11. Use a hammer and punch from the opposite side of gear (9) to remove retainer (12) and bearing

(11).

12. Remove pilot (13) from the torque converter housing.

13. Remove the bolt and retainer (14) from the torque converter shaft.

14. Turn the torque converter over and remove ring (15) from the carrier. Remove bolts (18).

15. Install four 5/16"-18 NC forcing screws and remove impeller (17) from housing (19). The bearing

and one half of its inner race will come off the opposite end of shaft (16) when the impeller is removed.




6/14

16. Hit the end of shaft (16) with a soft faced hammer as shown to remove the second half of the inner

bearing race.

17. Remove turbine (20) from impeller (17) and shaft.

18. Remove ring (23) from shaft (16) with tool (A).

19. Remove six bolts (22), the two plates under bolts (22) and guide wheel assembly (stator) (21).

20. Remove impeller (17) and the gear as a unit from shaft (16).

21. Remove bolts (24) and the two plates to remove the gear from impeller (17).




7/14

22. After gear (25) is removed from the impeller, use tool group (B) and a press to remove the bearing

from the gear.

23. Remove shaft (16) and the bearing from carrier (26) with a soft faced hammer.

24. Use tool (A) to remove ring (27) that holds bearing (28) on shaft (16).

25. Use a press and tool (C) to remove bearing (28) from the shaft.




8/14

26. If necessary, remove seal ring (29) and pin (30) from shaft (16).

27. If necessary, remove sleeve (32) and pins (31) from carrier (26).

Assemble Torque Converter

NOTICE

Before the torque converter is assembled, see Torque Converter

Clearance Checks. These clearances must be correct for the torque

converter to operate with efficiency.

1. Install pins (1) and sleeve (2) in carrier (3). Install the sleeve until it makes contact with the

counterbore in the carrier. Make sure the tab on sleeve (2) fits in the groove of the carrier.




9/14

2. Install the pin in the end of shaft (5). Install seal ring (6) on shaft (5).

3. Heat bearing (4) to a maximum temperature of 275F (135C). Install the bearing on shaft (5). Use

tool (A) and install the ring that holds bearing (4) to shaft (5).

4. Put carrier (3) in position on the bearing and shaft (5) as shown. Install ring (7) to hold the bearing in

carrier (3).

5. Use tool (B) and a press to install bearing (9) in gear (10). Install the bearing until it is even with the

surface of the gear shown.

6. Put impeller (8) in position on gear (10) and install the eight bolts and two plates to hold them

together. Tighten the bolts to a torque of 20 1 lb.ft. (25 1 Nm).




10/14

7. Install impeller (8) and the gear in position on carrier (3) as shown.

8. Put guide wheel assembly (stator) (11) in position in impeller (8). Install the two plates and six bolts

that hold stator (11). Tighten the bolts to a torque of 20 1 lb.ft. (25 1 Nm).

9. Use tool (A) to install the ring that holds turbine (12) in position on shaft (5). Install turbine (12) on

shaft (5).

10. Heat one half of the inner race, for the bearing assembly, to a maximum temperature of 275F (135

C). Install the race on shaft (5) with the groove up as shown.

11/14

11. Install the impeller, turbine and shaft in housing (13) as shown. Tighten the bolts that hold the

impeller to the housing to a torque of 20 1 lb.ft. (25 1 Nm).

12. Turn the torque converter assembly over. Install the ring on bearing (14) and install the bearing in

housing (13) as shown. Make sure the bearing is in correct contact with the inner half of the race.

13. Heat the other half of the inner bearing race to a maximum temperature of 275F (135C). Install the

inner half of the race with the groove toward the inside until it makes contact with the first inner race

installed.

14. Install the retainer and bolt on the end of the shaft. Tighten the bolt to a torque of 81 4 lb.ft. (111

5 Nm).




12/14

16. Put retainer (17) on gear (18).

15. Install pilot (15) on housing (13). Tighten the bolts to a torque of 36 2 lb.ft. (46 3 Nm).

17. Heat bearing (16) to a maximum temperature of 275F (135C). Install bearing (16) on gear (18).

Install the ring that holds bearing (16) in position.

18. Install gear (18) in torque converter housing (19) as shown. Tighten the three bolts that hold the gear

retainer to the housing.

19. Heat bearing (20) to a maximum temperature of 275F (135C). Install bearing (20) on gear (21).

Install the ring that holds bearing (20) in position.




13/14

20. Put gear (21) in housing (19) as shown. Install the lock and bolt in location (22) to hold gear (21) in

position.

21. Fasten a hoist to housing (19) with two 3/8" - 16 NC forged eyebolts. Put housing (19) in position

on the torque converter assembly so that the bolt holes in the housing are in alignment with the bolt

holes in the carrier.

NOTE: Make sure the teeth of gear (18) are engaged correctly with the teeth of the gear fastened to the

impeller or housing (19) can not be installed all of the way on the torque converter.

22. Install the bolts and washers that hold housing (19) to the carrier. Tighten the bolts to a torque of 40 5 lb.ft. (55 7 Nm).

23. Install gear (23) on the torque converter shaft as shown. Install the retainer and bolt to hold gear

(23). Tighten the bolt to a torque of 81 5 lb.ft. (111 7 Nm).
