Bottom end of cylinder without sleeves:
There is one large, but thin O-Ring in a groove in the bottom end of the cylinder at every sleeve.
Does anyone know what that is for ?
Can it be left away or is there any other solution to seal the lower end of the sleeve to the bottom end of the cylinder ?
If this O-Ring is absolutely necessary, that and the needed groove may become the restricting part of all that stuff 🙁
Currently I am looking for a sleeve with a ring at the upper end.
Ring should have only 1 mm of extention to the outside and another 2 mm of sleeve wall thickness will lead to 87mm bore.
Displacement will be:
r² x pi x h x 2 = 927 cm³
It may be easier from the mechanical point of view and to avoid minimal thickness of cylinder block components to go for a 86mm bore, which will provide 906 cm³, which is still starting with “ninehundred” !
Cheers, Michael
