The Chelsea 272 Series Power Take-Off Assembly, part number 272HKLLP-B8BD or 272HKLLPB8BD, is a 6-bolt hot shift PTO designed for medium-duty mobile equipment applications. The 272 Series supports up to 300 lb-ft of intermittent torque and is available with hydraulic or pneumatic shift options, including an integral air control valve. Nine speed ratios and eighteen shift configurations make this series highly adaptable across aerial, construction, towing and recovery, and water truck applications. Direct-mount outputs offer an optional Wet-Spline design for extended service life, and driveshaft outputs include Smart-Start capability for high-torque engagement conditions.
