Hi Fellas,

Okay, I know I'm picky. Way picky, but bear with me.

Tractor has upwards of 4,000 hours on it and judging from the drawbar, it has worked awfully hard in it's life. In addition, before I bought it for salvage, it had set parked in a shed for something like 5 or 6 years because of a blown engine. Never turned a blessed wheel in all that time.

Concern is the bulls. It has a darned bull-gear whine to it, which to my mind, is abnormally loud. It sounds just like an old Model A Ford only in a tractor version and I swear at times that I can feel a slight vibration in the platform corresponding to the pinion/bull mesh. Rust build up? :>(

I've spent a lot of money on this old tractor to make her new again. Everything works as it should and you really can't tell it from a brand spankin' new tractor except for that annoying whine.

I'm getting ready to pull it thru 115 acres of sod and will see how it sounds after that task is done, but was just wondering if anyone out there has ran into this somewhat irritating "bull-type noise" before and what did you do to correct it? Replace all the gears?

Wondering if some more hard work just might shut 'er up?

Thanks,

Allan

Morning Allen;Those old 1066's I used to run on the cane farm did'nt whine like that and we pulled them hard.I know it's not a red one, but my 3010 has a whine in all the high range gears, espesially when I pull it hard and after it gets that oil hot.This year I started feeling it with my feet on the platform in the form of a slight vibration.So,I guess I'll be in there this winter to see if I can't spend some money on it.Those Internationals are good tractors,I know because of the one I spent time on.Go with your gut as far as the plowing goes,but at some point you need to take a gander inside of the works.Have a good day. Kenny

Allan: Give this your utmost attention, Super As can break castings if things become loose in there. Just think what that 6 cylinder diesel could do. Try jacking rear wheels watching for looseness in bearings as you do this. You may even want to have a look at those gears.

Allan all the old IH's I have driven have all made a whining noise or a rawl noise and the fenders shook like crazy too so I belive you have a typical IH tractor.

Do you have this in all gears or just a couple ???? I know that you had a new t/A installed and if they overtightend the lower counter shaft you will think that you have a bull gear noise but the noise can telagraph from the speed trans back thru and up under your feet . if to lose then you will have a ratteling sound comming up thru. Guess you'll have to send me a plane ticket so i can listen to it or buy a radio and turn up the volume And don't worry about it it will all get aquainted . Some days i think you were related to my gramdmother on mom's side.

Picked up a very low houred (2700) 826 a few years back. It had obviously sat a while. In high range 3rd and some in 4th rolling up hill you'd think the fenders were loose & howling-especially at half throttle. Old IH mechanic friend said RUN IT. I notice it still howls a bit, but less than before and at full throttle hardly noticable or else I'm so old now I just don't notice.

Allen:

I used to run a 1066 with about 2000 hrs on it. Anytime you went to the field and pulled hard in low range, but especially in low third, there was a VERY loud transmission whine. This tractor is still being used every day by my Dad, and will be used by me next spring to disk 24 acres of CRP. Never been touched and it will still sound that whine whenever you pull her hard in low range. Tractor now has approaching 2900 hrs on her.

Like migraine noted,the wrong pto gear is really bad.Even the right one whines,and it changes depending on hydraulic or pto load.New gear against old,thats just the way it is.If someone has done any rearend work in the past you could have the same situation.

IHC used forged 1045 steel for all the gears in the drivetrain. A few of the pump gears were machined bar stock but not many. They were all carburized, except for a couple PTO gears that were induction hardened. Chances of Rusty gears is about Zero unless You drained pure water out of the rearend and no oil. Things that effect bull gear mesh are the condition of the rear axle bearings, The 66-series should have "Straddle Mounted Bull Gears" with tapered roller bearings supporting the bull gear. If they loosen or wear they could cause the bull gear to lose proper mesh with the pinions. The bearings that mount the differential & pinion shafts also effect bull gear mesh. If a bearing or gear has failed in the past it is very possible You have gear tooth damage. I've heard of the hardened surface of the tooth flaking off due to the heat of sustained hard pulls also. That can cause an increase in whine. Lots of those parts are "NLA" from C/NH/IH. And they were VERY expensive back when they were in production. It might be worthwhile to pull the LPTO unit and snoop inside the rearend, and maybe have oil analysis done on the HyTran in the rearend. Noise is one thing but if Your feeling vibration I'd investigate a bit, Your dealing with a MOUNTAIN of torque in that final drive. Those parts are Huge compared to Your 686.

Hey Doc,

After reading your assessment, I have the same feeling I do every time I go to a dentist or doctor.

First gut reaction is to tell 'em that, "It don't hurt anymore, bye". :>)

Does it whine under a good load? I would try her out and see if it gets louder. Maybe same as you needs to get the creaks out of the joints. You are feeling better, right!

Allan, most of the neighboring farmers run IH equipment, 966, 1066, even some 86 series. I listen to them when they come up the road, the tractors that obviously have high hours do have a noticeable whine, the lower houred tractors are not nearly as noticeable.

Allan, you took it wrong, I said HIGH hours, I don't consider 4,000 hours high. To apoligize I could send you a set of ear plugs,and then you wouldn't be able to hear that whine. Of course the ear plugs have been used a time or two but they still look good.

Allan, My ol girl doesn't have a whine at all. I would think it strange that your does. Did the guys who did the work on your open the rearend up to look inside at the time of refurb?
3 yrs ago when the clutch/TA, and lower rock shaft seals were done. Mine was opened up and inspected. It looked very nice, no chips or partial broken teeth. Sooooo .....
I wonder if a bearing failed in your tractors previous life and ate some bearing pieces and the teeth are scared up thus causeing the whine? Just a thought. Hope it isn't too bad.
Later,
John A.

Hi Guy!,

No, all they did to the rear end was put in a new PTO input gear on the front of it and go thru the brakes (which I still don't like, by the way..they squawk at times).

It is definetly not right because they shouldn't "whine" like that, or at least not this loud.

Your thoughts on the "chewed up gears" makes a lot of sense and sure would explain this noise. That is exactly what it sounds like. Beat up teeth.

I think I'm gonna put it in the field this fall and then park it back in the shop for a complete new set of bearings and all the gears this winter. They tell me that the way they are set up from the get-go will determine their life span.

Was just hoping that maybe it was rust build up from setting so long in the shed. Probably not tho. :>(

Yes Sir, I know they do. Like I say, I'm just a picky old man and want the old beater to be totally "new" again.

I think I'm just gonna pull 'er and see how she sounds this winter after the work is done. :>)

I own a 966 with about 4700 hours on it. It has virtually NO vibration, NO whine. Look at page 16 of the "Servicemans Guide for Farmall H. There is an excellent article on adjusting ring and pinion gears. LoAD BEARING WEAR PATTERNS, LASH AND CLEARANCE ALSO SHOWN. I'd say repair it BEFORE you break it. Did you have the ales out at some point? If someone did, then they most likely did not get them shimmed properly.

Mornin' Gordo,

No, this isn't a ring and pinion or a bearing noise. This is a flat out "bull" noise. The harder it pulls, the louder the noise gets.

I owned 2 of the rascals, which I bought new and remember how they sounded with that new-machine "singing" type sound. They all do that.

This is definetly the bulls talking to me.

turn up the radio or wear some ear muffs, pull the throttle open and enjoy plowing, don't get your coveralls in a bundle over a whine in a 30 year old brute. i had to take a few windows out of the cab on my 706 cause the whine was to much echoing in the cab. i thought the 766 was louder at first until i spent a few nights on a 1456 pulling a grain cart last fall. my neighbors are die hard ih fans and have just about every 06-56-66-86-88 tractor and they all whine. some more than others but they all whine. happy farming old man 8>)

I had a heck of a time for the first 10 days after we closed. There were days I couldn't even stand upright without pain.

But, I kept at it and now am kinda feelin' 18 again. Even starting to get some of my old strength back.

Don't know if I'm ready to start a rucuss in at the local taven just yet or not, but I'm sure gettin' better all the time. :>)

Allan, You sure the noise is not from your 60 year old body bull gears or maybe inner ear thumping? Yea funny how time and years of hard work finally start to catch up to ya. Just kiddin. I had a lot of noise on my 966 after we did the major on it this spring and found a lot of my rumble noise was coming from the fenders mounted directly onto to the axles. Put some rubber belting strips under the mounts and walla, much better. That plus I had a big old steel clevis lying on the platform that was making a fair amount of whine vibration. The worst was when we had that pto drive gear iside mismatched, that will make your teeth chatter after a few minutes. later Migraine

Hey You Old Hound Dog!,

I run into this all the time. My memory fighting with the real world.

I darned near bought a $4K engine for the 686 because I thought it "smoked" too much. Turns out it was me all along; I wasn't working it hard enough and the little tractor has turned out to be just a gem of an outfit.

I don't want to open the darned tractor up and there be nothing wrong in there. So, what I'm gonna do is just rack this up to a defective gear shift quadrant that you gave me. LOL!

It just can't be me. Right?
