NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
Note: Cleanliness is an important factor. Before assembly, thoroughly clean all parts in cleaning fluid. Allow the parts to air dry. Do not use wiping cloths or rags to dry parts. Lint may be deposited on the parts which may cause trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. Dirt and other contaminants can damage the precision component. Perform assembly procedures on a clean work surface. Keep components covered and protected at all times.
Note: Check the O-ring seals and the seals for wear or for damage. Replace the components, if necessary.

Illustration 30 g01641805
35. Install a dial type torque wrench onto pinion shaft (46). Measure the total rotating torque. Use the following formula to calculate the total rotating torque (TRT): P equals the rotating torque that was measured in Step 14. TRT = P + 0.519 N·m (4.593 lb in) to P + 0.778 N·m (6.885 lb in)
36. 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. Be sure to always maintain slight backlash.
37. Use a suitable hammer and a punch to stake nut (32).
Illustration 31 g01641806
Typical example 38. Mount Tooling (L) onto the center housing. Measure the backlash between the pinion and the bevel gear. The proper backlash setting is 0.18 to 0.32 mm (0.007 to 0.013 inch).
Illustration 32 g01449257
39. If the backlash is not within the specification, retract one spanner nut and advance the opposite spanner nut equally. This will 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).
Illustration 33 g01641796
40. Install retainer (19) and bolt (20) into both brake cylinder assemblies (11). Tighten bolts (20) to a torque of 13 N·m (10 lb ft). Repeat this step for the opposite side.
Illustration 34 g01641808
41. Apply Tooling (J) to the threads of bolts (40). Position brake assembly (39) and install bolts (40).
Illustration 35 g01636808
