Turbo kit for Perkins A4.248????

Did they offer a turbo kit to install on this model engine?
Was this engine built to handle a turbo and if so how many more horses can you expect out of it?

Thanks
 

You can turbo anything just don't put to much boost in it if its a naturally aspirated engine you will blow the head bolts in it
 
Hi There was an MF 590 tractor in the U.K that if tractor data is correct had that motor in we had a bigger non turbo 595 it had the factory junk 4 .318 in guys turbo'd them to. There was a Kit for the 590/595 and a few other MF'S made by a company called TB turbo. so yes it can be done. I you tube searched That 590 and there was a few different names came up to whether they were european kits or home brews I don't know . TB is the one I am used to hearing being originally from England. I'm guessing it would add about 20% to stock power if set up right so maybe about 90 hp ish at a guess. I wouldn't want to put a turbo on a motor with high hours though and work it hard every day without a full rebuild. Chances are something thats worn won't like it due to extra stress the turbo causes.Like worn rings, crank or rod bearings, or a head gasket that might be starting to fail under normal circumstances.
Hope that helps you a bit.

It depends on how much more power you want. Most tractors that have a turbo from the factory usually have about 10 to 20 more hp than one without. A 4.248 is pretty much a 4.236 with a bigger bore (3.975" bore vs the 4.236 3.875" bore), and they made a "lightly" turbocharged 4.236. The 4.236 has about 57 hp, the turbo 4.236 has about 78 hp. The 4.248 has about 65 hp. I have never heard of anyone turbocharging a 4.248, and never heard about the 4.248 having head gasket problems. If the 4.248 has the same bore spacing as the 4.236 the 4.248 head gasket would be thinner in some areas (less likely to hold the boost from a turbo).
 
Thanks for the info guys......I'm looking at both MF
3060 and 3070 tractors......
The 3060 uses the 4.428 non turbo
The 3070 uses the 4.236 turbo'd

I'd like the smaller size of 3060 for easy of moving
around in tight spots but need more power for my
application......need the horsepower of the 3070
really.
Could a guy install a turbo'd 4.236 in place of the
4.248 with no modification or headaches?
 
I think it should be a bolt in deal, on the 3070 the wheel base is a little over 3" longer, overall it's 4" longer (2wd), and the cab is 5" taller. The other difference is the tires, the 3070 uses 10.0x16 front tires, and 18.4x34 in the rear while the 3060 uses a 7.50x16 in the front, and a 18.4x30 tire in the rear. If the bolt pattern of the wheels between the two tractors are the same you could put the wheels, and tires from a 3060 on a 3070 that would make the 3070 a bit smaller.
 
236 is just 2/3 of the 354, both have the same bore/stroke. 248 and 372 have the same bore/stroke also. If I recall all four engines had the same block bore size for the sleeve OD, 3 15/16 bore sleeves were thinner. I've always thought ALL diesel engines should have a turbo for best efficiency, and will run cooler too. PROVIDING bubba don't get crazy with the full load fuel setting for a given job..
 
Yeah I agree, sometimes one can get carried away with the "smoke" screw and things can get ugly fast!
In my instance I don't feel the power of this 3060 will suffice......even after turning up the horsepower......running a 15ft batwing in thick green wet grass as tall as the top of hood on tractor is a tough long hard pull!
I even question if the 3070 has enough oats for the job???
If I knew for certain that a turbocharged 4.236 out of a 3070 would fit in a 3060 it would help my decision making much more.......this 3060 I found is a mint tractor and fairly cheap so I'm kinda hung up on it!
 
A turbo makes an engine "seem" bigger by providing more air. Every 14.7 PSI of boost adds 1.4 times the amount of air, add the respective fuel and that equates to horsepower.
 
The 4.236, and 4.248 use the same intake manifold, rocker arm shaft, valve cover, and many other cylinder head parts. So it would seem all the turbo parts from a 4.236 should bolt right on a 4.248. The 3060, and 3070 both use the same transmission case, and front axle support
 
I wonder if the valve train and pistons are the same
in both engines?
It would almost be to good to be true and easy to
just pull a turbo off a 236 and slap onto a 248!
I'll have to get on agcopartsbooks and do some
comparing.
Thanks
 
The 1100-1130 differences were several. Turbo engine had hardened exhaust seats, rods drilled for oil to pin bushings, hardened crankshaft, four ring lower compression pistons instead of five, 10MM injection pump plungers instead of 7.5 MM, higher injector opening pressure were some engine changes. The 1130-1150 both had a heavier rear driveline than the 1100 did. Engine wise all the 1130 turbo parts will bolt in the 236 block.
 
On the newer 3000 series tractors the engines use more of the same parts as possible compared to the older engines used on the older 1000 series tractors. The 3060 with the 4.248, and the 3070 with the turbo 4.236 both have the valve seat inserts on the exhaust (both engines use the same head). The pistons will be different because of the .100" difference in bore diameter (the newer 3070 with the turbo 4.236 uses a 3 ring piston). The crankshaft is the same on the newer Perkins. The connection rod is different for the heavier piston the 4.248 uses. The injector pump, and injectors has different part numbers between the two engines because of the engine size. The thing I see that maybe a concern on putting a turbo on a 4.248 would be the head gasket. With the cylinders being .100" bigger in diameter than the 4.236 you have that much less head gasket between the cylinders.

On another note Massey Ferguson did make a agricultural model F290 tractor with a turbocharged 4.248 for high altitude use.
 
Hi ptfarmer
As far as I know that TB turbo kit that was fitted in the U.k went on a stock tractor engine right from the factory. Dealers fitted it in their shop
or farmers did it them selves, somewhere here I might have an old advertisement in a magazine from the day. Those conversions were done way before my
seat time began. many of them are still running now. Was kinda hoping David in wales would of chipped in. He may know a lot about these English 590
tractors and the turbo kits fitted, and if anything was changed internally, as he seems to be well informed on tractors around that age. Maybe MFrules shuold try asking him what he knows to if he's still thinking about this project.

Hey guys, I appreciate everyone's response to my
questions.......I admire/respect all your guys
knowledge on here!
I don't question anybody's posts on this matter but
I'm not really interested in just experimenting with
throwing a turbo setup on a 4.428 and hoping for
the best.......if corn was $7.00 and beans $15.00 I
wouldn't mind experimenting but margins are tight
now in the ag industry......
Sure wish someone would chime in and prove to
me that you could for sure just throw a turbo setup
off a 4.236 onto a 4.248 and all is great.......or
transplant a 4.236T into this 3060 that has a 4.428
in it. Reliability is another issue......when it's farming
time I wanna get the job done......time is money, I
get really agitated when the neighbor is working and
I'm in the shop working on my stuff!
I'm probably gonna pass on this project until I can
get some solid info as to what can be done......to
much in question and as most things go you have
twice invested in a project then
expected......sometimes it just isn't worth it!
Thanks to everyone!
 
I would swap the complete 4.236 turbo engine in since its a proven engine. You never know the non turbo 4.248 may surprise you. I have a MF 2135 industrial with the Z134 Continental gas engine. I was very skeptical about the 134 gasser, but it really surprised me on what it could do, and how fuel efficient it is for a gasser.
 
Hello Robert, David in Wales is at this moment about to leave LeHavre in France en route to Portsmouth in the Uk. A short bit of advice for now do not entertain the fitting of a turbo to a worn engine. The fitting of a turbo creates a lot of problems in terms of extra stress on engine components, cooling and oil supply. I would not fit anything unless the engine was in VERY good condition to start and then only one approved by MF. Will reply more when home. DavidP
 

Perkins 236 turbo has heavier connecting rods and bigger piston pins and pistons have steel top ring grooves. Controlled expansions pistons. Also piston cooling jets. These are the reasons why a 248 does not hold up that well if your trying to make over 100hp with it. 248 pistons can't take the heat and might seize if run long and hard. I have had a 3060 tractor with a turbo, it was around 90 hp and performed well. They are actually very common around here, 590, 690, 390 and 3060 all had the 248 and it was very common practice to fit a turbo kit to them. Most of them did fine, but it does shorten the engine life no doubt about it. Most turbo kits came with an oil cooler, that is also standard on 236T.

All 236s and 248s are interchangeable if they have ag style block. Also 1004.4 and 1104.4 engines will interchange with those older models. Water pump and thermostat housing might be different depending on application. If you find a 1004.4 Fastram engine they all have turbo pistons in them and they also have 8 port heads.
