ZF 5838.300.039 BUSH | OEM Genuine Part

Overview

The ZF 5838.300.039 BUSH is a precision-engineered OEM genuine component designed to reduce friction and maintain accurate shaft alignment within heavy-duty ZF powershift transmissions. Positioned as a critical wear surface inside the transmission housing, this bushing supports rotating shafts and absorbs radial loads during high-torque operations in construction machinery. The SKU 5838.300.039 is manufactured to strict OEM tolerances, ensuring a proper interference fit and long service life under extreme loads. When this bushing wears, it compromises the entire drivetrain assembly, making timely replacement essential for maintaining transmission integrity.

Symptoms of Failure

• Transmission oil leaks around the shaft seal area – A worn 5838.300.039 bushing allows excessive shaft movement, breaking the seal and causing fluid seepage.
• Gear slipping under load or during acceleration – Bushing wear creates clearance that misaligns gear sets, leading to intermittent power loss and harsh shifting.
• Abnormal metallic grinding or whining noise from the transmission – As the bushing surface degrades, metal-to-metal contact generates audible noise, especially at low speeds.
• Vibration in the driveline during operation – Excessive radial play from a worn bushing transmits vibration through the transmission case and into the chassis.

Technical Specifications

Compatibility

This OEM bushing is specifically designed for ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, dozers, and excavators. It also fits select ZF 4WG-200 and 6WG-200 models used in construction machinery. For proper installation, always verify the shaft diameter and housing bore dimensions against your transmission’s service manual.

Related Components

When replacing the 5838.300.039 bushing, inspect these companion parts in the same assembly. The 5838109007 DIFFERENTIAL and 2095209019 DIFFERENTIAL share the same housing and can develop wear simultaneously. The 0750117075 TAPER ROLLER BEARING supports adjacent shaft loads, while the 0631329086 SPRING PIN secures alignment components. Replacing these parts together prevents premature bushing failure.
