Rear bearing race
Discussion
Bit of stuck and requiring help here...
I have taken the rear hub out of the car and dismantled the bearing carrier. The two conical roller bearings are out as well but I am left with the bearing races still within the bearing carrier.
Since the new bearings come with new races, I assume that I have to take them out as well (and I would like to do so in order to be able to zinc coat the carrier).
Question is, how do you press them out of the carrier? Is there a special way to do it?
Next question is, how do you press them back in? Is there a stop you need to press them against?
Do you need to press one from the front and the other from the back?
Are there any assembly instructions available on the internet?
Thanks for your help.

I did this a few weeks ago. ok you need s flat-ended punch and a hammer. put the hub on your bench. you will notice a 2mm gap between the inner edges of the outer shells that are inthe hub. You need to insert the end of the punch into the gap (at a slight angle obviously) onto the inner flat face of the shell. Tap one side then the other side of the shell (12 o'clock, 6 o'clock) continually, they will move around 0.4mm each side at a time. It takes a while but it's the only way.
re-fitting is the reverse.
I found heating the hub helped a bit.
I did have a full set of instructions but cant find them. will look....

The best thing for fitting bearing races is a nice bit of flat mild steel.
Ok if you're pressing them in but I'd go for something softer, brass or alluminium, if "tapping" them in !
, it splinters with repeated use and leaves fragments in the bearing. Sounds odd I know, but plain mild steel makes the best bearing drift.BliarOut said:

Ally, brass and copper are too soft and will splinter in a way that plain mild steel doesn't.I have been b
ked and then bked my apprentices for this very sin 
Like I said, you would think you're being more kind to the bearing using a softer metal but it doesn't work that way.
Hardened metal on hardened metal, good job you've never been involved in Health & Saf.... Oh.First important piece of info here: You can remove the two races by pûnching them out one at a time.
Second piece of critical information: When inserting the new bearings, since they are conical and have rollers instead of balls, is it ok to press against the outer cage to insert the whole bearing on the shaft first, then do the same with the second bearing, until it comes in contact with the first one, then press the bearing carrier on top of the assembly until hitting the stop? (note to self: don't forget the dust/grease seal before inserting the first bearing)
