The brake stud may need to be adjusted if there is significant belt wear or if a
different size belt is used. If the brake stud is not adjusted correctly, the blades will
still spin even though the clutch may be in the disengaged position. Always shut
mower engine off before servicing.
Under normal operating conditions and when using the Kunz Engineering belt (Part # 238007) the
brake stud should require very little adjustment. Periodic brake stud inspections should be
performed every 10 hours. In more severe cutting conditions, more frequent inspections may be
necessary. There are two parts to inspecting the brake stud. Those two inspections are the
disengaged spring length and brake stud clearance.
Note: It is quicker to perform the disengaged spring length and brake stud clearance
inspections if done simultaneously.
Disengaged Spring Length:
This inspection must be performed to make sure that there is proper braking force to prevent the
blades from spinning when the clutch is in the disengaged position. With the clutch in the
disengaged position measure the spring length. The spring must be between 3-
1/4” and 4” to
provide the appropriate braking force
. If the spring length is over 4” it w
ill be necessary to adjust
the brake stud closer to the belt. If the spring length is less than 3-
1/4” it will be necessary to
adjust the brake stud further away from the belt. To make brake stud adjustments loosen the bolt
on the top 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. To inspect the brake stud clearence it is
easiest to remove the left belt sheild and observe from the left side. With the clutch engaged,
check to make sure that ther
e 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 stu
d away from the
belt. Keep in mind that the disengaged spring length must stay between 3-
1/4” and 4”.
Note: If the brake stud is adjusted to the end of the slot and the brake stud clearance is under
1/2” the
n it is time to replace the belt.
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.
