Separator Drive Sheave Gap—Adjusting

IMPORTANT:

A - Cap Screws (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 low end of 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 low end of variable drive, check for incorrect gap. For best performance, set gap to specification.

Item	Measurement	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.

CAUTION: Shut OFF engine, set parking brake and remove key.

Loosen cap screws (A) around gearcase.

NOTE: Shift gearcase to neutral to properly seat belt between sheaves. Manually rotate sheaves, while adjusting turnbuckle.

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

Item	Measurement	Specification
Sheaves	Gap	8 mm (5/16 in.)

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

Shift gearcase to desired speed range.
