ZF 4699.270.042 ASSEMBLY PARTS | OEM Genuine Part

Overview

The ZF 4699.270.042 ASSEMBLY PARTS component is a critical internal sub-assembly engineered for heavy-duty construction machinery transmissions. This OEM genuine part integrates directly into the clutch or planetary gear set housing, ensuring precise torque transfer and hydraulic pressure regulation within the transmission system. The SKU 4699.270.042 functions as a structural and hydraulic interface, supporting the HOUSING and aligning with the INPUT shaft assembly. Its robust construction is designed to withstand the high cyclic loads and thermal stress common in excavators, wheel loaders, and other off-highway equipment.

Symptoms of Failure

When the 4699.270.042 assembly wears out, operators may notice intermittent gear engagement hesitation during shifting under load. Another common failure sign is low hydraulic pressure at the clutch pack, often accompanied by erratic transmission temperature spikes. Additionally, a worn assembly can cause metallic debris in the transmission oil filter, indicating internal component degradation. These symptoms typically lead to reduced machine productivity and require immediate inspection of the OUTPUT side components.

Technical Specifications

Compatibility

This assembly is primarily compatible with ZF WG180, WG200, and WG250 series transmissions used in construction machinery. It also fits select variants of the ZF 4WG-200 and 6WG-200 power shift transmissions. The part interfaces directly with the GP25 gear pump assembly, which supplies hydraulic flow to the clutch circuits. Always verify your transmission model and serial number before ordering, as minor design revisions exist across different production years.
