Round Housing
with End Ports
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. Before disas-
sembly, drain the oil, then plug
the ports and thoroughly clean
the exterior of the SCU.
During repairs, always protect
machined surfaces.
1. Remove the plug and inlet
relief as shown in figure 1.
Note:
The manual steering
check is part of the inlet
relief valve. If inlet relief
valve is not present, the
manual steering check is
located in the housing.
2. Remove the four cap
screws and disassemble
the SCU as shown in
figure 1.
3. Slide the spool and
sleeve from the housing,
see figure 2.
4. Remove the thrust bearing
and bearing races.
5. Remove the seal.
6. Using a small blade
screwdriver, carefully pry
the dust seal from the
housing.
Important:
Do not damage
the dust seal seat.
