Rigidly attach dial indicator to the air line support or other sta-
tionary object. Measure run-out of the rotary joint (See Figure 5).
Rotate hub 360° to locate point of minimum reading on the dial;
set indicator to read zero at this point.
Figure 5
Rotate coupling 360° while watching indicator at rotary
joint for misalignment reading. Total indicated run-out
should be 0.005". If run-out is over 0.005", mark low point
on face of coupling. Install shims under hub at low point
(See Figure 6).
