220 Engine

Back in October I thought I got a good deal on a seized '72 220 with air conditioned QCS cab and duals sight unseen. It shows up and I couldn't see any coolant in the rad and the oil is overfull too so not a great sign and so it sits in the yard for a while. Fastforward to last week I get it in the shop and start pulling the head off. Two cylinders still had water in them one had rust dust in it and the other three were rusty as well. Next I find the front pulley moves after I got the fan belts off. So I pull the front end and oil pan off and find the crank broken in front of connecting rod #1. So the question is should I get a new crank and overhaul the 3500 or swap something like a cummins in. I think I'd like to get it to make 200hp or close to it. Any ideas appreciated. Thanks

Lots of 3500 parts out there. Like said above, get it apart and see exactly what you need. Combine engines, or Military gen sets are great sources for engine parts. 

here's one for sale, would be a little bit of a drive but, take what you need and scrap/resell the rest???

The engine is original to the tractor I presume because the paint matches all over the tractor. I checked and the crankshaft had been reground in 1980, so whatever happened I don't know because the tractor would have still been fairly new then. So far the engine looks rebuildable luckily the water didn't freeze in it.

The oil pump is mounted right below the crankshaft so i'm guessing it's the later crankshaft driven one. I can get the engine serial no and tractor serial no this weekend. I think the tractor's # put it somewhere in 1972 according to tractordata.

If it is that late of a 220, it would have had the crank driven oil pump from the Factory. It also should have the "fast" low range in the range transmission. This makes 4th gear 5.8 MPH instead of 4.5 MPH. This was the same gearing that the 220 FWA tractors had.

So, the 3400/3500's are a different crankshaft than a 3700. And the 3750 is also different than the 3700.  A gen set is always a 3400 or 3500 and should be equal strength and quality as a 3500 in a D21-210-220 engine ??

Seldom is a modern diesel crankshaft suitable for regrinding when there has been a bearing burn-out. It might even magnaflux crack-free. The problem is the metallurgy has changed from something that was very hard and durable to something that is now softer and weaker. Imagine taking a Grade 8 bolt and heating it just up to the point of turning it red. Do you think it is still a grade 8 quality after that ?? NOPE. I personally know of a local machine shop that has reground cranks like that and within 100 hrs they are broken, right where the bearing failure had been before. The other issue is many machine shops are automotive specialists and don't understand how to properly do heavy duty diesel engine cranks. The fillet radius must be done correctly or the crank will one day break at that point. Cars don't have a fillet radius like heavy duty diesel cranks.

It says JAPAN right on the head of the engine so it wouldn't surprise me if there was more parts on the engine made there.

AC_220 where are you in Canada? I'm in western Ontario. I have a complete engine that was in a salvage yard 210 that I bought. Engine was tight. Had a rebuilt 220 engine for the 210. Should have the correct crank for you. 

I was in Maxville a few weeks ago. Likely almost at your place !

Did AC not have the plant capacity to cast their major engine components in house, or was it cheaper and easier to outsource? This time period was in the Glory Days of engine/tractor production with the major downturn in agriculture looming just over the horizon., Mike

Maxville is 40min give or take some from where i'm at. What was happening there? Thanks for the offer WF owner, i'll keep that in mind.

AC_220 We built two silos for MacEwen's feedmill. Also built the big silos for P&H in Winchester 20 years ago. Built a lot of farm silos in that area in the early 70's
