(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 shoudl 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 retigthen the two hex bolts under the pulley to lock it in place.
