ZF 4657.054.319 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.319 4 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway applications. As the core power transfer module in the WG 210 series, it integrates the torque converter, planetary gear sets, and hydraulic clutch packs into a single sealed assembly. The SKU 4657.054.319 replaces worn or failed transmissions in wheel loaders, graders, and industrial tractors, restoring full forward/reverse shuttle capability and load-sensing hydraulic response. This complete unit eliminates the need to rebuild individual subassemblies, reducing downtime during major overhauls.

Symptoms of Failure

• Delayed engagement or gear slipping under load: When the internal clutch packs wear, operators experience a lag between shifting and actual gear engagement, especially when reversing direction under heavy bucket loads.
• External oil leaks near the housing seam: Cracks or gasket failures in the TRANSMISSION HOUSING or HOUS.FRONT SECT allow transmission fluid to escape, leading to low pressure and eventual clutch burn.
• Erratic shifting or transmission shudder: Worn valve body components or damaged HOUSING REAR PART bores cause pressure fluctuations, resulting in harsh or unpredictable gear changes during operation.
• Metal debris in the oil pan: Advanced wear of planetary gears or bearings generates metallic particles, often originating from a cracked HOUSING REAR SECTION, indicating imminent internal failure.

Technical Specifications

Compatibility

This complete unit is engineered for the ZF WG 210 series powershift transmissions. It is directly compatible with WG 210 models used in 6-8 ton wheel loaders and graders. While primarily designed for the WG 210, the assembly shares mounting patterns and hydraulic interfaces with the WG 180 and WG 200 series, though internal gear ratios may differ. Always verify the housing casting numbers against your existing TRANSMISSION HOUSING to confirm fitment before installation.

Frequently Asked Questions

Q: Can this complete unit be installed without replacing the housing sections?
A: Yes, the ZF 4657.054.319 is a fully assembled transmission. However, if your existing TRANSMISSION HOUSING shows cracks or wear, we recommend replacing it simultaneously to avoid future leaks.

Q: What is the typical service life of this assembly in a wheel loader?
A: Under normal operating conditions with proper maintenance, this WG 210 unit typically delivers 8,000 to 12,000 hours before requiring a rebuild. Symptoms like slipping or debris in the oil indicate it is time for replacement.

Q: Are the screen sheets and cap screws included with the complete unit?
A: No, the complete assembly includes the main housing, gear train, and clutches. Items like the SCREEN SHEET and CAP SCREW are sold separately to allow you to replace wear items during installation.
