SP8018 SERVICE BELTS
ADJUST BELT TENSION
•
There are four engine slide bolts (3/4
”)
mounting the engine to the frame. There
are also two eyebolts for adjustment,
which are mounted to the two engine
slide bolts at the front of the machine to
move the engine and adjust the belt
tension.
•
Loosen all four of the engine slide bolts
enough to be able to move the engine but
don’t remove the bolts. The bolts are
secured through a block under the frame
and will require only one wrench to
loosen.
•
Loosen the inside jam nuts on the
adjustment eyebolts.
•
Turn the outside jam nuts clockwise,
moving the engine closer to the right
side of the machine and tightening the
belts. Make only slight adjustments at a
time and recheck tension. Make equal
adjustments to both eyebolts to keep
sheaves aligned. Keep making slight
adjustments and recheck tension until
correct tension is achieved.
•
To loosen belt tension, loosen the
outside jam nut and turn the inside jam
nut counter-clockwise making slight and
equal adjustments as with tightening the
belt tension.
•
Once belt tension is correct, first tighten
the two engine bolts (without eyebolts).
on the back side of the engine. Next
loosen all jam nuts, then tighten the two
front side engine bolts (with eyebolts).
Finally, re-tighten jam nuts.
•
Torque all four engine slide bolts to 230
ft lbs.
CAUTION
Do not over tighten belt; overly tight belts
will cause bearing and engine damage.
Replace belts when worn or when
repeated adjustments are necessary. Belts
should never get so loose that all the
adjustment capability is used.
