V-Belts
V-belt removal and replacement is simply a matter of
adjusting the motor mount, rolling the belts off of the
pulleys and replacing them with new belts, then reten-
sioning them.
Always replace V-belts with a matched set of 3 belts, or
belt tension may be unven among the 3 belts and may
cause premature belt failure.
To adjust/replace the V-belts, do these steps:
1. DISCONNECT THE PLANER FROM POWER!
2. Remove the motor and front access panels and V-
belt cover.
3. Using a 19mm wrench, loosen the hex nuts on the
tension rods shown in Figure 15.
4. Lift the motor up and slide the V-belts off of the
pulleys.
5. Make sure the pulleys are in alignment as outlined in
Pulley Alignment on Page 37.
6. Slide the new belts onto the pulley, lower the
motor, and tighten the fasteners loosened in Step 3.
7. Check belt deflection as shown in Figure .
Note: The correct tension for the V-belts is 1⁄4"–1⁄2"
deflection when pushed in the center with moderate
pressure. After the first 16 hours of belt life, reten-
sion them, as they will stretch and seat during this
time.
8. Close the V-belt cover and replace the front and
motor access panels.
