Table of Contents
This manual provides service
information for Char-Lynn
®
Series 10 VersaSteer™
Steering Control Units. Step
by step instructions for
complete disassembly,
inspection and
reassembly of the control
unit are given.
The following
recommendations should be
followed to insure
successful repairs.
•
Most repairs require the
removal of the control
unit from the vehicle.
•
Cleanliness is extremely
important.
•
Clean the port areas
thoroughly before
disconnecting the
hydraulic lines.
•
Plug the control unit
ports and cover open
hydraulic lines
immediately after they
have been
disconnected.
•
Drain the oil and clean
the exterior of the
control unit before
making repairs.
•
Wash all metal parts in
clean solvent.
•
Use filtered, moisture-
free compressed air to
dry the parts.
Do not wipe them dry
with paper towels or
cloth – lint in a hydraulic
system will cause
damage.
•
Always use new seals
when reassembling
hydraulic control units.
•
Lubricate new rubber
seals with a petroleum
jelly before installation.
•
Torque all bolts over
gasketed joints, then
repeat the torquing
sequence to make up for
gasket compression.
After all repairs are
complete it is essential to
verify the accuracy of control
unit repairs on an
authorized test stand.
