The Chelsea 272XGAJX-P5XD is a 272 Series hot shift power take-off assembly built on a 6-bolt mounting pattern. The 272 Series consolidates several earlier medium-duty PTO lines into a single, more capable platform, supporting intermittent torque up to 300 lb-ft and continuous-duty operation with a 30% de-rate applied per application. Shift options span pneumatic and hydraulic, and the series includes an integral air control valve. Output shaft configurations within the 272 family include round shaft options with keyed drives. The 272 Series addresses demanding cycles in towing and recovery, aerial, construction, and water truck applications. Call us to confirm proper fit and shift configuration for your specific transmission.
