Remove bolts (4), pipe (6) and cover assembly (5) from pump assembly. 4. Put cover assembly in vise and install tooling (A) on gear (7) and remove gear from shaft assembly. Remove shaft assembly from cover. 5. Remove bearing (8) from cover. 6. Remove bolt (10) and washer (9) from shaft assembly. 7. Install tool (B) on gear and remove gear (11) from shaft. Remove key. 8. Remove nine bolts (12) and housing assembly (13) from pump. 9. Remove bearings (14) and (15) from housing. 10. Remove manifold assembly (18) from manifold assembly (19). Remove seals (17) from each side of manifold assembly (18).11. Remove two gears (16) from shaft. 12. Remove two bearings (20) from gears (16). 13. Remove shaft assembly (21) from manifold assembly (19). 14. Use a press to remove shaft (22) from gear (23). Remove key from shaft. 15. Remove two shafts (25) from the manifold with tooling (C) as shown. Remove bearing (24) from manifold.Assemble Oil Pump
1. Lower the temperature of two shafts (1) and install in manifold. Install the bearing in the manifold (2) with tooling (A). The installed bearing must be .030 in. (0.76 mm) below the machined surface of the manifold. 2. Lower the temperature of shaft (3). Install the key in the shaft and install the shaft in gear (4) with a press until the gear makes contact with the shoulder on the shaft. 3. Put a thin layer of SAE 30 oil on the shaft assembly and bearing. Install shaft assembly (5) in manifold (2).
