Re: "Basics of Basics" top pump/motor disassembly and rebuild.

Was there a typo? Just wondering in the writeup the op said he used break fluid in the system?? I've always used trans fluid but hydrologic oil from tractor supply will do also. Would think break fluid was the cause of all that crud in the pump and cylinders in the first place seeing it absorbs water.

I said I used automatic transmission fluid in the original post of the thread. They originally used brake fluid.

I thought you had originally used break fluid. I saw where you changed over to atf. Was that actually used from the factory or did a prev owner do something stupid. It looks like it did a hell of a lot of damage considering my system is all original and works great knock on wood.

Re: "Basics of Basics" top pump/motor disassembly and rebuild.

I tried to use it with the brake fluid because that is what it used originally as I remember. I don't remember now but I think that is what I found in my study of it. I tried it, the pump didn't work, and that is when I pulled it apart as shown in this thread. I then after cleaning it up put the ATF.

But as I remember there wasn't much to think about, they used brake fluid, from what I remember when the car was new.

Thumbs up Re: "Basics of Basics" top pump/motor disassembly and rebuild.

AWESOME great addition to this thread. I seem to have seen it before, is it in the regular body manual? I should have posted it if I have seen it, thanks for doing it.

Re: "Basics of Basics" top pump/motor disassembly and rebuild.

So in a nut shell, there is NO rebuilding the cylinders? Correct?

It is certainly not impossible, I just don't see a good reason to jump into it personally. The replacement seems the way to go but you could give it a try.
