My bearings have gone on my Dyson CR01 washing machine and I've completely dismantled the machine and have removed the (one) bearing and seal. This would now be an easy fix to reassemble, but I can't get hold of a new bearing or seal - they are a strange size and bearing stockists are all coming back to me as unable to obtain. Does anyone know where to get a bearing that is 50x90x36? Cheers, Alan

I have managed to change all the bearings successfully. Search on facebook for the Dyson CR01 group and you will be able to download full "how to fix" instructions including what parts to buy.

Hi,

I realise that this thread is quite old, but I was wondering if anyone has perfected the bearing replacement for these machines. I have a CR01 whose bearings aren't in terrible condition, but will need replacing at some point as I suspect that there has been water ingress.

Can anyone here provide me with some directions as to which bearings and seals to use as a replacement, how to extract the old bearing and any particular fitting instructions for the new one(s)? I currently have the tub and drums separated, so all I'd need to do is the actual bearing replacement itself.

As a sidenote, I only have access to an average collection of tools, so I can't machine or weld anything. I have mostly spanners etc.

Many thanks in advance,

easkay

Reading this thread, i'm now feeling even less confident about changing the bearings on my CR01.

I did buy a spare washer a few years back - to use as spares, as i had a feeling this may come in hand.

Would it be easier for me to just exchange the drum units?
Any advice on this would be really welcome.

Hi Daniel, I had a tool made, but it didn't shift the nut - I just couldn't get enough torque on the tool to shift it. In the end I went back to gently heating the nut and used a hammer and bolster to knock it round. It eventually moved, but it's on tight and probably with some lock compound too. When I re-assembled, I used some lock tight and the hammer and bolster again and all is still well after a year. Good luck, Alan

Hello,
I'm in the same boat as the last chap, how did you make the tool the remove the 4 slotted locking nut on the rear? I tried to make it out of an exhaust tube but it was too soft. If someone would be will to allow me to borrow theirs, I would be very grateful and pay for the postage there and back plus more for your trouble :-)

Have just completed main bearing replacement on my dc01. Used 633007c bearing (Ebay £50 a formula 3 wheel bearing) Oil seal available from local engineering supplies for £5. The large nut was removed easily using spanner i welded up out of a piece of 80mm dia pipe and some scrap. With the drum removed the bearing was pulled out using a tool made from some 20mm threaded rod and some more scrap steel, it was a slow process, pressure screwed on the rod and some hammering from behind and eventually it started to move. The new bearing was pulled in using the same jig in reverse and new oil seal tapped in. The drum was replaced in new bearing by pulling it through using threaded hole in the end of the shaft and bolt with some spacers. The 633007c bearing is 2mm shorter than original so spacer is required 2mm x 80mm with a 50mm hole in the middle. Put spacer in then circlip. New bearing was a little stiff at first but ok after a trial spin, very quiet now!!

How about 2x 6011 bearings (90x55x18) with a cylindrical bush inserted to reduce the bore down to 50mm such as Ondrives Ltd DP4 CYLINDRICAL BUSHES part number DP4-5040

BF, December 2011

solution of bearing replacement comes from SKF bearing 6210,which has dimensions 50x90x20. bore 1 mm on each side, so losing 2 mm each bearing at the 2 bearings in total 4 mm. put one over the other and with POXIPOL between higher rates

can anybody tell me if the bearings on a dyson comes out through the tub or if it comes out through the back and if so is there any thing I should remove first or should I just press it out with my press.

many thanks, GERALD, August 2010

hi alan ,
could you tx me with regards to removing my dyson bearings, it would be magic if you could , 07888802220. many thanks

OK, so now my bearing is in, but I've reaslised there are some issues to overcome. Firstly, there is an outside sleave to the original bearing, which I tried to get my new bearing in with, but it moved and broke when I was tapping it back in, in the end I've done away with this and by putting the bearing in the freezer for four hours it then just pushes in with your fingers. This now means that the bearing is only supported either end of the bearing housing (hopefully will make more sense if you are looking at the actual parts) so it's critical that it doesn't move so you'll need a washer 89.5 x 80 x 2 or 2.4mm which is more snug to make up for the shortfall of depth of the bearing before you clamp it all together with the C ring at the back. I couldn't find a washer this size so I had it made at lasermaster 01209821902 for a few pounds. I've also realised that I'll need another washer 67 x 50 x 2mm (on order) to put on the shaft on the back so that the pulley doesn't catch on the outer drum (again it's all to do with this 2mm shortfall on the length of the bearing). As soon as I get this second washer I'll post another update, but in the meantime I've also noted that the seal will need to be inverted and turned round before being placed in the tub housing as Dyson have put an unusual brass sealing ring which will foul this if assembled correctly.

thanks for the update and info

Anyone reading this wanting to change the bearings please note that Nationwide bearings (although very helpful) couldn't in the end supply the correct bearing (I bought it and had to send it back). However, I think I've found a solution in a bearing size 50x90x34 (the Dyson bearing is 36mm deep) SKF633007C Italy M 352E is the reference. Upon searching the internet I called a very helpful man called Nick on 07903 474 191 and he supplied to me a pattern bearing (same size) at a very reasonable rate (the SKF one is again over £100). For the seal I've decided to use a 75x100x10 (as opposed to Phil's solution to get one 74x100x13) for clearance purposes. I bought this from Simply Bearings as a Vitron rubber oil seal. As of yet I haven't re-assembled my machine so I can't say that it's all going to work, but having seen what is out there to buy (as you can't get it from Dyson) this is as close as you're going to get it from what I can see. Best of luck to anyone trying!

Alan Batchelor, June 2010

Hi Phil, many thanks for your reply and the contact details of the bearing company, I have today taken a photo of the bearing and emailed them with the full details and now I'm waiting with baited breath to see what they say! Very interesting to hear how you got your bearing out, I have to say that I'm a little worried if I do manage to get a new bearing how I might get it back in... I'm told to put it in freezer and heat the housing. Sorry to note that you're going to get a new machine!!! I guess if it was my main machine then I'd be in trouble as the two I have have been in pieces now for months. Having two machines in pieces I do have most parts twice, however, I would be interested in the control panel if your machine still contrarotates? Of the two machines I have one has been upgraded by Dyson to remove this part of the cycle so that the drums don't turn in opposite directions, the other circuit board will make the machine contrarotate, but the pixels have gone on the display. Let me know what you're thinking about costwise (and postage to London), but probably I should wait until I hear back about the bearing. Cheers and speak soon, Alan

Hi Alan. Fogot to give you nationwide bearings Tel No 01302 330366. Hope they can help you

Hi Alan,

Thanks for getting back to me today (30th April). Maybe good news! I managed to remove the bearing by taking it to a local agricultural dealer and using a 100 tonne press (no heat). The bearing went 'bang' at 20 tonnes of pressure, without distorting the aluminium housing. I think I can source the seal at simplybearings.co.uk - go onto their website and then go to oil seals - 3 boxes appear at the top, drop the cursor down and click on '74'; go to next box on the right and put in '100'. The nearest seal available is 74 x 100 x 13. I'm sure a man of your calibre could whittle off 3mm off the rear edge to take it down to 10mm. The price of the seal is £7.99 + £1.50 pp.

The bearing could possibly be obtained from Nationwide Bearing Co Ltd. They cannot source it from the bearing size itself (50x90x36), so I gave them lettering and numbers off the dust seal of the bearing which are: DE1021LA and they told me that the bearing was available (only one supplyer in the UK) at a cost to them of £95 - they would then put their upmark on this price obviously. I would also ask them to ask the supplyer what the acctual size is befor they oder it for you.

when we had the Dyson engineer out last, for the noise of the bearing, wich was(three weeks ago) he said use it untill you can't stand the noise, but we won't be able to come back to it in the future for anthing else, bearing not avalable, I should condem it.

We have now decided to put our money towards a new machine instead of pursuing this any further and so will be selling our Dyson CR01 for parts - everything is in good working order apart from the bearing! I was so looking forward to putting it all back together & getting it going again. Enjoyed stipping it down..

Wishing you the best of luck, would love to hear how you get on . . . .
p.s. Do you need any spare parts?

Phil

Phil Stead, April 2010

Hi Phil, I've contacted over ten main bearing suppliers/manufactures, done searches on the size of bearing on the internet and even taken the drum assembly into a bearing shop and everyone cannot source it (nor the seal). I have been waiting for GH to come back to me now for two weeks, but am coming to the conclusion that I may have to modify my machine to have two bearings with a depth of 40mm (instead of the 36mm). This will affect the alignment of the gears though, so that's another problem. There is another discussion forum where someone has already done this and has noted this and overcome this issue. If you have a machine that no longer contrarotates then I guess this wouldn't be too much of an issue. If you have removed all the gearing and are just left with the back plate on the shaft held on with one large castle nut, then the way that I got this off was with heat (with a steam generator iron) and a hammer and bolster - it's almost an impossible task though, it didn't move for days and I would come back to it and try again and again. I built a tool with leverage handle of four foot and that didn't budge it either! I'm afraid to say that's only the start of it though as the (one) bearing is even harder to remove, I tried pulling it with bearing removers, but again heat from the iron and hammering are the only real ways. When the bearing is out you will see that the bearing is only supported at either end of the bearing housing which creates another issue that you can't have a shorted bearing. I'm a bit of a washing machine fan so I'm now doing this for a labour of love and actually have two machines lying apart in my cellar wondering what now to do with them, I will however probably try the two bearing option if GH doesn't come back within another week. Let me know if you need anymore help. Cheers, Alan

Alan Batchelor, April 2010

Hi Alan. Just seen your problem & I'm having the same trouble sourcing the bearing & seal here in E. Yorks.

Would love to hear back from GH & the bearing suppliers in Manchester. Q. how did you remove the outer race? Did you have a v.big hammer or use a hydraulic press?

I have found out today from my bearing supplier, that Dyson will probably have had the bearings & seals made to a spurious size so that only his company will be able to use them and therefore they will not be run of the mill bearings sizes (due to it being a patented design throughout).

Any feedback would be much appreciated.

PS. Do you think it would be possible to use 2 smaller separate bearings side by side? E.g. 2 x 18mm bearings as opposed to 1 36mm bearing.

Phil Stead, April 2010

Hi GH, many thanks for your reply, that would be excellent if you know someone. Cheers, Alan

Alan Batchelor, April 2010

Hi Alan,
Dyson don't provide them direct. I understand there's a place in Manchester stocks them but the name escapes me at the moment. When back from my business travels, I'll try to dig out the name for you. Regards, Graham
