davidbarr Posted March 22, 2012 Report Share Posted March 22, 2012 Okay, so I'm pretty sure my bearings in my Echo TR rear hub have started to get a bit of play as i can push the rim side to side and this causes the pads to rub on the rim when any pressure is put down on the pedals. How do I dissasemble my hub to get the bearings out and reassemble it with the new ones in? Am I okay to buy cheap bearings such as these or am I best to buy the Try All ones from tartys? Thanks.

Greetings Posted March 22, 2012 Report Share Posted March 22, 2012 The bearings in Echo hubs are of a cheaper kind, no need for anything fancy. You'll find the number on the bearing. To disassemble the hub you need to twat the axle from both sides. Best if you screw a bolt in and twat that rather than the axle directly. Reassembly is a bit more difficult without the correct tools, I find it easiest to install both bearings simultaneously. The bearing on one side needs to be resting against a flat surface (I use a vice) and the other you need to gently bash in either by placing both hub spacers on one side and hitting them, or through some kind of pipe which will rest against the outer race of the bearing. Once they're almost in you can install the wheel in your frame and tighten the bolts till the bearings are fully in. Quote Link to comment Share on other sites More sharing options...
davidbarr Posted March 22, 2012 Author Report Share Posted March 22, 2012 Thanks, doesn't sound too hard. Shall go and order some bearings Quote Link to comment Share on other sites More sharing options...
ooo Posted March 23, 2012 Report Share Posted March 23, 2012 I changed my echo tr rear bearings with some ones of ebay for a quid. there is a shim on either side of the hub holding it together (just wedge a srewdriver in it) surprisingly the wikipedia page about hubs was really useful. the rest is like greetings said, twat the axle proper hard.

Chris Borneo Posted March 23, 2012 Report Share Posted March 23, 2012 (edited) Not familiar with this particular hub but would it be possible to reinstall the bearings using the axle with a big thick washer on each end? Bit like a headset press. Save twatting a new set of bearings with a hammer. Edited March 23, 2012 by Chris Borneo Quote Link to comment Share on other sites More sharing options...

JD™ Posted March 23, 2012 Report Share Posted March 23, 2012 Would put inwards pressure on the centre race of the bearing with nothing supporting it on the other side. So no. I'll bow down to superior knowledge, but surely a big enough washer to cover both races of the bearing and thick enough not to flex under the required pressure (or multiple washers) would sort that?

My bad, just thought about it and yes it would work Edit: Really need to think things through before I type......

davidbarr Posted March 23, 2012 Author Report Share Posted March 23, 2012 Is there any possibility that the play could also be down to a worn axle? Quote Link to comment Share on other sites More sharing options...
Chris Borneo Posted March 23, 2012 Report Share Posted March 23, 2012 (edited) Yeah, I could have explained it better a big enough washer to cover both races of the bearing and thick enough not to flex under the required pressure This was what I meant by big thick washer. Is there any possibility that the play could also be down to a worn axle? Would have thought it's unlikely. If it's all put together right, the axle shouldn't wear.

davidbarr Posted March 29, 2012 Author Report Share Posted March 29, 2012 Okay guys, I changed the bearings and it was pretty straight forward but I still have the same problem. Beginning to think it's not the bearings because the wheel never really shook side to side, you had to actually push the rim to get it to move. Can anyone think of anything else that could be causing this? The spokes are pretty tight so I can't imagine it could be flex from there.. Any help appreciated.

err Posted March 29, 2012 Report Share Posted March 29, 2012 do you mean that the hub moves side to side on the axle? Quote Link to comment Share on other sites More sharing options...
