Yamada 773092 Throat Bearing for Yamada AODD Pumps
The Yamada 773092 is a genuine Yamada throat bearing, used in Yamada air-operated double diaphragm (AODD) pumps. It supports and guides the center rod as it reciprocates through the pump's throat bore, carrying the side load of the stroke and preventing the rod from wearing the bore oversized.
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: 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.
Q: How do I know this is the right part for my pump?
Match the part number to the exact model and suffix on your pump nameplate, since Yamada pumps of the same nominal size can use different internal components depending on the body material and diaphragm elastomer ordered.
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.
