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

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.
