Caterpillar C15 Industrial Engine — Engine Valve Rotators - Inspect
Maintenance
For the Caterpillar C15 Industrial Engine, from the Caterpillar owner's manual.
Applies to: Caterpillar C1.5 engine
Before you start
- A valve rotator which does not operate properly will accelerate valve face and seat wear and shorten valve life.
Procedure
- Wear protective glasses or face shield and protective clothing to prevent burns from hot oil or spray.
- After the engine valve lash is set, start the engine and operate at low idle.
- Observe the top surface of each valve rotator. The rotators should turn slightly when the valves close.
- If a valve fails to rotate, consult your Caterpillar dealer.
