IH 966T or 1086

Looking for input on two different rigs I am looking at. One is a IH 966 turbo with open cockpit and the other is a 1086 without a turbo but has a rather nice cab setup already on it. I wonder if the cab is worth going without the turbo or am I better off stepping down a size but gaining the turbo. Are there any concerns looking at the turbo model? I know you have mentioned overworking a turbo and other items so what do I look for? This would be my first turbo. I will snap a couple of pictures and get the hours and details as soon as the sun comes back. I won't hold my breath though because that could be awhile. So, any thoughts on either of these two beasts?

The 966 was built with a 414 cubic inch naturally aspirated engine. Many 9's were fitted with aftermarket chargers. The 1086 was built with a 414 cu in turbocharged engine. Never heard of anyone taking a charger off a 10. Either tractor could have had a different crank and pistons installed in the original block to build them up to either 436 or 466 cubic inches by now. The 9 was built with a smaller clutch and different flywheel than the 10. Used to be that the 10's flywheel was available in the aftermarket but the 9's was not so some were converted when the button clutch discs finished off the flywheels.

We have a 1086 that Dad bought new, darn good tractor and the shifting isn't a problem when using it for a field tractor, as it was intended. I wouldn't enjoy it for loader work, but that's just not what they were designed for anyway.

Never heard of a 1086 from the factory without a turbo on it. 966 with turbo would be added on after it left the factory...

The FIL and wifes grandpa both have 1086`s without turbos. I`m pretty positive they are both factory that way.
Like others said, kinda depends on what you are using it for. Both are good rigs, I just like the looks of the 66 series tractor alot better.
The 1086 will be a rougher ride, I also don`t care for the shifter setup on em.

Hmmm,

Never heard of that one. Which engines do they have? 414 or 436?

To tell the truth, I don`t know enough about those red ones to tell ya. The grandpa`s got sold this fall, so I can`t chech that one out. The FILs I can investigate closer when I`m back over there. I`ll let you know. I don`t know for positive if it never had a turbo, but know it never has since he`s owned it (about 10 years).

Well,

Could have been, I guess. Back when they were changing over to the '86 series, all kinds of strange things happened.

The very last of the 66 series got the 86 rear ends so guess maybe a 966 engine slipping into a 1086 is sure possible.

It would sure be interesting to know tho. If your FIL's tractor has a 436 engine, that would make it a 986 with the wrong stamps. If on the other hand, it is has a 414 without a blower, that indeed is very unusual. :>)

Are you sure it isn't a 186? That would be a 986 sized hydro tractor and therefore wouldn't have the huffer.

As hard as that SOB is to shift, I`m pretty sure it ain`t a hydro. Where would a guy look on the motor to ID it. Is there somewhere I can pull a serial number off the tractor to find the year.
Let me know, I`ll be going over there this weekend to help out with chores and do X-mas stuff.
I`m sure if your on top of your game today, there will be pictures from every angle to show me where to look :)

What a stroke of luck; just happened to have some red tractors setting outside in the snow. :>)

Stamped on a pad on the left side of engine, dead center, up at the top of the block under the intake manifold. First three digits are cubic inch.

Will there be an NA or something in the number for normally aspirated or not? Also where do you find the tractor serial # on these beasties?
This is cool, I`m getting a red education today.

Don't know all the secrets of the serial number. My turbo engine serial number says 414TT and the one without the turbo says 414DT. I haven't got a clue if that means anything or not.

However, tractor serial number should be down on 'er belly on the right hand side of the tractor.

Hey thanks bud,
Now I got a mission to go on this weekend.
I`ll report back my findings as soon as I find out what my findings are. Which should be a whole lot easier now that I know where to find what I need to find. Later

While your there look under the hood and see if you see a turbo up there.

That's the easiest way to tell if it has one.

The serial # on the 86 series is inside the cab near the floor on the fender.

For most all intents and purposes, they are basically the same exact tractor. The 1086 will have a nice cab and the extra power from the turbo.

All depends on what you want to do with the tractor; don't cut that 966 short, they are one heck of a bull. Just doesn't quite have the "umph" nor the nice cuishy cab like the 1086 has, but they ride a lot smoother than the '86 series too.

Both are heavy work tractors and aren't worth a darn for just "putzin" around. Both are very expensive to repair.

Unless someone has taken the turbo off the 1086, it should have one on it. My dad used to have a 1086. Was a good tractor, it had a turbo on it.

Why is there no turbo on the 1086?

The rear end on a 1086 is heavier for one thing and the cab is pretty nice if it has working air.

Kinda depends also what you are going to use it for.

Are you sure you're not backwards? I have never seen a 1086 without a turbo. If the 966 has one, it has been added, I don't think it was factory installed.
