VALVE-SOLENOID 1974048 - Caterpillar

The bearing cone will be pushed into correct position when the pinion is installed.3. Install Duo-Cone seal (34) with tool (A) in retainer (33). The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, put oil on the contact surfaces of the metal seals. 4. Install O-ring seal (32) in retainer (33). Install the retainer on the shaft. 5. Put 2P2506 Anti-Seize Compound on the shaft and pinion splines. Install pinion (31) on the shaft. Install retainer (30) on the pinion. 6. Use a press and push the bearing cone and gear into position on the shaft. The pinion and bearing cone are in correct position when the retainer is against the end of the shaft. 7. Remove retainer (30). Put lubrication on the O-ring seal and install O-ring seal (41). Install the retainer. Install the lock and three bolts that hold the retainer. Tighten the bolts a small amount. 8. Lower the temperature of bearing cup (37). Install the bearing cup in cartridge (27). 9. Turn the cartridge over. Lower the temperature of bearing cup (42). Install the bearing cup in the cartridge.10. Install Duo-Cone seal (43) with tooling (A) in the cartridge. The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, put oil on the contact surfaces of the metal seals. 11. Lower cartridge (27) into position on the shaft. 12. Heat bearing cup (42) to a maximum temperature of 135° C (275° F). Put the bearing cone in position on the shaft. 13. Install the gear on the shaft. Put three pieces of solder (13) with a diameter of 1.50 mm (.059 in) on the end of the shaft between the bolt holes as shown. Install retainer (44) and the three bolts that hold the retainer. Tighten the bolts to 60 lb in (6.8 N m). Remove the bolts and the retainer. Measure the thickness of the solder.
Put the retainer and bolts in position on the shaft to hold the gear in position while the unit is put on tool (B). The gear can fall off the shaft if the bolts and retainers are not used to hold it and serious personal injury can be the result.
14. Fasten a hoist to the cartridge and put the cartridge in position on tool (B). Install shims (45) that are the same thickness as the average thickness minus 0.10 to 0.18 mm (.004 to .007 in).15. Install retainer (25) on the end of the shaft. Install the lock and two of the bolts that hold the retainer in place. Tighten the two bolts a small amount. Put a 5/8" - 11 NC forged eyebolt in the other bolt hole. 16. Tighten the pinion bolts on the other end of the shaft to a torque of 550 60 lb ft (750 80 N m). Bend the locks. 17. Lower the temperature
