Overview
The ZF 3024.301.084 FLANGE BUSH is a precision-engineered component designed for the WG 201 Series transmission. This OEM genuine part serves as a critical interface between rotating shafts and the transmission housing, reducing friction and ensuring accurate alignment under heavy torque loads. Specifically, the SKU 3024.301.084 acts as a wear-resistant bearing surface within the clutch or planetary gear assembly, preventing metal-to-metal contact that could degrade performance. It is often installed in conjunction with the 4644101160: TRANSMISSION HOUSING to maintain structural integrity, and works alongside the 4644301323: TRANSMISSION HOUSING to support shaft alignment in high-stress zones.
Symptoms of Failure
When the ZF 3024.301.084 FLANGE BUSH begins to wear, operators may notice distinct performance issues. Common failure indicators include:
- Transmission oil leaks around the flange area – Worn bushings allow pressurized fluid to escape past seals, leading to low oil levels and potential overheating.
- Gear slipping under load – Excessive clearance from a degraded bushing causes shafts to shift, resulting in intermittent power loss during acceleration.
- Unusual metallic grinding or whining noises – Direct contact between the shaft and housing creates audible friction, often worsening with RPM changes.
- Vibration in the driveline – A worn flange bushing fails to dampen rotational forces, transmitting vibrations through the transmission case.

Compatibility
This FLANGE BUSH is primarily engineered for the WG 201 Series transmission family, but it also fits select models in the WG180 and WG200 ranges due to shared shaft diameters and housing geometries. It is commonly used in ZF WG180, WG200, and WG201 gearboxes found in medium-duty trucks, buses, and off-highway vehicles. For proper installation, ensure the 4644301189: THREADED BUSH is correctly torqued, and verify that the 4475280043: SCREW PLUG is seated to prevent fluid bypass.
