Steering hydraulic system
CLG835H
Priority valve
Main technical parameters
No automatic return
to the neutral posi-
tion of steering
wheel
When the pressure drop in the neu-
tral position increases and steering
wheel stops turning, the metering
pump is not unloaded (vehicle off
tracking occurs)
Steering column axially abuts
the spool to the bottom
Troubleshooting in accor-
dance with specific condi-
tions
High resistance of steering
column
Leaf spring break
The installation of steering
column is not concentric to
that of spool
No steering to the
extreme position
No steering of steering cylinder to
the extreme position, steering is
heavy as reflected
Low pressure of safety valve
Increase the pressure of
safety valve properly
No manual steering
During power steering, the cylinder
piston moves to the extreme posi-
tion, the driver does not have obvi-
ous feel of end point; during manual
steering, the steering wheel rotates
but the cylinder is still
Large radial or axial clearance
of stator and rotor pair
Replace the stator and
rotor pair
