Crankcase cover starter clutch bearings
« on: 08 April 2018, 05:28:31 pm »
Hi all


Recently I unfortunately came off my bike and damaged the crankcase cover (not enough to not be able to ride the bike) so I brought a new crankcase cover however it didn't come with the bearings (Attached photo highlights where the bearing is supposed to be in the crankcase cover) I can't take the current crankcase cover off and get the old bearing out as it isn't possible without further damaging the cover, nor can I just go to a bearing shop and ask them to make the bearings as I do not know the measurements.


Does anyone know where I can get hold of this bearing for the crankcase cover? or does anyone know the measurements or what I would have to tell a bearing shop to make?


The bike is going in for repair soon so I really need to hurry up and get hold of this part.


Thanks in advance

You can use a blowtorch. Turn the old one with the bearing in so that when the bearing falls out it will fall to the floor. Heat up the bearing and the area around it evenly until it just drops out. Place the bearing into the new cover and heat the surrounding area until it drops / requires little force to push it into place. This works due to the metals expanding at different rates

Obviously take necessary precautions, it’ll be hot.

Thanks for the idea but I've already seen someone attempt this, the risk of either breaking the case and/or the bearing is just too high, the crankcase cover is still fixable but I now want a second set of bearings to put inside the new crankcase cover.

Bearing shops dont make them on a case by case need and the chances are it will be a common size - once the cover is pulled off you should be able to see the numbers and grab one at any good bearing supplier - otherwise it is scour through fowlers to find a oem part number and pay over the odds


i will admit that i am lucky to have swan bearings nearby and they have only failed me once - but this was on a very obscure size made BY THE BLOODY FRENCH (Peugeot)

your laughing a 6200 should be 10x30x9mm
if your local bearing supplier doesnt have it and cant get it within 24hrs get a new bearing suplier
if you get a 6200-2rsh it will have an oil seal on both sides which keeps the grease in - if it is in a live oil area this shouldnt matter but i would go 2rsh

i couldnt be arsed looking through cmnsl or fowlers but it shows it as being an open bearing so if they have them, go open bearing
but as said - its a common size number (so common i think i actually have some 20yr old ones in my trays lol)

What is all this 6200 bearing talk? The 4 digits inside the new crankcase cover say 2663. Can someone please explain all this to me in layman terms please because at the moment I really need this bearing and it looks like I'll have to go to a place that makes them but currently I have no idea what it is I am asking for

6200 is a code for a specific bearing - a ball bearing bearing
if the stamped code is for the bearing then a 2663 would be be a roller bearing
just ask your local supplier for a 6200 open bearing and you should be fine
(just put it in your freezer before fitting as it shrinks it)

So any 6200 10x30x9 bearing will do? Only reason I'm asking is because you can buy 6200 10x30x9 bearings on amazon and ebay for 99p

go for a decent make like skefco (SKF Bearings of Luton) or some other branded one, lots of unknown bearings on eBay that I would never use.
if a bearing is not within tolerance it can mess up an axle or drive shaft or mess the bearing mounting in a case of wheel or where-ever.


Find out if the bearing runs in an oil bath within the case, if it does go for an open bearing, if not then a sealed bearing.

best going with a known supplier - SKF is one of the more well known suppliers for a reason
it may be 1-2 quid more that some ebay unknown but you know you are getting the precision with true skf
(€pretty much as tommy says - we are in agreement on this one)

This is great thank you but I don't know what options to select? I literally have no idea about this sort of stuff, thank you for finding the link but could you please tell me what options to select on all 3 drop menus?

If you you cannot get 6200 CN  version get the 6200 C3 version. They may be the more common version of  the 6200.

Thank you so much guys for all the helpful information, I apologise that I needed everything spoon feed to me, all these little bits and bobs of the bike really ain't my strong point, I was originally looking at the yamaha part number for the item and was gonna spend £16-£18 on this bearing, thanks for all your help again.
