ZF 4699.801.252 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.252 GK10 is a precision-engineered gear cluster assembly designed for heavy-duty construction machinery transmissions. This OEM genuine part functions as a primary power transfer component within the planetary gear set, converting rotational input into controlled output torque. The SKU 4699.801.252 is specifically machined to withstand extreme loads in excavators, wheel loaders, and crawler dozers. It integrates directly with the 4699001107: GK10 sub-assembly to ensure synchronized gear engagement under high-stress operating conditions.

Symptoms of Failure

• Intermittent gear slipping under load: When the 4699.801.252 wears, operators notice sudden loss of drive power during heavy digging or lifting cycles.
• Metallic grinding noise from transmission housing: Worn gear teeth produce a distinct high-pitched whine or grinding sound, especially during gear shifts.
• Hydraulic oil contamination with metallic particles: Debris from the failing gear cluster circulates through the system, often detected during routine oil analysis.
• Delayed engagement or harsh shifting: The transmission hesitates or clunks when transitioning between forward and reverse, indicating excessive gear backlash.

Technical Specifications

Compatibility

This genuine ZF part is engineered for the following transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG240 series. It is also compatible with certain variants of the Ecomat 2 and Ecomat 3 transmissions used in mobile cranes and concrete pumps. The 4699.801.252 GK10 directly interfaces with the 4699101095: HOUSING and the 4699102083: INPUT shaft assembly. For complete driveline restoration, pair it with the 4699103067: OUTPUT component.
