perkins 4 cyl diesel

Woodbeef has made some very good points about this proposed conversion. Also, from what I have seen of those tractors, they are quite traction limited with the 3 banger, never mind giving it more power to spin with the four. I've always thought that most of these conversions were done for the sake of it, not the practicality. It may cost a lot more to convert than buy a new block. The extra length of the four cylinder will also increase the wheelbase of the tractor, change the weight distribution (probably worsen if that's possible), and make it somewhat less manuverable. One option that I might explore is to repair the block. There are speciality outfits that do this work, and if you talk to your dealer or local engine shop, they might point you in that direction. Again, cost is a factor, and a new block might be cheaper... I have heard of structural Ford blocks that were repaired after a rod went peek-a-boo. But it's your choice. Just about anything in this areana can be done if you have the money, know-how, and time, probably in that order. Good luck.

Rod

Go out to your tractor,and look at it from a side view. Now imagine that the engine is now oh....lets say 7" longer(this is a structural tractor so the lenght of motor makes a difference)Ok once you have envisioned the extra lenght,now look at every thing that must be modified to fit this 4 banger into your tractor..... Now look under the hood and figure once again. Ok lets just say you did shoehorn the 4 banger in and got it bolted down(what does freakinstine now look like,eh?)..... .now will the tranny and rear end survive?

Good luck!!!!!
