Parker Chelsea makes power take-off (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 with this in mind to provide maximum clearance for the 4000-4500 Series 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 seven to 10 times longer than a dry mating connection.
The 891 features six speed ratios, seven output types, and six shift options to provide the greatest flexibility for applications. Visit www.parker.com for more information.
