ZF 4699.102.022 INPUT | OEM Genuine Part

Overview

The ZF 4699.102.022 INPUT is a critical OEM genuine component engineered for the high-torque input stage of ZF heavy-duty powershift transmissions. This part serves as the primary interface between the engine flywheel and the transmission’s internal gear train, ensuring precise power transfer and smooth engagement under extreme loads. Identified by the SKU 4699.102.022, this input assembly is machined from high-strength alloy steel to withstand continuous shock loads in construction machinery. It integrates directly with the 4699300139: HOUSING and the 4699300156: GEAR SHAFT to form the core of the driveline, while the 4699100085: BASIC PARTS kit provides the necessary seals and bearings for a complete rebuild.

Symptoms of Failure

When the ZF 4699.102.022 INPUT begins to wear, operators typically notice these specific failure indicators:

• Torque converter shudder or vibration during low-speed maneuvering, often misdiagnosed as a clutch issue.
• Oil leaks at the bell housing caused by degradation of the input shaft seal surface or bearing bore wear.
• Delayed engagement or gear slipping under load, particularly when shifting from neutral to forward or reverse.
• Metallic debris in transmission fluid from spline wear or pitting on the input gear teeth.

Technical Specifications

Compatibility

This 4699.102.022 INPUT is designed for use in ZF WG series powershift transmissions commonly found in wheel loaders, graders, and dozers. It is directly compatible with the following ZF transmission models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310 (early production variants)

For a full rebuild, this input shaft must be paired with the 4699300127: PLANET CARRIER and the 4699300139: HOUSING to ensure correct gear mesh alignment.
