986 turbo

I know it has been done but I have some questions. One what size turbo and 2 how well does the trans hold up to that much power if you were gonna farm with it?
Thanks
John

They work just great.

I had one years ago, farmed like a banchee with it and am in the process as we speak of putting one on my 966.

Just flat makes a "10" out of 'em.

Problem is most farmers made 14s out of their 10s.

Ain't it the truth! Probably what I need. :>)

Thats kinda what I thought but wanted another opinion. Already have a 886 with a m and w turbo kit and 1086 so a 986 will fit right in. We dont push to hard the 886 is around 120 the 1086 150 or so and both are spectacular machines.......except for possibly the worst shifting linkage design ever lol. Thanks again guys

and the problem is what . Don't come checking the 1066 we had then cause it is layen down more then a 15.

why are you worried about the transmission here it is the same as a 10 or 14 and the same as the 886.

Bigger clutch, a couple of bearings in the transmission, larger bull gears and bull pinions, a couple of brake disks, larger axles, and larger final drive bearings and you just turned your 986 drive train into a 1086/1486.

When you put a few hours of real work on it you'll know.

I wouldnt say im worried just curious what others think.

Guess 4500 hrs is not enough yet to tell since i went thru that tractor from the radiator to the PTO back 89 and it has been the main H/P for all the heavy work since . Does all the moldboard plowing discing and now the deep ripping an chopping . The only repairs made to it has been a couple lite switches new park loc linkage a couple new seats and a new set of tires . Still on the same clutch and T/A that i put in it back then oh and we had to redo the injection pump this year because of a governor issue in the pump . oh and set of brakes. So when the day comes that the pin falls out and she pukes her guts out it will not ow us a thing. That tractor was bought buy a close jocky friend of mine at a sale one day that i could not make as i was going to a larger sale and i told him to try and get the 1066 and the 966 that was at that sale . He got me the 1066 but not the 966 am i bought two semi loads out of the other sale . He hauled the 1066 to Tri Green's sale where i picked it up and paid him . Lets just say that it was not one of my better buy's . When i got it home i started checking it over and it needed everything. a guy came in and wanted to buy it and i was straight forward about it and told him that it was almost junk. The T/A was out the ft.end was wore out third gear was noisy it needed painted but it did run ok.and it was gone. A year later Eugene comes dragging this THINK home and says you can fix this. Well we did FIX it and i do believe that i had Every nut and bolt out of that tractor from ft. to back top to bottom . If any part was questionable it was replaced . We have all older equipment and like most of the local farmers we keep the old going.

The biggest worry would be the clutch as it is a 12 incher not the 14 inch and they seam to be the weak point on 966-986 when ya get to carried away . The head and pistons on them are also different between a turboed engine and a non turbo. The 986 runs a D436 non turbo .

What are the differences in head and pistons? Is the cam different to? Im pretty partial to the 66/86 series to and always eager to learn more

When you hit 8000-9000 hours let us know.

Now, I have a question here. Would putting a turbo on take all of the lugging power out of that tractor? I ask as people tell me I need a turbo on my 806. I haven't done it yet. My neighborhood has more deere, and the 4430 I grew up on will fall flat on it's face below about 1,600 to 1,700 RPM. I spent a few hours on a 4230, and other than being gutless compared to a 44, it seemed to lug better, like my 806 will. That 806 seems to be able to lug all day if asked to. I'm just curious as what to expect if I ever did turbocharge it. Hopefully I'm not starting an arguement.

what kills lugging power with a hair dryer is that point that you either get under the boost pressure or it starts to hold the pistons back from over pressure . I also have a UGLY 806 diesel that runs like a scalded dog and it is set at 110hp with out a turbo . Many years ago when the 806 first came out the person i worked for bought the vary first one in this area and the tractor was not three days old when he had a Turboneic turbo installed by a local company here . The next weekend i went with my uncle when he bought the second 806 and like my boss he had the same company install the same set up. Spent many hours on both of them tractors and back then man they were the horse. A close friend of mine has a 64 806 that has had a turbo on it since day one and it is set at 128h/p . Now as to the H/P of my old bosses and my uncle's i can not tell ya but i can tell ya that we could pull the John Bean two row tater harvester with out any extra tractor hooked on the ft it would also handle the 470 18 foot disc in first high in our hills .

as to what is different on the heads i can not say for sure as i do know that there are several different heads for the 400 series engines and as to the pistons it is the compression distance . And as i have never been into a 966 or 986 engine i am not sure if it has and extra piston cooling jet in them or not . as to the cam there are two different cams used one for early side breather engines and one for the B series or top breathers.

Buy that time i am sure that i will not be around to tell ya about it .
