V-Belt Replacement
Inspect the V-belt closely; if you notice fraying, cracking,
glazing, or any other damage, replace the belt. A worn or
damaged V-belt will not provide optimum power transmis
-
sion from the motor to the cutterhead.
Overly loose V-belts can slip on the pulleys and burn up
or cause poor machine performance. Overly tight V-belts
cause unecessary wear on the motor and pully bearings,
leading to a shortened lifespan.
To replace the V-belts, do these steps:
1. DISCONNECT JOINTER FROM POWER SOURCE!
2. Open the back cover.
3. Loosen the motor bracket bolts shown by the black
arrows in
Figure 64.
4. Roll off the old V-belt and roll on the new V-belt, as
shown in
Figure 65.
5. Check the alignment of the pulleys to make sure the
V-belt is straight up and down.
— If the pulleys are aligned, skip to Step 9
.
— If the pulleys are NOT aligned, refer to
Pully
Alignment on Page 39 and align the pulleys.
6. Pull down on the motor with one hand to keep ten-
sion on the V-belt, and tighten the motor bracket
bolts with your other hand.
7. Push the center of the V-belt as illustrated in Figure
66, using moderate force. When tensioned correctly,
the deflection should be approximately
1
⁄4".
— If the deflection is not correct, loosen the motor
bracket bolts and repeat Steps 9–10
.
8. Reinstall the belt guard.
9. Replace the cover on the back of the jointer stand.
