Description
What does a piston and liner shim do?
This piston and liner shim is a precision adjustment component designed to be installed between the cylinder liner and the engine block seating surface. In heavy-duty diesel engines, these shims are critical for setting the exact liner protrusion, which directly determines the clamping pressure on the cylinder head gasket. Maintaining this precise clearance is essential for preventing leaks and ensuring long-term engine sealing under high combustion pressures.Vehicle compatibility and application
This specific shim is compatible with Mercedes-Benz engines. It is engineered to meet high-strength requirements for heavy commercial vehicle applications, providing a stable interface between the liner and the block during engine overhauls or liner replacements.Installation and maintenance guidance
When performing an engine overhaul, technicians must measure the current protrusion to select the correct thickness from a graduated series. This 0.15 mm shim is intended for applications requiring specific height adjustments to maintain proper compression and oil control within the cylinder assembly.Troubleshooting and selection
Proper selection of the shim thickness prevents improper gasket loading, which can lead to premature engine failure or coolant contamination. Always verify the measured liner depth before installing this component to ensure it meets the required technical specifications for the specific engine series.OE cross-reference
1100 02 022 (Piston & Liner Shim) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number 4420110259.Technical Specifications

FAQ
What is the purpose of a piston and liner shim?
It is an adjustment ring used to set the correct cylinder liner protrusion, ensuring proper clamping pressure on the cylinder head gasket for effective sealing.
How do I select the correct shim thickness?
The thickness must be selected based on precise measurements taken during an engine overhaul or when replacing a cylinder liner to achieve target protrusion.
Can these shims be used in light passenger cars?
No, these are heavy-duty components specifically designed for heavy commercial vehicle engines like those found in trucks and buses.
What happens if the shim thickness is incorrect?
Incorrect thickness can lead to improper liner protrusion, resulting in insufficient or excessive gasket clamping pressure, which may cause engine leaks.
What are the OE reference numbers of this part?
1100 02 022 directly replaces Mercedes-Benz OE number 4420110259.
