HARNESS AS 8W3570 - Caterpillar

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.(1) Torque for studs in scraper frame ... 350 40 N m (260 30 lb ft)(2) Torque for nuts (with 5P3931 Anti-Seize Compound on the faces of the washers and threads of the studs) that hold the wheel group to the scraper frame ... 710 25 N m (525 20 lb ft)(3) Torque for 20 bolts, that hold the retainer to the spindle housing ... 250 15 N m (185 11 lb ft)(4) Torque for studs, that hold the brake drums to the wheels (earlier version) ... 160 20 N m (120 15 lb ft)Torque for bolts, that hold the brake drums to the wheels (later version) ... 250 13 N m (185 10 lb ft)Adjustment Of Wheel Bearings (On Machine)
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 five bolts as shown.4. While the wheel is turned, tighten the bolts to 35 N m (25 lb ft). Tighten each bolt one time only.5. While the wheel is turned, tighten the bolts 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 0.25 mm (.010 in) more than the distance found in Step 8.10. Install retainer (1). While turning the wheel, tighten the ten bolts that hold retainer to the axle housing to a torque of ... 250 15 N m (185 11 lb ft)
