ZF 4699.300.133 SHIM | OEM Genuine Part

Overview

The ZF 4699.300.133 SHIM is a precision-engineered OEM genuine part designed to establish the correct axial clearance and preload within heavy-duty construction machinery transmissions. This thin, hardened steel component sits between the gear train and the bearing race, compensating for manufacturing tolerances to ensure optimal gear mesh alignment. As a critical adjustment element, the SKU 4699.300.133 directly influences the longevity of the entire rotating assembly. When paired with a BASIC GEARBOX, this shim prevents destructive end-play that can lead to premature component fatigue.

Symptoms of Failure

• Excessive axial play in the output shaft – A worn or collapsed shim allows the shaft to move laterally, causing a noticeable clunk during gear engagement and load reversal.
• Persistent oil seepage from the PTO housing – Incorrect shim thickness misaligns the shaft, distorting the SHAFT SEAL and creating a path for fluid migration.
• Gear whine under load – Loss of preload from a fatigued shim allows gear teeth to contact improperly, generating a high-pitched metallic noise during acceleration.
• Intermittent transmission slipping – When the shim stack collapses, the clutch pack clearance increases, leading to delayed engagement and power loss.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG180, WG200, and WG210 series power shift transmissions commonly found in wheel loaders, graders, and material handlers. It is also utilized in the 4WG-200 and 6WG-200 variants where precise bearing preload is required. Always verify the existing shim stack thickness before replacement; a SHIM RING may be needed in combination to achieve the correct total clearance. For applications using a SEALING RING, ensure the shim surface is free of burrs to prevent damage during installation.
