Tensioning/Replacing V-Belts - Grizzly G0834 Owner's Manual

Tensioning/
Replacing V-Belts
V-belts transfer power from motor to cutterhead.
To ensure efficient transfer of power to cutterhead,
make sure V-belts are always properly tensioned
and in good condition.
After approximately 16 hours of opera-
tion, V-belts will stretch and seat into pul-
ley grooves. The V-belts need to be re-
tensioned after this initial break-in peri-
od to ensure optimum power transfer and
maximum overall life of the V-belts.
If the V-belts are worn, cracked, or damaged,
replace them. Always replace the V-belts with
a matched set, or belt tension may not be even
among both belts, resulting in sub-optimal power
transfer and premature belt failure.

3. Check belt tension: Each belt is correctly
tensioned when there is approximately
deflection when it is pushed with moderate
pressure, as shown in Figure 40.
