The Chelsea 871XEQTP-D3AC or 871XEQTPD3AC is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous duty operation. Nine speed ratios and thirteen output configurations give technicians broad flexibility across fire and rescue, refuse, truck crane, and pumper-cleaner installations. A ductile iron bearing cap delivers 117% greater strength compared to gray iron, and the o-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the vibrational stress common with modern engine designs. Wet Spline lubrication extends PTO and pump shaft service life. The 871 Series is the only Chelsea PTO to offer all three premium options: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
