My sentiments exactly! Never hurts to know... keep it in the back of the thought locker.

Like I say, later this evening, once the rebuild kit has arrived, go pick it up, and do a little tutorial of assembly. Because if anyone noticed I didn't talk about what the little ball bearings do. Or where they go.
I'll include that part in the reassembly.

OK also meant to post this, kinda a demonstration for you guys, where the fluid flows on left and right turns. You can port into the vein for right turns like I did, or at the cap.
With the cap, it's aluminum, and cast aluminum, I've heard about it cracking, just a FYI.
I ported at the vain because flow from the rotary valve passes right by that port before it makes it to the cap resevour.
Just a piece of info.

So everyone knows, I haven't bailed on the write up yet, the dummies at oreillys didn't get my rebuild kit in today, have to wait until tomorrow

I would have been the guy that drilled and tapped into my assembled box and cleaned it out best as possible. But I can't do that now because I would be a ******* that was warned beforehand, lol.

Man, I wouldn't advise it lol, there's so many little cavities, ports, veins and everything else cast iron can get into. What makes cast iron bad is, it'll turn almost in a dust when machined. That **** will get everywhere. Especially in the rotary valve.
(hint hint that's one of the things you modify for increased fluid flow)

I've been told the tolerances are farily critical too. Seems all it would take is for 1 or 2 small shavings to get in there and start scaring up bores and tearing up seals to where failure wouldn't far away.

It could still work better than the average reman box, lol.
I don't remember exactly where the ball bearings go, but I know there's two different sizes that you really can't tell by eye.

Great Thread !!! I've edited the title and taken away the form of a question and gave it a correct title. Also Stickied it in the Lifted Steering and Suspension section so it can be easily found.

Those bearings aren't important. When they fall out, just throw them away.
On 2nd thought, maybe not.

Like I said, I'm covering the bearings and their function later today hopefully lol. This isn't done yet.
I was gonna wrap up the post with a re-assembly but like I said, those dummies at oreillys didn't get my rebuild kit in yesterday [emoji58]

They go in this tubular 2 piece "cage" they're what ride between the plunger and the worm screw that's on the bottom of the rotary valve. They are 2 different sizes (some of them) putting that back back together without it falling apart is a PIA
