Have just replaced main bearing on my cr01 memory even though dyson cannot. I purchased a 633007c wheel bearing from ebay for £50 there seem to be many available.They are 2mm short in the length 34mm rather than 36mm standard but a 2mm spacer is easily made to make up the difference. The machine is quite easily dismantled although I had to weld up a special spanner to undo the large nut at the back of the drum. With the front of the drum off the drum was removed. With some 20mm threaded rod and some scrap steel i made a puller to pull out old bearing. It was very tight in the housing but by putting pressure on it with the pull and hitting hard from behind it eventually moved. I used the same threaded rod to pull new bearing into place and then fitted spacer then circlip. A seal was purchased from local engineering supplies for £5.00 and is easily tapped into place. The drum was the refitted using the threaded hole at the end of the drum shaft and some spacers, to pull it through new bearing. Everything back together and it runs a dream.

Hi Richard. Welcome to the site. :tiphat:
Thanks for sharing that. It will be of great use to others. :icon_nod:

Hello,
Thank you for your advice its the best info I've seen on these machines so far.
I my CR01, the drums have become seized together (which I think is a common issue).
I think I can fix it, but an having a great deal of problems getting to them.
I am finding it very hard to undo the large 4 slotted locking nut on the back of the washing machine. In your reply you made a tool, I have tried to make such a tool out of a piece of exhaust tubing, but it is too soft a metal. Can you advise me how you made this tool (and any pictures if possible) as I'm at a bit of a loss how to undo it at the moment.
Thanks,

Hi, I have photos but cannot up load to site. I could email them to you if you pass on your address. I had a piece of 80mm pipe with about 5mm wall thickness. I cut off about 50mm and welded another piece of scrap on the back for a handle(about 500mm log). I welded some lugs inside the pipe 90 degrees apart and ground them into shape. Holding the centre of the spanner on the nut with my knee a couple of hits on the handle with a large hammer and it loosened up. It is very stiff because it has nylon insert, like a nylok nut.
Hope this helps
Richard

A little gentle heat on the nut might help start it moving. You could put back on with some threadlock if nylon in nut has melted

Hello, and thank you for your reply,
My email address is *snip*
If you could send me a few images it would help me in trying to make such a tool myself, but while I can saw and file pretty well I have no access or knowledge of welding -myself.
I know its a bit cheeky, but alternatively, if you live near Southampton, would it be possible to borrow the item maybe?
I gladly pay you for the trouble and return it immediately.
Dan.

Hi, I have photos but cannot up load to site.
Further to your PM, I'll do a quick "how to" on that if you still have problems.
Dan, I just removed your email address from the public post. You can PM it him no worries, but we are crawled so heavily by various robots that if I left it public you would have an inbox full of all kinds of crap within days.

Hi, you can borrow the spanner no problem, but I live in Norfolk. Do you want me to find out the postage.
-
Hello,
Thank you for your help, Richard (and the moderator too).
I've sent another message via 'PM', as email address are not allowed in normal postings (which when thinking about, it is probably a wise thing).
Thank you once again, for you prompt help :-)
Daniel.

I've done that now, it can be found >>here<< (https://manchestervacs.co.uk/DysonForum/index.php/topic,506.0.html)
Any photos or other info you guys could supply on these would be a most welcome addition to the forum. :icon_nod:

Just finished, sorting my machine thanks to the above wise man and his assistance!
And now it works perfectly and does wash clothes to a higher standard than my old Miele, or any other machine I've had for that matter.
It takes quite a bit of effort to dismantle and that big slotted nut on the back is a pig to remove (had to borrow a tool from a Dyson wise man to undo it). But once that's done, pretty smooth sailing, only those torx bolts around the edge are a pain, lots of nut release, leave for 15 mins and then TIGHTEN not loosen one at a time. This gives you a bit of leeway to then start to undo them, I managed to undo all of mine in the end.
The casing is then also stuck to the spider and reassess, but with more release spray and lots of flat screw drivers, it is possible to get the spider and the inner drum out. Note you do not need to remove the 3 torx bolts that hold the spider to the inner drum. Then just de-scale everything, clean the yellow slipping ring and put it back together.
Also note, the bearing is massively over engineered and isn’t necessarily the cause of the drum seizing, just lime-scale build-up in the slip joint and inner and outer spiders, if your bearing seal is ok, then the bearing will also be ok (in my humble opinion). They do move a bit with the drum removed -but this is normal, they rely on pressure on both sides to keep then straight. So maybe then just huge de-scaling wash, maybe all you need to fix these machines in future.

That's great info Daniel and Richard. Thanks!
Judging by some of the emails we get, your contributions will be most useful to others. :icon_nod:

Thank you,
It would not have been possible without the communication on this site and he tool created by one of your members here and his generosity in allowing me to borrow it.
Thanks.
Daniel.

This is a great site ..Many thanks to Manchester Vacs for running it... seems that DYSON have lost out withdrawing their support?

Hi, part way through a bearing replacement, following the excellent guide on the site. However, the drum securing nut is a problem, a few large hits with a club hammer and bolster have resulted in nothing but damage to the nut. I know Richard has manufactured a tool to remove it, but he hasn't been on the site for a while. Is there another way of removing it using an adapted tool or if anyone can loan me a suitable tool. Many thanks.
-
Send him a PM after you have three posts and see if he will loan it to you?
-
OK. One to go.
-
And there it is. Thanks.
