5. Belt tensioning
Figure 5: Tensioning Belt
Using the 1050 lever that you removed from your machine, tension the belt by prying against the
tensioning bolt and front of motor mount as shown in the illustration. A properly tensioned belt should
have about a ¼” of slack between the two sprockets. Tighten the two motor mount cap screws to maintain
the tension. Torque them to 15-18 ft lb (20-25 Nm).
WARNING
Belt must be properly tensioned for the drive to operate correctly and safely. Belt tension should be
checked periodically – when tensioned properly it should be tight with just a little flexibility from the
rubber material – you should be able to push down on the belt and it should feel firm.
