ZF 4481.133.042 DIFFERENTIAL | OEM Genuine Part

Overview

The ZF 4481.133.042 DIFFERENTIAL is a critical torque-distributing component located within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part ensures that power from the driveline is split evenly between the left and right axles, allowing wheels to rotate at different speeds during turns while maintaining maximum traction on uneven terrain. The SKU 4481.133.042 sits directly between the output shaft and the axle shafts, housed within the main transmission casing. It is engineered to withstand extreme torsional loads and high-temperature operating conditions common in earthmoving equipment.

Symptoms of Failure

• Oil leaks around the differential housing: Worn seals or cracked casing on the 4481.133.042 allow transmission fluid to escape, leaving puddles under the machine and reducing lubrication to internal gears.
• Gear slipping during turns: When the differential fails to lock or unlock properly, operators experience sudden loss of drive power or jerky movements when maneuvering in tight spaces.
• Grinding or whining noise from the axle area: Damaged spider gears or worn bearing surfaces inside the differential produce a metallic grinding sound that intensifies under load.
• Uneven tire wear or reduced traction: A failing differential cannot distribute torque correctly, causing one wheel to spin freely while the other remains stationary on loose surfaces.

Technical Specifications

Compatibility

This differential is designed for use in ZF WG180, WG200, and WG210 series transmissions commonly installed in wheel loaders, graders, and telehandlers. It also fits select models of the ZF 4WG-200 and 6WG-200 power shift transmissions. Always verify the exact transmission serial number before ordering, as minor variations exist between early and late production units.
