Grizzly G9860 Belts, Tools Needed Qty, To properly tension the V-belts, To replace the V-belts

V-Belts

V-belts will wear and stretch with extended use. Maintaining proper tension of V-belts and making sure they are in good condition will increase the efficiency of the cutterhead and reduce wear on the bearings.

When a V-belt can no longer be properly ten- sioned or is cracked/damaged, replace both V-belts as a matched set.
