International 444, 1968. Progress Thread, Getting Going

[DJ54]

Here are a couple pictures showing the ring gear and starter. They aren't the greatest, but the ring gear doesn't appear to have any "missing teeth" in the area that is exposed. Just the gear on the starter seems like the tips of the teeth are worn down.

I've seen gears a whole lot worse, but being you had to lube the bendix to get it to work somewhat better, wondering if it wasn't fully retracting causing wear on the flywheel teeth. Most have a pretty sharp edge. Some straight, some on a bevel.

Welds on the exhaust pipe aren't pretty, almost looks brazed rather than a weld, but either way rusty pipe is not easy to get a good looking weld on. As my buddy used to say, "Pile it up high enough, there's no way it's going anywhere."

You can find numerous threads on the carb. solenoid from different tractor forums doing a search on Google for fuel solenoid on a C-153, or IH 444. Not to steer you away from here, but the Red Power forum is a great place to find answers, just look for them from there when doing a search for above items, either C-153, or 444.

Thanks for the info. This is quite a learning experience on a lot of levels. All the resources and tidbits here help. I was not aware of the red power forum.

Ive done a lot of mechanical and electrical/electronic work over the years. I wont recap everything here, but electronic down to smt board level repairs and I am getting ready to rebuild a powerstroke 6.7 in the near future (ive done a lot of work on it in past years already, but this time it has to come out and everything taken apart). The tractor at the moment is the priority - we need it (even limping) to do some critical property maintenance.

I am going to try my theory of blocking off the solenoid port with a bolt. I realize that probably will cause some run-on, and possibly running backwards for a moment, on shut-down, but Ill try it and see what I get. I dont want to take the head off and clean the soot out of the combustion chambers if I dont have to. Down the road when I have more time and can leave the machine down maybe. Right now we need to get it usable.

Doing the math on the solenoid threads -
10 threads in 1/4" - the caliper points are 1/4" apart:

That means the pitch is 40tpi. That is more fine than "fine thread" 1/4" at 32tpi. That might be next to impossible to find a bolt for.

Next idea - using a ball bearing to close off the ports when the solenoid shaft is in.

That or trying to get the solenoid operational.

Found a diagram of a similar Marvel-Shebler carb.

They call out the "power adjusting needle" in the location where the solenoid + needle adjusting screw on the top sit.

Now I realize the whole needle rod is missing on mine = blows my whole theory out of the water.

Maybe it will run the way it is. We'll see. Might get too much fuel.

There "should" be a brass tag somewhere on the carb with a model number. Should be riveted on the side, or on the bottom. Case/IH shows 3 different ones were used. But use that model number on the carb to find parts. Maybe type into Google the model number diagram, or the model number power adjusting needle. May come up with a diagram showing part numbers. Just be sure it is that model number you have. You'll probably get a ton of hits with M-S in the search. Might refine it by putting it in quotation marks. That way you'll get the exact part you need, even if going with the solenoid. Neither seem to be cheap.

I'm not where the machine is sitting so I can't easily check. I went through my pictures and the only ones I have show the assembled carb from the direction it is mounted on the tractor or the insides. The only indicators I see on it are the "Marvel-Schebler" in the cast flange that bolts to the intake manifold. It may be thursday at the soonest I can get back to it, or if not this weekend. We'll see what I find.

Don't know your terrain. We've got a (diesel) 444 here. Though it's now parked in the woods (wife's cousin next door owns it), I'm the primary person who's used it for the last 25 years prior to being banished.

I've always felt whomever designed the brakes on that should be disinterred, biach slapped, then maybe fed to the fish. The brakes on this thing are useless. Not being the owner, I finally went to fix some things on it, brakes being one. I got them improved but never really working like I'd want. Fortunately, we've got hills and to slow down or stop, you can (if needed) steer into the slope to do so.

Long winded way to say, if the brakes on yours are the same ball & ramp style, AND your terrain allows, I'd put the brakes down the list of issues to worry about. Perhaps you've done that. If I were to drag this out of the woods to get it functional again, the brakes would get some attention but they'd probably be the last thing I'd worry about. The machine pretty much stops on a dime when you clutch, unless of course, you're pointed up/down a hill.... I was always able to adjust for that reality.

Case/IH shows 3 different ones were used.

For what it is worth, also, the IH-201 shop manual (which covers many machine models, of which the 444 is included in the series) shows 5 different carbs:

Zenith 67x7
Zenith 267x9 assembly # 12685
Zenith 267x9 assembly # 12758
Marvel-Schebler TSX748
Marvel-Schebler TSX857

Based on that I am assuming, at least it is very likely, that what I have is one of the latter 2. However, that may not describe "every" C-153 engine config. I do know from past experience that IH and CNH may show consecutive SN's of equipment, but if you get down to the production level history you find that short SN ranges (sometimes 2-5 units) were held back and parts were swapped in production. We found this with wiring harnesses and valves in some 90's to earlier 2000 machines. The earlier machines had the "new" harnesses/parts.

What I can also say is those SN swaps were generally within about 10-20 from either end of a production run/series. My SN is about 250 above the 1968 model year break, but that does not describe any "production run" break where they may have supposedly implemented any changes.

I have to agree those style brakes can give you fits, but unless the bull pinion shaft seal is leaking, they can be cleaned up well and work like new again. I have 4 IH tractors here with that style brakes on them and also had and old Case 310B backhoe with the same style brakes but got them all working very well.

It seems that at times, pressing on the brake pedal is like stepping on a plum, and you get very little braking action. The brake discs get what appears to be a waxy surface when you get them out. If they are not oil soaked, you can buff the surface with 100/120 sandpaper and rough them up a little. I now use my air angled die grinder with the 2" roloc disc head, and generic medium fiber type roloc gasket removal discs. 10X faster than using sandpaper and leaves a slightly rough surface.

The other problem is when you press on a brake pedal a wheel will lock up and most times stay locked. Putting it in reverse will unlock it. This is due to the large ball bearings getting rusty, along with the ramps. These too can be cleaned up with sandpaper, or as I now use my die grinder with disc. They do sell new ball bearings which I believe are 7/8" in dia. I did replace the ones on the Case hoe because they were really pitted. Everything else just buffed off. The 2" disc will clean up 90% of the ramps, just the very bottom needs finished with fine sandpaper (I use wet & dry 120 grit as it seems to hold up better and more flexible).

I then coat both with a light film of never-seize, using my fingers. Just put a small blob on with the brush, then use my fingers to smear it around. Too much and it could get on the braking surfaces. Reassemble and adjust, you're good to go.

You do have to be careful when removing the little coil springs as the hook will break off and you'll need new ones. But some are rusted so bad in the hook they will break no matter how careful, or just plain worn. With having that many tractors with them on, I have a few spares in the parts cabinet for just in case.

I've found over the years this happens more on my Super C's than any of the others, and normally after 3-4 years and going through the Spring sweats here. When it's been cold, then get a day when it warms up into the 50's-60's and condensation forms on the cold metal setting in an outside unheated building. Normally they will get a little sticky before getting to the full locking stage. When I notice it, I know it's time to take it to the shop and do some cleanup.

I bought my air angle die grinder at Harbor Freight back in the late 80's when they were mail order only, and grinder was made in Japan, not China. I must say, it still works very well and use it quite often. Got the Roloc head at NAPA, but there are many brands now for a lot less. The discs I get at a local Swapper's Day over the Labor Day weekend off a tool guy there. I get 50 in a box for $20, but get a break is I buy 2. They seem to last just as long as the 3M brand which are a lot more expensive. This tool guy also sells them on ebay, but for a little more to cover cost of shipping. I go through a lot here, as it seems I'm always working on something. Great for buffing/cleaning gasket mating surfaces. Sure beats doing it by hand.

Just some food for thought on the grinder/Roloc style head. One of those tools once you use one, you'll wonder how you got along without one. Did a quick check and for around $50-$60 you can get one of the better, not professional grinders, a generic Roloc head, and a box of 50 aftermarket discs. That is if you have a decent compressor to run it.

I thought it was strange no pages of the C-153 engine only, showed the solenoid. That's where your hard copy parts book should come in. I don't know if they used the manual adjusting needle on any models before using a solenoid on carbs with the same model number. But using that model number will be the key to finding what you need.

I'm thinking there may be a part number on the other side of the top mounting flange where you can see M-S cast in. Using that number may help you find a parts diagram for it, if only used one that one particular carb model. Could be one cast into the bowl also.

I just picked one out of the three listed in the parts catalog and did a search using the model number. That particular carb. was used on a lot of different brands and models. Too much for me to go through just being a spectator.
