Jabsco 18753-0434 O-Ring Gasket for 18785-0000 Cam Liner
The Jabsco 18753-0434 is a genuine Jabsco O-ring gasket that seals the 18785-0000 cam liner in large engine cooling pumps. It is listed for the Jabsco 18770-0003 bronze engine cooling pump.
O-rings seal the joints between fixed parts of the pump. Once an O-ring has been compressed in service it takes a set and may not reseal, so fit a new one whenever the joint is opened. Check the groove is clean and undamaged, lubricate the O-ring lightly with a grease that suits the material, and make sure it is not twisted or pinched as the parts come together.

Frequently Asked Questions
Q: How do I know the material is right?
Match the material to the liquid. Nitrile suits oils and fuels, FKM suits many chemicals and higher temperatures, and EPDM suits hot water and many cleaning solutions.
Q: Why does a new O-ring still leak?
Check for a damaged groove, dirt on the sealing faces, or an O-ring that was twisted or pinched on assembly.
Q: Should I keep spares?
Yes. O-rings are small, inexpensive and easy to lose during a rebuild.
Q: Can I reuse the old O-ring?
It is not recommended. A used O-ring has taken a set and often leaks when the joint is reassembled.
