TRACTION DRIVE BELT REPLACEMENT (Figure 37) NOTE: Replacement will be easier with housing and frame tipped apart and bottom cover off. 1. Remove attachment drive belts (see Attachment Drive Belts Replacement on page 30). 2.

REPLACEMENT
(Figure 37)
NOTE:
Replacement will be easier with
housing and frame tipped apart and bottom
cover off.
1. Remove attachment drive belts (see
Attachment Drive Belts Replacement
on
page 30).
2. To gain belt clearance, back out the stop
bolt from the frame until the drive plate
assembly can swing past it (Figure 38).
3. Pull idler away from traction drive belt
and remove belt from idler pulley, engine
sheave and driven pulley (it may be
necessary to turn engine pulley using
recoil handle).
4. Install new traction drive belt onto
attachment pulley and engine sheaves.
5. Pull the drive plate assembly toward the
friction disc and tighten the stop bolt.
NOTE:
Make sure the drive plate assembly
return spring remains connected to the frame.
6. Replace attachment drive belts
(
Attachment Drive Belts Replacement
on page 30
).
FRICTION DISC REPLACEMENT
(Figure 38)
1. Place unit into service position.
2. Remove bottom cover by removing six
hex bolts.
3. With axle locked, hold one wheel so
friction disc will not rotate and remove
three cap screws holding friction disc to
carrier.
4. Remove both wheels.
5. Remove right and left bearing flanges
from frame.
6. Slide hex shaft to the left enough to
remove pinion sprocket from hex shaft.
7. Slide hex shaft to the right enough to
remove friction disc.
8. Slide new friction disc onto hex shaft.
9. Install pinion sprocket and chain on hex
shaft, then replace bearing flanges.
10. Hold wheel so friction disc will not rotate
and secure new friction disc to carrier
with three hex screws removed in
step 2.
