ZF 4699.300.134 SHIM | OEM Genuine Part

Overview

The ZF 4699.300.134 SHIM is a precision-engineered adjustment component designed to control axial play and preload within heavy-duty ZF powershift transmissions. Positioned between bearing races and gear faces, this OEM genuine part ensures correct gear mesh alignment and shaft end float. The SKU 4699.300.134 is critical for maintaining the tight tolerances required in construction machinery transmissions, preventing excessive movement that leads to premature wear. When installed alongside a BASIC GEARBOX (4699100080), this shim guarantees that all rotating assemblies remain within factory specifications.

Symptoms of Failure

• Excessive gear backlash or clunking during direction changes — A worn or incorrect shim allows the shaft to drift, creating audible impacts when load is applied.
• Transmission overheating due to incorrect bearing preload — Too much or too little preload from a degraded shim generates abnormal friction and heat buildup.
• Oil leaks at the shaft seal interface — Axial movement caused by a failed shim can distort the SHAFT SEAL (0634309122), leading to fluid seepage.
• Vibration or whining noise from the gear train — Misalignment from a collapsed shim forces gears to run out of parallel, producing tonal noise under load.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in wheel loaders, dozers, and graders. It is directly compatible with the WG180, WG200, and WG210 series. The part also fits select 4WG-200 and 6WG-200 models where axial shimming of the output shaft is required. For proper installation, always pair this shim with a new SEALING RING (0634801038) and verify the stack height using a SHIM RING (0630000091) to achieve the correct preload.
