OIL FLOW THROUGH THE M-SERIES GEAR
Here we see the steering gear in the neutral or non-
steering position. Equal low pressure is being applied
to both ends of the steering gear piston. The oil is cir-
culating at back pressure only and provides a hydraulic
cushion for the steering gear. All oil is being circulated
through the steering gear and back to the reservoir to
help cool the system.
When the steering wheel is turned, the actuating valve
is opened in one direction and all pressurized oil is
applied to one end of the steering gear piston. This
pressure build up causes the piston to move in the
Figure shows all oil being distributed to the input end
of the gear.
Figure shows all oil being distributed to the cylinder
head end of the gear.
When no input is applied through the steering wheel the gear returns to the neutral or non-steering position.
