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.

Gerotor (Meter) End

Cleanliness is extremely

important when repairing a

steering control unit. Work

in a clean area. Before dis-

connecting lines, clean port

area of unit thoroughly. Use

a wire brush to remove

foreign material and debris

from around exterior joints

of the unit.

We recommend that you

keep the unit in a vise during

disassembly. Follow the

clamping procedures

explained throughout the

manual.

Check all mating surfaces. Replace any parts that have scratches or burrs that could cause leakage. Clean all metal parts in

clean solvent. Blow dry with air. Do not wipe dry with cloth or paper towel because lint or other matter can get into the

hydraulic system and cause damage. Do not use grit paper or file or grind these parts.

Note: Lubricate all seals with clean petroleum jelly. A good service policy is to replace all old seals with new seals. Do not

use excessive lubricant on seals for meter section.

Refer to parts lists covering your steering control unit when ordering replacement parts.
