Introduction
This manual provides service
information for Char-Lynn
®
Series 5 Steering Control Units.
Step by step instructions for
complete disassembly, inspec-
tion and reassembly of the con-
trol 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 thor-
oughly 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, moisturefree
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 accura-
cy of control unit repairs on an
authorized test stand.
