My rear EX1750 wheel bearings seems to have given up the go, after much DH abuse it's now developed lots of sideplay.
After some searching I understand you can replace the bearings but my question is what bearings do I need to buy and where the best place to buy them from is? CRC have 3 options listed (all very expensive) but no description to what the differences are etc 😕
I also understand I need a special tool to remove the inner bearing, is this fact or can I bodge it out with something that doesn't cost the same as a weekend away with the family 🙁
TIA,
Jeff
No you do need to remove the star ratchet ring thingy, for which you need the DT tool, take it to your LBS, it'll be much cheaper in the long run.
I forget what bearings they are, but you don't need to buy the stock DT ones.
You can get the bearings off eBay. I think the DT Swiss site lists the dimensions rather than the bearing code but you can work backwards from those to work out the corrent numbers - the betd.co.uk web site lists codes and dimensions and you can buy from there, or Hope bearings of the right side, or off eBay - there's a fella there in Manchester who sells SKF - or from a bearing factor locally. 6902RS rings a bell, but don't quote me on it...
The tool thing is more of an issue. They used to cost about half that, I think, which is why I have one. I've used it three times now, which I figure has paid for itself over LBS labour charges. Also, the DT Swiss lube is very thin, don't use grease or the freehub willl drag, also careful getting the labyrinth seal properly seated and the right way round. Otherwise it's quite straightforward really.
For future ref to anyone else with the same question the SKF bearing part number is 61902-2RZ / C3VT105 or the IJK part number is 6902RS.
LBS helped me out with a tool, charged me 20 quid labour and they stripped the hub down and fitted the new bearings.
Update, you can also go for the 61902-RS1 bearings which have 2 rubber seals instead of plastic seals, better protection from dirt and water but do run slightly more friction, but not that you'll really feel it on an MTB.
I did mine a few year back and used cheapo ebay bearings. They did drag a bit though. Go for some stanless steel bearings or ceramic even. If you are going to buy the tool to remove the outer star drive then I would go for cheaper bearings, as you will be replacing them yourself. If having a bike shop to fit them it would be better getting higher quality stainless steel bearings or the cearmic ones. Mainly due to keep paying out at the shop for it doing, it will work out cheaper.
I found not many LBS up my way wanted to do the bearings as they did not have the tools or know how etc. Simple enough job though.
