7050 turbo exhaust and intake manifold

So I am buying a 4910 Hesston 4x4 big square and planning on tying it behind the Allis. It's been raining the past few days so I have done a lot of wire removal and cleaning up. None of the gauges work and I am tearing out the factory panel out in favor of custom gauges. (tiny tach, ect, egt, hyd psi, oil psi, oil temp, hyd temp, boost and whatever else you suggest.

In the process I found my turbo has a hole in the exhaust side, Crack in the manifold, and a blown intake gasket.

What should I do to get this fixed? 7080 kit maybe? I see people saying to update the turbo but w/ what model?

Have you checked the AGCO parts books website? IDK if the turbos are different or not.


If Sturgeons corner doesnt have what you need, Mike's should have it all.

Mike also has a decent 7040 that he would sell running. because, after all, Tractors dont require tags, so they are cheaper to own in multiples. :)

personally, I would keep the factory turbo, as with the full load/ no load the plunger gives, I would want quick boosting, but I have never pulled a ton baler (pulled small square....glad we dont do that anymore. :) ) so I may be thinking about it all wrong.

Over time I've found it's usually much easier, more economical and usually more functional to just stay as close to factory or factory replacement as much as possible. Just my small input as I used to get grand ideas like changing a D19 into something closer to 190 platform. Never did it but if I had I would have a devalued tractor that probably would have cost way more than just replacing the D19 with a 190.

I figured I need most of the required parts anyways so why not upgrade? My hood is junk so why not replace it too? There is also nothing I can do to devalue this tractor, it was saved from a scrapper.

I was thinking maybe a holset turbo, those are quick spooling but not sure of the size needed. I was going to use my 8930 size to base my guess off of.

I am sure my current set up will pull a big baler just fine but if I can pull a big hill and bale w/ power to spare and get better fuel usage.

Thanks doc, now until I piece together a 7080 inner cooler kit or make my own I might run the hx w/ just the stock intake. What problems would I have here?

If the exhaust manifold is the same then I will try to get it welded up or something.

That's odd, I don't think my tractor has an intercooler. Is it the typical ata cooler mounted in front of the radiator?

My turbo goes directly into the intake manifold.

I'll take a better look I guess (could have over looked something) and some pics.

I can't weld cast but my local machine shop can. If not I'll order a new one, it was worth the $20 to try.

Ok, I am just used to my newer tractors that are all air to air, that explains why the intake seeps coolant out a couple bolts and is so stinking big.

Most guys with 4x4 hestons around here run them with 225+ HP. Level ground you may get away with it. Any hills and heavy material you may be in low gear. 4x4 balers take allot of power just from pulling the shear weight of the baler.

Be sure to glue the intercooler to cyl head gasket on both sides with a cement glue of some kind. Also recheck mtg bolts after a couple of days running before start-up in the morning when cold.

I glue gasket to manifold with yellow 3-M 8001 and let dry/get tacky. Then RTV gasket to the cyl head. Nothing on clean bolts as a rule.
