(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) [67] on Plunger (A) [66], O-Rings (S-4) [62], (I.D 8.8) [61] and
(I.D 11) [64] on Valve Piston (B) [63], and the shaft of Plunger (A) [66] as shown in Fig. 19.
As shown in Fig. 19, install Valve Bushing (A) [68] so that the roll pin groove in Valve Bushing (A) [68] will be
aligned with the roll pin hole in the Body Ass'y [29]. 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 [51].
If an attempt is made to drive the roll pin with force when the roll pin groove in Valve Bushing (A) [68] is
not aligned with the roll pin hole in the Body Ass'y [29], it will damage the periphery of Valve Bushing (A)
[68] and prevent disassembly or reassembly.

Apply grease to the stem.
