ZF 4657.054.070 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.070 4 WG 210 Powershift Transmission Assembly is a complete, ready-to-install unit engineered for heavy-duty off-highway machinery. As the core power transfer module in the WG 210 series, it integrates the torque converter, planetary gear sets, and clutch packs into a single robust assembly. The SKU 4657.054.070 serves as the direct replacement for worn or failed transmissions in loaders, dozers, and graders, ensuring seamless hydraulic engagement and precise speed control under extreme loads. This assembly sits between the engine flywheel and the final drive, converting high-torque input into smooth, shiftable output across four forward and reverse gears.

Symptoms of Failure

• Delayed or harsh gear engagement: When the internal clutch packs or valve body wear, operators experience a noticeable lag or jarring shift when moving from neutral to drive, often accompanied by a loss of hydraulic pressure.
• Transmission overheating and fluid contamination: Worn bearings or friction plates generate excessive heat, causing the oil to darken and emit a burnt smell. This is frequently paired with metallic debris found in the filter or sump.
• Intermittent power loss under load: A failing 4 WG 210 assembly may cause the machine to momentarily lose traction or speed when climbing grades or pushing heavy material, indicating internal seal failure or gear train slippage.
• External oil seepage from housing joints: Cracks or gasket degradation in the main casing lead to visible drips around the bell housing or rear cover, progressively reducing fluid levels and risking catastrophic failure.

Technical Specifications

Compatibility

This complete unit is specifically designed for the ZF WG 210 series, but it also serves as a direct upgrade or replacement for earlier WG 180 and WG 200 models in certain applications. It is commonly found in:

• ZF WG 210 (all variants including 4 WG 210)
• ZF WG 180 (with adapter modifications)
• ZF WG 200 (with torque converter matching)
• Select ZF Ergopower and Ecolife off-highway derivatives

Frequently Asked Questions

Q: Can this 4 WG 210 assembly be rebuilt, or is it only sold as a complete unit?
A: This SKU 4657.054.070 is a complete, factory-assembled unit. While internal components like the HOUS.FRONT SECT and clutch packs are serviceable, we recommend replacing the entire assembly to ensure proper alignment and warranty coverage.

Q: What is the typical lifespan of this transmission before needing replacement?
A: With proper maintenance and clean fluid, a WG 210 powershift typically lasts 8,000–12,000 operating hours. Signs of wear often appear first in the TRANSMISSION HOUSING seals and the CYLINDRICAL PIN alignment bores.

Q: Does this unit include the torque converter and oil pump?
A: Yes, the complete assembly includes the integrated torque converter, oil pump, and all internal valving. You will only need to transfer external components like the HOUSING REAR PART adapter plate if reusing your existing driveline.
