(b) Reassembly Disassembly procedures should be followed in the reverse order. Note the following points: Be extremely careful to prevent the entry of foreign particles into the control valve section. Thoroughly apply grease to the O-ring (I.D 1.8) [69] on Plunger (A) [68], O-ring (S-4) [64], O-ring (I.D 8.8) [63] and O-ring (I.D 11) [66] on Valve Piston (B) [65], and the shaft of Plunger (A) [68] as shown in Fig. 19. As shown in Fig. 19, install Valve Bushing (A) [70] so that the roll pin groove in Valve Bushing (A) [70] will be aligned with the roll pin hole in the Body Ass'y [30]. First, insert a roll pin puller (3 mm (.118") dia.) into the roll pin hole. Then, upon confirming that the puller passes through the hole, drive in the Roll Pin D3 x 28 [54]. If an attempt is made to drive the roll pin with force when the roll pin groove in Valve Bushing (A) [70] is not aligned with the roll pin hole in the Body Ass'y [30], it will damage the periphery of Valve Bushing (A) [70] and prevent disassembly or reassembly. Body Ass'y [30] Apply grease to the stem. Coat the O-ring groove's shaft with grease.

(b) Reassembly
Disassembly procedures should be followed in the reverse order.
Note the following points:
Be extremely careful to prevent the entry of foreign particles into the control valve section.
Thoroughly apply grease to the O-ring (I.D 1.8)
[69]
on Plunger (A)
[68]
, O-ring (S-4)
[64]
, O-ring (I.D 8.8)
[63]
and O-ring (I.D 11)
[66]
on Valve Piston (B)
[65]
, and the shaft of Plunger (A)
[68]
as shown in Fig. 19.
As shown in Fig. 19, install Valve Bushing (A)
[70]
so that the roll pin groove in Valve Bushing (A)
[70]
will be
aligned with the roll pin hole in the Body Ass²y
[30]
.
First, insert a roll pin puller (3 mm (.118") dia.) into the roll
pin hole.
Then, upon confirming that the puller passes through the hole, drive in the Roll Pin D3 x 28
[54]
.
If an attempt is made to drive the roll pin with force when the roll pin groove in Valve Bushing (A)
[70]
is
not aligned with the roll pin hole in the Body Ass²y
[30]
, it will damage the periphery of Valve Bushing (A)
[70]
and prevent disassembly or reassembly.
After assembling, check that Plunger (A)
[68]
moves smoothly.
