C113 Oil seals

I have a 1949 Super A with a C113 engine. The engine was stuck but now freed. During the process I had a cylinder sleeve to come up. So my question is, are all outside dia. of these sleeves the same? I would not think that they would change the outside to make a bigger bore. I need to find the sleeve seals for the cylinders. I am pretty sure that the inside cylinder measures to be original. All measure right at 3 inches. And are there any secrets to install these rubber cylinder oil rings?

Thanks,
James
 
you need to use the proper lube on the o rings. liquid dish soap, murphys soap as in the tire mounting lube stuff. I have even used brake fluid. make sure no pits in o ring contact area. you will also need to check your sleeve protrusion height, about .004-.006. they will just press in with steady hand pressure.
do not use any oil on the o rings as this will swell them up. cooking oil would probably be a acceptable.
 
Yes they are all the same and if you had one come up it means the o-ring is old and probably hard get a new one and mite a well replace all of them as now would be a good time. Liquid soap makes a good lube to install the new o-rings.
