Usage:
Challenger 35 (8DN),
Challenger 45 (1DR),
Challenger 55 (7DM) Agricultural Tractors
Description of Change: New quick couplers are being used on the hydraulic valve groups. The new coupler components reduce leakage, keep the coupler cleaner, and require lower coupling and uncoupling forces.
Adaptable To: The new quick couplers are effective with Challenger 35 (8DN0544), Challenger 45 (1DR1093), and Challenger 55 (7DM1) Agricultural Tractors. The new quick couplers are adaptable to all earlier Challenger 35, and Challenger 45 Agricultural Tractors.
The following chart shows the new serviceable part numbers and the quantities required for the couplers used in each of the groups.
See the following illustrations for part locations.
Implement quick couplers.
