CHECKINGAND ADJUSTING
FORWARDDRIVE BELTTENSION
Maintaining correct tension on the
forward drive belt is important to good
tilling performance and long belt life. A
loose belt will slip on the engine and
transmission pulleys and cause the tines
and wheels to slow down - or stop com-
pletely - even though the engine is
running at full speed. A loose belt can
also result in premature belt wear.
If you find you can not bring the Forward
Clutch Bail all the way up to the bottom of
the upper handlebars,you will need to
loosen the belt tension.
Also check the belt for cracks, cuts or
frayed edges and replaceit as soon as
possible.
• Checkbelt tension after the first two
hours of initial operation (new belt).
• Checkbelt tension after every 10
operating hours.
To CheckForwardBelt Tension:
1. Be sure that the engine is stopped and
the spark plug wire is disconnected and
moved away from the spark plug.
2. Loosen nut "C" (Figure 5-4) several
turns so it is about halfway up the
threaded adjustment screw.
3. Lift the Forward Clutch Bail up and
hold it to the bottom of the handlebars.
Measure the length of the clutch bail
spring (A, Figure 5-4) with a ruler. If the
belt tension is correct, the length of the
coiled portion of the spring should be
approximately 1-7/8". Nut "C" should
then be snugged down against the top of
the adjuster (B).
4. If the spring is too short, the belt
tension will be too loose. If the spring is
too long, the belt tension will be too tight.
5. To adjust the length of the spring,
releasethe Forward Clutch Bail. Thread
the hex nut (C, Fig. 5-4) halfway up the
adjustment screw. Turn the screw inside
the spring (A, Figure 5-4) counterclock-
wise (as viewed from the operator's
position) while holding the adjuster (B)
steadyto increase the length of the
spring, or turn clockwise (as viewed from
the operator's position) to decreasethe
length of the spring.
NOTE:If you have difficulty holding the
adjuster steady by hand, use a pliers or
wrench on the adjuster. While you turn
the screw, keepthe Forward Clutch Cable
