ZF 0501.325.062 WHEEL | OEM Genuine Part

Overview

The ZF 0501.325.062 WHEEL is a critical OEM genuine component engineered for the internal planetary gear sets found in heavy-duty construction machinery transmissions. This precision-machined wheel acts as a load-bearing interface within the gear train, ensuring smooth torque transfer and rotational stability under extreme stress. Specifically designed for ZF’s powershift and hydrostatic drivelines, the SKU 0501.325.062 sits within the final drive assembly, directly engaging with the sun gear and planetary carriers. When paired with a robust 4699101043: HOUSING, this wheel maintains proper gear alignment and prevents axial play that can degrade transmission efficiency over time.

Symptoms of Failure

• Intermittent gear slipping under load: When the wheel surface wears unevenly, the planetary gears lose bite, causing sudden power loss during grading or lifting operations.
• Metallic grinding noise from the transmission housing: Worn splines on the 0501.325.062 wheel create a distinct chatter, especially when shifting from forward to reverse.
• Increased operating temperature and fluid contamination: Micro-pitting on the wheel face generates metallic debris that circulates through the hydraulic system, often requiring a replacement 0634309600: SHAFT SEAL to prevent leakage.
• Vibration in the driveline during deceleration: A fatigued wheel causes harmonic imbalance, which accelerates wear on the adjacent 4699301106: HOUSING and carrier assembly.

Technical Specifications

Compatibility

This wheel is a direct fit for ZF WG180, WG200, and WG211 series transmissions commonly used in wheel loaders, telehandlers, and excavators from manufacturers like Liebherr, Volvo, and Caterpillar. It also integrates with the ZF 4WG-200 and 6WG-200 powershift models. For proper sealing, always install a new 4699301015: HOUSING COVER and 4699301085: COVER to prevent contamination ingress during reassembly.
