piston ring compresser will facilitate removal. Each
piston pin is locked in place by lock rings which are
snapped into grooves in the piston wall.

terminal plate assembly need not be disturbed
unless a leak exists or a terminal part requires
replacing.

Disassemble and assemble the terminal plate as shown
in Figure 6-13.
The terminal mounting plate assembly, as originally
installed, is assembled so as to leave a small space
between the outer terminal bushing and the surface of
the mounting plate. This is to provide further crush of
the terminal bushing in case a leak should occur. To stop
a leak, tighten the terminal bushing nut only enough to
stop the escape of gas. Do not tighten until the terminal
bushing is flush with the mounting plate. The tightening
torque used at the factory is 0.21 to 0.23 mkg (18 to 20
inch pounds) maximum to prevent damage to the plastic
parts.
