I insisted to pay them more, they said no, it literally took them a few minutes, most of the time was being heated and cleaned in the bath. Best part, my turbo S hubs were clean, undamaged by forcing things, and are perfect. Maybe there is a shop near you who can do the same thing?
I would love to find a place like this. I paid a guy $50 A HUB to remove & press races that are on my car now (I installed the hubs of course). We don't get the same service so easy around here

Dare I ask.. what do you use the angle grinder for??
Oh *that* Jurgen!

Well I did something similar to try and press control arm bushings. The problem was, the rod snapped in two. So I thought, I know, I'll use a grade 8 threaded rod. That won't break, right? Well as the saying goes, now I had 2 problems. Instead of snapping, the threads simply stripped, leaving me with the bushing half way in and no way to remove my ridiculous broken DIY press. But since I used a grade 8 rod and nut, there was no cutting them off with a hacksaw. So I had to go shopping for an angle grinder just to get back to square one!

Of course this didn't happen to Jurgen because he's not an idiot like me, and I see he specifically mentions in the video that he knows the threaded rod is good for 5 tons or something. The one I used was probably an Ace Hardware 10mm threaded rod or something like that.

Any transmission shop would be able to do it easily. They regularly clean transmission cases, etc. Or a radiator shop maybe. I didn’t want to damage turbo S hubs, they are really difficult to replace.

In any case, good luck. It was just an idea that I thought you might be able to take advantage of.

Too funny! In retrospect that is lol

Ok.. now to find a suitable fine-pitch 16 x 1.5 "spindle" that can take 5 tons...

I used the same kind of bearing kit for my front wheel bearing job. I heated the hubs and cooled the new races before tapping the races in. I used a stout hammer and had to wack pretty hard before the sound of my hammering changed indicating that the race was seated. So like @thomasmryan the sound change was my indicator that the race is in place.
I do remember that I had to support the hub on a very hard and sturdy surface before my hammering started to count. I used a steel plate on a concrete floor. There must be no give in that surface otherwise the support absorbs the hammer blows rather moving the race into the hub. Good luck.

I haven't had much luck walking into shops around here asking for anything. They are either very busy, want big money, or just don't want you around. It's a big city with few places I guess. Or maybe I'm just not going to the right part of town. Yes, good idea but it seems here you have to "know" somebody... which I don't. Transmission shop is a good tip though. Might try and walk into one of those.. if I can find them!

What I ultimately ended up using for the control arm bushing was something like this.



Basically the same thing I tried to make, done properly. I may or may not have availed of Harbor Freight's unofficial "tool rental" program

Dan, when I did my front bearings I put the races in the freezer for a few days. I'm not sure if 1hr will "shrink" them enough. With my hubs heated in the oven and frozen races, mine literally dropped in with a slight tap of the hammer and bearing driver like the one you're using. You shouldn't have to grind anything.

I'm really just reading this to learn but I also think that similar to what @951Tom said, cold will be your friend.

You're most of the way there at this time of year with where you live but I think that if you put the races into some dry ice for a bit you'll have an even easier job. Might save you some aggravation and pounding on parts.

Good luck

What is the oven temperature setting?

I have decided to make the Jürgen Press. I can drill out the centres of the key bearing install pieces I have and then source the proper threaded rod with nut. Not so easy atm with the lockdown but I'm in no hurry.

I like the press a lot; I don't turn wrenches for a living or work in a mechanical fashion and just don't have experienced hands for the hammer in this application. The press seems much more forgiving! Plus it's very by-the-book.

These are spare hubs so I have some time. Running an old car requires a machine shop lol

T&T Racing, can't remember exactly but I think 150-200F for an hour+. I remember I had to use the wife's oven mitt to handle it and she wasn't too thrilled about it all lol
