Overview
The ZF 4657.172.031 CLUTCH is a critical friction component engineered specifically for the WG 190 and WG 210 transmission series. This OEM genuine part serves as the primary torque-transfer interface within the planetary gear set, engaging and disengaging hydraulic pressure to facilitate smooth gear shifts. As a direct replacement for the WG 211 Series, the SKU 4657.172.031 ensures precise alignment with the transmission’s internal drum assembly. When paired with the 4657120005: PRESSURE REGULATOR, this clutch maintains consistent hydraulic clamping force, preventing slippage under heavy load conditions.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn 4657.172.031 clutch pack causes noticeable hesitation when shifting from neutral to drive, often accompanied by a jarring thud.
- Transmission fluid overheating: Slipping friction surfaces generate excessive heat, leading to burnt-smelling ATF and potential thermal damage to the 0501211384: VALVE body.
- Intermittent loss of forward or reverse drive: As the clutch material degrades, hydraulic pressure bleeds past the seals, causing intermittent power loss under acceleration.
- Visible clutch debris in the oil pan: Metallic or friction material particles in the fluid indicate the 4657.172.031 clutch plates are disintegrating.

Compatibility
This clutch is designed for ZF WG-series transmissions, including the WG 180, WG 190, WG 200, and WG 210 models. It is a direct fit for the WG 211 Series category. The 4657.172.031 works in conjunction with the 0630532183: INDENTED RING to secure the clutch pack within the drum, while the 4656306145: PISTON applies hydraulic force to engage the clutch. Always verify your transmission’s serial number before ordering.

Frequently Asked Questions
Q: Can I install the 4657.172.031 clutch without replacing the piston?
A: It is strongly recommended to replace the 4656306145: PISTON simultaneously, as worn piston seals can cause premature clutch failure due to uneven pressure application.
Q: What is the expected service life of this clutch in a WG 210 transmission?
A: Under normal operating conditions with proper fluid maintenance, the 4657.172.031 typically lasts 200,000 to 300,000 miles. Overheating or contamination will drastically reduce this lifespan.
Q: Does this part include the indented ring?
A: No, the 0630532183: INDENTED RING is sold separately. You must order it to complete the clutch pack installation.
