Tool for Removing USD Spring retainer?

You know the one on the first stage that is open to the environment? What do you use for that?

If you are talking about the external and internal snap rings, I use a pair of good quality snap ring pliers. Don't go cheap on them, the cheap ones are not up to the job. I have this pair from McMaster Carr #5391a34 . Do a search on that number at this site . McMaster-Carr

If you are working on any USD regs, you will also be doing yourself a big favor if you buy the HP seat installation tool. USD part #111000. It's around $15 and worth every penny. You can assemble the HP stage without it but it is sooooooo much easier with the tool.

And the dowel. Don't forget the 1/2 inch wooden dowel.

edit:
See page 5, steps 14 and 15,
and page 7, steps 13 and 14 of this:

to see if we’re talking about the same thing.

I meant the intermediate pressure spring adjuster.

But since I am looking at a SEA first stage, I am looking at two of them. one for the spring block, and the other for the adjustment screw.

I know you can use a large screwdriver, and I ground down a chisel before. But maybe there is something smarter to use.

Since I went to Harbor Freight for the ultrasonic anyway, I bought a bench grinder to make some tools. I am going to destroy a set of chisels to make a tank tool and a big ole screwdriver.

While you are at it, buy a cheap 1" wrench and carefully grind out the middle section to make a deep 1" wrench for taking off yoke nuts.
