FAQ

Q1: Is this piston a direct fit for my Liebherr D9508 engine?
A: Yes, part number 10148221 is a direct replacement piston for the Liebherr D9508 engine. However, we strongly recommend checking your engine’s serial number and the old piston’s specifications to confirm compatibility. Different engine series may have minor variations in compression height or pin diameter.

Q2: What other parts should I replace when installing a new piston?
A: For optimal performance and longevity, it is highly recommended to replace the piston rings, piston pin, and cylinder liner simultaneously. We also suggest replacing the connecting rod bearings and main bearings as part of a complete engine overhaul. We can supply a full piston kit or engine rebuild kit.
