6.9 V-Belts
Check and tighten the V-belts as required after 2 hours of operation. To tighten V-belts, adjust jam
nuts under engine mount. (
). The V-belts should be changed once they can no longer be
tightened to the correct tension, or when showing signs of excessive wear. Follow the steps in
to change the V-Belts. Recheck belt tension after 8 hours and every 40 hours thereafter.
Always replace both belts and inspect sheaves for wear.
CAUTION
Do not over-tighten belts as damage will occur to belts and bearings. Belts that are too loose will
shorten the life of the belts and sheaves. When installing new belts do not attempt to stretch over
sheaves.

Tighten belt tensioner. Correct tension is 1/4” deflection per belt when 10 lbs. pressure is
applied. Incorrect belt tension will cause poor belt life, damage to bearings, and engine
crankshaft bearing failure.
