Grizzly G0550/G0551 instruction manual Belts

V-Belts

To ensure optimum power transmission from the motor to the blade, the V-belts must be in good condition (free from cracks, fraying and wear). Check the V-belts at least every 3 months; more often if the planer is used daily.

Make sure that the motor pulley and cutterhead pulley are aligned and the V-Belts are properly tensioned.

To align the V-Belt:

1.Disconnect the machine from the power source!

2.Remove the V-Belt cover.

3. Loosen the bolts that mount the motor to the motor mount bracket.

4.Adjust the position of the motor until the pul- leys are in line, and check the alignment with a straightedge as shown in Figure 19.

Squeeze the V-Belts at their midpoints with mod- erate finger pressure. You should be able to deflect each V-Belt about 3/4". Belts will rarely be too tight, but will sometimes be too loose.

To tension the V-Belt:

1.Disconnect the machine from the power source!

2.Insert a wooden lever between the motor mount and the top of the planer as shown in Figure 20.

Loosen These Bolts

3. Loosen the two bolts that hold the motor pul- ley assembly to the planer (Figure 19).

4.Lift the motor assembly with the wooden lever until the belt is tensioned correctly.

5.Hold the motor in place and secure the bolts loosened in step 3.

6.Squeeze the belts to check the tension and repeat steps 2-5if necessary.
