5. Compare the measured belt tension to the second stage drive belt tension specification.
System Component Specification
Second Stage Belt Drive Tension - New 110-120 lbs (50- 54.4 kgs)
Second Stage Belt Drive Tension - Used 92 - 105 lbs (43 - 47.6 kgs)
Note:New belt tension applies to new belt first time installations. Used belt tension
applies to reinstalling an existing belt or re-tensioning an existing used belt.
6. If the tension is not within the specified limits, do the following tension adjustment steps
to bring the tension within specification:
a. Remove the belt tension gauge.
b. Make a small incremental adjustment to the 1/2" Second Stage Belt Tensioner
bolt as needed (loosen or tighten) to bring the belt tension into specification.
Note:Belt tension adjustment is an iterative process, only make small
tension changes per adjustment. Be careful to NOT over tension the
belt, which could result in damaging the belt or pulley hardware.
