tractor motor swap
 

idk if there are other forums for this sort of question but here goes, i have a pc-20 komatsu track-hoe with a little 3 cylinder yanmar diesel in it, the motor developed a terrible knock so i pulled it the other day and im wondering if there is way to put a different motor in it to lower the cost of fixing it, those yanmars come form japan and hard/pricy to get parts for
