Chelsea Products, a division of Parker Hannifin and leading power transfer solutions provider, introduced four new PTOs: 280 Series, 348 Series, 590 Series and 523 Series at the Work Truck Show 2014 in Indianapolis earlier this month.
280 Series Power-Take Off
The new 280 Series with a new P.T.O. design utilizing the best of our technology and innovations from the company's current Hot Shift P.T.O.’s. This unit is designed for the 10 Bolt P.T.O. pattern on Allison and CAT Automatic transmissions.
The 280 Series combines 277 and 278 Series into one model of P.T.O. It will feature a single continuous duty torque rating. No more intermittent rating. Pump clearance issues have been improved with rotatable cast iron flanges and the Wet Spline Pump Flange option provides 7 to 10 times greater shaft life. Broader coverage of speed ranges expands from 5 ratios to 9 ratios and includes lower and higher speeds that were never available in the past. The standard output shaft features a new positive stop for driveline outputs that eliminates the ability for shaft couplings to damage oil seals.
Three option positions for the integrated solenoid valve. Plus a remote mounted option provides maximum clearance under the truck. The pressure / lube hose will be included with the new 280 Series. No need to order separately. Versatility power ease of maintenance and installation make the new 280 Series the only choice for your vocational truck requirements.
