Overview
The ZF 2095.340.002 BUSH is a precision-engineered OEM genuine component designed to function as a critical wear surface within the planetary gear sets of heavy-duty ZF transmissions. This bushing reduces friction between rotating shafts and stationary housings, ensuring smooth power transfer under extreme loads. As an OEM part, the SKU 2095.340.002 guarantees exact dimensional tolerances and material composition required for long service life in construction machinery applications. It is typically located in the transmission’s output section, where it supports the differential assembly and manages radial loads during high-torque operations.
Symptoms of Failure
When the ZF 2095.340.002 bushing wears beyond specification, operators may notice low-frequency humming from the transmission housing during acceleration. A second common failure sign is intermittent gear engagement difficulty, particularly when shifting between forward and reverse. Advanced wear often produces metallic debris in the transmission oil filter, indicating the bushing’s bronze or steel lining has begun to disintegrate. Finally, excessive axial play at the output flange can be measured during routine maintenance, which directly compromises driveline alignment and accelerates wear on adjacent components.

Compatibility
This bushing is engineered for ZF’s WG series transmissions, specifically the WG180, WG200, and WG250 models commonly found in wheel loaders, graders, and compactors. It also fits select ZF 4WG-310 and 5WG-400 units used in larger construction machinery. Always verify the part number against your transmission’s serial plate before installation, as bushing dimensions vary between early and late production runs.

Frequently Asked Questions
Q: How do I know if the 2095.340.002 bushing is the correct replacement for my ZF transmission?
A: Cross-reference your transmission model (e.g., WG180, WG200) with the part number stamped on the old bushing. If the inner diameter measures 45.0 mm and the outer diameter is 55.0 mm, this OEM bushing is a direct fit.
Q: Can I reuse the old bushing if it shows only minor scoring?
A: No. ZF specifies that any visible wear on the bushing’s bearing surface requires replacement. Reusing a worn bushing accelerates damage to the taper roller bearing and differential housing.
Q: What tools are needed to install this bushing?
A: A bushing driver set and a press are recommended. Never hammer the bushing directly, as this can distort the bore and cause premature failure of the diff.housing.
