Overview
The ZF 4061.313.210 DIFF.AXLE for WG200 is a critical differential axle component engineered for the robust ZF WG200 series powershift transmission. This OEM genuine part, identified by SKU 4061.313.210, serves as the primary interface between the transmission output and the final drive, managing torque distribution and enabling smooth cornering under heavy loads. Positioned within the rear axle housing assembly, this differential axle works in concert with the 4469315012: AXLE DRIVE HOUSING to ensure precise gear alignment and load-bearing capacity. Manufactured to ZF’s exacting tolerances, the 4061.313.210 is a direct replacement part that restores original performance in off-highway vehicles, construction equipment, and agricultural machinery.
Symptoms of Failure
When the ZF 4061.313.210 DIFF.AXLE begins to wear, operators typically notice three distinct failure modes. First, intermittent gear slipping under load occurs as the axle’s splines lose engagement with the differential side gears, causing power loss during acceleration. Second, persistent oil leaks around the axle housing develop when the shaft seal fails, often accompanied by a visible puddle of transmission fluid beneath the vehicle. Third, a rhythmic clunking noise during turns signals excessive play between the axle and the 4460115043: HOUSING, indicating that the differential axle has worn beyond service limits. Left unaddressed, these symptoms can lead to catastrophic gear damage and complete transmission failure.

Compatibility
This ZF 4061.313.210 DIFF.AXLE is specifically designed for the WG200 transmission series, but it also cross-references with select models in the WG180 and WG240 families that share the same differential architecture. The part is compatible with ZF’s powershift transmissions found in Case IH, New Holland, and Deutz-Fahr agricultural tractors, as well as Volvo and Caterpillar wheel loaders. For proper installation, this axle must be paired with the 0750117406: TAPER ROLLER BEARING on the input side and the 0750117802: TAPERED ROLLER BEARING on the output side to maintain correct preload and axial clearance.
