Disassembly 

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.

NOTE: Troubleshooting information defines terms and 
problems, possible causes for problems, and recom-
mends procedures for correcting problems. 

Although not all drawings show the unit in a vise, we rec-
ommend that you keep the unit in the vise during disas-
sembly. Follow the clamping procedure explained 
throughout the manual.
