Dan6061 Posted February 2, 2007 Report Share Posted February 2, 2007 (edited) Put my new bug bearins earlier, all fine and dandy.As I tighten it up in my frame, I get it as tight as i normally do, and the cassette dtiffens up?I take it out the frame, put the bolt in the non-drive side, and twat it with my rubber mallet, and it feels free and 'normal' again. Then it does the same when I tighten it.I'm certain that i've got it all in right.Goes:End -- Driver - driver bearings inside (4) - little spacers - Hub bearing -----axle----- Hub bearing -- End.I guess there isn't any spacers or anything inbetween the hub bearing, and driver?There was so many broken bits coming out when I broke the old bearings...Anyone know why it's doing this? EDIT: Found two little spacers, so I put those on, on the drive-side, inbetween the driver, and bearings.Now when I tighten the bolts when it's in the frame, the driver still stiffens up?But when I loosen the bolts, the driver loosens off too? Please Note: The bearings are the exact same as the old ones. So same ID, OD, and width etc.The (model?) number on them, matches what the guide on Profile's website says. So yeah, got the right bearings. Edited February 3, 2007 by Dan6061 Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted February 3, 2007 Author Report Share Posted February 3, 2007 Bump. Put it on the bike last night, and rode it around, it was fine forwards, and it engages properly...Just when you turn the cranks backwards, it feels like the chain is mega tight, when it wasn't?Then, when I loosen off the hub bolts, it feels fine again.

matt rushton Posted February 3, 2007 Report Share Posted February 3, 2007 Not sure if this will work, but try putting a little washer on each side of the hub in between the hub and frame and another in between the bolts and the frame.Matt Rushton Quote Link to comment Share on other sites More sharing options...
basher Posted February 3, 2007 Report Share Posted February 3, 2007 End -- Driver - driver bearings inside (4) - little spacers - Hub bearing -----axle----- Hub bearing -- End.i think it should go 2 driver bearings spacer 2 driver bearings if i remmebr rightly that may be your problem.

It might just need bedding in?The engagement works perfectly, better than before even.It's just the driver getting stiff that's the problem..it's like it find some viagra when I tighten the bolts..

PaRtZ Posted February 3, 2007 Report Share Posted February 3, 2007 Well in the driver that spacer bit SHOULDN'T come out. Its so annoying when it comes round to changing the bearings because you cant knock em throughDo you have the bolt spacer things too? They should have a small black washer on them. On the driver side especially they should go on there, so that the driver isn't touching the dropout at all and its only the fun bolt spacer thing that does (Which comes into contact with the ID of the driver bearing I think) Its hard to explain, but that helps It sounds like something is flared though. Either the axle at one end or the bearings or the driver or something else. If its not becoming loose straight away after you undo the fun bolt then its being compressed on and then getting stuck (due to the flaring) Take the hub out and see if the driver has any play first of all. And then see if it will come out smoothly. Check the bearings for damage or bits of crap and give it a clean anyway. Check the ratchet ring too, maybe its moved and is slightly tilted?Sorry that thats quite generic but its not a problem ive heard of before. If I think of anything else Ill post up PaRtZ Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted February 3, 2007 Author Report Share Posted February 3, 2007 Just typed everything out..and lost it. Right...Bolt spacer things? - The bits that press onto the end of the axle?I have those.The driver wasn't touching the dropout.Do I need a spacer on either of those end caps? I have two small, wafer thin spacers, and i'm not 100% sure where they go exactly.I've got the hub bearings, and axle in place. I then put both spacers on the axle, followed by the driver.So inbetween the hub bearing and driver bearings, are these two spacers.I don't think the axle is flare or anything, the end caps come off and on fine, and it's still round from what I can see. The driver doesn't wobble at all once it's all on. It feels perfect, untill I tighten it up in the frame.Then the driver stiffens up, and feels like the chains really tight, so it doesn't freely spin backwards...And..erm..Ratchet ring? :$ Quote Link to comment Share on other sites More sharing options...

There maybe a couple of washers inbetween that are like 0.1mm thin but definitly not 1mm thin washers. If those washers you have are black then they go on the outside, touching the head of the fun boltsThe ratchet ring is the circular bit inside the hub which the driver pawls ratchet against.

Dan6061 Posted February 3, 2007 Author Report Share Posted February 3, 2007 (edited) I said 0.1mm washers?Didn't I? No I didn't...but they're the 0.1mm ones.Just a thought...do the driver bearings just need to bed it?I rode with it earlier..and it all seems fine, engagment wise etc...

PaRtZ Posted February 4, 2007 Report Share Posted February 4, 2007 When I replaced my driver bearings they worked straight away thing is the driver shouldn't tighten up because its not on a taper (ie the more you tighten the further it moves up a taper) of any sort. If you do manage to sort it let us know Quote Link to comment Share on other sites More sharing options...

If you do manage to sort it let us know When you replaced yours, did you have the little washers (0.1mm ones)? I only have two...so I put them both inbetween the Hub, and driver bearings...Is that right?I know the driver shouldn't tighten it up, but i'm hoping it'll sort itself out. I've had enough of fiddling with it, the engagement works fine... Quote Link to comment Share on other sites More sharing options...
26inch Posted February 4, 2007 Report Share Posted February 4, 2007 try and find an exploded view on the profile site or something. It certainly sounds like some of the spacers are in the wrong place, thus when you tighten your hub the bearings are being crushed, i would ride it while its like this or your just going to kill the bearings real quick. Try looking at another profile, or try loads of different spacer compinations until one works. Try and think logicaly and work out if the bearing would be crushed when you tighten the bolts Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 4, 2007 Report Share Posted February 4, 2007 My brother's Profile did the same, and all it was was that the shelf on the little cap bit that goes between the driver and the dropouts was worn down, so instead of just butting up against the bottom bit of the bearing, it rubbed on the top bit of the bearing race too, and the actually mid-section of the bearing, so all he did was just get someone to machine it down a bit so the shelf is reinstated. Maybe the same thing with your's? Just look at the end cap bit and see if it's like an L-shape or whether it's totally flat? Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted February 4, 2007 Author Report Share Posted February 4, 2007 (edited) Oh right, nice one Mark.You mean the silver end cap yeah?Right...It had a little bit that stuck out, but I thought that might be what's causing the problem, so I sanded it off. But it's still doing the exact same thing as before, when it had the 'shelf' bit.. I can go to the industrial estate during school, and ask around if they can machine it back to normal if it's needed...I have a washer that I can out there, if it did need to stick out a little bit...but still, tried that, doing the same..stiffening up the driver.

A!! Posted February 4, 2007 Report Share Posted February 4, 2007 The problem your having is exactly the same as the one i had with my freecoaster.It turned out that it was the cone shaped washer that was forcing against the driver bearings when i tightend the axles up, meaning it made it very hard to turn the pedals round. So i took the the cone washer off, and flipped it the other way round so the smaller diameter bit was sitting against the driver, which stopped it from rubbing on the middle of the bearing, so it now sits on the metal ring.

AdamR28 Posted February 5, 2007 Report Share Posted February 5, 2007 Goes:End -- Driver - driver bearings inside (2) - Steel Spacer - driver bearings inside (2) - little spacers - Hub bearing -----axle----- Hub bearing -- End.You've got a spacer missing - should be as I've listed above Ads Quote Link to comment Share on other sites More sharing options...
Tim-Rodriguez Posted February 5, 2007 Report Share Posted February 5, 2007 Yeah i had exaclt the same problem...I managed to sort it by putting the silver end caps into a hand drill and shaving off the metal with a knife so the metal touches the center of the bearing and not the back plastic cover of the bearings when it tightens.

Dan6061 Posted February 5, 2007 Author Report Share Posted February 5, 2007 (edited) You've got a spacer missing - should be as I've listed above AdsOhhh right..So is the 'spacer' the one in the picture I posted above?...or is it completely different?Can you get hold of them? - or shall I ring Profile? EDIT:Nevermind!Rang Profile, and he's sending me the spacer. Edited February 5, 2007 by Dan6061 Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted February 6, 2007 Author Report Share Posted February 6, 2007 Arghhhh....Got the spacer for the driver this morning. Put that in, all fine.Got everything in the right places, it's exactly how Tarty Adam told me...Yet it's still locking up when I tighten the hub bolts?

AdamR28 Posted February 6, 2007 Report Share Posted February 6, 2007 Got the two slim spacers between the driver and hub shell bearings on the drive side? Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted February 6, 2007 Author Report Share Posted February 6, 2007 (edited) Ok.Built it up properly, it did the same as before.I took it apart, and rebuilt it (exactly the same as before)And now it works fine. Note to self: Don't loose bits. Cheers to everyone that's helped. Guess it can be closed now. Edited February 6, 2007 by Dan6061 Quote Link to comment Share on other sites More sharing options...
