It mounts via an 8-bolt pattern and accepts pneumatic or PowerShift (pneumatic/hydraulic) actuation with an integral air valve. The 1-1/4" round output shaft uses a 5/16" key and is compatible with transmissions from Allison, Eaton/Fuller, Volvo/Mack, and select other manufacturers. Intermittent torque capacity reaches 201-300 lb-ft (401-500 Nm), with a continuous torque rating up to 300 lb-ft. Shaft power output is 29 HP at 500 RPM and 57 HP at 1000 RPM. The 282 Series includes a Wet-Spline option for extended PTO and pump shaft life, plus a Smart Start option for high-torque startups. Call us to confirm proper fit for your application.
