The Chelsea 267SGFJP-M5XX or 267SGFJPM5XX is a 10-bolt, constant mesh Power Take-Off Assembly from the Chelsea 267 Series, engineered specifically for Allison automatic transmissions. It delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an intermittent torque rating in the 301-400 lb-ft range (check application pages for your specific configuration). The output shaft is a 1-1/4" round shaft with keyway. This series suits variable-displacement piston pump applications on yard jockey trucks, small refuse trucks, and snow and ice equipment. Rotatable flanges allow clearance adjustments, and wet spline or greaseable shaft options help extend service life on both the PTO and pump shaft. Call us to confirm proper fit for your transmission and application.
The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including SAE B, SAE C, and ISO 7652 pump flanges as well as driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Continuous operation is supported with a 30% de-rating applied. Typical applications include yard jockey trucks, small refuse trucks, and snow and ice removal equipment.
