Disassembly
Cleanliness is extremely important when repairing a
steering control unit. Work in a clean area. Before
disconnecting lines, clean port area of unit thoroughly.
Use a wire brush to remove foreign material and debris
from around exterior joints of the unit. Although not all drawings show the unit in a vise, it is
recommended that you keep the unit in the vise during
disassembly. Follow the clamping procedures explained
in the instructions.
