ZF 4681.054.001 4 WG 210 BASICPOWER Transmission Assembly | Complete Unit

Overview

The ZF 4681.054.001 4 WG 210 BASICPOWER Transmission Assembly is a complete, factory-matched unit designed for heavy-duty commercial and industrial driveline applications. This assembly serves as the central power transfer module within the ZF WG 210 series, integrating the torque converter, planetary gear sets, and hydraulic control system into a single, ready-to-install package. The SKU 4681.054.001 denotes a fully assembled BASICPOWER variant, offering reliable performance for on-highway trucks, construction equipment, and specialized off-road machinery. It sits directly between the engine bell housing and the final drive, managing gear ratio selection and torque multiplication under demanding loads.

Symptoms of Failure

When the ZF 4681.054.001 assembly begins to fail, operators often notice delayed or harsh gear engagement during startup, particularly when shifting from neutral to drive. Another common symptom is intermittent loss of power under load, where the transmission slips out of gear on inclines or during heavy acceleration. Contaminated or burnt-smelling transmission fluid frequently accompanies internal wear, indicating clutch pack degradation. Finally, unusual whining or grinding noises from the transmission housing suggest bearing or planetary gear damage, requiring immediate inspection of the complete unit.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series, but its core architecture also supports direct fitment into earlier WG 180 and WG 200 models with minor adapter modifications. It is commonly used in ZF 4WG-210, 5WG-210, and BASICPOWER variants found in municipal trucks, fire apparatus, and agricultural tractors. For proper installation, ensure the TRANSMISSION HOUSING (part 4657101078) is inspected for cracks, and verify alignment with the HOUS.FRONT SECT (part 4657201166) and the HOUSING REAR PART (part 4657201168). The HOUSING REAR SECTION (part 4657298101) is also critical for sealing the rear output flange.

Frequently Asked Questions

Q: Can the ZF 4681.054.001 be rebuilt, or is it only sold as a complete unit?
A: This SKU is a complete, pre-assembled transmission unit. While internal components like clutch discs and seals are available separately, the 4681.054.001 is designed for direct replacement to minimize downtime.

Q: What is the typical lifespan of this BASICPOWER assembly under normal operating conditions?
A: With proper maintenance and fluid changes every 500 hours, the WG 210 series typically delivers 8,000 to 12,000 hours of service life. Harsh environments or heavy towing may reduce this interval.

Q: Are the housing parts listed above interchangeable with other WG series models?
A: Yes, the TRANSMISSION HOUSING and HOUSING REAR PART are shared across WG 180, 200, and 210 series, but always verify bolt patterns and PTO openings before ordering.
