DIFFERENTIAL LOCK
(1) Torque for two bolts ............. 32 ± 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 .............. 32 ± 5 lb. ft. (43 ± 7 N•m)
Bend locks against sides of heads of bolts (4). Not
around corners.
(5) 8D2583 Springs (twelve):
Length under test force .................... 2.41 in. (37.2 mm)
Test force ...................... 77.5 ± 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 DRIVE
NOTE: 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.
(2) Torque for the bolts that hold the carrier
to the wheel ...................... 195 ± 18 lb. ft. (265 ± 25 N•m)
(3) Torque for the bolts that hold the brake disc
to the wheel ....................... 165 ± 20 lb. ft. (224 ±27 N•m)
(5) Torque for bolts that hold the rim
to 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, 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.
A x T
C =
A+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. CT = 160 ± 50 lb. in. (18 ± 6
N•m)].
NOTE: 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 (4).
