SHAFT-BEVEL PINION 6W1905 - Caterpillar

(5) Torque for bolts that hold retainer to axle housing ... 270 25 N m (200 18 lb ft)(6) Torque for 30 bolts (with 2P-2506 Lubricant on faces of washers and bolt threads) ... 470 30 N m (350 22 lb ft) Rubber toric seals and all surfaces in contact with them must be clean and dry at assembly. Put a thin layer of oil on the surfaces of the metal seals that are in contact just before installation. Put lubricant on all other seals at assembly.Wheel Bearing Adjustment:
Before adjustment of the wheel bearings is started, check to be sure the bearing cups have a tight seat against the bottom of the bore in the wheel. Use a 0.03 mm (.001 in) or 0.05 mm (.002 in) feeler gauge to check for any clearance behind the bearing cup. If any clearance is found, use a bearing driver or press to move the bearing cup until it has a tight seal with no clearance.1. Put the wheel and bearings in position on the axle housing.2. Install the hub and ring gear.3. Install retainer (1) without shims (4). Use four bolts as shown.4. While the wheel is turned, tighten the bolts in a radial (circular) pattern to 35 N m (25 lb ft). Tighten each bolt one time only.5. While the wheel is turned, tighten the bolts in a radial (circular) pattern to 70 N m (50 lb ft). Tighten each bolt one time only.6. Use a depth micrometer (2) to measure through the holes with threads in the retainer and find the average depth.7. Use an outside micrometer (3) to measure the thickness of the retainer at the holes with threads and find the average thickness.8. Find the difference between the two average measurements. This difference is the distance between the end of the axle housing and the retainer.9. Remove retainer. Install enough shims (4), between the axle housing and the retainer, so their thickness is 0.127 mm (.005 in) more than the distance found in Step 8.10. Install retainer (1). While turning the wheel, tighten the bolts that hold retainer to the axle housing to a torque of ... 270 25 N m (200 20 lb ft)
