Replacing Poly Chain® Belt
• To tighten the belt more if needed, loosen the
front bolts and tighten each of the back jam
bolts the same number of revolutions, to keep
the alignment true. Make only slight
adjustments at a time and recheck tension;
repeat as necessary until tension is correct.
Then once the belt is adjusted, tighten the front
bolts against the bearing. Recheck belt
alignment after tightening all bolts and nuts to
make sure the belt is sill aligned.
• Use this same procedure to tighten loose belts.
• DO NOT OVER TIGHTEN BELT; OVERLY
TIGHT BELTS WILL CAUSE BEARING
AND ENGINE DAMAGE. To loosen the
tension on a belt, loosen the jam bolt and tighten
the bolt on the other side of the bearing.
Always make slight, equal adjustments on both
bearings and recheck tension.
• Replace belts when worn or when repeated
adjustments are necessary. Belts should never
get so loose that all of the adjustment capability
is used.
• Retighten the bolts in the jackshaft bearings
when the tension is adjusted properly.
• Retighten the bolts and nuts that are holding the
belt guard to the machine.
• Replace belt guard cover and bottom. Tighten
the bolts. DO NOT RUN MACHINE
WITHOUT ALL GUARDS IN PLACE AND
SECURED.
