Belt Adjustment and Replacement

The idler pulley for the drive belt is positioned in
outside hole of idler control arm. If through wear
and stretch, adjustment becomes necessary, belt
tension can be increased by moving the idler
pulley to the center hole in idler control arm. The
PTO belt can be adjusted by loosening the three
capscrews that hold PTO support casting to axle
support casting. Raise or lower PTO support casting
to proper adjustment.
To Remove Drive Belt
The belt from engine to driveshaft can be replaced
in the same manner as changing speed range (see
page 7) but instead of moving belt to small groove,
free it completely from pulley. Next, slide belt
from opposite pulley and it is free.
To Remove PTO Belt
To remove PTO drive belt it is necessary to first
remove the belt from engine to driveshaft. Remove
belt guide from power-take-off pulley, and with
PTO disengaged, remove belt starting on the
lower pulley.
Generator-Starter Drive Belt Adjustment
The generator- starter drive belt can be adjusted by
loosening the capscrew on the adjustment bracket
and moving the generator-starter. The belt is prop-
erly adjusted when it can be depressed approx-
mately ¼ inch under slight thumb pressure.
Brake Adjustment (HUSKY 600)
The brake may require adjustment periodically
due to wear. Adjust at two points (1) To adjust
brake on transmission shaft (located under tractor
frame in line with brake pedal) adjust by moving
the two nuts on the top side of the pivot block.
(2) To adjust brake on drum loosen brake adjusting
nut on brake rod. Turn nuts at both points only
one or two turns at a time until proper brake
adjustment balance is obtained.
Brake Adjustment (HUSKY – 800 & 900)
The brake may require adjustment periodically
due to wear. Adjust by moving the nuts (D) on
both sides of the pivot block. Turn nuts only one or
two turns at a time to prevent over-adjusting the
brake. If brake is set too close there will not be
enough free clutch pedal travel making it difficult
to operate the tractor smoothly and shift properly.
