2. Insert the points of the pliers into the holes of the snap ring. Apply enough pressure to spread the snap ring so
it can be removed.
3. Remove the Retaining Ring.
4. Install the new retaining ring by reversing steps 1-3 above.
NOTE
If you are installing a threaded ring, make sure the threads go on first. If you are installing the SpeedLok™ style with
two pins instead of threads, make sure the pins go on first.
5. Verify that the snap ring is properly seated in the groove. To do this, check the snap ring gap and movement of
the retaining ring. The gap should not be more than 1/8" (3mm) and the retaining ring should turn freely on the
cartridge. If not, then use the tips of the pliers or a flat blade screwdriver to press downward on the ring until it
snaps into place and both items are correct.
6. This completes the instructions for replacing the cartridge retaining ring.
