Additional Information
The Chelsea 272 Series was engineered to replace and consolidate several earlier Chelsea medium-duty PTO series, including the 230, 231, 236, 238, 270, and 271. The platform offers nine speed ratios and eighteen shift configurations, making it one of the most adaptable 6-bolt hot shift PTOs for fleets running mixed equipment. The Wet-Spline option (where applicable) extends PTO and pump shaft service life by improving lubrication at the spline interface. The Smart Start option, available within the 272 Series, is designed to manage high-torque start-up conditions and reduce drivetrain shock loads. Common markets include aerial lift trucks, construction equipment, towing and recovery vehicles, water trucks, and material handling applications. Part number 272GAHVP-P5RK is also referenced as SP272GAHVP-P5RK. Not sure this is your part?
