Y-Axis Timing Belt Tensioning
The Y-axis timing belt tensioning requires that the machine is turned
off while measuring the tensions. This procedure can be performed
by the machine operator as long as the following procedures are
followed explicitly.
This procedure requires the use of a 0-10 lb. Force Gauge, a Universal
Force Gauge Adapter, Y-Belt Tensioning Fixture, a 3mm Hex wrench,
and a 7mm nut driver.
•
CAUTION!! DO NOT over tension timing belts. If you do, the belts will stretch excessively and
might cause heavy internal damage to the machine.
Y-Axis Belt Tension Inspection
1. Attach the Universal Force Gauge Adapter, PN 32498, to the 0-10 lb. Force Gauge, PN 995591-01
(screw adapter on the end of the gauge).
2. Remove the left and right covers (use 3mm hex wrench to remove screws).
3. Move the x-beam all the way to the front of the machine until it comes to a dead stop.

4. Center the Y-belt tensioning xture on top of the lower y-belt (see Figure 2).
