ZF 4695.301.011 SHIM | OEM Genuine Part

Overview

The ZF 4695.301.011 SHIM is a precision-engineered OEM genuine part designed for critical axial clearance adjustment within ZF heavy-duty transmissions. This thin, hardened steel component sits between the transmission housing and bearing assemblies, ensuring correct preload and alignment of rotating shafts. By maintaining exacting tolerances, the 4695.301.011 prevents metal-to-metal contact and compensates for thermal expansion during operation. As a factory-specified shim, it is essential for restoring factory-specified gear mesh patterns and preventing premature wear in construction machinery transmissions. The SKU 4695.301.011 is frequently replaced during a full transmission rebuild alongside the 4695101002: HOUSING and 4695301021: HOUSING to guarantee proper assembly geometry.

Symptoms of Failure

• Transmission whining or howling noise under load: When the 4695.301.011 shim wears or compresses beyond tolerance, gear backlash increases, producing a distinct high-pitched whine during acceleration or heavy digging operations.
• Intermittent gear slipping or delayed engagement: Incorrect shim thickness allows shaft end-play, causing clutch packs to lose hydraulic pressure and slip under torque, especially in WG180 and WG200 series transmissions.
• Metallic debris in transmission oil: A collapsed or cracked shim can fragment, sending steel particles through the oil system, often detected during routine filter inspections or magnetic drain plug checks.
• Vibration at specific RPM ranges: Worn shims permit shaft wobble, creating harmonic vibrations that are most noticeable at operating speeds between 1500-2200 RPM in construction loaders and graders.

Technical Specifications

Compatibility

This shim is specifically engineered for ZF powershift transmissions commonly used in construction machinery. It is a direct fit for the following ZF transmission models: WG180, WG200, WG120, and WG150 series. The 4695.301.011 is also compatible with certain variants of the 4WG-200 and 5WG-200 transmissions found in wheel loaders, dozers, and telehandlers. Always verify the shim stack thickness during installation, as multiple shims may be combined to achieve the specified end-play. For complete assembly, pair this shim with the 4695301022: COVER and the 0634801038: SEALING RING to prevent oil bypass and maintain pressure integrity.
