Cylinder Liner Shim
Cummins®

Introduction

The 124320 Cylinder Liner Shim, a component designed by Cummins for heavy-duty truck engines, ensures proper alignment and spacing between the cylinder liner and the engine block. This part is essential for maintaining the integrity of the engine’s combustion process by facilitating accurate piston movement and cylinder sealing ¹.

Basic Concepts

A Cylinder Liner Shim is a thin, metallic spacer placed between the cylinder liner and the engine block. It provides the necessary clearance and alignment for the cylinder liner, ensuring it sits correctly within the engine block. This alignment is vital for the piston’s smooth movement within the cylinder, affecting the engine’s compression and combustion efficiency ³.

Purpose of the 124320 Cylinder Liner Shim

This Cummins part ensures that the cylinder liner is properly positioned within the engine block, maintaining the engine’s compression ratios and efficient power transfer from the combustion process to the piston’s movement. Precise alignment reduces wear on the cylinder liner and enhances the engine’s longevity and performance ⁴.

Key Features

The 124320 is characterized by its specific material composition, chosen for durability and resistance to high temperatures and pressures within the engine. Its design specifications are tailored to fit precisely within the engine’s architecture, ensuring optimal performance. Unique attributes may include its calibrated thickness for exact clearance and a surface finish designed to minimize friction and wear ².

Benefits

The advantages of the 124320 include improved engine efficiency through precise alignment of the cylinder liner, leading to better compression and combustion. It reduces wear on the cylinder liner by preventing undue stress or misalignment. Furthermore, it enhances the overall reliability of the engine by maintaining the integrity of the combustion process and the mechanical precision of the engine’s moving parts ¹.

Installation Process

Proper installation of the 124320 involves several steps to ensure optimal performance. It begins with preparing the engine block and the cylinder liner to ensure they are clean and free from debris. The shim is then placed between the cylinder liner and the engine block, ensuring correct alignment. Tools such as torque wrenches may be used to secure the cylinder liner in place, following the manufacturer’s specifications for torque settings. It is important to follow recommended procedures to ensure the shim is installed correctly and functions as intended within the engine ².

Troubleshooting and Maintenance

Identifying common issues related to the 124320 may involve checking for signs of wear or misalignment of the cylinder liner. Diagnostic procedures can include visual inspections and measurements to ensure the shim is correctly positioned and that the cylinder liner is not excessively worn. Maintenance practices to prolong the lifespan of the shim and ensure continued engine performance may include regular inspections and replacements as necessary, following the manufacturer’s guidelines for maintenance intervals ³.
