Deere 55 - Roundback motor in a squareback

Anyone ever replaced a HE217 with the older HC217 motor? I"m hoping the bell housing will swap out. Anything I should watch out for?

Thanks,
Brad Bachelor
 
My early 95squareback with a 217 will keep right up with my neighbor/buddy's 95 with the 303.According to the book,the difference between 217 and 303 is just THREE horsepower.
 
According to the book that is right in front of me,the 55 uses the HE217.The 95 uses the HG217.As far as I can tell(from personal observation),the 55 uses an updraft carb,the 95 uses a (2barrel) downdraft and is wound a little tighter.
 
The only difference I can see is the flat belt pulley on the bell housing. Bore,stroke, and horsepower is the same. Valve clearance adjustments are a little different.
I'm going to have to swap the bell housings and I'm not sure how big a job that is.
Any secrets on the bellhousing?
 
Sorry,I cant help on that one.Except you you may need to use a large screwdriver to help seperate the halves of the housing.they get hung up on the dowel pins once in a wwile.
 
Thanks for your help. I'll be a bell housing expert shortly. I just wish I would'nt have to become an expert with money still in the field
 
The rpm of a 303 in a 55 was 1900. The 95 rpm with a 303 was 2500. Horsepower was 72 in a 55 and 90 in the 95 with the 303 engines.
