installer and detacher. When installing or dismantling pin, piston is clamped in the
support. When installing or dismantling, guider helps to fix piston pin. At this
moment, connecting rod is clamped by the fork piece.

When the connecting rod is fixed on the
fork piece, put piston into the support.
Detaching tool goes through the top of
the support. This can be used to press
piston pin out.

connecting rod.
6) Fix connecting rod inside piston. Insert proper pin column from the side of piston
