MAMOD PISTON CYLINDER ASSEMBLY TE1A SR1A SW1A SA1 MM2 SP2 SP3 MEC1
This is the Mamod Standard Piston and Cylinder
You can see from the photos that Mamod have changed the overall appearance.
The Piston/Cylinder Assembly is made on a CNC machine.
This new design does not change in any sense how it works and
so fits perfectly any Mamod engine that previously had the "old" shape fitted.
The piston still has the two "extra power" piston rings which are perfectly cut.
The cylinder has two Trunnion Screw threaded holes.
One hole when being used as a Standard type cylinder
and the other when fitted to a SP* type engine with a longer piston.
This assembly is not for SE* engines or the MM1 engine.
