2. Temporarily install the stator in the impeller. Use the same procedure outlined in Step 1 to check the clearance between the impeller and the stator. The difference between dimension (P), the inner diameter of the impeller and dimension (Q), the outer diameter of the stator, must be 0.71 to 0.91 mm (0.028 to 0.036 inch) with new parts. The maximum permissible clearance with worn parts is 1.37 mm (0.054 inch). 3. Use a suitable measuring device to measure the outer diameter of the stator at location (S). Use a suitable measuring device to measure the inner diameter of the ring at location (R). The difference between dimension (R), the inner diameter of the ring and dimension (S), the outer diameter of the stator, must be 0.56 to 0.71 mm (0.022 to 0.028 inch) with new parts. The maximum permissible clearance with worn parts is 1.07 mm (0.042 inch). 4. If bearing race (1) has been removed, lower the temperature of the bearing race. Install in housing (2) until the race makes contact with the shoulder in the bottom of the bearing race bore. 5. Install seals (4) on piston (3) and in housing (2). 6. Install piston (3) in the housing.7. Put hub (5) in position in the housing. Install two discs (7) and two plates (6). Install the disc and plates in alternating order. Start with a disc. 8. Install plate (8) and retainer ring (9) that holds the plate in the housing. Remove hub (5) from the housing. 9. If bearing race (11) was removed, heat the race to a temperature of 135°C (275°F) and install it on the hub until the race makes contact with the shoulder on the hub. Install ring seal (10) on the hub.10. The following steps describe the procedure for assembling the hub, the turbine and the ring: a. Install hub (5) on the back of turbine (13) with two bolts to help align the ring. b. Lower the temperature of ring (X). Install ring (X) in turbine (13). c. Put hub (5) in position on turbine (13) and install the bolts. Tighten the bolts to a torque of 120 15 N*m (90 11 lb ft). Make sure ring (12) is in position in hub (5). 11. Install bearing (14) and turbine (13) in the housing. The bearing must be held in position in the housing when the turbine is installed. 12. Install race and retainer assembly (16) and bearing (15) on the hub. Be sure the notch in the race is in alignment with pin (17) on the hub. 13. Use Tooling (A) and a press to install the bearing in carrier (18). The installed bearing must be 1.52 0.51 mm (0.060 0.020 inch) below the surface of the carrier. 14. Install ring seal (19) on the carrier.
There is identification on the cam that shows "IMPELLER SIDE" of the cam.
15. Install retaining ring (20) in stator (21). Heat the stator to a maximum temperature of
