ZF 0501.324.905 WHEEL | OEM Genuine Part

Overview

The ZF 0501.324.905 WHEEL is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery transmissions. This precision-machined wheel functions as a load-bearing interface within the planetary gear set, transferring rotational torque from the sun gear to the planet carrier while maintaining exact axial alignment. As an integral part of the drivetrain, the SKU 0501.324.905 ensures smooth power distribution under extreme loads, directly influencing machine tractive effort and operational stability. It is commonly found in ZF powershift transmissions where gear meshing precision is non-negotiable.

Symptoms of Failure

• Intermittent gear slippage under load – A worn 0501.324.905 wheel can cause uneven tooth contact, leading to momentary loss of torque transfer when the machine is pushing heavy material.
• Metallic grinding noise from the transmission housing – As the wheel surface degrades, particulate contamination generates audible friction, often misdiagnosed as bearing failure.
• Increased transmission oil temperature – Excessive play in the wheel assembly creates internal drag, causing the hydraulic fluid to overheat during extended operation cycles.
• Vibration through the chassis during gear engagement – A failing wheel disrupts the concentric rotation of the planetary set, transmitting harmonic tremors to the operator cab.

Technical Specifications

Compatibility

This genuine ZF wheel is designed for use in the WG180, WG200, and WG211 series powershift transmissions, commonly deployed in wheel loaders, graders, and telehandlers. It also fits select iterations of the ZF 4WG-200 and 6WG-200 drivelines. Always verify the transmission serial number against the OEM parts catalog before installation, as minor spline variations exist between early and late production models.
