Notes:
■
Pin guide column should be aligned with the centre of connecting rod through
piston. If it is installed properly, piston guide column is just located under the centre
of the hole in tool arch arm and evenly placed on the fork piece. If wrong size of pin
guide column is used, piston and pin can't be aligned with the support.
7) Insert installer tool into support arch arm hole, and use a hydraulic press to exert
pressure to piston pin, to let it go through the small end of connecting rod. Continue to
exert pressure until the pin guide column can fall freely and installer tool is just
aligned with the top of arch arm.
Notes:
■ When installing centre shaft lining, the
pressure exerted on the arch arm should
not exceed 1250 ± 500 kg/cm
