Overview
The ZF 4657.055.316 5 WG 210 Powershift Transmission Assembly is a complete, factory-grade unit engineered for heavy-duty off-highway machinery. This assembly integrates the main gear cluster, clutch packs, and hydraulic control components into a single, ready-to-install package. As a direct replacement for the WG 210 series, it restores full power flow from the torque converter to the output shaft. The SKU 4657.055.316 is precision-machined to OEM tolerances, ensuring seamless integration with existing driveline systems. When installing this unit, always pair it with a new 0634313603: O-RING to guarantee a leak-free seal at the housing interface.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn clutch discs within the assembly cause hesitation when shifting from neutral to forward or reverse, often accompanied by a jarring thud.
- Internal hydraulic pressure loss: Cracks in the housing or degraded seals lead to low system pressure, resulting in sluggish operation under load and eventual transmission slippage.
- Contaminated transmission fluid: Metal debris from failing bearings or gear teeth circulates through the oil, causing dark, gritty fluid and erratic shifting patterns.
- External oil seepage at mating surfaces: Deteriorated gaskets around the front section allow fluid to weep, leaving visible drips on the bell housing and undercarriage.
