221REAJP-V3RA Chelsea PTO Assembly

The Chelsea 221REAJP-V3RA or 221REAJPV3RA is a 6-bolt, wire/cable mechanical-shift power take-off from the Chelsea 221 Series, built around a cast iron housing with tapered cone output bearings for greater load capacity than needle-bearing designs. The output shaft is a 1-1/4" round with keyway. Intermittent torque rating for the 221 Series runs up to 250 lb-ft (check application pages for actual ratings on this configuration). Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmission families include Allison, Eaton/Fuller, Volvo/Mack, and Hino. Greaseable pump shafts reduce spline fretting and corrosion during heavy-duty, low-speed service. Available with a standard or low-profile housing to suit tight cab clearances. Call us to confirm proper fit for your transmission and application.
