This is the info from the KOYO website for 6028 2rs bearings, they seem to be saying that they are 33mm wide and 210mm o/s

Bearing No. 60282RS
Boundary dimensions(mm)
d 140
D 210
B 33

r(min) 2
Basic load ratings(kN) Cr 110
C0r 109

Mounting dimensions(mm) da(min) 149
da(max) 158.5

6028 is a different beast to to what I said it was which is a 60/28

Measure the bearing and buy SKF.

I'm sure you'll find a local dealer on their webpage.


Not all bearings are available from the local bearing factor or manufacturer, which what this thread revolves around

the manufacturers use 'specials' to force you to but them from them at highly inflated prices

Update,
Went and got one from the stealers the other day for a grand total of 17.
Went to the local bearing suppliers( Anti friction components( Wales)) today to get it matched.
Reply was "Yes sir, no problem, we always carry about 50 in stock because it's a common bearing and we sell loads of them".
Total cost was 9.30 inc VAT.
The only difference was that the inner ring that the wheel spindle goes through is slightly thicker than the OEM one( was gonna take a picture but forgot), I asked the counter guy about it but he said that because it is the same bearing in every other aspect(inc pat number) that it has the same load rating and specification as the original.
Anyway, all that said, I changed both bearings but only one of them actualy need doing, the other one is still like new.
So if anyone out there who does'nt do as many miles as me(30000 a year) finds they are in need of a rear wheel bearing, then I've got one you can have that should be good for at least 10000 miles.
Just let me know and I'll drop it in the post.

So how many miles have you racked up on your trusty 900, CB? Was thinking the figure could be quite impressive by now, depending on how long it's belonged to your itinerant self, of course! wink.gif

30,000 miles a year! Good grief... (Even at 30,000 km a year that is impressive)

Seeing as bearings seem to be a lot cheaper from our local bearing dealers,as well as being more readily available("i can get that for you next week sir")would it not be a good idea to store all this infomation in the knowledge base.Then as peeps change bearings,they can add to the list and eventually we would have all the sizes in one place as a source of reference.

After finding the rear wheel bearing codes here on Carpe, then having success replacing them after purchasing a heat gun, I decided I'll grab some fronts and replace them so they're all done at the same time. Didn't really need new ones but I haven't owned it since new, so now I'll know the history. Check here on Carpe, this thread says the front bearing is a 6004, drop in to my local bearing place on the way home from work yesterday, pick up two 6004's (AU$8.50 each! Too easy.).

Only just got around to putting them in, so remove wheel, heat hub, tap bearings out (so easy with some heat), clean up hub, go get bearings from freezer, double check they are the same size....... blink.gif

The front wheel bearings in my 2002 TDM are 60/22s, not 6004. The 6004 is miles too small both OD and ID.

So now I'm stuck here on a weekend, both bearing shop and bike shops are closed until Monday, bike sitting outside with no front wheel bearings sad.gif

The only consolation is that the weather is really crappy - if it have been a fine sunny day it would have been much worse.

Was the original thread wrong, or could my bike have had the hubs machined out and larger bearings installed for some reason? Would like to clarify for future readers of the thread...

edit: The axle wouldn't fit through the 6004 in any case and that would seem to be standard.

edit again: can't find a part number on the wheel but it does have 5PS cast on it. Not sure why anyone would have changed an 18 for another 18 from a different bike, but it was worth checking.

Also checked my parts catalogue - it lists the front wheel bearing as 93306-00428 Bearing (B6004) which suggests it should be a 6004, however the same catalogue also says my bike should have a 13 tooth front sprocket on it......

Last edit, I promise... Here is a link to the NSK ball bearing range, with dimensions, part numbers etc

Assuming you have the 2002 TDM900 then from what I can see the same bearing is used throughout the years.

Looking at the size charts for a 6004 the bore is 20mm and the outside diameter is 42mm however if you select a 6204 the bore remains 20mm and the O/D 47mm. is it just a case of measuring the bore and O/D and selecting the appropriate series bearing.

Thanks guys, but I know what bearing I need - it's a 60/22, which is 22mm inner, 44mm outer. The code is written on the bearings I took out, and the size charts match with my vernier caliper measurements. I have absolutely no doubt what I need to buy on Monday.

My concern is this thread originally specified that the 2002 900 took a 6004 front bearing. The generic 6004 bearing is 20mm inner/42mm outer (from size charts and my vernier) and it certainly does not fit my bike. What I want to know is what bearing do others have in their bikes? Is mine standard (I expect it is)?

I suspect the Yamaha part code is 6004 (as shown in the link Studley put up, and in my parts catalogue), and by an awkward coincidence this is also the generic code for the bearing I got from my bearings supplier.

I just want to confirm what is the right generic bearing code (I think it will be 60/22) so that others looking for this info will be able to get the right bearing....

Ok, fitted the 60/22 front wheel bearings, they were supposed to be $13.50 each, but he couldn't be bothered with the paperwork so did a straight swap for the 6004's I bought last week (at $8.50 each). Been for a ride and no wheels fell off so all good...

I'm going to summarise the info here for anyone else who wants to change them without paying for Yamaha OEM parts.

Generic wheel bearing codes for 2002 TDM900 (and later models AFAIK)

Rear wheel bearing 60/28
Sprocket carrier bearing 6206
Front wheel bearing 60/22

Cheers
