Hi,
I've read a few topics on here about FSR bearing removal and how much of a world of pain it is.
Last night I changed all the other frame bearings and am now onto the FSR nightmares.
I've read you can use a 6mm centre punch. Anyone tried this? Is it a case of smack it through and hope it wedges onto the bearing and pulls it out?
The guy who used to make the removal tools hasn't posted on here for years. Anyone know if he's still around?
Or does anyone have one of his homemade tools?
Thanks for your help
🙂
to do the job 'properly' you need a blind-bearing extraction kit.

or you could try and get lucky with a screwdriver/expanding bolt/magic wand.
To remove the small rear bearings?

PS I have a blind bearing puller, and you can't use it to get the bearings nearest the wheel out, as there no space between the two back to back bearings
Nice one ^^^ 🙂
what's the bolt size? (or whatever will fit through the bearing middle hole)
Can you use the above/blind bearing puller to get the outer bearings out and then a normal bearing press on the inners (as the outer ones will be out of the way)? (hope that makes sense)
bolt size, errm m5? Whatever size fits through a chainring nut and a V-brake nut , as thats what those other bits are. I looked but couldn't see there was space between the two bearings to get the blind bearing puller purchase. The tool ^^ has to be position so it expands inside the bearing, without over lapping into the 2nd bearing & then bashed out with a hammer
You have to drill out the end of the V-brake nut?
Once all this is put through the bearing, is it just a case of tightening it until the bearing pops out or do you tighten it in then whack it with a hammer?
(just want to get the technique down before I go and try it tmw night)
Would you say it's impossible with a blind bearing puller? (due to no space to get purchase)
EDTI: looking at your 1st pic above. Is that how it'd be pointing if you standing behind the bike and were to be removing the outer right hand side bearing?
Noooo drilling, just the saw the cross into the chainset nut so that it can expand. So yes, fit it into the bearing then tighten it up as much as you can (as surprising amount) then hit the tool with a hammer, to pop the bearing out. Undo the tool and repeat with the 2nd bearing, the move over to the opposite side and start again.
Yep I have a BB puller and if I could have used it, I would have... been a while but I pretty damned sure this was the case. The two bearings each side are back to back but have a tiny lip inbetween, so you can't push them out together, but not enough gap for the BB puller jaws to fit into IMO
EDIT: Yes, to the direction..
Thanks for all the help. 🙂 Much appreciated.
Will report back tmw with how it all went....
Not sure what the pivots on the FSR look like and how easy they are to access but I found some boiling water a great help in removing my bearings from my Lappy Pivots. 😉
So.....
I tried the above chainring bolt method.....couldn't get it to work. The chainring seemed to have to expand too far before it could get any grip.
I tried last night with a hammer and screw driver.
Tonight I tried a bigger hammer and a bigger screwdriver.....result! Bearings out! 🙂
All bearings done and rebuilt. Still got a tiny bit of play in the rear shock mount though 🙁
😀 fair enough, imagine it must have been awkward to get purchase, to knock them out, that said they maybe bigger bearings than the one I changed, if the 'tool' couldn't clamp the inside surface
The shock movement will probably be the bushings, buy a tool with a couple if bushing for a £10 off ebay. Test the bushings for play by feeling the shock mount, whilst lifting the bike by the seat (only slightly, not up into the air).. If the movements there, needs new bushing (sorry if your already know this)
Yeah I think the bearings I was trying to remove were too big for your tool. (wasn't trying to say it was cr*p) 🙂
The rear shock mount has a sealed bearing either side of the shock mount (newly replaced) and then a plastic thing and a washer (to fill the gap either side of the shock mount/between to frame mountings
I've read something about the bolt not being long enough so it doesn't actually tighten all the way. Tried searching for the link but can't find it now...
