Adjusting Single Tine Separator Drive Sheave Gap

IMPORTANT: If sheave gap is more than 10 mm (3/8 in.), it limits sheave travel. Any of these failures can occur when drive is operated at the high end of the variable drive range:

Belt failure

Belt stretch

Bearing failure

Shaft failure

If sheave 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:

Specification

If you are unable to obtain high speed rpm while operating in the high end of the variable drive range or have belt slippage while operating in the low end of variable drive, check for incorrect gap between the driven sheaves. An 8 mm (5/16 in.) gap should be maintained between sheaves for best performance.

Specification

To adjust the sheave gap:

With the separator engaged and running, set the tine separator drive in the low speed so the driven sheaves on the gear case are closed.

CAUTION: Shut off engine, set park brake and remove key.

Loosen four cap screws (A) holding gear case.

Adjust draw bolt (B) to the specified gap between the driven sheaves (use an 8 mm or 5/16 in. drill bit to measure gap).

Specification

Retighten cap screws (A).
