Carriage Belt Tension

2.1 Carriage Belt Tension

Tools Needed

• 7/16 Ratchet Wrench
• Gates Belt Tension Meter or equivalent

(1) Loosen the two hex head bolts using a 7/16 ratchet wrench. The two hex bolts will be located on the far right underneath the belt pulley. See photo 2.1-1

(2) You can now adjust the belt tension by tightening or loosening the nut on the threaded rod. Use a 7/16 ratchet wrench to loosen and tighten the belt. See Photo 2.1-2

(3) Once you have adjusted the tension, check the belt using a Gates belt tension meter or equivalent. Below are the belt specifications for the meter.

Mass (M) - 001.4 g/mm
With (W) - 009.0 mm/r
Span (S) - 0800 mm

The belt tension should be set to 23.5 to 25.5 N (84.5 - 91 ozf). Measurements should be made on the rear portion of the belt with the carriage positioned at either end of the travel. Once we reached the desired tension we can retighten the two hex bolts under the pulley to lock it in place.
