FAQ

Q1: How do I verify if this valve spring (4936076) fits my Cummins 6L or 6LT engine?

To ensure correct fitment, check your engine’s serial number and existing valve spring part number. The 4936076 is specifically designed for Cummins 6L and 6LT diesel engines. We recommend comparing the free length, inner diameter, and wire thickness of your current spring with the specifications provided. If possible, remove one spring and measure it against our technical data. For assistance, contact our technical support team with your engine model and serial number.

Q2: Can I replace individual valve springs, or should I replace them in sets?

While it is technically possible to replace a single damaged valve spring, we strongly recommend replacing all valve springs in a cylinder head as a complete set. This ensures uniform spring tension across all valves, preventing uneven wear, valve float, and potential engine damage. For optimal engine performance and reliability, always replace springs in matched sets, especially on high-hour engines or during a cylinder head rebuild.

Q3: What are the signs that my Cummins 6L/6LT valve springs need replacement?

Common indicators of worn or failing valve springs include: (1) Misfiring or rough idling due to improper valve seating; (2) Loss of engine power and reduced fuel efficiency; (3) Unusual ticking or tapping noises from the valve train area; (4) Valve float at higher RPMs causing hesitation or backfiring; (5) Visible cracks, rust pitting, or sagging on the spring itself. If you experience any of these symptoms, inspect the valve springs immediately. Regular replacement during major engine overhauls (typically every 8000-10000 hours) is recommended for preventive maintenance.
