S.O.L. on the 2090

Looks like I am out of luck on getting the 2090 Case back in service. That little 5/16 x 1 inch pin is no longer available from Case IH anywhere in Canada. :cry:
 
(quoted from post at 07:58:28 07/12/22) Machine shop make one?
Possibly yes but it is a special "grooved" pin that has to fit not too tight, not too loose. Too tight and you will never be able to remove that shift rail again if at some time the shift forks need work in the future. Too loose and it will slip back out just like it already did.
 
Is this a roll pin, or would a roll pin work? Any hardware store should hve them in stock. One trick to beef up a roll pin is to insert another pin or a nail into the center hole.

No it is a solid pin. A roll pin might work for a while but doubt it would last very long.
 
tractor wreckers ? westlock tractor parts 780-349-4832 , dean. a machine shop can make that but you need on as a sample first.
i must have missed what its for.
 
I'm just throwing out ideas, would grinding small flats on four sides of a standard dowel pin reduce the amount of interference area to be displaced?

Go to www.mcmaster.com and enter ''groove pins'' in the search box.

NOT sure if the ship to Canada???
 
(quoted from post at 08:54:46 07/12/22) Rusty do you have a part number for the pin? If so post it and will do some
searching when i get time
135-365 is all they list in the cih parts book. Not much to work with. The McMaster Carr site looks interesting and has a pin that might work. Should think there was a place like that here in Canada.

Can't imagine Case creating and using a non industry standard groove pin.
If it's location makes it possible I would put a hose clamp over the pin hole to keep the pin from slipping out.

If it is that loose in the hole maybe a new hole needs to be drilled.
 
Google "Mills pin"


Case didn't create special fasteners unless it was really needed.

Worst case, if you can't come up with any other method, cut off a bolt to fit. Then weld in place. The first pin went 40 years, this one should outlast you.

Who cares if it fits too tight? Even if you can't ever get it back out, you will get more use out of the tractor than you ever would if you just throw up your hands and junk the tractor today...
 
You might post over on the Case board where John Saeli might see it. He may have something as he has quite a parts inventory.
 
If a 5/16 dowel pin is too tight, get a 2 inch long dowel pin, drill a 5/16 hole in block of steel.

If a 5/16 is loose, get an 8 mm.

Put the dowel in a drill or drill press, add some valve lapping compound, start working it in the hole until
it is down a few thousandths. It will naturally taper up to the end you are holding in the drill.

Keep trying and fitting until you get the fit you need.

I don't see why it would have to have the groves, but they could be cut in with a cut-off wheel before
lapping it.
 

A grooved pin is not a pin with grooves cut into it.

The grooves are "plowed" into the surface, most commonly full length. And upset the metal beyond the surface of the mother material.
As the pin is driven in the tiny amount of upset metal due to creation of the groove gives the pin a force fit.
 

If you're concerned a roll pin isn't going to hold, how about a coiled roll pin? Obviously McMaster has grooved pins, but is the hole worn open to the point it wouldn't hold?

I'll agree that it's unlikely Case made a custom groove pin. There would be no possible reason to have a proprietary pin in that location...

I see Grainger in Canada offers a 5/16 x 1.25"... Could always dremel off the extra 1/4".

Yes, the Grainger site looks like an option. If I don't get around to replying to all the helpful suggestions its because I'm busy actually outside working but I will be back.

Lucky guy... Gets to be doing actual work while I'm sitting here at a desk bored out of my mind waiting on other people to do their work...
 
If it was made once it can be made again. Machining is much
more advanced than it was 40 years ago.

I am in manitoba and there are wreckers around here that would probably have that pin. My brother may even. If a different case as 1070 have
such I know at least 3 wrecked at his place I steal parts of of. my cell to text a pic of what you need and I will check around 204-526-0505
 
Please post a picture of this pin before you install it. I'm curious what kind of pin it could be. Thanks!!!!
 
Will this help?

Five different styles of grooved pins.

If you don't find an OEM pin or substitute, you might want to consider having a machine shop knurl a 5/16x1 pin or knurl your pin. You can control the amount of metal raised during the knurling process which will give you the amount of interference fit you're looking for.
 
Thanks again for all the suggestions and help. I think we have a plan to make one. My brother, during coffee and dinner breaks at work got together with the local
machinist and they are going to try and make a different type of pin that will hold the shift rail in place. I haven't taken any pictures or video of it today as
I've been busy spraying chem fallow. Just in for my ten o'clock supper now. Perfect day for spraying.

find someone with a lathe and have them knurl a piece of 5/16 rod. the knurl should hold the pin in place. if not a few drops
of 690 loctite should help it stay in place
 
Just take a 5/16 pin and put the grooves in it with a sharp chisel. In an oil environment inside a transmission, if you can
drive it in, it will come back out. And as Barnyard said, who cares.
 
No need to make one with a package of 10 from MCmaster Carr for 7.54 USD. 5/16x1 inch. 98400A125 is the part number you are looking for.
 
We had a hydraulic line break that feeds the brakes and clutch on our 1130 MF. Brought the broken parts into the local dealership and asked them to make a hose with the same fittings (1/4) and get it running
again. Turned into a huge ordeal. First they said the part wasn't available then they said they couldn't make it without the specs. We had the line in our hand but that wasn't what they wanted. Three days
that tractor was down until We finally found the part online (NLA) but found all the specs on it for the JIC ends and the like. Then they would make the hydraulic line. I am getting so tired of our
dealership I refuse to go in it anymore because I can't stand their parts people.

I could be facing the same thing on the 7130 magnum. It has a leaking low pressure return line for several years now and might be getting worse. Have not checked CIH availability but might also check the local repair shop. They made me new steering hoses for that tractor a few years ago and they worked find. No trouble at all.

That's about criminal... I can mail order custom hydraulic hoses in that kind of time frame. If I went in a shop and they told me they couldn't duplicate a hydraulic hose with JIC fittings from a piece in hand, I'd about loose it...
