ZF 4699.001.072 GK10 | OEM Genuine Part

Overview

The ZF 4699.001.072 GK10 is a genuine OEM component engineered for the internal clutch and gear actuation system within heavy-duty ZF transmissions. This part number, SKU 4699.001.072, functions as a critical hydraulic or mechanical interface element, often serving as a piston, guide, or shift element within the transmission valve body or clutch pack assembly. It is designed to withstand high cyclic loads and thermal stress in construction machinery applications. When installed, this component works in direct conjunction with the 4699101080 HOUSING to ensure precise oil flow and pressure regulation. The 0501329881 HOUSING COVER seals the assembly, while the 0630513065 SNAP RING secures axial positioning, and the 0634306309 O-RING prevents internal fluid bypass.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: When the 4699.001.072 wears, hydraulic pressure drops, causing harsh or slow clutch application.
• Internal transmission oil leaks: A worn sealing surface on this part allows fluid to bypass, leading to low line pressure and overheating.
• Torque converter shudder or slipping: Loss of control pressure from a degraded GK10 element results in torque converter clutch slip under load.
• Metallic debris in oil pan: Advanced wear of the component generates fine metal particles, often found during routine filter changes.

Technical Specifications

Compatibility

This genuine ZF part is primarily designed for use in the WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, dozers, and graders. It also fits select models of the Ecomat 4HP and 5HP series used in construction machinery. The 4699.001.072 is a direct replacement for the original GK10 assembly and requires the 4699101080 HOUSING for proper mounting. Always verify your transmission model tag before ordering.
