Replacing the Drive Belt: CMC Z1, Z (9000z), 9000, 8500e SBT, 8500e, 8500 and 8000

  • The drive belt has been damaged and needs to be replaced.

Note: In order to preserve alignment, the drive belts must be replaced in pairs. If you did not receive a pair of drive belts for replacement, please contact Wizard customer service. Your hardware might look slightly different than that pictured but the pieces perform the same functions.

Part #:

30-99000-2 Belt Assembly Kit - Rev2

Tools

  • Strip of matboard about ⅜” (9mm) wide and 7” (18cm) long, to help install the new belt.

  • Set of Allen wrenches

Removing the Drive Belt

  • Remove the cover from the gantry by unscrewing the screws that hold it in place and set aside.

  • Remove the 5/32” Allen screws and washers from the lower gantry plate.

  • These were placed here to assist in loosening the belt tensioner.

  • Look for Red Dots (only these screws are to be adjusted).

  • Locate the 3/16” Allen belt tensioner screw that’s located on the right bottom side of the lower rail and marked with a red dot.

WARNING: Do not over-loosen this screw - one full turn is usually sufficient.

  • Loosen this screw one turn only so that there is some movement in the belt tensioner.

  • The tensioner springs should be visible.

  • Locate the belt tensioner hole on the end of the belt tensioner.

  • Place the 5/32” Allen screw and washer we removed from the lower gantry plate into the belt tensioner hole.

  • Tighten the Allen screw until belt tensioner is flush with the rail and the springs are not visible.

  • Go back and tighten the 3/16” Allen belt tensioner screw on the right bottom side of the lower rail marked with a red dot.

  • Lift the drive belt end out of the belt tensioner slot.

  • Pushing the drive belt end to the right may assist in getting a hold of it.

  • Repeat the last six steps with the upper rail.

  • Move the gantry to the left to loosen the slack and free the belt anchor from the end of the rail.

  • Unscrew the 1/8” Allen screw on the clamp that holds the belt to the belt anchor and remove the belt end from it.

  • Work the drive belt back through the gantry wheels and remove it from the gantry.

  • Remove the drive belt with the drive end still in place.
