ZF 4699.300.135 SHIM | OEM Genuine Part

Overview

The ZF 4699.300.135 SHIM is a precision-engineered OEM genuine part designed to establish the correct axial clearance and preload within ZF construction machinery transmissions. This shim sits between the bearing race and the housing, ensuring that rotating assemblies maintain their exact positional tolerances under heavy load. The SKU 4699.300.135 is critical for eliminating end-play in the main shaft cluster, directly influencing gear mesh alignment and overall driveline stability. When paired with a 4699100080: BASIC GEARBOX, this shim guarantees that the internal clearances match factory specifications, preventing premature wear on adjacent components.

Symptoms of Failure

• Transmission whine or howling under load: A worn or collapsed shim allows the shaft to drift axially, causing gear teeth to misalign and generate a distinct high-pitched noise during operation.
• Intermittent gear slipping in forward gears: Loss of correct preload reduces clutch pack clamping force, leading to momentary power loss when the machine is under heavy strain.
• Oil seepage from the main housing joint: Excessive axial movement can distort the 0634309122: SHAFT SEAL, allowing hydraulic fluid to escape past the seal lip.
• Vibration through the driveline at idle: Uncontrolled end-play creates a rhythmic shudder that is most noticeable when the transmission is in neutral but the engine is running.

Technical Specifications

Compatibility

This shim is specifically dimensioned for use in ZF WG-series powershift transmissions commonly found in wheel loaders and telehandlers. It is a direct fit for the WG180, WG200, and WG211 models. The part also appears in certain ERGOPOWER and ECOMIX drivelines where the main shaft bearing pack requires a 1.35 mm correction shim. Always verify the stack height when replacing a 0634801038: SEALING RING or a 0630000091: SHIM RING, as the cumulative clearance must remain within 0.05 mm of the factory target.
