The Chelsea 871LDFJW-B3TF or 871LDFJWB3TF is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. This PTO carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. The compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap is 117% stronger than gray iron. An O-ring sealing configuration between the housing and bearing cap improves clamp load and resists the vibrational stress common in modern engine designs. The 871 Series offers nine speed ratios and thirteen output options, including SAE B, SAE BB, and SAE C pump spline configurations. Wet Spline, SmartStart, and Quiet Gear options are available within the series. Call us to confirm the right configuration for your application.
