the High speed groove of the engine
drive pulley (the groove closest to
the engine) and in the middle groove
i_ the tr_.nsmission pulley. Be sure
the belt is to the insideof the wire
formed belt guide (I, Figure 4-13) and
to the inside of the forward drive idler
pulley (J).

• The belt tension is correct if the
guide mark (M, Figure 4-15) is any-
where to the left of the guide pin
(O), as viewed from the front of the
unit (not the operator'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.
3. The reverse idler pulley (L, Figure
4-14) 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 4-
14) off the engine driven reverse
(upper) pulley.
6. On the right side of the unit (as
viewed from operator's position) re-
move the hairpin cotter from the cle-
vis pin (R, Figure 4-14) that connects
the reverse idler arm (K) to the re-
verse adjustable link. Push inward
on the reverse idler arm (K) and re-
move the clevis pin (R).

verseDriveBelt
1. Remove the belt cover after first
shutting off the engine, disconnect-
ing 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 re-
verse idler arm (K, Figure 4-14) in-
ward as far as possible (the reverse
idler pulley [L] is attached to the re-
verse idler arm). Hold the idler arm
in this position and look at the posi-
tion of the belt tension guide mark
(M, Figure 4-15) that is stamped into
the face of the reverse adjustable
link (N, Figure 4-15).
