10. With a straight-bladed screwdriver, vent
reservoir by removing filler plug, indicated at
E, Fig. 16-121; then reinstall plug.
NOTE: Venting the reservoir is necessary
in this "sealed-in" unit to equalize air pres-
sure in reservoir to that of the atmosphere.
This operation prevents the possibility of hy-
draulic fluid being forced under pressure from
disconnected lines and causing damage to trim
or body finish.
11. Disconnect hydraulic lines at F, Fig. 16-
121, and cap open fittings to prevent leakage of
fluid. Use a cloth to absorb any leaking fluid,
then remove unit from rear compartment.
b. Disassembly
Disassembly of pump and motor assembly is
limited to those parts illustrated in Fig. 16-122.
1. Remove motor and pump assembly from
body.
2. Scribe a line across pump end plate, reser-
voir tube and reservoir tube end plate, as shown
in Fig. 16-123, to insure a correct assembly of
parts.
3. With a straight-bladed screwdriver, remove
reservoir filler plug. Note sealing ring around
Plug.
4. Drain fluid from reservoir into a clean con-
tainer.
5. With suitable tool remove bolt from end of
assembly and remove reservoir end plate and
tube. Note sealing rings around bolt, reservoir
end plate, and between end of reservoir tube and
pump cover plate assembly.
c. Assembly
