281GCFJP-D3AC Chelsea PTO Assembly

The Chelsea 281GCFJP-D3AC or 281GCFJPD3AC is a 281 Series hydraulically shifted hot-shift power take-off built for automatic transmissions with a 10-bolt aperture, including Allison applications. It mounts via a 10-bolt flange and offers nine speed ratios spanning low and high ranges. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibrational effects. The clutch pack features steel discs 80% thicker than the previous generation to resist premature tooth wear. Rotatable cast-iron flanges reduce interference fitment issues, and the Wet Spline Lubrication option extends shaft life by 7 to 10 times. SmartStart reduces shock load at engagement, and the Electronic Overspeed Control (EOC) safeguards driven equipment. A genuine Chelsea part from Pro Gear and Transmission.
