CHECKINGANDADJUSTING
REVERSEDRIVEBELTTENSION
Maintaining correct tension on the
reversedrive belt is important to good
performanceand long belt life. A loose
belt will slip on the engine andtransmis-
sion pulleys and causethe tines and
wheelsto slow down- or stop com-
pletely- eventhough the engine is
running atfull speed. A loosebelt can
also result in premature beltwear.
If there is no reverseaction whenthe
ReverseClutch Control knob is pulled
out, then the belt tension istoo loose.
Whenchecking belttension, also check
the beltfor cracks, cuts or frayed edges
and replaceit assoon as possible.
• Checkbelttension after the first two
hours of break-in operation (new belt).
• Checkbelttension after every 10
operating hours.
ToCheckReverseBeltTension:
1. Besure that the engineis stopped and
the spark plug wire is disconnectedand
moved awayfrom thespark plug.
2. Removethe screw in the plasticbelt
cover and slidethe cover (which is
attachedto theforward clutch cable)out
of the way.
3. Havean assistant pull the Reverse
Clutch Control knob all theway out and
hold it in that position. Measurethe
length of the cablewire betweenthe end
of the threadedcableadjuster (A, Figure
5-5) and the end of theZ-fitting (B) to
which the cablewire isattached.
4. The belttension is ideal if the cable
wire length measuresbetween1/8" 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 lengthis more
than 1/4", no adjustment is needed,as
long asthe reverseactionfunctions
properly.
5. Releasethe ReverseClutchControl
knob. Unthreadthe inner jam nut (C,
Figure5-6) one to two turns and pull the
threadedcableadjuster (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
