3. Remove four elbow-to-pump retaining bolts (2).
4. Remove pump-to-timing plate retaining bolts (3).
5. Remove jacket water pump-weight 51 lbs. (23,13 kg).
Install Jacket Water Pump
1. Position jacket water pump-to-timing plate and install retaining bolts.
2. Install four elbow-to-pump retaining bolts.
3. Position water inlet line to jacket water pump and install mounting bolts. Tighten water bypass hose clamp.
4. Refill jacket water pump cooling system.
Disassemble Jacket Water Pump
preparatory step:
a) remove jacket water pump
1. Back the gear retaining nut off flush with the end of the shaft. Install tool (A) and separate gear (1) from the shaft.
2. Remove the retaining nut and gear. Remove the key from the shaft.
3. Remove the water pump housing cover retaining nuts. Install two 3/8"-16 NC forcing screws and remove the housing cover.
4. Back the impeller retaining nut off flush with the end of the shaft. Install tool setup (B) and separate the impeller from the shaft.
5. Remove the retaining nut and impeller (2).
6. Remove rubber seal (4) and steel ring (5) from the shaft.
7. Separate the bearing cage and shaft assembly (3) from the water pump housing (6).
8. Remove the carbon seal assembly (7) from the water pump housing.
9. Remove the bearing retaining ring (8) from the bearing cage. Remove the bearing and shaft assembly from the bearing cage.
10. Press the bearings and spacer off the water pump shaft.
11. Remove the oil seal from the bearing cage.
Assemble Jacket Water Pump
1. Install the bearings and spacer on the water pump shaft.
2. Install bearing and shaft assembly in the bearing cage. Install the bearing retaining ring.
3. Wrap a thin sheet of plastic or metal (1) around the water pump shaft. Lubricate the lip of the seal with clean SAE 30 engine oil. Slide the seal (2) over the shaft with lip of seal facing toward the bearing. Press the seal into the bearing cage using tool setup (A).
4. Using tool setup (A) install the water pump seal assembly (3).
5. Connect the water pump housing and the bearing cage assembly.
6. Install seal (5) and ring (4) on the water pump shaft so the polished surface of ring will contact seal assembly (3).
7. Install the impeller, washer and retaining nut. Tighten the retaining nut to 55 lb. ft. (7,6 mkg).
8. Install the water pump cover (6) with no O-ring and no gaskets. Measure the clearance between cover and impeller with feeler gauge (7).
9. Add gaskets as necessary to obtain .005" to .020" clearance. After this clearance has been obtained, remove the cover and install the O-ring and install the cover and recheck the clearance.
10. Heat the water pump drive gear in oil to 300°F (149°C). Install the key in shaft and install drive gear. Install washer and drive gear retaining nut. Tighten the retaining nut to 60 lb. ft. (8,3 mkg) and install cotter pin.
