Overview
The ZF 4657.176.023 CLUTCH is a critical torque-transfer component engineered specifically for the WG 190 and WG 210 series transmissions. This OEM genuine part sits within the planetary gear set assembly, where it engages and disengages power flow between the input shaft and the gear train. As a friction-based coupling element, the 4657.176.023 clutch ensures smooth gear shifts and reliable power delivery under heavy industrial loads. This SKU is precision-machined to ZF’s original tolerances, guaranteeing a direct fit and long service life when paired with its surrounding assembly components such as the 4657101049: TRANSMISSION HOUSING and the 4657301130: HOUS.FRONT SECT.
Symptoms of Failure
When the ZF 4657.176.023 clutch begins to wear, operators often notice delayed engagement or gear slipping under load—a common long-tail search query for WG 190 transmission issues. Another frequent symptom is erratic shifting or harsh engagement, where the transmission jerks or hesitates between gears. You may also detect dark, burnt-smelling transmission fluid caused by excessive friction material shedding from the clutch plates. Finally, intermittent loss of drive in forward or reverse can occur, particularly when the clutch pack fails to hold pressure, leading to costly downtime if not addressed promptly.

Frequently Asked Questions
Q: Can the 4657.176.023 clutch be used in a WG 210 transmission with a modified valve body?
A: Yes, this OEM clutch is compatible with standard and modified valve bodies, provided the hydraulic pressure does not exceed 14 bar. Always verify piston clearance after installation.
Q: What is the typical lifespan of this clutch under heavy-duty cycles?
A: In normal industrial use with proper fluid maintenance, the 4657.176.023 clutch typically lasts 3,000–5,000 operating hours. Frequent full-load shifts may reduce this interval.
Q: Do I need to replace the CYLINDRICAL PIN (0631306816) when installing this clutch?
A: While the pin is reusable if undamaged, we recommend replacing it with a new 0631306816: CYLINDRICAL PIN to ensure precise housing alignment and prevent oil leaks.
