V-Belts
V-belts stretch and wear with use, so check them
on a monthly basis to ensure optimal power
transmission. Replace all of the V-belts if any of
them show signs of glazing, fraying, or cracking.
Tools Needed: Qty
Phillips Screwdriver #2 ........................................ 1
Open End Wrench 24mm...................................... 1
To adjust the V-belts:
1. DISCONNECT LATHE FROM POWER!
2. Remove the cover shown in Figure 145.
4. Firmly tighten the hex nuts (loosened in the
previous step) against the motor mount plate
to prevent it from moving out of adjustment
during operation, then re-install the motor
cover.

3. Turn the hex nuts on the motor mount bolts
shown in Figure 146 to move the motor
mount plate up or down and adjust the
V-belt tension. When correctly tensioned,
each belt should have about
3 ⁄
4
" deflection
when pressed firmly (see Figure 146).
To ensure that the belts do an equal part
in transmitting power, always replace all of
them at the same time. If one belt is larger
or has more deflection than the others, the
other belts will absorb the additional load
and wear faster.
