of the brake stud and slide the brake stud in the slot. When the proper disengaged spring length
is achieved, tighten the bolt on the top of the brake stud. For this procedure do not adjust the
spring length. The spring length should only be changed when adjusting the belt tension.
Brake Stud Clearance:
This inspection is necessary to prevent over-braking. With the clutch engaged, check to make
sure that there is at least 1/2” of clearance between the brake stud and the belt. If the clearance
is less than 1/2” then it will be necessary to adjust the brake stud away from the belt. Keep in
mind that the disengaged spring length must stay between 3-1/4” and 4”.
CAUTION: If brake stud is not set in correct position, under-braking or over-braking may
occur. If over-braking occurs, premature belt failure or a possible fire could occur due to
excessive friction and overheating.
