KVSP/TKVSP Owner’s Manual

BELT TENSION ADJUSTMENT

DO NOT ADJUST WHILE THE MACHINE IS RUNNING!

1.Wait for engine to cool and disconnect spark plug.

2.Remove the transmission cover

3.Using two ½” wrenches loosen the two nuts on the cable that connects to the idler arm.

4.The setting of the tension on the belt is controlled by the distance on the threads of the cable. To loosen tension, move the position towards the end of the threads and in the opposite direction to tighten.

5.Check the travel of the idler arm by engaging the bail, which the drive should start to engage when the bail is 2 ½ inches away from the handle. The spring, at a relaxed state should be 1.5 inches long on the coil, and when the bail is in contact with the handle it should be 1.75 inches long. If the belt is too tight it can cause premature failure and if it is too loose it can come off of the pulley.

6.When satisfied with the position, place the transmission cover back into place and secure. Then run the machine to make sure the transmission is engaging properly. If the drive will not engage or will not disengage repeat the previous steps.
