Piston Ring Cummins C4932801 is an internal engine component: part of the assembly that turns combustion pressure into motion and keeps the cylinder sealed.
These parts are replaced on measurement, not on prevention. Oil consumption, blow-by at the breather, low compression or a metallic noise when cold are the signals that justify opening the engine.

How to verify before ordering
- Match the reference stamped on the part and the nominal or oversize dimension the engine needs.
- Check the engine serial range it belongs to; the same model can use two variants.
- Order the full gasket set and new head bolts where the job requires them: they are not reused.
- Declared make or line: CUMMINS. If your equipment carries another make, the part may not be equivalent.
Frequently asked questions
Can a single liner be replaced?
Technically yes, in practice the full set is changed. One new cylinder beside worn ones unbalances the engine and forces a second teardown.
How do I know I need an oversize?
By measuring bore or journal wear before ordering. Without that measurement the part may not seat and the job repeats.
