FAQ

Q: How can I confirm this valve guide fits my specific Liebherr D934 engine?
A: We recommend matching the physical dimensions and shape with your original worn guide. The most reliable method is to reference the OEM part number from your engine’s official service parts book. This part is manufactured to the OEM size specification for the D934 model.

Q: What is the recommended installation procedure for this valve guide?
A: Installation requires specialized tools and knowledge. Typically, the old guide is pressed out and the new one is pressed into the machined bore in the cylinder head, often requiring heating of the head and/or cooling of the guide. We advise following the official Liebherr workshop manual procedures. Ensure the guide is installed to the correct depth and that the valve stem clearance is checked after installation.
