GLASS-FIXED 3551139 - Caterpillar

ADJUSTMENT PROCEDURE:1. Install pinion (6) in housing (5) complete with bearings.2. Install washer (4), lock and locknut (3) on pinion (6).3. Tighten locknut (3), until the end play of pinion (6) is approximately ... .012 in.(0.30 mm)4. Install yoke assembly (1) against locknut (3).5. Install retainer and bolt (2). Tighten bolt (2) to ... 265 35 lb. ft.(360 45 N m)6. Check the end play of pinion (6) again.7. With yoke, retainer, and bolt (2) installed the correct end play for pinion (6) is ... .002 to .005 in.(0.05 to 0.13 mm)8. If the end play is not correct, the yoke assembly must be removed and nut (3) adjusted. Then do Steps 4 thru 7 again.9. Assemble differential in a vertical position with the teeth of the ring gear toward the top, as shown. FOR TORQUE VALUES NOT GIVEN, SEE THE FIRST PAGE OF SPECIFICATIONS FOR GENERAL TIGHTENING TORQUES 10. Do not tighten adjustment ring (8).11. Tighten adjustment ring (11) until the amount of free movement (backlash) between ring gear (7) and pinion (6) is ... .014 .005 in.(0.36 0.13 mm)12. Tighten adjustment ring (8), while ring gear (7) is turned. Tighten until a small resistance is needed to turn the ring gear.13. Install a dial indicator so the tip of the indicator is in contact with the upper bearing cap.14. Tighten adjustment ring (8) until distance (A), between the differential case and the bearing cap, increases by ... .018 .002 in.(0.46 0.05 mm) An increase in distance (A) will give the preload for the bearings.15. Measure the backlash between the ring gear and pinion again. The backlash must be ... .014 .005 in.(0.36 0.13 mm)16. If the backlash is too much, loosen adjustment ring (8) and tighten adjustment ring (11) the same amount.17. If the backlash is not enough, loosen adjustment ring (11) and tighten adjustment ring (8) the same amount. Differential bearing preload will not change if you loosen one ring and then tighten the other ring the same amount.(10) Torque for bolts (with lubricant on the threads) ... 350 35 lb. ft.(470 45 N m)18. After the backlash and preload adjustments have been made, the tooth contact between pinion (6) and ring gear (7) must be checked, as follows: a. Put a small amount of Prussian blue, red lead, or paint on the teeth of ring gear (7).b. Turn pinion (6) in both directions.c. The correct area
