Overview
The ZF 2095.301.029 BUSH is a precision-engineered OEM genuine component designed to serve as a critical wear surface within the planetary gear sets of heavy-duty ZF transmissions. This bushing, identified by SKU 2095.301.029, functions as a sacrificial liner that reduces friction between rotating shafts and stationary housings, ensuring consistent torque transfer and alignment. It is commonly seated inside the 2095101024: TRANSMISSION HOUSING or the 2095301027: TRANSMISSION HOUSING, where it supports the main drive shaft under high axial and radial loads. Without this bushing, metal-on-metal contact would rapidly degrade internal assemblies, leading to costly rebuilds.
Symptoms of Failure
When the ZF 2095.301.029 bushing wears beyond tolerance, operators will notice distinct performance issues. Look for these specific failure symptoms to diagnose the problem early:
- Low hydraulic pressure at the clutch pack – Worn bushings allow excessive oil bypass, reducing engagement force and causing gear slipping under load.
- Metallic debris in transmission fluid – Flaking bronze or steel particles from the bushing contaminate the oil, often visible during routine drain intervals.
- Abnormal whining or grinding noise from the transmission housing – As the bushing clearance increases, shaft vibration creates audible chatter, particularly during deceleration.
- Oil leaks near the output shaft seal – Excessive bushing wear misaligns the shaft, damaging the seal lip and allowing fluid to escape past the 4475280150: SCREW PLUG or adjacent sealing points.

Compatibility
This bushing is a direct fit for several ZF heavy-duty transmission models commonly used in construction machinery. It is specifically designed for the WG180, WG200, and WG210 series, where it supports the input shaft or countershaft. The part also integrates with the 0634304731: O-RING to seal the bushing bore, preventing contamination. For optimal performance, always pair this bushing with a new 0634306328: O-RING and 2095301020: GASKET during installation. Use 0636011207: HEXAGON SCREW and 0636011188: HEXAGON SCREW for secure mounting to the housing.
