Retaining RingReference AC0000-84029 is stocked as an aftermarket replacement; we recommend confirming compatibility with your serial number before ordering. Retaining ring used to axially locate bearings, gears, and shafts inside transmissions, mast bushings, and hub assemblies. A correctly sized ring keeps assemblies stacked exactly as the designer intended. Drivetrain and hub rebuilders ordering retaining hardware during teardown make this part of every kit they pull together. A missing or fatigued retaining ring lets shafts walk out of position and can destroy an entire assembly, which is why fresh rings belong in every rebuild kit.Aftermarket replacement part, cross-references original part number AC0000-84029.Need help confirming fit?
