Overview
The ZF 4657.275.015 CLUTCH is a critical torque-transfer component engineered specifically for the WG 190 and WG 210 series transmissions. Positioned within the planetary gear set assembly, this OEM genuine part engages and disengages hydraulic pressure to manage gear shifts and power flow. The SKU 4657.275.015 ensures precise fitment and durability, directly interfacing with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain optimal hydraulic sealing and rotational stability. Without this clutch, the transmission cannot achieve proper gear engagement, making it a vital component for industrial driveline reliability.
Symptoms of Failure
When the ZF 4657.275.015 CLUTCH begins to wear, operators will notice distinct performance degradation. Common failure symptoms include:
- Delayed or harsh gear engagement – The clutch fails to lock smoothly, causing noticeable jerking during shifts, especially under load.
- Transmission oil leaks near the clutch pack – Worn seals allow hydraulic fluid to escape, leading to low pressure and erratic shifting.
- Gear slipping under acceleration – The clutch cannot hold torque, resulting in RPM flare without corresponding vehicle speed increase.
- Burning smell from overheated friction material – Slipping generates excessive heat, degrading the clutch plates and contaminating the oil.
