Specifications

1. Refer to the procedure for removing the left rear table top (with optional bobbin
winder assembly) and remove the table top.
2. Refer to Figure 2-18 and check the Y motor belt tension using the Melco force
gauge (p/n 995585-01) and the steps that follow:
3. Orient the Melco force gauge (p/n 995585-01) diagonally between the Y motor
belt and the top edge of power distribution section of the peripheral as shown
in Figure 2-18. The ’push end’ of the gauge should be toward the belt.
4. Place the finger of the ’push end’ of the gauge against the inside (toothed
surface) of the rear loop of the belt and mid-way between the pulleys centers.
The gauge plunger should be located just under the large Y shaft pulley when
positioned correctly. The other end of the force gauge plunger will be resting
against the top edge of front wall of the power distribution section.
5. Place a pencil mark on the plunger at the location where the inside surface of the
power distribution section wall touches the plunger.
6. Measure 0.2 inch toward the end of the plunger from the mark made in the
previous step and place another pencil mark on the plunger at that location.
