HOSE 1844240 - Caterpillar

31. Remove washers (54) from end plate (53).32. Remove O-ring seals (55) from cylinder (56).33. Remove cylinder (56) from motor housing (3). Remove the remainder of the O-ring seals from the cylinder. ASSEMBLE AIR STARTER
Clean all parts thoroughly. Put 2S3230 Bearing Lubricant on all bearings and the drive assembly. Put a thin layer of SAE 10W oil on all other parts before assembly.1. Install O-ring seals (1) on cylinder (2) and install the cylinder in housing (3). Make sure pin (5) is in alignment with opening (slot) (4) in housing (3). 2. Install O-ring seals (6) on cylinder (2).3. Install end plate (7) on rotor (8).4. Install O-ring seal (9) on the rotor shaft.5. Install bearing (10) over the rotor shaft and in the end plate. 6. Install nut (11) on the rotor shaft with the shoulder toward the bearing.7. Tighten the nut until there is .02 mm to .07 mm (.001 in. to .003 in.) clearance between the end plate and the rotor. Use a feeler gauge to check the clearance. Tighten bolt (12) and check the clearance again. Step 8 is for right hand rotation starters only. For left hand rotation starters, the rotor is installed with the pinion end of the rotor away from the cylinder alignment pin.8. Install rotor (8) in motor housing (3) with the pinion end of the rotor toward the cylinder alignment pin. Make sure pin (13) is in alignment with the hole in the end plate.9. Install vanes (14) in the rotor. 10. Install end plate (15) on the rotor and make sure hole (16) in the end plate is in alignment with pin (17).11. Install washers (18) in the end plate.12. Put bearing (19) in position on the end plate.13. Use tooling (B) and a press to install bearing (19) on the rotor shaft and in the end plate. 14. Install rotor pinion (20) and the bolt that holds it to the rotor shaft. Tighten the bolt to a torque of 120 N m (90 lb.ft.).15. Install O-ring seal (22) around the rotor bearing and put cover assembly (21) in position on motor housing.16. Put bearing (25) and ring (23) in position on drive shaft (24).17. Use a press and tool (A) to install the ring on the drive shaft. 18. Put bolt (30), lockwasher (31), washer (32), bearing (33), driving clutch jaw (34), driven clutch jaw (26), spring (27) and cup (28) in position in drive shaft assembly (24) and install ring (29) in the drive shaft assembly.19. Use tooling (B) to install the seal in piston (35). Make sure the lip of the seal is toward the outside of the piston as shown. Later model air starters will not have bumper (36).20. Install O-ring seal (37) and bumper (36) on piston (35).21. Install piston (35) on drive shaft assembly (24) and install ring (38) that holds the piston to the shaft assembly. 22. Install O-ring seals (39) on bulkhead
