I need a bit of advice on replacing wheel bearings.
I have just completed fabricating a 20 tonne hydraulic press and I have used it to press out the inner part of my front hub, the bit with the wheel studs on. It started to shift at around 10 or 12 tonnes I would guess.
The bearing inner ring is made in two halves and one half is still wedged on the shaft. I am planning on putting some heat into it to get it off the shaft, unless someone says otherwise. I tried a puller but I can't get the jaws under it (my puller is half knackered anyway).
The inner ring is hard up against the back of the hub and I can see a thin disk. Is this a separate dust seal that I need to retain or is it just part of the original bearing that can be ditched? I can't tell until I get it off. It had the original Timken bearing fitted, which was a double roller bearing with a nylon cage.
I have also removed the circlip and pressed out the rest of the bearing from the outer hub. It was tight, right at the limit of 20 tonnes I would guess before it made a bang and started to move.
Reassembly? After cleaning up the hub I was going to press the bearing into the outer hub first, by just pressing the outer ring. Then fit a new circlip and press the whole thing onto the hub shaft, pressing on the inner ring only. Any comments appreciated.
I also notice my replacement is a ball bearing marked SAHA.
