Disassembly
DISASSEMBLY
Cleanliness is extremely important when repairing
hydraulic Steering Control Units (SCU). Work in a clean
area. Before disconnecting the hydraulic lines, clean the
port area of the SCU and tag the hoses for proper instal-
lation. Before disassembly, drain the oil, then plug the
ports and thoroughly clean the exterior of the SCU.
During repairs, always protect machined surfaces.
