21. Continue to maintain belt tension and separate the
beams slightly. Rotate the contact shaft to visually
ensure correct drive belt alignment.
22. Push the beams back together and rotate the beam
to a vertical position, which will provide some drive
belt tension.
23. Install and tighten the 1/4 in. (10) & the lower of
the 5/16 in. beam screws.
24. Start the upper 5/16 in. beam screw 2 turns.
25. From the front side of the grinder, position a lever
(a long screwdriver will work) on top of the head of
the 5/16 in. screw & underneath the rear of the
motor pivot, up against the inside beam. Adjust
the drive belt tension by applying force in the
appropriate direction and tightening the upper belt
tension nut.
26. Rotate the contact shaft by hand to ensure that the
drive belt is tensioned and aligned correctly. (Belt
tension can be verified by reaching into the cap
plug hole on the outside beam with your finger)
27. Re-tighten both drive belt tension nuts securely.
28. Tighten the remaining 5/16 in. beam screw.
29. Connect the power source and turn on the motor.
Check that there are no vibrations or rumbling in
order to verify correct assembly to this point.
30. Turn off the motor and remove the power source.
31. Install the cap plugs (2) into the outside beam.
32. Place the tension seal retainer (with tension knob
seal) and tension knob spring onto the tension
bushing. (Fig. 4)
