Reassembly of the control valve section
(2) Reassembly
Conduct reassembly by reversing the disassembly procedure, but note the following:
(a) Reassembly of the control valve section
•
Always keep the control valve section clean.
•
Fully apply grease to the O-Ring (S-16)
[96]
, O-Ring (1AP-5)
[99]
and O-Ring (S-6)
[100]
of Valve
Bushing (A)
[101]
, O-Ring (I.D 1.8)
[92]
of the Plunger
[93]
, O-Ring (P7-U)
[98]
, O-Ring (P9-U)
[88]
and O-Ring (1AP-11)
[90]
of the Valve Piston
[89],
and O-Ring (S-14)
[95]
and O-Ring (S-16)
[96]
of
Valve Bushing (B)
[97]
.
•
Match the concave portion of Valve Bushing (A)
[101]
with that of Valve Bushing (B)
[97]
as shown
below, and then insert the two Pins D2 x 8
[94]
into both. For reassembly on the Body Ass'y
[39]
,
first insert the roll pin puller (ø 3) by making sure the pin passes through the roll pinhole, and then
hammer in the two Roll Pins D3 x 28
[65]
. Orient the splitting of Roll Pin D3 x 28
[65]
as shown below
at reassembly.
NOTE: Always match the roll pin groove of Valve Bushing (A) [101] with the roll pinhole of the
Body Ass'y [39] before hammering in the roll pin. Otherwise, the periphery of Valve
Bushing (A) [101] will be damaged, thereby inhibiting disassembly and reassembly of
the control valve section.
•
After reassembly, make sure that the Plunger
[93]
moves smoothly.
