Note: If you notice any resistance while tightening the carbon brush cap, it is an indication
that the top plate on the carbon brush assembly is sticking inside the brush cap.
Continuing to tighten will damage the carbon brush spring. (Go to step 6 to correct
this problem)
5. Tighten cap until secure as shown in
Figure 26.
