Step 29: Torque cap screws to 30 Ib - ft (40.67 Nm).
Step 30: Rotate hub one revolution clockwise and one revolution counterclockwise.
Step 31: Check to determine if 30 Ib - ft (40.67 Nm) of torque is maintained. If value has fallen below 30 Ib - ft
(40.67 Nm), torque and rotate. Continue this until 30 Ib - ft (40.67 Nm) is maintained on all cap screws after
hub has been rotated.
Step 32: Loosen cap screws and check for end play in the system to assure the components are free.
Step 33: Torque cap screws, 10, to 48 Ib - ft (65.08 Nm). Rotate hub three revolutions. Torque cap screws to
96 Ib - ft (130.16 Nm). Rotate hub three revolutions. Torque the cap screws to 96 Ib - ft (130.16 Nm) and
rotate hub three more times.
Step 34: Through measuring hole provided in plate, 9, measure depth to axle. Average readings and
subtract thickness of plate to determine gap. Select shims from 11, 12, and 13 to equal gap plus
0.007 ± 0.001 in. (0.18 ± 0.03 mm).
Step 35: Install selected shims with plate, 9. Shims should be free of grease and dirt.
Step 36: Install three (3) washers, 14, and cap screws, 10. Torque all cap screws to 25 Ib - ft (33.9 Nm).
Rotate hub and torque to 100 Ib - ft (135.59 Nm). Rolling torque on hubs is to be 20 - 50 in - lb
(2.25 - 5.64 Nm).
Step 37: Lock cap screws, 10, with lockwire, 15. Route lockwire through screw heads. Twist the ends
together and cut off excess wire. Bend wire towards the inside.
Step 38: Clean grease and paint from machined surfaces on tandem case.
Step 39: Install both shaft and retainer assemblies to tandem case with fourteen (14) cap screws, 17, and
washers, 18.
Step 40: Torque cap screws to 95 ± 5 Ib - ft (128.8 ± 6.7 Nm).
