1. Stopengine, allow it to cool and dis-
connectspark plug wire beforeworking
near belts. Also remove ignition keyon
electricstart models.
IMPORTANT:Theforward clutch belt
must be installed beforethe reverse
clutch belt.
The reverseclutch belt (J, Figure5-22) is
driven by the enginedrive pulley (I, Figure
5-20). Whenthe ReverseClutchControl
knobis pulled out, it pulls the reverse
idler arm and pulley (N) which tightens
the belt againstthe engine drive pulley.
This drivesthe transmission drive pulley
(L), resulting in reversemotion.
RemovingReverseClutchBelt
1. Stop engine,allow it to cool and dis-
connect spark plug wire beforeworking
nearbelts. Also remove ignition key on
electric start models.
2. Remove beltcover (Figure5-13) by
removingtwo flange Iocknuts.
3. Pull the reverseclutch belt downward
2. Install the forward clutch belt (see
Installing Forward Clutch Beltin this
section) before installing reversebelt.
IMPORTANT:The reversebelt has a 'V"
shape. When installing the belt, make
surethat the widest (flat) side of the belt
rides againstthe reverseidler pulley (N,
Figure5-22) andtransmission pulley (L).
If needed,the belt can be twisted "inside
out" sothat the "V" shaped side ison the
outside and the widest side is on the
inside.
3. Insert the belt down into the front of
the transmission housing. Slipthe top
