TORQUE WRENCH CHECK

When the left or right cover has been removed and maintenance work has been performed in either cover of the

left or right brakes, a torque wrench check must be performed. This check will indicate if an assembly error exists,

such as omission of a spacer or gear, or binding of parts.

The torque wrench check is performed after assembly of the transmission has been completed. The transmission

must be on the work table or on the f oor in the normal upright operating position. Refer to Figure 1 for an

illustration of the process.

This check is performed on a dry transmission (i.e., a transmission not f lled with oil).

NOTE

The torque wrench check provides an accurate method to check brakes.

When a brake is adjusted properly, 40 lb-ft (54 N·m) applied to the torque wrench, on the brake

apply shaft, should cause the indicator to line up opposite the APPLY mark.

1. Use torque wrench and socket wrench to turn left brake apply shaft counterclockwise until torque wrench

reads 40 lb-ft (54 N·m) and hold it there.

2. Check position of indicator in relation to the APPLY mark. Adjust brake if indicator does not line up opposite

APPLY mark. (Refer to WP 0065.)

3. Use torque wrench and socket wrench to turn right brake apply shaft clockwise until torque wrench reads 40

lb-ft (54 N·m) and hold it there.
