Stadion Piston Pin Installation Tool
The piston rests against the recess in the tool, and the protruding part of the tool is aligned with the piston pin bore. A threaded rod is then inserted and used to press the piston pin into the piston. The tool ensures that the piston pin remains perpendicular to the piston and prevents it from getting misaligned or jammed during installation.
More details on my YouTube channel.
Designed for pistons with a 10 mm piston pin diameter. The recess has a 40 mm diameter, making the tool suitable for pistons with a diameter of approximately 38–40 mm.
Crankcase splitter (magneto side)
Note: Be careful and do not use excessive force. The tool is secured in the crankcase by only two M4 screws, and after many years the thread condition may no longer be ideal.
I always preloaded the puller first and then struck the main screw with a hammer. This moved the crankshaft slightly. I repeated the process until the entire shaft came out.
Crankcase splitter (clutch side)
It can also be used to make installation and removal of the clutch pressure plate cover easier.
