I'm trying to replace the o-rings in my super a hydraulic block but i can't get the check valves out. Any ideas would help. The piston was leaking bad so i thought i would change all the seals and o rings. In the parts book its 13a and 16b thanks for any help

xj, I got lucky. I had this piece of rubber, a cap off something, that I slipped over an allen wrench. Then I stuck it in, torqued it sideways so it would 'grab', and then pulled them right out. It covered the end of the allen wrench, so I didn't have to worry about dinging any of the internal bore surfaces.

In this picture, you're looking at #26, the 'pressure regulator valve seat', which is threaded in place. I got mine out by getting that 'drag-link socket' from NAPA, but again, you have to be able to put enough force on it, while unloosening, to make sure the blade doesn't slip out of the slot and ding the bore.

Somebody else, I think tractorsam, made this next removal tool by grinding down the head of a long bolt so it would fit in the bore. By cranking down the washer and nut, the rubber spreads and grips. The double-nut on the outer end serves as a handle.
Let us know how it works out.

Thanks for your help. I had a round head bolt from a leaf spring pack and a 5/16 I/D hose that fit tight enough to pull back out with a slide hammer on vise grips. While I was cleaning eveything I noticed some of the seals in the parts book are not on mine. The #10 ring seal and the 15a. I will try to post a picture when my son gets home. thaks again for the help
