(a) Disassembly (See Fig. 10.)
Loosen the four Hex. Socket Hd. Bolts M5 x 35 [2], and
remove the Exhaust Cover [4]. The Piston [12], Cylinder [16],
Piston Bumper [17] and related parts that make up the output
section can then be taken out.
As the Top Cover [1] is press-fitted into the groove at the upper
part of the Exhaust Cover [4], it can be removed by inserting
an appropriate rod into the exhaust port.
As the Cylinder Packing [13] is fitted into the groove of the
Cylinder [16] by a pliable rubber fit, simply bend the rubber
enough to slide over the side of the groove so that it can be
taken out.
(b) Reassembly
Reassembly can be accomplished by following the
disassembly procedures in reverse. However, particular
attention should be given to the following points.
When reassembling Cylinder Washer (A) [14] and Cylinder
Packing [13] onto the Cylinder [16], assemble them so that the
curved portion of Cylinder Washer (A) [14] is on the Piston
Bumper [17] side.
