6-2-3 Belt Replacement

Important!

It is very important to replace all belts at the same time.

If the drive belts have to be replaced, follow the procedure in Section 6-2-1up to Step 6. Then release the belt from tension by fully unscrewing the tie rods. Slip off the belts, and replace them with new ones. Continue with the procedure for adjusting the belt tension.

∗The Deflection Force Value shown is for each belt and must be multiplied by the number of V-belt elements if all are deflected.
