Adjusting the Timing Belt Tension
Check the timing belt for tautness by holding the transmission pulley and rocking the hand wheel. You
should not be able to feel play between the belt teeth and the transmission timing pulley teeth.
NOTE:
if you tighten the belt too much you will create a bind or extra noise in the machine. If a correction is
necessary:
•
Loosen the idler pulley screw and locknut – the bracket has an elongated hole in the motor
hosing for idler adjustment.
(5mm Allen tool and 10mm wrench)
•
Adjust the idler pulley in or out until the timing belt has the proper tautness.
