Where would you send them? Someone's got to be repairing these things because mechanics are still using them. At least there might be a direction I can go to figure out how to fix this stuff myself.

So, for context I was gifted some tools that were my grandfather's when I visited my grandmother back in June. I posted here looking for information on the engine his valve-cover-clock came from last year. He was an engineer at Porsche for almost 30 years for anyone who doesn't remember that thread. He also did a side hustle at the race tracks as a mechanic from what I've been told.

In that container there was an Ingersoll Rand air saw that I'd love to be able to use, but it looks like at the minimum the seals have swelled and/or dry rotted. The dog bone valve has a lot of resistance to movement, and I think I need new o rings. Would you use Viton or something else? Why?

(While looking I found either a repair slip or receipt from IR in German listing Porsche as the billed party. Super cool.)

I also have a air impact of equal age roughly (also from the same box), and it leaks some but functions okay. Just about the only thing that works fine as far as I can see is the 3/8" air ratchet.

While I'm at it, I'd like to explore getting an old Hazet 1/2" wrench spruced up as the backlash is AWFUL but I genuinely believe there's at least another 30 years in that ratchet.

It should not be hard to find rebuild kits or rebuilders for IR Air Tools. You'll need Model #'s & Serial #'s to get started.

I can't vouch for Ohio Power Tool on anything but IR accessories, but they do in house repairs --> https://www.ohiopowertool.com/service

I'd start here for the Hazet Ratchet you want to freshen up --> https://www.kctool.com/

You might get lucky, but you might need to identify the rebuild kit P/N first though. Again, Model # and S/N of the Ratchet will get you started.

That said, as your tools are 'older' you might need to consult with the manufacturer.

The tools are most definitely old enough to have been updated and given new part numbers. To make things worse it's the international version of the tool. I'll still reach out to them to see if they can help though. Thanks.

I'll check out the site for the ratchet.

Parts may be out there, but as has been stated the model number is a must.

I've rebuilt several impact wrenches that were 20-40 years old. Soft parts are/were relatively easy to locate, some hard parts not so much. I think it took me 15 years of off and on looking to find (read find on eBay with blind luck) an anvil for an old CP 3/8 impact wrench.

Currently looking for parts for an old Matco 1/4 air ratchet that is so old Matco can't positively ID it.

I had purchase a Snap-On Air gun back in 1989 and at the time paid $450 for it. Around 8 years ago I had them replace all the gaskets at a cost of $125. The gaskets are again dried out and loosing air. To me it is not worth getting fixed again. I'm just going to stick with my battery powered Rigid and Millwukee fuel.

I have the box and everything for the saw and (I think) the air ratchet. Right now I'm considering going battery for the ratchet (and will if I catch one for a great price), as I'm pretty heavily invested in the Kobalt 24V ecosystem already, and I just bought a Milwaukee M12 right angle die grinder (apparently the only one on the market) for weld prep.

Really, out of all the air tools, the one that I care about fixing the most is the saw. I'm actually wondering if the rebuild kits for the updated tool will work on the original.

Update on my Matco ratchet rebuild project. Matco tried but could not help me ID my ratchet (not model marked).

A little back and forth with these guys: https://powertoolrepair.com/ and I managed to get a head kit for $20 delivered.

I was originally told to order one P/N based on an ID from some pics I sent of the ratchet. It ended up being the wrong parts as their initial guess at ID was close but not perfect. They ate the return shipping on that without even being asked.

Correct kit showed up yesterday after PTR pulled several head kits and took apart a couple of ratchets to make sure I got the right stuff.

Above and beyond for $15 in parts and $5 shipping in my opinion.

I worked for IR for 26 years and at one point was responsible for the air tool repair center in Elmhurst Ill. We had 8 full time mechanics that did nothing but tool repair.

That repair center is gone, but there a dealer that does such work. It's Industrial Tool Products, Wood Dale Illinois (suburb of Chicago) Link
