Yanmar 22243-000200 Circlip
The Yanmar 22243-000200 is the genuine circlip for Yanmar marine diesel sea water pumps that use this part. It locates a bearing, a seal or a shaft component axially - a small spring steel ring seated in a groove that stops the part it retains from moving along the shaft or out of its bore.
Use the right pliers, seat the ring fully in its groove, and check that it has snapped home all the way round before the assembly is closed up.

Frequently Asked Questions
Q: Why not reuse the old ring?
Spreading it to remove it stretches it. A ring that no longer sits hard in its groove can work out under vibration, and whatever it was retaining then moves.
Q: How do I know it is properly seated?
Run a fingernail round it after fitting. It should be fully down in the groove the whole way round with no section standing proud.
Q: Does the ring have a correct way round?
Many do - a stamped ring has a sharp edge and a rounded one, and the sharp edge faces the load. Fitted backwards it holds considerably less.
Q: What happens if one comes out in service?
The bearing or seal it retained is free to move along the shaft, which destroys clearances and usually the pump with them.
