case in the counterbore in the housing.
The guard has been removed from the press for better illustrations.
3. Install the bearings and spacer on the shaft. Put clean engine oil on the bearings. 4. Install the shaft and bearings in the pump body. Use retainer (2) and four bolts without locks to push the bearings into their correct position in the pump body. Install locks on bolts.5. Install gear (1) on shaft. Tighten the bolt in the gear to a torque of 150 20 lb.ft. (203.4 27.1 N m).6. Install rubber seal and carbon ring (6) in seal case (5). Carefully bend the small parts (tabs) of case in to hold the carbon ring in the case.
Do not damage or put hands on wear surface of the carbon ring or wear ring.
7. Install wear ring (4) and rubber seal (3). The smooth surface of wear ring (4) must be toward the carbon seal when installed.8. Install the impeller. Tighten the bolt in the impeller to a torque of 34 3 lb.ft. (46.1 4.1 N m).9. Install the pump body in the housing with the flat place on pump body in alignment with the fitting in housing.end by:a) install water pump
