221 Series Mechanical Shift Power Take-Off

The Chelsea 221 Series Power Take-Off (PTO) is another example of why Chelsea PTO technology is the best in the business. This economical workhorse features a cast iron housing and tapered cone bearing on the output shaft, giving it a high torque rating (250 Lbs-ft) and long service life. The space saving air shift cover provides maximum clearance under the truck. The 221 has strong tapered output bearings instead of needle bearings for greater load bearing capability. The 221 Series PTO features twenty-six output options including Chelsea's popular 360° rotatable flange. Three internal speed ratios and eleven shift options, plus a self-lube option for transmissions that have problems getting lubrication to the PTO, make this one versatile PTO.
