(1) Torque for seven bolts ... 68 ± 7 N·m (50 ± 5 lb ft)

(2) Assemble the ring with the side of the wedge downward onto the face of the commutator, as shown.

(3) Lubricate bores with a thin covering of lubricant that is being sealed.

(5) If your machine is equipped with 6G-1541 Pinion Drive Shaft , then 0S-1585 Bolt (1/2 inch) are used.

Torque for three 0S-1585 Bolt (1/2 inch) ... 130 ± 7 N·m (96 ± 5 lb ft)

(5) If your machine is equipped with 307-1965 Pinion Drive Shaft , then 6V-5686 Bolt (M16) are used.

Initial torque for three 6V-5686 Bolt (M16) ... 120 ± 20 N·m (90 ± 15 lb ft)
Final torque for three 6V-5686 Bolt (M16) ... 240 ± 40 N·m (175 ± 30 lb ft)

(6) Torque for four bolts ... 650 ± 25 N·m (480 ± 15 lb ft)

(7) Torque for nut ... 325 ± 27 N·m (240 ± 20 lb ft)

(8) Lubricate the bearing area of the shaft with a thin covering of the lubricant that is being sealed.

(9) All surfaces that contact the rubber toric rings and the actual rings must be cleaned and dry at assembly. Also, apply a thin film of oil to the contacting surfaces of the seals.

(10) Torque for four locknuts ... 650 ± 25 N·m (480 ± 15 lb ft)

(11) Thickness of shim ... 0.13 mm (0.005 inch)

(12) Thickness of shim ... 0.25 mm (0.010 inch)

As required, use shims (11) and (12) to obtain preload on the bearings (4) . Bearing preload is 0.065 ± 0.05 mm (0.0025 ± 0.002 inch).

(13) 6Y-7953 Friction Disc

Total quantity ... 11
Thickness of one new friction disc ... 2.87 ± 0.08 mm (0.113 ± 0.003 inch)
Minimum reusable thickness (total) ... 2.44 mm (0.096 inch)
Minimum reusable thickness (one side of friction material) ... 0.20 mm (0.0079 inch)

(14) Plate

Total quantity ... 10
Thickness of one plate ... 1.52 ± 0.13 mm (0.060 ± 0.005 inch)

(15) Disc spring

Assembled height ... 10.63 mm (0.419 inch)
Load at assembled height ... 98490 ± 19700 N (22130 ± 4430 lb)
Free height after load ... 12.94 mm (0.509 inch)
Outside diameter ... 150.11 ± 0.25 mm (5.910 ± 0.010 inch)

(18) Thickness of shim ... 0.13 mm (0.005 inch)

(19) Thickness of shim ... 0.25 mm (0.010 inch)

As required, use shims (18) and (19) on the initial assembly in order to achieve the proper deflection of disc spring (15) . The deflection of the spring should be 2.54 ± 0.25 mm (0.100 ± 0.009 inch).
