Adjustments
Use the following procedure to check and adjust
clutch disengagement and brake action:
Stop Block Eccentric Adjustment - Step 1
Use the stop block attached to PTO belt tightener
arm to set the bottom position of the clutch idler
pulley in the disengaged position. The stop block
should contact the chassis to stop the clutch idler
pulley from moving further down in the disengaged
position. If the stop block is not contacting the
chassis in the disengaged position, it will be nec-
essary to loosen the brake band adjustment nut.
The stop block is an “eccentric” block that will allow
four adjustment positions from 5/16 to 11/16 in.
(8 to 17 mm).

PTO Belt Tightener Stop Block Adjustments
Clutch Idler Pulley Travel Adjustment - Step 2
Adjust the stop block to give 1 to 1-1/2 in. (25 to
38 mm) pulley travel from “clutch engaged” to
“clutch disengaged”. To check and adjust the
pulley travel, rst engage the clutch, then measure
the distance the pulley moves down as the clutch
is disengaged and the stop block contacts the
frame.
NOTE: The importance of this adjustment is if the
pulley travel is excessive and the belt develops too
much slack, the belt will derail when disengaged.
