CHELSEA part description

Representative Image and Description - The product image above and description below applies to all Chelsea Series 278 PTOs and is not part specific. Please verify the product using the part number.

Chelsea 278 Series Power Take-Off designed for Allison and Caterpillar automatic transmissions with a 10-Bolt PTO mounting aperture. Wet Spline technology virtually eliminates spline fretting.

Quality knows quality, that’s why Allison chose Chelsea to join their engineers in developingPTOs specifically for the Allison World Transmissions. When maximum transmission clearance is needed to direct mount a pump, the Chelsea 278 Series Power Take-Off (PTO) delivers with its enhanced housing design. These electronic-over-hydraulic shift PTOs offer six speed ratios, numerous output options, and Chelsea’s SuperTorque™ gears which supply 20% higher intermittent torque ratings. The 278 Series can also be counted on for longevity due to its internal bearing lube.
Products Features:
• Wet Spline Options Available
• Cartridge Valve Assembly for reduced interference
• Enhanced housing design for maximum transmission clearance when direct mounting a pump
• Two Year Warranty
• Refuse
• Aerial
• Snow & Ice Removal
