Installing a Replacement V-BELT or Pulley

ASSEMBLY INSTRUCTIONS/OPERATIONS

4)Using the 1/2 inch wrenches, loosen the engine/electric motor attachment capscrews, and slide the engine/electric motor toward the front of the main frame. FIGURE 34.

INSTALLING A REPLACEMENT V-BELT OR

PULLEY

Application: As Specified.

Tools Required:

1each, 7/16 inch wrench.

2each, 1/2 inch wrenches.

1each, 9/16 inch wrench.

1each, 16 inch minimum length straightedge.

1each, 10 lbs minimum capacity, tension scale or belt tension tool.

1each, torque wrench, 35 ft lbs (47 Nm.) capacity with 7/16 inch and 9/16 inch sockets.

Parts Required:

1each, PN 29020-056 V-belt 3VX335 (if required).

1each, PN 29020-038 bushing (if required).

1each, PN 29020-037 pulley (if required).

1each, PN 10057-016 key (if required).

1) If the Floor Planer is powered by an engine, disconnect the spark plug wire. If powered by an electric motor, disconnect the extension cord or Floor Planer from the power source.

2)Position the Floor Planer on a suitable work surface with the V-belt approximately at waist level.

3)Using the 9/16 inch wrench, remove the belt guard from the main frame. Clean the inside of the belt guard with an appropriate solvent. Check for signs of wear and damage.

CAUTION

Observe all applicable safety precautions for the solvent.

3)Using a 1/2 inch wrench, remove the self locking nuts on the engine/electric motor take-up capscrews. Rotate the take-up capscrews until the hexagon head contacts the threaded mounting plate.

5)Remove the worn belt and install the replacement V-belt, PN 29020-056 (3VX335).

a) Do not install a replacement belt if the pulleys have worn grooves. Such pulleys should be replaced to insure proper belt fit. Operating the V-belt in worn pulley grooves will accelerate V-belt wear and significantly reduce its service life.

b)A V-belt should never be forced over a pulley. More belts are broken from this cause than from actual failure in service.

c)Keep the belt as clean and free of foreign material as possible. Do not use belt dressing.

6)Reinstall the engine/electric motor take-up capscrews with the heads facing toward and in contact with the engine crankcase/electric motor thrust plate. Tighten the engine/electric motor attachment capscrews until they just begin to apply tension to the engine/electric motor. DO NOT OVER TIGHTEN. Alternately tighten the take-up capscrews until slight tension is applied to the V-belt.

7)The driveshaft pulley should be positioned within 1/16 inch if the shaft shoulder. If the distance exceeds this limit, proceed as follows:

a) Using the 7/16 inch wrench, remove the two 1/4 inch diameter capscrews from the bushing.

b)Insert the capscrews into the tapped holes in the bushing flange. Tighten progressively until the bushing disengages from the pulley.

c)Insert the 1/4 inch diameter capscrews into the tapped holes in the pulley. Tighten progressively until the bushing applies tension to the pulley. FIGURE 35.
