PUMP KIT-VALVE 5P2965 - Caterpillar

Start By:a. remove circle drive 1. Put the circle drive in position on blocks as shown. Remove four nuts (1), retainer housing (2) and shims from housing assembly. 2. Remove bearing cup (3) from retainer housing. 3. Remove five bolts (5) and cover (4). Remove coupling (6) and the worm gear with bearings. 4. Remove bearing (7) from cover (4). 5. Remove bearings (8) and (10) from worm (9) with tooling (A). 6. Remove gear (11) and shaft (12) as a unit. 7. Remove bolts (13) that hold the gear to the shaft. Remove the gear from the shaft. 8. Remove thrust washer (14) and bearing (15) from housing. 9. Remove the bearing cup from housing (16) with tooling (B).Assemble Circle Drive
1. Lower the temperature of bearing cup (17). Install the cup in the housing (16).2. Install the bearing in housing (16) with tooling (C) to a depth of 2.0 0.5 mm (.079 .020 in.) below the surface of housing (1). 3. Put gear (11) in position on shaft (12). Install the gear with the deeper side toward the flange on the shaft.4. Install the nuts, washers and bolts that hold gear (11) to shaft (12). Tighten bolts to a torque of 270 25 N m (200 20 lb.ft.). 5. Put thrust washer (14) in position in the housing. 6. Put the shaft and gear assembly (17) in position in housing (16). 7. Heat bearings (7) and (9) to a maximum temperature of 135° C (275° F).8. Install bearings (8) and (10) on worm (9).9. Put worm (9) and the bearings in position in housing (16). Make sure bearing (10) is in contact with the bearing cup in housing (16). 10. Lower the temperature of bearing cup (3) and install in the retainer housing (2). 11. Put retainer housing (2) in position on the circle drive housing. Do not install the O-ring seal or the shims. Install the nuts that hold the carrier housing to the circle drive housing.12. Install tooling (D) on the carrier housing and against worm (9). Tighten nuts (1) evenly while worm (9) is moved. Tighten nuts (1) until the shaft end play is zero. Measure the distance between retainer housing (2) and the circle drive housing with a feeler gauge. Remove retainer housing (2) and tooling (D).13. Torque nut (1A) to 20 N m (15 lb ft) and nut (1B) to 40 N m (30 lb ft). Then, torque nut (1A) to 80 N m (60 lb ft) and nut (1B) to 80 N m (60 lb ft). Rotate the worm 3 revolutions then back off the nuts. Torque nut (1A) to 20 N m (15 lb ft) and nut (1B) to 40 N m (30 lb ft) and then torque nut (1A) to 40 N m (30 lb ft). Rotate the worm 3 revolutions. Torque nut (1A) to 40 N m (30 lb ft) and nut (1B) to 40 N m (30 lb ft). Measure the average gap
