ZF 0501.314.799 BUSH | OEM Genuine Part

Overview

The ZF 0501.314.799 BUSH is a precision-engineered, OEM genuine wear component designed for high-stress planetary gear sets and clutch drum assemblies within heavy-duty construction machinery transmissions. This bushing acts as a sacrificial bearing surface, reducing friction between rotating shafts and stationary housings. The SKU 0501.314.799 is specifically machined to maintain tight oil clearance, ensuring proper lubrication flow to adjacent components such as the 0501211694: MOTOR and the 4108101140: HOUSING. Without this bushing, metal-on-metal contact would rapidly degrade the transmission’s internal alignment.

Symptoms of Failure

• Low hydraulic pressure and gear slipping: A worn 0501.314.799 bushing allows excessive shaft play, causing pressure loss in the clutch circuit. This often manifests as delayed engagement or slipping under load.
• Metallic debris in transmission fluid: As the bushing wears, bronze or steel particles contaminate the oil. This is a common sign that the 0735370299: TAPERED ROLLER BEARING and the bushing are both degrading.
• Abnormal whining or knocking noise: When the bushing clearance exceeds factory tolerances, the shaft vibrates against the 0501314793: COVER, producing a distinct low-frequency hum during gear shifts.
• Oil leaks from the bell housing: Worn bushings can misalign the shaft, breaking the seal at the housing interface and causing fluid to weep from the transmission case.

Technical Specifications

Compatibility

This bushing is a standard component in several ZF power-shift transmissions used in construction machinery. It is commonly found in the ZF WG180, WG200, and WG210 series. It also appears in the ZF 4WG-200 and 6WG-200 models, where it supports the output shaft inside the main housing. Always verify the bushing’s fit against the shaft journal and the 4108101140: HOUSING bore before installation.
