The Chelsea 267XMFJW-M3RY or 267XMFJWM3RY is a 267 Series Power Take-Off built on a 10-bolt mounting pattern for Allison automatic transmissions. It operates as a constant mesh PTO, making it a practical fit for load-sensing hydraulic pump applications such as yard jockey trucks, small refuse trucks, and snow and ice equipment. The output shaft is a 1-1/4" round shaft with keyway. Shaft power ratings for this series are 32 HP at 500 RPM and 64 HP at 1,000 RPM, with intermittent torque up to 335 lb-ft (check application pages for actual torque ratings specific to your configuration). Pro Gear and Transmission stocks genuine Chelsea product. Call us to confirm proper fit for your application.
The Chelsea 267 Series is available with the SuperTorque option, which provides up to 20% greater torque capacity than a standard 267 Series configuration. Continuous operation is possible with a 30% de-rating applied. Multiple output flange types are available across the 267 Series, including SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs. The 267 Series is offered in five speed ratios. Refer to Chelsea application pages to confirm the correct ratio, output type, and torque rating for your specific installation.
