The Chelsea 812 Series Power Take-Off Assembly, part number 812XKAHX-A3RB or 812XKAHXA3RB, is a single-gear, 8-bolt PTO built for extra heavy-duty applications on manual transmission-equipped trucks. The cast iron, low-profile housing keeps the unit compact in tight chassis spaces, making it a practical choice for dump trucks, tow and recovery rigs, and aerial device trucks. This series uses wire/cable mechanical shift and delivers intermittent torque up to 400 lb-ft, with output power exceeding 56 HP. Chelsea's 812 Series also offered a 360-degree rotatable flange output for direct-mount pump fitment. Note that Parker Chelsea has classified the 812 Series as obsolete.
