The Chelsea 221RCAJP-V3RA or 221RCAJPV3RA is a 221 Series Power Take-Off from Parker Chelsea, designed for low-speed, heavy-duty service on vocational trucks including dump, tow, and aerial applications. The 221 Series mounts with a 6-bolt pattern and supports wire/cable or mechanical shift. Output options across the series include SAE A, SAE B, ISO 7652 pump flanges, and driveline configurations, with tapered cone output bearings for greater load capacity than needle-bearing designs. The series carries an intermittent torque rating of 250 lb-ft and is compatible with Allison, Eaton/Fuller, Volvo/Mack, and other transmission families. The cast iron housing includes a space-saving air shift cover for clearance under the truck. Call us to confirm proper fit for your application.
