ZF 4657.054.145 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.145 4 WG 210 Powershift Transmission Assembly is a complete, ready-to-install unit engineered for heavy-duty industrial applications. As a core component of the WG 210 Series, this assembly integrates the main gear set, clutch packs, and hydraulic control system into a single, sealed housing. The SKU 4657.054.145 replaces worn or failed transmissions in loaders, dozers, and material handlers, restoring full power flow from the torque converter to the output shaft. It is designed to bolt directly into the chassis, mating with the engine bellhousing and driveline components.

Symptoms of Failure

• Delayed or harsh gear engagement: When the internal clutch packs or seals degrade, operators experience a noticeable lag or jarring shift between forward and reverse ranges, often accompanied by a loss of hydraulic pressure.
• Transmission slipping under load: Worn friction discs or damaged planetary gears cause the unit to lose torque during heavy lifting or climbing, resulting in engine revving without proportional vehicle movement.
• External oil leaks at housing seams: Cracks or gasket failures in the TRANSMISSION HOUSING or HOUS.FRONT SECT allow transmission fluid to escape, leading to low oil levels and eventual overheating.
• Unusual whining or grinding noises: Bearing failure or debris contamination inside the HOUSING REAR PART produces metallic sounds during operation, indicating imminent internal damage.

Technical Specifications

Compatibility

This complete assembly is specifically designed for the ZF WG 210 series of powershift transmissions. It is directly compatible with WG 210 models used in mid-size wheel loaders and telehandlers. Based on its housing architecture and gear ratios, it may also be retrofitted into earlier WG 180 and WG 200 series applications with minor modifications to the HOUS.FRONT SECT and HOUSING REAR PART. Always verify spline counts and bellhousing patterns before installation.

Frequently Asked Questions

Q: Can the ZF 4657.054.145 be installed without replacing the housing sections?
A: It is strongly recommended to inspect and, if necessary, replace the TRANSMISSION HOUSING and HOUS.FRONT SECT during a full assembly swap to prevent hidden cracks or wear from causing premature failure.

Q: What is the typical service life of this complete unit?
A: Under normal operating conditions with proper fluid maintenance, the 4 WG 210 assembly can last 8,000–12,000 hours. Early symptoms like slipping or leaks indicate the need for immediate replacement.

Q: Are the filter screens included with this assembly?
A: No, the SCREEN SHEET (4657301032) and SCREEN SHEET (4657301033) are sold separately but are critical for protecting the new transmission from debris.
