REMOVING THE PERF SHAFT
(Changing the position of the lower assemblies)
Turn the power off and unplug the machine. You may want to remove the upper assemblies
before you begin to get them out of the way as the rollers are spring loaded and will give
pressure on the lower rollers. Loosen the set screws on all of the lower assemblies. Loosen the
2 set screws on the bearing hub located on the inside of the operator side frame as shown
below.
Next, remove the non-operator side cover. DO NOT REMOVE ANY PULLEY'S! Loosen the
screws on the belt tensioned idler pulley (as shown below).
You do not need to remove the screws as loosening them will allow enough movement to remove
the belt. Remove the belt. Now remove the belt from the motor by turning the pulley by hand
and walking the belt off the pulley with no flanges on the perf shaft. Once removed there should
be no more belts on the perf shaft and the perf shaft should slide out easily. Slide the perf shaft
out the pulley side 6-8 inches the allow it to rest on the hole in the frame.
It is only necessary to slide the shaft out about 6 to 8 inches. With the shaft slid to the side, you
can access the lower hubs and reconfigure them as needed from under the front of the machine.
After you have configured the lower shaft, replace the shaft into its bearing and tighten the set
screws on the bearing hub. The shaft should be tight and not be able to move side to side. With
both drive belts back in position, re-tension the belt idler and tighten while applying constant firm
pressure on the belts by pushing down on the tops of the brackets with the large T-handle
wrench supplied. Replace cover. Align upper assemblies accordingly.
