Implement Pump Changed {5057,5070}
Usage:
Challenger 65E (6GS),
Challenger 75E (6HS),
Challenger 85E (6JS),
Challenger 95E (6KS) Agricultural Tractors
Description of Change: The hydraulic implement pump has been changed. The implement pump is now common with the Rowcrop Tractors. The pump has improved shaft seal retention and better cold weather operation during startup, as compared to the previous pump design.
NOTE: The pump group part numbers between Tillage and Rowcrop Tractors are different due to direction of rotation.
Adaptable To: The improved 158-0522 Pump Group and associated lines group changes were effective with Challenger 65E (6GS516), Challenger 75E (6HS497), Challenger 85E (6JS534), and Challenger 95E (6KS724) Agricultural Tractors.
