Overview
The ZF 4660.306.130 PLATE is a precision-engineered component designed for the WG92 transmission series. This OEM genuine part functions as a critical separator or wear plate within the clutch pack assembly, ensuring consistent hydraulic pressure distribution and smooth gear engagement. The SKU 4660.306.130 is manufactured to ZF’s original specifications, providing exact fitment and durability under high-torque conditions. This plate sits between the transmission housing and the rotating clutch elements, directly interfacing with the 4660101023: TRANSMISSION HOUSING to maintain proper alignment and sealing.
Symptoms of Failure
- Delayed or harsh shifting: A worn 4660.306.130 plate causes uneven clutch pack pressure, leading to noticeable hesitation or jerking during gear changes.
- Transmission fluid leaks near the bell housing: Degradation of this plate compromises the seal against the 4660301058: HOUSING, resulting in external oil seepage.
- Metallic grinding noises during acceleration: Excessive plate wear allows metal-on-metal contact within the clutch stack, producing audible grinding sounds under load.
- Burning smell from overheated fluid: Slipping caused by a warped plate generates friction heat, oxidizing the transmission oil and emitting a distinct burnt odor.
