th350 rebuild quick question
« on: November 13, 2024, 04:31:32 PM »
I have Cliff's th350 book, but didn't see this addressed. For my cruiser street car, I'm trying to rebuild a th350, BOP style, probably about a 77 model. It has the torrington bearing, and has the "steady-rest" style stator. My rebuild kit comes with the sealing rings for the stator, and gives me a choice of "scarfed" teflon seals, or metal interlocking ones. So, that's no problem. It had teflon, so I'll just go back with them. So that takes care of the 5 oil sealing rings, but I also have that 6th bottom ring slot in the stator for the steady-rest ring. But I see no steady-rest rings in my rebuild kit. It's a very complete kit otherwise, so kind of surprised that it's not included. I still have the old steady-rest ring that I took off it, which actually still looks pretty good. It's a whitish color. It has square cut ends, so just butts up to itself. Don't know if it's teflon also, or maybel some kind of urethane. I read in the Ron Sessions book that they vary by color, like purple, green, white, yellow, depending on ring depth size, and he gave measurements. So, mine matches up with the white one. I could re-use the old one since it's in good shape, but wondering if new ones are available somewhere? Thanks.

Also, I have another BOP th350 steady-rest pump that's missing the plastic steady-rest ring. What do you do when it's missing? How important is it to have it? Thanks.

If it's in good shape I'd put it right back in service. 

Not sure if they are available anywhere these days.....

Thanks Cliff. Yes, I'll re-use the old one on that pump. I have looked high and low for a new one for the pump that has it missing. I even found the GM part number to search for it. But all the trans parts sources say discontinued. So, I'll just have to find another old pump with one on it I guess. You've pretty much verified what I've found, which is new ones can't be found. Thanks again.
