TIE ROD 2172916 - Caterpillar

(10) Torque for six bolts in retainer ... 135 15 N m (100 11 lb ft)(12) Torque for 21 bolts in ring gear ... 270 25 N m (200 18 lb ft)(14) Torque for 20 bolts in carrier ... 475 50 N m (350 37 lb ft) Adjustment Procedures:1. Install pinion (7) in cage (6) complete with bearings.2. Install spacer (5) and yoke assembly (1). Put retainer and bolts (3) in place. Tighten bolts to a torque of ... 175 20 N m (130 15 lb ft)3. Remove the bolts and retainer. Measure dimension (4) from the end of the pinion shaft to the yoke.4. Add 0.20 0.05 mm (.008 .002 in) to the measurement. The total is the thickness of shims (2) required.5. Install the correct thickness of shims (2). Install the retainer and bolts (3). Tighten the bolts to a torque of ... 270 25 N m (200 18 lb ft)6. The end play of the pinion shaft must be ... 0.20 0.05 mm (.008 .002 in)7. Assemble differential and bevel gear group in carrier assembly (15) with the axle centerline in the vertical position and the teeth of ring gear (11) toward the top, as shown. Turn adjustment rings (8) and (13) so that there will be free movement (backlash) when the pinion is installed.8. Install the pinion and cage (6) in carrier assembly (15) with 80% of shim pack (9).9. Torque one of two bolts in each bearing cap to 70 N m (50 lb ft), the other at 5 N m (4 lb ft).10. Move adjusting nuts (8) and (13) to a position that maintains gear backlash but not tight gear mesh and slight bearing end play.11. Measure the torque required to rotate pinion (7) and record the measured torque.12. Move adjusting nut (13) while rotating bevel gear (11) to zero backlash position. Move adjusting nut (13) back to the nearest lock position. (Maximum back off movement one lug on adjusting nut).13. Move adjusting nut (8) until the torque to rotate pinion (7) is increased 0.6 to 1.1 N m (5.3 to 9.7 lb in) over pinion (7) torque in Step 11. This is the seated position.14. Move adjusting nut (8) three lugs to the nearest lock position.15. Measure the backlash between ring gear (11) and pinion gear (7). The backlash must be 0.36 0.12 mm (.014 .005 in).16. If the backlash does not meet specification, retract one nut the same amount the opposite nut is advanced to keep the bearing preload.17. Torque bearing cap bolts (16) to 1125 100 N m (820 75 lb ft).18. Measure overall rolling torque at pinion (7). It should read 5.6 to 9.0 N m (49.56 to 79.65 lb in).19. After the backlash and preload adjustments have been made, the tooth contact between pinion (7) and ring gear (11) must then be
