How do I measure my air brake slack adjuster? The first step to determining which air brake
slack adjuster you need is to measure the diameter of the camshaft at the splines. You will then need to count
the splines. Finally, measure the distance from the center of the camshaft hole to the center of the clevis
pin hole. This measurement is referred to as the span in the chart below.
You'll also need to be aware of any offset from the center line of the slack adjuster arm
to the center of the brake chamber push rod. Most of the slack adjusters listed below are
not offset. Offsets will be listed in the notes under the part.
