Check Attachment Brake

(Figure 33)

1.With the clutch lever disengaged, brake pad must contact attachment belt. With clutch lever engaged, brake pad must be more than 1/16 in. (1.6 mm) from belt. If there is more than 1/16 in. (1.6 mm) gap, go to Check Belt Finger Clearance on page 29. If there is less than 1/16 in. (1.6 mm) gap, go to Step 2.

2.If there is less than 1/16 in. (1.6 mm) gap between brake pad and belt, follow these steps:

a.To increase brake pad gap, loosen idler adjustment nut, and move idler away from belt. Position idler to achieve a 1/16 in. (1.6 mm) minimum brake pad gap and a 1/2 – 7/8 in. (12.7 –

22.2 mm) gap between the plastic roller and the frame.

IMPORTANT: If adjustments cannot be brought into specified ranges see your Dealer for repairs.

Check Belt Finger Clearance

(Figure 34)

1.With clutch lever engaged, the belt finger located opposite the belt idler must be less than 1/8 in. (3,2 mm) from belt, but not touching the belt.

To adjust belt finger, loosen the bolts and move the finger to the proper position. Tighten the bolts and recheck the belt finger clearance.

2.Replace the belt cover and tighten hardware.

Check belt finger clearance here. With the attachment clutch engaged, there should be less than 1/8 in. (3,2 mm) clearance between the belt and the belt finger. The belt finger should not touch the belt.
