Jabsco 18913-0003 Cam and Bearing Kit
The Jabsco 18913-0003 is a genuine Jabsco cam and bearing kit for a Jabsco diaphragm water pump. The cam and bearing convert the motor rotation into the stroke that drives the diaphragm. It is listed for Jabsco 31801 series diaphragm pumps.
Diaphragm water pumps rely on the valves, diaphragm and housings sealing well to build and hold pressure. Worn valves or a torn diaphragm show up as a pump that cycles, will not hold pressure, loses flow or will not prime. Replace worn parts as a set where possible, keep the pump clean inside, and protect it from freezing.

Frequently Asked Questions
Q: How do I protect the pump over winter?
Drain the pump and the system, or use a potable antifreeze made for water systems.
Q: Should I fit a strainer?
Yes, a strainer on the suction side keeps debris out of the valves.
Q: Can I rebuild the pump myself?
Yes, with basic tools. Note the orientation of each part as you remove it.
Q: Why does my pump cycle when no tap is open?
Leaking valves, a system leak or a worn pressure switch are the usual causes.
