Replacing V-Belt
• Remove the belt keeper at the jackshaft
pulley for easier belt removal.
• Remove and replace the engine belt.
• If you have difficulty replacing the new belt,
you may need to relieve some of the tension
that was applied to the old belt. Read the
information on adjusting tension below and
loosen the belt tension.
• After replacing the V- belt, check the
tension. Engage the belt by sliding the
engine forward (reference engaged position
on previous page). The belt should deflect
3/8” with 25 lbs. of force applied to the
center of the belt between the sheaves.
New belts will stretch and become loose as
machine runs. Check and adjust belt tension
often when belts are new.
• If any adjustment is required, there is a
linkage assembly below the engagement
handle on the operator side. Loosen jam nut
and adjust clevis with wrench turning up
toward machine. This will make engine
slide further and will tighten the belt. Make
only slight adjustments at a time and
recheck tension; repeat as necessary until
tension is correct. Once proper tension is
achieved, tighten jam nut back onto clevis.
• Use this same procedure to tighten loose
belts.
• DO NOT OVER TIGHTEN BELT;
OVERLY TIGHT BELTS WILL CAUSE
BEARING AND ENGINE DAMAGE.
Turn the clevis in the opposite direction to
loosen belt 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.
