Improper assembly of parts that are spring loaded can cause bodily injury.To prevent possible injury, follow the established assembly procedure and wear protective equipment.
Note: Check the O-ring seals for wear or for damage. If necessary, replace the O-ring seals.
Position fork (46) into the center housing. Install shaft (47) , spring (48) , bushing (49) , retaining ring (50) , O-ring seals (51) , piston (52) , O-ring seal (53) , and cover (54) . Apply Tooling (K) to the threads of bolts (55) and install bolts (55) . Install retaining ring (45) , washer (44) , spring (43) , O-ring seal (42) , and cover (41) . Apply Tooling (K) to the threads of bolts (40) and install bolts (40) . Tighten bolts (40) and (55) to a torque of 23 N m (17 lb in).

Install a dial type torque wrench onto the pinion shaft. Measure the total rotating torque. Use the following formula in order to calculate the total rotating torque (TRT): P equals the rotating torque that was measured in Step 14. TRT = P + 0.280 N m (2.48 lb in) to P + 0.467 N m (4.13 lb in)
If, the total rotating torque (TRT) is less than the specified amount tighten both spanner nuts equally. If the total rotating torque (TRT) is greater than the specified amount, loosen both spanner nuts equally. Always maintain slight backlash.

Typical example
Mount Tooling (M) onto the center housing. Measure the backlash between the pinion and the bevel gear. The proper backlash setting is 0.180 to 0.230 mm (0.0071 to 0.0091 inch).
Illustration 34 g01449257
If the backlash is not within the specification, retract one spanner nut and advance the opposite spanner nut equally order to maintain the bearing preload. If the backlash is less than the specified amount, move the bevel gear in Direction (A) . If the backlash is greater than the specified amount, move the bevel gear in Direction (B) .
