This piston assembly, complete with piston rings, is designed for the repair and maintenance of compatible Liebherr® engines. The package includes the engine piston and the corresponding piston rings, providing a convenient, perfectly matched replacement solution.

The piston plays a central role in the engine: it transfers the force generated during combustion to the connecting rod and crankshaft. The piston rings assist in sealing the combustion chamber, dissipating heat, and regulating the oil film on the cylinder wall. Worn or damaged components can lead to power loss, increased oil consumption, rough engine operation, or reduced compression.

This replacement part is particularly suitable for engine repairs, overhauls, and scheduled maintenance on construction machinery, mobile cranes, and other equipment powered by compatible Liebherr® engines.

Frequently Asked Questions (FAQ)


Are the piston rings pre-installed?


No, the piston rings are typically included in the set in separate packaging to prevent damage during transport. Use piston ring pliers during installation to insert the rings without placing undue stress on them. What piston ring end gap must be maintained?

Before installation, you should check the end gap of each piston ring individually within the cylinder liner. Strictly adhere to the repair and adjustment specifications found in the Liebherr® engine manual for the D934/D936 series.


Is this piston compatible with a piston cooling jet?

This piston (Ref. No. 10115834) is designed for versions without an integrated cooling gallery. Before purchasing, please check your old part number or the chassis/engine number to verify the correct variant.




Before ordering, please compare reference number 10115834 and the technical specifications of the existing component. Exact compatibility depends on the engine and machine model.
