1. V-belt tension bolt2.
Extension spring measurement3.
Front hanger cover
When belt slippage occurs or spring coils touch,
readjust to 1/16-inch spread. Under no condition
should the tension adjustment distance be allowed
to fall under 3-1/8-inches.
The main drive V -belt is adjusted for tension by
the V-belt tension bolt. Tighten the locknut to
increase belt tension and loosen the locknut to
decrease the belt tension.
NOTE: When installing a new belt always checkthe
condition of the pulleys and if they are not in
satisfactory condition, replace them with new
pulleys available at your I nternational Harvesterdealer.
When installing a new belt, the initial tension is
obtained by adjusting the bolt so the distance
measures approximately 3-1 /2-inches from the cen-
ter of the pulley (at the extension spring) to the
inner face of the front hanger cover.
To install or remove the belt, loosen the V-belt
tension bolt, raise the mower and disconnect the
power take-off clutch lever rod. NOTE: Refer to
the Front Power Take-off section of the Tractor
Operator's Manual. This will provide sufficient
clearance between the wear and thrust buttons on
the clutch to allow V-belt to pass through. Re-
adjust V-belt tension as previously described.
The main drive belt is properly tensioned when the
extension spring coils are spread approximately
1/16-inch.
NOTE: After the first half hour of mowing,
readjust bolt to the 3-1 /2-inch dimension.
