The Impact 9822556 Snap Ring is a precision-engineered retaining ring used in various locations within Impact 1640 pressure washer pumps and mechanical assemblies. It fits into a machined groove to secure components such as bearings, shafts, pistons, or gears, preventing axial movement during operation.
Snap rings are critical for maintaining proper internal clearances and component alignment. A missing, distorted, or worn snap ring can allow parts to shift, leading to increased wear, noise, loss of performance, or catastrophic internal failure. Replacing with a new snap ring ensures reliable component retention and extends equipment life.

When replacing a snap ring, these components are often inspected or replaced at the same time to ensure complete assembly integrity.
If the snap ring failed, bearings may have been impacted; inspect for roughness or wear.
Inspect the shaft or piston for grooving or damage where the ring seats.
If disassembly was required, replace any seals or gaskets disturbed during service.
