TM 5-3805-260-24DIFFERENTIAL LOCK(1) Torque for two bolts ............32 t 5 lb ft (43 7 N-m)(2) Torque for four bolts ............75 + 10 lb ft (100 14 N m)(3) Torque for two bolts ............32 - 5 lb. ft (43 7 N-m)Do not bend lock wire over top of bolts(4) Torque for ten bolts ..............325 lb ft (43 7 N-m)Bend locks against sides of heads of bolts (4) Not aroundcorners.(5) 8D2583 Springs (twelve).Length under test force .............2 41 in (37 2 mm)Test force ..................................7.75 3.9 lb. (344.7 ± 17.4 N)Free length after test .................2.96 in (75.1 mm)Outside diameter ........................927 in. (23.6 mm)FINAL DRIVENOTE: Rubber toric seals (1) and all surfaces in contact withthem must be clean and dry at assembly. Put a thin layer of oilon the surfaces of the metal seals that are in contact just beforeinstallation. Put lubricant on all other seals at assembly.(2) Torque for the bolts that hold the carrierto the wheel ..................195 + 18 lb. ft. (265 + 25 N m)(3) Torque for the bolts that hold the brake discto the wheel ..................165 20 lb. ft. (224 27 N m)(5) Torque for bolts that hold the rimto the wheel .................. 365 50 lb. ft. (496 ± 68 N m)Adjustment Procedure for Wheel Bearings:1. Tighten nut (4), while the wheel is turned slowly, untiltorque needed to turn wheel is160 + 50 lb in. (18 6 N m)Procedure to Check Wheel Bearing Adjustment:1. Install a torque wrench 6n nut (5), to check torque neededto turn wheel.a. If an 8 in. (203 mm) long lb. in. (N m) 9S7354 TorqueWrench 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 TorqueWrench is used.Torque read must be .... 70 22 lb. in. (83 N m)c. Use this formula to get the correct torque reading forother lb. in. (N m) torque wrenches.C = A*TA*B"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 t 50 lb. in. (18 -6 N m)].NOTE: Torque wrench must be installed on nut (5) so it is in line with thecenter of the wheel.2.If torque read at nut (5) is not correct, make adjustments at nut (4).1-50
