I have an 18 HP horizontal (422437-1209-01) that has a broken rod. I just got a 42A707-1237-01 vertical shaft 18.5 HP. I want to use parts to fix the horizontal for the Craftsman II Steve has repainted. the crank #'s are not the same in these:
Horizontal #: 690639
Does anyone know what the difference is between these two cranks? Neither engine is apart right now. Just looking for info. The rods and heads are the same part #, hoping the cranks interchange.
