Dresser 250c track specs ?

Hello all: Long time lurker and new poster. Ive been wanting a T loader for a while and think im finaly gonna enter the misery. I have my eye on a 250c dresser and wonder if any IH fans may have the track spec info on this machine. I know over at RP there was a post on it but has been since taken down. pin size, rail height etc.

Ill just rattle on a bit. I was intending to go with a 175C I found local. It had sat out for 8 years and was about a 1978. The story of why it got parked varied differently depending on who you talked to at the outfit that owned it. They want 10K firm. Good amount of leaks, hoses from the sun are shot, all 4 cylinders leak prettty bad, hrs are 3800 but not sure when the meter quit. It did have the SS track on it that was pretty good.

So, to heck with it, Ill keep looking. I find a 250c with about 1600 hrs on it, good hoses, few leaks, its been ran every few months on various jobs, it has that 573 DVT fuel hound in it. Big machine, maybe too big for clearing work and putting in a road. 46K LBS about so no permits to move.

One final drive does leak depending on how you park the machine shaft rotation wise. Maybe a bugger on the shaft? Bentshaft ? seal may be turning? Not sure. Owner says hes not worried about it and just adds gear oil and not spend the money to fix, re: oils cheap.

So Im thinking about it and will go drive it next week. Im gonna measure up the track and keep hunting for the track service limit specs / sizes.
Man I wish I would have saved them from RP when that guy posted them up.
But hoping someone on here has them as well.

I found this at General Gears site:

http://www.tractorparts.com/undercarriage.htm

Is a repro of IH chart guides, the 250 had 7.50 pitch rails, good luck finding replacements/parts as I am in the same boat with a Allis with 7.00 pitch.

Thanks for the link. Page under construction sadly, they only had the 25 and 9 track info. No 250c track info. CB

I think there was a serial number break where they went from 7.5 to 8" CC's They then called it a SS or severe service track and the rails were about 3/8 taller. Hopefully someone has a copy floatin around...CB

Go to the bottom of the page, there is "IH track school manual" lightly high lighted, click on that and you will find the 250.

Thanks DM. Yes I have that download, very good general infornation on IH. However does not give roller dia and flange heights etc. Hoping to find a repost from a reader on/from the IH track service manual. They listed all specs of every sort on the tracks.

With some luck maybe the right "packrat" will catch this thread. Thnaks again CB.....

Your final is leaking on one of the dowels, it has any oring on the inside the owner was right on "its just easier to add oil." If you park it so the dowel is at 12 oclock it will be above the oil level--I know these things because thats what I do with mine lol.

Thanks for the info 250.

IH 250C is basically the same machine as TD-20C dozer. The track pads will be narrower of course. The parts are going to be a lot harder to find for the 250C and for IH engine. The 175C was basically unchanged until it was stopped being produced in the 90's by Dressta. The only change was to a Cummins engine at some point in the late 80's. Make sure you find one with a 4 in 1 bucket. We did a conversion on a TD20C from the DVT to a 466 I believe and the engine mounts were the same. We have a brand new turbo for the DVT 573 that we never used that we have for sale.

Thanks for the info. I wound up going with a 175c, that 573 in the 250c was just too tough to find parts for. B

The pic is just after 2nd pressure wash. The guy/seller had just used it the day before to fix a pig slop pool and never blew it off. Boy was it nasty, a combination of clay, roots, and pig flop. There was no way it was going in the shop with clumps off that stuff falling off! I scooped up about a full skidloader bucket of goo after I was done. I wonder what kind of poop bath Im gonna get when we drop the belly pan?

Did the 466 seem to have as much power as the dvt 573?

Well they both barked good when working a load. I couldn't tell alot because Im a rookie and the conditons were different and a weeks time between them.

The 573 in a crawler app is suppose to have 57HP more. 466 = 133 573 = 190 I think they were both rated at 2400 rpm? Both units at about 3/4 throttle seemed to have more power then either had traction for. I bet in a dozer it would be Big difference.

Looks good Barky. Parts shouldn't be too painful to come by. You doing a full up service or gonna put it straight to work?

I think I better go over it first. I gave the motor and trans area a degrease and steam wash the other day. Prior I couldnt see or tell much as it was so crud covered. I did take it out in the brush and black locust to see how it would do for maybe 45 minutes. The ripper is gonna be great for the locust roots except I didn't want to use it much as its missing one tooth. The guys at romac are trying to figure out as to what teeth are on this thing. They think someone put cat shanks on the IH ripper boom. Hope to get fresh FD, engine, and roller oil in this weekend. I don't know yet if I should change trans and hyd oil or just the filters and run the exisiting oil?

Speaking of oil: I know many say you should run the factory specd 30W diesel oil in the 466 engine. Now all my other turbo diesel motors large and small spec 15w40 oil. Given the advances since 1982 wouldn't it be fine to run 15w40 in this motor as well. ???

OK what else, so Hytran in the trans and is it 30W in the hubs and also the lift hydraulic system? Just got a copy of the shop srvc manual but it didn't cover lubes oddly?


The opening on the ripper tooth (ID) is 2.5 wide and about 3.1 tall, I think it could go as tall as 2.5 x 3.4 if it rides further towards the shank shoulder

Don't blame you on freshening it up a bit. I'd recommend changing out the trans oil if you don't know when it was changed last - at least you'd know.

Here's the oil run-down
Engine - 15w40 (we used CaseIH oil and filters)
Trans - 10W Hytran (we used TSC Traveller brand which is Hytran compliant and complied with several other specs. We've had good luck with it.)
Hydraulic - 10W Hytran
Hubs - 80-90W Gear Oil
Idlers - 30W

On Edit: Regarding hubs, the manual recommends draining, filling with 5 gallons of diesel in each hub and running a few yards, drain and fill with oil. Put your nose plug on when you drain, then again it's probably no worse than the pig flop you've already experienced. Did you find anything of interest in the belly - was Jimmy Hoffa in there?

Can't help on the ripper tooth. I'm sure Romac can match it to something they have.

I switched over everything I own to Rotella 15W40 around 10 years ago, not dissatisfied with the results, actually saw a decrease in oil consumption on one farm machine as well easer to cold start.

Thanks for the info, you guys are great!

Had a bit of a start today. No oil on trans dipstick, YIKES, I took it out for a little test the other day and forgot to check it as I needed a wrench to get the cap off and kept forgetting it. Had good clutch pressure and TC temp so I guess there was enough oil not to kill anything? Anyway threw 2 gallons of 10WT non-det in it to move it back to the shop. It just touched the bottom of the stick. Arggggh.

Yeah, the rear has an appetite - 35 gallons if I remember. You might still be a few gallons shy.

I called the guys down at romac in AL about my ripper tooth search. Took them a couple days but they found the right ones. Gregg down there figured it out. I called 2 other places, one in Wi. and Il. and got the "well I dont see anything in the book" line. Nice job romac guys! Bucket teeth are almost shot, guess Ill get them there as well.
