FAQ

Q1: How can I confirm this camshaft (3966430) is the correct part for my Cummins 6D114 engine?
A: Please verify your engine’s serial number and the existing camshaft part number. This part is designed as a direct OEM replacement for the 3966430. We recommend comparing the cam lobe profiles and overall dimensions with your old part. If in doubt, send us a photo of your old camshaft or engine plate for cross-verification.

Q2: What is the installation procedure for this camshaft?
A: Installation should be performed by a qualified diesel mechanic. The process typically involves removing the valve cover, rocker arms, and timing gear. The new camshaft must be lubricated with clean engine oil during installation. Torque all bolts to manufacturer specifications and re-time the engine according to the Cummins 6D114 service manual. We recommend replacing cam followers and seals simultaneously for optimal performance.

Q3: What maintenance is required after installing a new camshaft?
A: After installation, start the engine and check for proper oil pressure and listen for unusual noises. Run the engine at idle for 10-15 minutes to allow the camshaft to break in. Check and adjust valve clearances after the initial 50 hours of operation. Use high-quality diesel engine oil with the correct viscosity (typically 15W-40) and change the oil and filter as per the engine manufacturer’s schedule to ensure long camshaft life.
