SUSPENSION AS 3G0189 - Caterpillar

Rubber toric seals (1) 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.Torque for fill plug ... 75 5 lb. ft.(100 7 N m)Torque for drain plug ... 15 5 lb. ft.(20 7 N m)(1) Torque for 1/2 in. (12.7 mm) bolts that hold the brake disc to the wheel ... 94 10 lb. ft.(130 14 N m) Torque for 5/8 in. (15.9 mm) bolts that hold the brake disc to the wheel ... 195 20 lb. ft.(265 25 N m)(2) Torque for the bolts that hold the carrier to the wheel ... 195 18 lb. ft.(265 25 N m)(3) See ADJUSTMENT PROCEDURE FOR WHEEL BEARINGS.(4) Torque for bolts that hold wheel spindle to axle housing ... 225 25 lb. ft.(300 35 N m)(5) Torque for the nuts that hold the rim to the wheel ... 345 30 lb. ft.(465 40 N m) Adjustment Procedure for Wheel Bearings:1. Tighten nut (3), while the wheel is turned slowly, until torque needed to turn wheel is ... 160 50 lb. in.(18 6 N m) Procedure to Check Wheel Bearing Adjustment:1. Install a torque wrench on nut (5) to check torque needed to turn wheel. a. If an 8 in. (203 mm) long lb. in. (N m) 9S7354 Torque Wrench is used.Torque read must be ... 75 25 lb. in.(9 3 N m)b. If a 7 in. (178 mm) long lb. in. (N m) 9S6331 Torque Wrench is used.Torque read must be ... 70 22 lb. in.(8 3 N m)c. Use this formula to get the correct torque reading for other lb. in. (N m) torque wrenches. "C" is the reading on the torque wrench."A" is the length of the torque wrench."B" is the distance from the center of the wheel to nut (5)."T" is the torque on bearings. [T = 160 50 lb. in. (18 6 N m)]. Torque wrench must be installed on nut (5) so it is in line with the center of the wheel.2. If torque read at nut (5) is not correct, make adjustments at nut (3).
