INSTALLING A REPLACEMENT V-BELT OR 
PULLEY 
Application: As Specified. 
Tools Required: 
1 each, 7/16 inch wrench. 
2 each, 1/2 inch wrenches. 
1 each, 9/16 inch wrench. 
1 each, 16 inch minimum length  straightedge. 
1 each, 10 lbs minimum capacity, tension scale or belt 
tension tool. 
1 each, torque wrench, 35 ft lbs (47 Nm.) capacity with 
7/16 inch and 9/16 inch sockets. 
 
Parts Required: 
1 each, PN 29020-056 V-belt 3VX335 (if required). 
1 each, PN 29020-038 bushing (if required). 
1 each, PN 29020-037 pulley (if required). 
1 each, 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. 
 
 

 

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. 
 
 

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.

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.
