ZF 4143.352.040 END SHIM | OEM Genuine Part

Overview

The ZF 4143.352.040 END SHIM is a precision-engineered OEM genuine component designed to control axial play and maintain critical clearances within ZF HL 100 and HL 270 series transmissions. This hardened steel shim sits between the housing assembly and rotating elements, ensuring proper preload on bearings and shafts. The SKU 4143.352.040 is often selected during rebuilds to restore factory tolerances, preventing premature wear on adjacent components such as the 4143101016 HOUSING and 4143301039 HOUSING. Without this end shim, gear alignment drifts, leading to accelerated fatigue across the entire drivetrain assembly.

Symptoms of Failure

• Excessive end float or axial movement – A worn or missing 4143.352.040 shim allows the shaft to shift, causing a noticeable clunk during load changes and reducing shift quality.
• Oil leaks near the housing joint – When the shim compresses or deforms, the seal between the 0501318136 GASKET and housing is compromised, leading to fluid seepage.
• Gear slipping under torque – Incorrect shim thickness alters gear mesh depth, resulting in intermittent power loss and harsh engagement.
• Vibration at specific RPM ranges – Worn end shims allow bearing race movement, transmitting resonance through the 0636101084 CAP SCREW fasteners and surrounding structure.

Technical Specifications

Compatibility

This end shim is engineered for ZF HL 100 and HL 270 series transmissions, including models such as WG180, WG200, and WG210. It is also used in certain 4WG-200 and 6WG-200 variants where axial shimming of the output shaft is required. Always verify stack height using the original service manual, as multiple shim thicknesses may be combined. For complete rebuilds, pair this shim with a new 0501318136 GASKET and inspect the 4143101016 HOUSING for wear on the mating face.
