Simson S51 - Special Tools
Professional disassembly of the engine requires some special tools.
You can buy eg. flywheel remover, which is barely a few hundred forints (about 6-800).
The other one is the block-puller. It's worth making because it's very expensive anyway.
It is very important that you do not try to screw it with a screwdriver or chisel, as it will never seal properly again.
To make it
2 threaded stem extensions,
2 pcs long M12 screws,
and also 3 long M6 screws.
The frame is made of iron plate. It should be at least 5mm thick, mine is 10mm thick.
My own plan is
downloadable from here: Simson_tool.pdf,
Thus, it can be easily redrawn because is scaled
(I found one on
the internet, unfortunately I no longer know where, but it was not
scaled when printed).
