ZF 4699.270.049 ASSEMBLY PARTS | OEM Genuine Part

Overview

The ZF 4699.270.049 ASSEMBLY PARTS component is a critical internal sub-assembly engineered for heavy-duty construction machinery transmissions. This OEM genuine part functions as a precision-machined carrier and alignment hub within the planetary gear set, ensuring correct gear mesh and load distribution under extreme torque conditions. The SKU 4699.270.049 sits directly in the main drive path of the transmission, interfacing with the input shaft and output shaft to maintain concentric rotation. When installed alongside the 4699025169 GP25 gear pack, this assembly provides the structural foundation for reliable power transfer in wheel loaders and graders.

Symptoms of Failure

When the 4699.270.049 assembly wears out, operators typically notice intermittent gear slipping under load, particularly during directional shifts. A second common failure symptom is metallic grinding noises from the transmission housing, indicating bearing surface degradation. You may also observe erratic engagement of forward and reverse gears due to misalignment of the planetary carrier. Finally, contaminated transmission fluid with fine metal particles often signals that this assembly has begun to fracture, requiring immediate replacement to avoid cascading damage to the 4699101153 HOUSING.

Technical Specifications

Compatibility

This assembly part is designed for ZF WG180, WG200, and WG210 series transmissions commonly found in construction machinery such as Volvo L120 wheel loaders and Caterpillar 950G graders. It also fits select 4WG-200 and 5WG-210 variants used in heavy dump trucks. For proper installation, always pair this part with the 4699102130 INPUT shaft assembly and the 4699103122 OUTPUT flange to ensure correct axial clearance. Verify your transmission model number before ordering.
