CORE AS-RADIATOR 3268696 - Caterpillar

12. Put clean oil on the two bearing cones. Install bearing cups (28) over the bearing cones to prevent damage during assembly.13. Put a bar through the differential as shown, and fasten a hoist to the bar. Put the differential in position in carrier (14). 14. Install two bearing caps (27) and four bolts (25) finger tight. Install two bearing adjuster nuts (26). Bearing adjuster nuts (26) must turn freely after they are installed.15. Tighten bolts (25) by hand four to six turns, then tighten the bolts to a torque of 149 to 197 N m (110 to 145 lb ft).16. Tighten both bearing adjuster nuts (26) evenly until there is a small amount of backlash and zero preload on the differential bearings. The correct thickness of shims (16) was determined in step 10. The correct thickness of spacer (18) was determined in step 11.17. Put a 3.2 mm (.125 in) continuous bead of 8T-9022 General Purpose Adhesive Sealant on the face of carrier (14) at the location for bearing cage (23). The sealant should go around the inner edge of all fastener holes to ensure complete sealing. Install pinion shaft (21), shims (16), bearing cage (23) and spacer (18).18. Put a 3.2 mm (.125 in) continuous bead of 8T-9022 General Purpose Adhesive Sealant on the face of gear case (6) at the location it mounts to bearing cage (23). Install gear case (6) on the bearing cage, and install eight washers and nuts (12). Tighten the nuts to a torque of 48 to 68 N m (35 to 50 lb ft).19. Install bearing cone (11), reduction drive gear (8), the washer and nut (7) on the pinion shaft. Tighten nut (7) to a torque of 407 to 542 N m (300 to 400 lb ft). 20. Use the following procedure to adjust the differential bearing preload.a. Attach Tooling (E) on the mounting flange of the carrier as shown. Position the dial indicator against the back surface of bevel gear (43). b. Loosen bearing adjuster nut (26) that is opposite bevel gear (43) so that a small amount of end play shows on the dial indicator. c. Use either of the above methods to move the differential and bevel gear to the left and right with pry bars as shown. Make note of the end play. The pry bar must not touch the differential bearings.d. Tighten the same bearing adjuster nut (26) so that no end play shows on the dial indicator. Move the differential and bevel gear to the left and right as needed, repeating step c.e. Tighten both bearing adjuster nuts one notch from the zero end play measured in step d. 21. Use the following procedure to check runout of the bevel gear.a. Attach Tooling (E) on the mounting flange of the carrier as shown. Position the dial indicator against the back surface of bevel gear (43).b. Rotate the differential and bevel gear while reading the dial indicator. The runout of the bevel gear must
