Parker Chelsea's 891 Series PTO Cuts Installation Time
The new 891 Series PTO from Parker Chelsea is said to make PTO and pump installation simpler and more reliable on oil field exploration and maintenance trucks

The new 891 Series PTO from Parker Chelsea is said to make PTO and pump installation simpler and more reliable on oil field exploration and maintenance trucks.
Because of the large physical size of the pumps used on these applications clearance has always been a challenge. Chelsea's new 891 Series was designed to provide maximum clearance for the 4000 - 4500 Series Allison transmissions with the oil cooler option.
Another challenge is the torsional vibrations from today's diesel engines that prematurely wear out mating PTO and pump splines. The Wet Spline System that lubricates the mating PTO and pump shafts will increase the life of these components 7 to 10 times longer than a dry mating connection, the company says.
The 891 features 6 speed ratios, 7 output types and 6 shift options to provide you with the greatest flexibility for your application.
