C-300N/C-500N HYDRAULIC POWER STEERING GEAR
SD-30-4265
POWER STEERING GEAR
DESCRIPTION
The Compact 300N and 500N (C-300N/C-500N), Hydraulic
Power Steering Gears are designed for medium and heavy
duty vehicles with front axle weight ratings of 6,000 to 9,000
lbs for the C-300N and up to 15,000 lbs for the C-500N.
They are integral power steering gears incorporating the
mechanical and hydraulic actuation and control components
in a single cast housing which serves as the power cylinder.
The C-300N and C-500N power steering gears are very similar
in appearance with the major difference being that the C-
500N is proportionately larger than the C-300N.
The vehicle’s steering column is coupled to the gear at the
input shaft which transmits steering effort through a
recirculating ball screw (spindle assembly) and piston. The
piston is an integral part of the power assist and also acts
as a steering damper. The direction and degree of power
assist is controlled by a rotary hydraulic valve which is integral
to the input shaft and spindle assembly. An engine driven
hydraulic pump supplies the flow and pressure.
