1. V-belt tension bolt2.
Extension spring measurement3. Front hanger cover
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.
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.
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.
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.
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 Harvesterdeal
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.
