Hello Everyone, I am running into a problem with my JD 310c. We bought it used and apparently it had a preexisting issue with the Head. The mechanic found the head had a large crack in it and cannot be repaired. Someone had worked on the head quite a few times already and the head gasket was installed backwards as well. We are looking for the Vin to get a replacement head and the plate isn't there. Is there any other way to find the correct head for this model? The 310C apparently has 7 heads from that model and that's all we know. I know it's not a turbo for sure, but I cannot find how to match the model to a head for sure without a vin. Any advice is appreciated
Welcome to HEF HelpImLost . Assuming the engine is original , the engine serial number or the cyl head casting # is most important.

The bare head is not available at Deere. . Engine model 4039 above serial # 300000 (cyl head marked R111949 or R97628) ,ALL sub to complete head part # RE48615 or Deere Reman # SE501585.
