(b) Make sure the gage is on the bottom of the groove.
(c) Pass the gage through the ends of the circlip.
(d) Move the gage back and forth.

• When moved back and forth, the gage must be clear of the inside edge of the top of
the circlip.
(10) If the gage does not move freely between the ends and under the top of the circlip, the
circlip seating is not correct. Install the circlip again and complete a check of the circlip
seating again per the previous steps. The circlip must be seated correctly.
