General Belt-Fix Kit Instructions for 12 or 15 pin belts.

  • Use these instructions if your belt has intermediate rollers. (These would appear between the drive pins and have a flat portion on top where they are molded onto the belt.)
  • When belts have intermediate rollers, it is necessary to align the drive pins on both tractors alike. (It is possible to assemble the Belt-Fix Kit onto the tractors and not have the corresponding pins aligned. However, in this case, the holes in the form would not line-up with the tractor pins and loading would be difficult or impossible.)
  • Follow the basic Belt-Fix Kit instructions, bearing in mind that the belt must be fitted into the drive sprocket identically matching the tractor adjacent to it. (Align a pin directly over the drive sprocket of the other tractor and repeat the alignment on the belt being replaced prior to bonding the belt together.)

Repair or Replace?

Tractors with metal needle bearings will rarely need to be replaced. However, tractors with plastic bearings should be inspected for replacement. Clearances of more than 0.010" (twice the thickness of the belt,) will greatly reduce the life of the new belt, as well as affect the registration quality of the drive system, and consequently, the quality of your print jobs. Replacing the entire assembly is advised.

1. Remove broken belt and clean debris from the tractor with a stiff bristle brush.

2. Feed the belt around its track on the tractor. Start at top with hole end of belt.
3. Apply a small dot of glue on the pin end of belt. See instructions.

4. Press belt over pin through hole in belt. Hold in place for 10 seconds.

Caution: Read manufacturer's warning before using Loctite 495 adhesive. Avoid any contact with hands. Use a pencil or other device to press belt ends together during bonding.
5. If a belt tensioner is used on the assembly, loosen the tensioner screw 1 turn and then retighten. 3
