ZF 4657.065.002 5 WG 211 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4657.065.002 5 WG 211 Powershift Transmission Assembly | Complete Unit is a fully assembled, drop-in ready gearbox core designed for heavy-duty industrial and agricultural machinery. This complete unit integrates the main drive housing, clutch packs, and planetary gear sets into a single, pre-tested assembly. As the central power transfer component, it sits between the engine and the driveline, managing torque distribution across five forward speeds. The SKU 4657.065.002 is a direct OEM replacement for the WG 211 series, ensuring precise fitment without modification. For a full rebuild, pair this assembly with a new 4657101049: TRANSMISSION HOUSING to guarantee structural integrity.

Symptoms of Failure

• Erratic gear engagement or slipping under load: Worn clutch discs or valve body wear inside the assembly cause delayed shifts or complete loss of drive, especially in reverse.
• External oil leaks at housing seams: Cracks or gasket failure in the main casing lead to fluid loss, often visible near the 4657301130: HOUS.FRONT SECT or rear cover.
• Unusual grinding or whining noises: Bearing fatigue or gear tooth damage within the assembly produces metallic sounds during acceleration or deceleration.
• Overheating transmission fluid: Internal friction from worn components generates excessive heat, triggering warning lights or burnt oil smell.

Technical Specifications

Compatibility

This complete unit is engineered for the ZF WG 211 series, but its core architecture is shared across the WG family. It directly replaces units in WG 180, WG 200, and WG 210 transmissions used in telehandlers, wheel loaders, and tractors. The assembly also fits select ZF 4WG-200 and 5WG-210 variants with minor adapter plate changes. Always verify the bellhousing pattern against your existing 4657301131: HOUSING REAR PART to confirm compatibility.
