ZF 4695.301.012 SHIM | OEM Genuine Part

Overview

The ZF 4695.301.012 SHIM is a precision-engineered spacer component designed to establish critical axial clearances within ZF heavy-duty powershift transmissions. Positioned between the transmission housing and planetary gear assemblies, this OEM genuine part ensures correct end-play tolerances for rotating shafts and clutch packs. The SKU 4695.301.012 is a factory-specified shim that prevents metal-to-metal contact and maintains hydraulic pressure integrity. When installed alongside the 4695101002 HOUSING or the 4695301021 HOUSING, this shim guarantees that gear alignment remains within OEM specifications, directly influencing torque transfer efficiency in construction machinery drivetrains.

Symptoms of Failure

• Intermittent gear slippage under load – Worn shims allow excessive axial play, causing clutch packs to lose hydraulic clamping force during heavy excavation or grading operations.
• Metallic grinding noises from transmission sump – A degraded 4695.301.012 shim permits planetary gears to contact the 4695301022 COVER, producing audible debris contamination.
• Hydraulic pressure fluctuations – Incorrect shim thickness disrupts oil flow paths, leading to erratic shift timing and delayed engagement in forward/reverse ranges.
• Premature seal failure – Axial movement caused by a collapsed shim stresses the 0634801038 SEALING RING, resulting in external oil leaks near the PTO housing.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly used in wheel loaders, dozers, and telehandlers. Based on its dimensional profile and application in clutch pack preload adjustment, the 4695.301.012 is compatible with the following transmission models:

• ZF WG180 (all series)
• ZF WG200 (early and late production)
• ZF 4WG-180
• ZF 4WG-200
• ZF 5WG-200 (select variants)
