Yamada 803675 Sleeve Assembly for Yamada AODD Pumps
The Yamada 803675 is a genuine Yamada sleeve assembly, used in Yamada air-operated double diaphragm (AODD) pumps. It is a precision-fit wear sleeve assembly, supplied complete with its O-ring seal, that guides a reciprocating component while sealing against air or fluid bypass around it.
Genuine Yamada replacement parts are machined and molded to the original factory tolerances, so fit, alignment and seal engagement match the component being replaced. One per pump. Always compare the exact part number against your pump's nameplate before ordering, since Yamada varies internal components by both pump size and body material / elastomer combination.

Frequently Asked Questions
Q: Do I need any other parts to complete this repair?
Depends on what you are replacing this alongside. Anything the pump was disassembled to reach - gaskets, O-rings, seals - should be replaced as a set rather than reused, even if this is the only part that visibly failed.
Q: What symptoms suggest this component needs replacing?
Erratic cycling, stalling, unusual noise from the affected area, or visible wear, play, or damage on inspection are the usual signs that a specific internal component needs attention.
Q: Is this a wear item or does it last the life of the pump?
That depends on the specific component, but as a rule any part that moves, reciprocates, or seals against another part should be inspected whenever the pump is opened for service and replaced if it shows wear, scoring, or play.
Q: Can I install this myself, or does it need a service technician?
Most Yamada AODD pump components are designed for field service with basic hand tools, following the torque sequence and reassembly order in the pump's maintenance manual.
