The Challenger MT455D, MT465D, MT475D Tractor Manual Extract
High-pressure system, high flow rate
The high-pressure system, high flow rate is supplied via a pump 19 cm³ (1.16 in³) fitted to the internal face of the right-hand cover plate.
The pump 19 cm³ (1.16 in³) supplies, in the following order:
– The trailer brake spool valve (1) which is priority (if fitted)
– The front axle suspension (via a priority valve) – The high-pressure braking system (via a priority valve)
– The auxiliary spool valves

– The linkage valve on the left-hand cover plate A safety valve (2), set to 200 bar (2901 psi), is fitted in the delivery channel on the right-hand cover plate to protect the high-pressure system.

Oil not used by the priority systems supplies the auxiliary spool valves fitted at the back of the linkage cover plate.
Starting at the auxiliary spool valves, a line supplies the linkage spool valve located on the left-hand hydraulic cover plate.
Excess flow from the high flow rate – high-pressure system returns to the pump inlet manifold without passing through the 150-micron filter (3).

When the tractor is fitted with a suspended front axle or a high-pressure braking system, a priority unit (4) is fitted to the right-hand cover plate. This supplies the front suspension or the braking system as required. This unit has a flow limiter controlled via a load sensing line.
