Parker Chelsea has introduced the new 892 series PTO, designed to make hydraulic pump installation simpler in oil field exploration and maintenance trucks. According to Parker, the 892 series provides maximum clearance for 4700 series transmissions and includes a wet spline system that lubricates the mating PTO and pump shafts. The wet spline system is said to increase the life of these components by seven to 10 times over a dry mating connection.
The 892 series also features six speed ratios, eight output types and six shift options, which are said to provide flexibility.
