Jabsco 18716-0000 Retaining Ring
The Jabsco 18716-0000 is a genuine Jabsco retaining ring — the circlip that locates the ball bearing within the pump. Jabsco specifies a particular ring size for each pump in its range, and the correct one is the one listed for your pump, not simply one that looks the same diameter.
That point matters more than it sounds. A ring that is slightly undersized will not seat properly in the groove and can spring free under vibration; one that is slightly oversized will not close down into the groove at all. Either way the bearing ends up unrestrained, and the damage that follows lands on parts far more expensive than the ring.
Jabsco uses several different retaining ring sizes and two distinct positions — one holding the bearing to the pump body and one holding it to the shaft — across its pump range. Rings from different models look very similar but are not interchangeable, so please confirm this part number against the parts list for your specific pump before ordering.
Fit a new ring whenever the bearing comes out. Use circlip pliers rather than screwdrivers, open it only as far as it needs to go, and confirm it has snapped fully home in its groove before reassembling the pump.

Frequently Asked Questions
Q: Is this a genuine Jabsco part?
Yes, this is a genuine Jabsco retaining ring, not an aftermarket substitute.
Q: How do I know which retaining ring I need?
Compare this part number to the number on your pump's parts diagram, or send us a picture of the part you are replacing so we can confirm.
Q: When should this ring be replaced?
Replace it whenever it is removed during a bearing or seal service, since a ring that has been sprung open or shows wear may not seat as securely the second time.
Q: Does this fit more than one Jabsco pump model?
Retaining rings of this type are often shared across several Jabsco pump series, so check your pump's own parts list or send us your model number to confirm exact fitment.
