10-2. Disassembly and Reassembly of the Output Section
(1) Piston [10], Cylinder [14] and the related parts
Tool required:
Hexagonal bar wrench (4 mm)
(a) Disassembly (See Figs. 8, 9 and 10.)
Remove the four Hex. Socket Hd. Bolts M5 x 20 [3], and take off the Exhaust Cover [4]. The Piston [10]
can then be taken out.
Next, as illustrated in Fig. 9, screw two of the previously removed Hex. Socket Hd. Bolts M5 x 20 [3] into the
provided holes on the Cylinder Plate [13].
Gripping these two bolts, simultaneously turn and pull upward to remove the Cylinder Plate [13]. When this
has been accomplished, the Cylinder [14] and other parts which make up the output section can be
removed, as illustrated in Fig. 10.
If it is difficult to remove the Cylinder [14], remove the Nose [26] by referring para. 10-2-(3) procedures, and
push out the Cylinder [14] from the lower part of the main body.
(b) Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to the following items.
Reassembly of the Piston [10] can be most easily accomplished by inserting the Piston [10] into the
Cylinder [14] as illustrated in Fig. 11, and insertng the Piston [10] into the grooves on the Nose [26] while
pulling the piston out in a downward direction.
When assembling Gasket (B) [5], ensure that its air vents are properly aligned with the air vents on Body
Ass'y [21].
Tighten the four Hex. Socket Hd. Bolts M5 x 20 [3] to specified torque (85
There is no directivity of Piston [10] in the assembly of Piston [10].
