CHECKINGANDADJUSTING
REVERSEDRIVE BELTTENSION
Maintaining correct tension on the
reversedrive belt is important to good
performance and long belt life. A loose
belt will slip on the engine andtransmis-
sion pulleys and causethe tines and
wheels to slow down - or stop com-
pletely- eventhough the engine is
running at full speed. A loose belt can
also result in premature belt wear.
If there is no reverseaction when the
ReverseClutch Control knob is pulled
out, then the belttension is too loose.
When checking belt tension, also check
the belt for cracks, cuts or frayed edges
and replace it assoon as possible.
* Checkbelt tension after the first two
hours of break-in operation (new belt).
- Checkbelt tension after every 10
operating hours.
To CheckReverseBeltTension:
1. Be surethat the engine is stopped and
the spark plug wire is disconnectedand
moved awayfrom the spark plug.
2. Removethe screw in the plastic belt
cover and slide the cover (which is
attachedto the forward clutch cable) out
of the way.
3. Havean assistant pull the Reverse
Clutch Control knoball the way out and
hold it in that position. Measurethe
length of the cablewire betweenthe end
of the threaded cableadjuster (A, Figure
5-5) andthe end ofthe Z-fitting (B) to
which the cablewire is attached.
4. The belt tension is ideal if the cable
wire length measures between1/8" to
1/4". If the length is lessthan 1/8" (and if
there is no reverseaction when the tiller
is running), then makethe following
adjustments. NOTE:If the length is more
than 1/4", no adjustment is needed,as
long asthe reverseaction functions
properly.
5. Releasethe ReverseClutch Control
knob. Unthreadthe inner jam nut (C,
Figure5-6) oneto two turns and pull the
threaded cable adjuster (A, Figure5-6) to
the left until the inner jam nut rests
againstthe bracket.
6. Preventthe inner jam nut (C) from
turning and tighten the outer jam nut (D)
againstthe bracket. Preventthe outer
jam nut (D) from turning and tighten the
inner jam nut (C) against the bracket.
7. Measurethe gap by repeatingStep 3.

and 6.
8. Reinstall the belt cover.
