WARNING
Before inspecting, cleaning or servicing the unit, shut off engine, wait for all
parts to come to a complete stop, disconnect spark plug wire and move wire away from spark
plug.
Failure to follow these instructions can result in serious personal injury or
property damage.
8. Replace the forward drive belt in the
Low (or High) speed grooves of the
engine drive pulley and the transmission
pulley. Be sure the belt is to the inside of
the wire formed belt guide (I, Figure 5-12)
and to the inside of the forward drive idler
pulley (J).

Reinstall the belt cover and secure it
with the two nuts.
10. Readjust the forward drive belt
tension by following the instructions
in "Handlebar Height Adjustment" on
Page 12.

hole in forward adjustable link and move to
inner hole in link.

To Check and Adjust Tension on the
Reverse Drive Belt:
1. Remove the belt cover after first shut¬
ting off the engine, disconnecting the
spark plug wire, and allowing the engine
and muffler to cool down.
2. Stand at the front of the tiller and use
your left hand to push the reverse idler
arm (K, Figure 5-13) inward as far as pos¬
sible (the reverse idler pulley [L] is
attached to the reverse idler arm). Hold
the idler arm in this position and look at
the position of the belt tension guide
mark (M, Figure 5-14) that is stamped
into the face of the reverse adjustable link
(N, Figure 5-14).
• The belt tension is correct if the guide
mark (M, Figure 5-14) is anywhere to
the left of the guide pin (0), as viewed
from the front of the unit (not the opera¬
tor's position). If the belt tension is
correct, reinstall the belt cover and
secure it with
the two nuts.
• If the guide mark is aligned with the
guide pin, or moves to the right side of
the guide pin, then the belt is too loose
and the tension must be readjusted as
described next.

reverse pulley (L).
Figure 5-14: While pushing reverse idler arm
inward, stand at engine end and check posi¬
tion of guide mark (M) and guide pin (0).
3. The reverse idler pulley (L, Figure 5-13)
regulates the tension that is applied to the
reverse drive belt (P). The following
adjustment will allow the reverse idler
pulley to apply more tension to a loose
belt.
4
.
Remove the belt cover.
5. Slip the reverse belt (P, Figure 5-13)
off the engine driven reverse (upper)
pulley.
6.
On the
right
side of the unit (as viewed
from operator's position) remove the
hairpin cotter from the clevis pin (R,
Figure 5-13) that connects the reverse
idler arm (K) to the reverse adjustable
link. Push inward on the reverse idler
arm (K) and remove the clevis pin (R).
