Check Attachment Idler Arm Roller
Clearance
1. Place the unit into the service position.
Remove the bottom cover.
2. With the attachment clutch lever
engaged, check the clearance between
the frame and plastic roller on the lower
end of the attachment idler arm.
•
If roller is 1/2 – 7/8" (12.7 – 22.2 mm)
from frame, no further adjustment is
needed.
•
If roller is more than 7/8" (22.2 mm)
from frame, loosen idler adjustment
nut and move idler away from the belt,
tighten adjustment nut and recheck
roller clearance.
•
If roller is less than 1/2" (12.7 mm)
from frame, loosen idler adjustment
nut and move idler closer to the belt,
tighten adjustment nut and recheck
roller clearance.
Check Attachment Brake
1. With the attachment clutch lever
disengaged, brake pad must contact
attachment belts. With clutch lever
engaged, brake pad must be more than
1/16" (1.6 mm) from belts. If there is
more than 1/16" (1.6 mm) gap, go to
page 30. If there is less than 1/16" (1.6
mm) gap, go to step 2.
2. If there is less than 1/16" (1.6 mm) gap
between brake pad and belts, loosen
idler adjustment nut and move idler
away from belt. Position idler to achieve
a 1/16" (1.6 mm) minimum brake pad
gap and a 1/2 – 7/8" (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
1. With attachment clutch lever engaged,
the belt finger located opposite the belt
idler must be less than 1/8" (3 mm) from
belts, but not touching the belts
(Figure 37).
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.
