Shaft length issue

I ordered what looked to be the exact replacement engine for my old mower.  While the engines look identical, the new engine has a much shorter shaft.  Is there a part I can get to make the shaft longer, or some type of conversion kit to make the new engine work with my existing mower?
 
Thanks,
 
Bill

    It sorta like lumber is a lot easier to shorten a shaft than lengthen it.
     
    What make, model, and type (spec) number did you have and what is the new one. by going just looks you could even have a different diameter crankshaft PTO end.

    The only way to fix that is replace the crankshaft which gets expensive. Did you order the specific engine or did the supplier cross reference it for you. If their mistake they should take it back as long as they are a dealer.

    Thanks for feedback.  I bought the new engine straight from Briggs Stratton.  The two are identical, so assumed it was a direct replacement but the new engine has a drastically shorter crankshaft.
     
    This is what I bought:  Briggs and Stratton 126M02-1018-F1 190cc
     
    Again, identical to original but seems the 163cc engines are used now for my type of mower - Toro 22" Recycler

    What are the numbers from the old engine? They are likely very similar but controls and shaft length/diameter vary depending what the OEM wanted. If you ordered that engine because 'it looked the same' and didn't look up the direct replacement on the Briggs site  you are stuck with it. If you change the crankshaft yourself you void any warranty.
