CARE AND MAINTENANCE

HYDROSTAT DRIVE BELT TENSION ADJUSTMENT

In normal use the hydrostat drive belt tension should be check after the first 20 hours of
use for normal wear in and stretch. It may be adjusted as follows:

A.

Loosen the idler pulley locking nut until the idler pulley can be just moved relative to the
mounting bracket.

B.

Tighten the tension adjust bolt until the belt is tight enough to prevent belt slippage.
Belt should deflect approximately 3/8" to 5/8" under moderate pressure. Do not over
tighten.

NOTE: If belt is over tightened it will often make a "chattering" noise.

C.

Retighten the slide locking nut.

D.

Retighten the tension adjust bolt 1/4 turn to set the lockwasher and prevent loosening
of the tension adjust bolt.
