Overview
The ZF 0730.062.262 BUSH is a precision-engineered wear component designed for the WG 65 series of heavy-duty automatic transmissions. This OEM genuine part functions as a critical bearing surface within the transmission’s rotating assembly, reducing friction between the shaft and the housing. Specifically, it supports the output shaft to maintain proper alignment and load distribution during high-torque operations. The SKU 0730.062.262 is manufactured to ZF’s original tolerances, ensuring a direct fit without modification. When installed, this bushing works in concert with the 4616105413: OUTPUT component to stabilize rotational forces and prevent metal-on-metal contact.
Symptoms of Failure
When the 0730.062.262 bushing wears beyond specification, operators will notice distinct performance issues. Look for these specific failure symptoms to diagnose a worn bushing:
- Oil leaks near the output flange: A degraded bushing allows excessive shaft movement, breaking the seal at the 4616203017: OUTPUT FLANGE, leading to visible fluid drips.
- Low-frequency vibration during acceleration: Worn clearance causes the output shaft to wobble, transmitting vibration through the 4616101117: TRANSMISSION HOUSING.
- Intermittent gear slipping under load: Misalignment from bushing wear reduces clutch pack engagement pressure, causing momentary power loss.
- Metallic debris in transmission fluid: Flaking bronze or steel particles from the bushing surface contaminate the oil, often requiring a filter change.

Compatibility
This bushing is a standard fitment for the ZF WG 65 series transmission family. Based on its dimensions and application, it is compatible with the following models: WG65, WG80, WG120, WG150, WG180, and WG200. It is also used in select off-highway and industrial drivelines where ZF’s 6-speed powershift architecture is employed. Always verify the bushing bore condition in the transmission housing before installation. The 0636011038: HEXAGON SCREW is often replaced concurrently to ensure proper clamping force on the output assembly.
