ZF 4699.801.172 GK10LD | OEM Genuine Part

Overview

The ZF 4699.801.172 GK10LD is a genuine OEM gearbox component engineered for the demanding environment of construction machinery. This part functions as a critical load-bearing and alignment element within the transmission assembly, ensuring precise gear meshing and torque transfer under heavy stress. Specifically, it sits in the lower drivetrain section, interfacing directly with the output shaft and housing to maintain structural integrity. The SKU 4699.801.172 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life when replacing worn units in the field.

Symptoms of Failure

• Transmission oil leaks around the housing joint: When the 4699.801.172 seal surface degrades, pressurized fluid escapes, often visible as drips under the machine. This is a common long-tail search query for “ZF transmission oil leak repair.”
• Gear slipping under load: A worn part can cause misalignment, leading to intermittent power loss or slipping during excavation or lifting operations.
• Unusual grinding or whining noise: As the component wears, metal-on-metal contact produces a distinct high-pitched sound, especially when shifting gears or reversing.
• Vibration in the driveline: Excessive play in this assembly translates to noticeable shaking through the chassis, often misdiagnosed as a bearing failure.

Technical Specifications

Compatibility

This genuine ZF 4699.801.172 part is designed for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG220. It is also compatible with certain variants of the WG150 series. Always verify your transmission serial number before ordering.

Installation Context

During replacement of the 4699.801.172, it is standard practice to inspect and replace adjacent components that share the same assembly. The 4699101106 HOUSING must be checked for cracks or wear, as it directly supports this part. The 4699103070 OUTPUT shaft should be examined for spline damage. Additionally, the 0501329881 HOUSING COVER and the 0630513065 SNAP RING are frequently replaced simultaneously to ensure a sealed, vibration-free fit.
