Frequently Asked Questions

When should I replace a camshaft bushing?

Whenever you’re rebuilding the engine, if you notice camshaft play, or if oil pressure issues occur near the cam journal.

Do I need special tools to install it?

Should I replace other parts at the same time?

It’s best to replace bushings when installing a new Cummins camshaft or valve tappets to ensure proper valvetrain operation.
