Check Attachment Idler Arm Roller
Clearance
(Figure 29)
NOTE: It will be difficult to check the
measurement inside the frame. Use a 1/2"
(12.7 mm) minimum spacer as a gauge to
check the clearance between the roller and
the frame.
1. Place the unit into the service position.
Remove the bottom cover.
2. With the clutch lever engaged, check the
clearance between the frame and plastic
roller on the lower end of the attachment
idler arm (Figure 29).
• If roller is 1/2 – 7/8" (12.7 – 22.2 mm)
from frame, no further adjustments
are required.
• 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
the roller clearance.
• 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.
