ZF 4699.801.114 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.114 GK10 is a critical OEM genuine gearset assembly designed for heavy-duty construction machinery transmissions. This part functions as the primary reduction gear cluster within the transmission housing, converting high-speed input torque from the engine into usable low-speed, high-torque output for demanding applications like wheel loaders and graders. The SKU 4699.801.114 is precision-engineered to maintain exact gear mesh tolerances, ensuring smooth power flow and extended service life in ZF drivelines. It sits directly between the input shaft and the output shaft, often secured within the 4699101090: HOUSING, which provides structural support and lubrication channels for the assembly.

Symptoms of Failure

When the ZF 4699.801.114 GK10 begins to wear, operators often notice distinct operational issues that signal imminent failure. Common long-tail search queries include:

• Whining or grinding noise during gear engagement: Worn gear teeth cause irregular contact patterns, producing a high-pitched whine under load.
• Intermittent gear slipping under heavy load: Reduced tooth profile integrity leads to momentary loss of torque transfer, especially in lower gears.
• Metal particles in transmission fluid: Flaking or pitting on the gear surfaces contaminates the oil, visible during routine drain intervals.
• Vibration through the driveline at specific RPMs: Uneven wear on the GK10 creates harmonic imbalances that resonate through the 0501329881: HOUSING COVER.

Technical Specifications

Compatibility

This OEM genuine GK10 is engineered for use in ZF WG-series powershift transmissions commonly found in construction machinery. It is directly compatible with the following transmission models:

• ZF WG180 – 6-speed powershift, used in wheel loaders (e.g., Volvo L70, Caterpillar 950).
• ZF WG200 – 6-speed heavy-duty variant, used in graders and compact loaders.
• ZF 4WG-200 – 4-speed version with integrated torque converter.
• ZF 6WG-250 – Larger frame transmission for articulated dump trucks.

During installation, ensure the 0634306309: O-RING is replaced to prevent fluid bypass between the housing and cover. Additionally, the 0637885612: BREATHER should be inspected for clogging to maintain proper internal pressure equalization.
