Place the tips of the retaining ring pliers into the eyelets of the retaining ring.

Guide the retaining ring with your finger to prevent the shaft from from getting scratched while installing the retaining ring. Use the pliers to push the seal head into the upper tube while installing the retaining ring into the groove. Release the retaining ring pliers when the ring is fully seated in the groove.

Confirm the retaining ring is properly seated in the retaining ring groove by using the retaining ring pliers to rotate the retaining ring and sealhead back and forth a few times.

Notice

Do not scratch the air spring shaft. Scratches on the air shaft will allow air to bypass the sealhead into the lower leg, resulting in reduced spring performance.

Warning

CRASH HAZARD: Retaining rings must be fully seated in the retaining ring groove. Confirm the retaining ring is fully seated in the retaining ring groove after installation. Failure to do so can result in SERIOUS INJURY OR DEATH.
