ZF 0501.314.823 BUSH | OEM Genuine Part

Overview

The ZF 0501.314.823 BUSH is a precision-engineered OEM genuine component designed to serve as a critical wear surface within the clutch pack or planetary gearset assembly of heavy-duty ZF transmissions. This bushing acts as a low-friction interface between rotating shafts and stationary housings, ensuring precise alignment and reducing metal-on-metal contact under extreme torque loads. The SKU 0501.314.823 is specifically machined to OEM tolerances to maintain proper oil film thickness, which is essential for heat dissipation and hydraulic efficiency in construction machinery drivelines. When installed alongside the 4108101140: HOUSING, this bushing provides the necessary radial support for the 0501211694: MOTOR shaft, preventing axial play that can lead to premature seal wear.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: A worn 0501.314.823 bushing allows excessive shaft movement, causing the 0501314793: COVER to misalign with the clutch drum, resulting in sluggish or harsh shifts under load.
• Low hydraulic pressure warnings: As the bushing wears, internal leakage increases past the clearance gap, reducing line pressure to the valve body and triggering diagnostic trouble codes on construction machinery dashboards.
• Metallic debris in transmission fluid: Flaking bronze or steel particles from a degraded 0501314799: BUSH (sister part) contaminate the oil, often visible during routine filter inspections or magnetic drain plug checks.
• Vibration or whining noise at specific RPM: Loss of bushing concentricity creates harmonic resonance in the gear train, particularly noticeable during cold starts or when the transmission is under heavy load in excavators and loaders.

Technical Specifications

Compatibility

This OEM bushing is a direct-fit replacement for several ZF heavy-duty transmission models commonly found in construction machinery, including the WG180, WG200, and WG210 series. It also applies to the 4WG-200 and 6WG-200 powershift variants used in wheel loaders, dozers, and graders. The bushing seats inside the 4108101140: HOUSING and interfaces directly with the 0501211694: MOTOR shaft journal. For optimal rebuild integrity, always inspect the mating 0501314793: COVER and replace the 0501314799: BUSH simultaneously to ensure uniform wear patterns across the assembly.
