#17: Re: Help - fitting new rear bearings on drum brakes not disk. Author: kandlbarrett, Location: SwindonPosted: Sun Jun 16, 2013 11:23 am ---- Well, I have always wanted a Dremel so have used this as a excuse to buy one. I haven't attacked the snap rings with it yet but will report back when I have.
The use of these snap rings really is one of the worst cases of forcing someone to use the "stealers" (dealers) that I have ever witnessed. Though I guess if a snap ring is only half penny cheaper than a conventional circlip then with (according to wiki) 7,775,482 Peugot 206s manufactured that is a tidy saving.

I started with a drift and hammer blow. Migrated to threaded bar and sockets.
Upped the anti to using threaded bar with sockets, heated hub and "freeze-it" spray on the race but not a single bit of movement; I have never had such trouble changing a bearing. The nuts that I have on the threaded bar are quite long, the equivalent of four nuts and I was tightening them so much they have slightly deformed the threads.
I am thinking either main dealer or engineering shop to press them out or buy new drums and fit the new bearings to the new drums. My worry with new drum option is if the outer race is that tight how will I press it in?
Never have I been beaten before but these rear bearings are proving very troublesome.

Run a bead of mig weld around the middle of the bearing race, when it cools the race will shrink & crack
#20: Re: Help - fitting new rear bearings on drum brakes not disk. Author: kandlbarrett, Location: SwindonPosted: Tue Jun 18, 2013 2:45 pm ---- Stuck is an understatement. I would estimate I was putting 200+ft.lb onto the threaded bar (creaky tight and then even more turns on the nut) and not a single budge from the outer race. I even checked that there wasn't any snap ring left in place.
As before I have never been beaten and bearing races aren't usually anywhere near this tight. It is a first for me.
Thank you for the suggestion about a bead of mig - I have never heard of that one so will give that a try.

Needs to be a full bead of weld around the race of the bearing, as it cools the bearing race with contract & should crack / split allowing it to be knocked out easily.
#22: Re: Help - fitting new rear bearings on drum brakes not disk. Author: kandlbarrett, Location: SwindonPosted: Tue Jun 18, 2013 2:56 pm ---- I hope it works. The rear bearings on these have a very large outer race because the outer race is a single common race for both taper bearings so it is much thicker in the middle and twice as wide as most other bearing races.
#23: Re: Help - fitting new rear bearings on drum brakes not disk. Author: Fifer, Location: FifePosted: Tue Jun 18, 2013 3:06 pm ---- I put the old bearing inner piece in. Stuck a socket so it fitted on the race and belted the hell out of it. Took some hammering and it split the reace but out it came. I then used the old outer race to persuade the new bearing in.
#24: Re: Help - fitting new rear bearings on drum brakes not disk. Author: kandlbarrett, Location: SwindonPosted: Tue Jun 18, 2013 3:19 pm ---- Fifer: tried that with a 2lb (0.5kg) lump hammer and like you I have broken the inner bearing - read the whole post and you will see there isn't any "normal" procedure left except hydraulic press or the ring of weld that MrBSI suggested.
Thanks for the suggestion though.
#25: Re: Help - fitting new rear bearings on drum brakes not disk. Author: gazza82, Location: South BucksPosted: Wed Jun 19, 2013 3:13 am ---- Why not just buy two new drums with bearings already inserted?
#26: Re: Help - fitting new rear bearings on drum brakes not disk. Author: kandlbarrett, Location: SwindonPosted: Sat Jun 22, 2013 7:18 am ---- Bead of weld did not work (bugger.)
Attacked again with threaded bar - still no luck.
Daughter needs her car urgently (apparently.)
Purchased new drums at £64 per pair (I don't think you can buy drums with bearings already fitted.)
New bearings installed into new hubs with threaded bar and they were exactly the tightness I would expect and went in really nicely. Job done.
This job should have been a piece of cake; i still don't understand why the bearing is seized so tight. Still I don't have time to dwell on that but I do hate being beaten.
#27: Re: Help - fitting new rear bearings on drum brakes not disk. Author: gazza82, Location: South BucksPosted: Tue Jun 25, 2013 8:26 am ---- Don't new drums come with the bearing pre-fitted? .. wouldn't that be the quickest and simple option?

#30: Re: Help - fitting new rear bearings on drum brakes not disk. Author: eddie206, Posted: Tue Jun 25, 2013 9:29 am ---- Just incase someone else has the same troubles ,for the circlip removal would it not have been easier and cheaper to get a small pick or two(like dentists use with the 90°head bent over)and jam the circlip on one side while prizing the circlip out on the other side..
just force the 90°head behind the circlup then prize/pull the thing out by dragging it round behind the clip while the far end is jammed to stop spinning uncontrolably...
Im sure ive seen the tool at halfords in the small hobby tools section...if yours has one??
