FAQ

Q1: How do I confirm this valve spring fits my engine?
A: This part is specifically manufactured for the Liebherr D934 engine. To confirm fitment, please check your engine nameplate or service manual to ensure the engine model is D934. Additionally, you can measure the free length, outer diameter, and wire diameter of your old spring and compare them to the OEM specifications for the D934 engine.

Q2: Should I replace all valve springs at once during an engine overhaul?
A: Yes, it is highly recommended to replace all valve springs as a set during a major overhaul or cylinder head service. Springs weaken over time due to fatigue. Replacing only one or two can lead to uneven valve seating and potential engine performance issues. This ensures consistent spring pressure across all cylinders.

Q3: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. The process typically involves removing the cylinder head, using a valve spring compressor to decompress the spring, and carefully removing the keepers (collets) and retainer. When installing the new spring, ensure it is seated properly on the cylinder head and that the valve stem seal is replaced simultaneously. Always refer to the official Liebherr service manual for torque specifications and specific procedures.
