Separator Drive Sheave Gap—Adjusting

A - Cap Screw (4 used)

B - Nut

C - Turnbuckle

• Belt stretch or failure
• Bearing or shaft failure

If gap is less than 6 mm (1/4 in), it limits torque sensing. Any of these failures can occur when drive is operated at the low end of the variable range:

• Belt failure
• Belt slippage

If unable to obtain high speed while operating at high end of variable drive range or belt slippage occurs while operating at the low end of the variable drive, check for incorrect gap. For best performance, set gap to specification.

Sheaves	Gap	8 mm ± 2 mm (5/16 in ± 1/16 in)

With separator engaged, set separator drive to slowest speed allowing driven sheaves to close.

Shut OFF engine, set park brake and remove key.

Loosen cap screws (A) around gear case.

Shift gear case to neutral to properly seat belt between sheaves. Manually rotate sheaves, while adjusting turnbuckle.

Loosen nut (B) and adjust the turnbuckle (C) to obtain the specified gap between the driven sheaves.

Sheaves	Gap	8 mm (5/16 in)

Tighten nut (B) and cap screws (A).

Shift gear case to desired speed range.
