G80 - 18M crankcase swap

Post by ajsmike »

Dear friends. Iā€™m building my 1953 18m rigid from scratch.
I have a good G80 engine complete and want to swap over the crankcases with some year correct AJS 18m cases.
The G80 engine is same year, 53ā€™, as the 18M cases.
Question : are the internals exactly the same ? Are there bearing differences or anything that can prohibit me?
Thanks in advance. Newbie AJS owner.
