Hi All
It looks like the bearing is a standard open 6300 bearing. Is it standard or C3 clearance??? Anyone got a new one to check?
Cheers

I just got a replacement pattern one from Norbo.
I’ll dig it out of the box and put a pic up later if it will help.

Here you go. I think the genuine one has a plastic cage but here is a pic of the old one I have taken out (left) and the new from Norbo one I am going to fit (right)  New one on its own  |

its just a standard bearing, doesn't need C3 clearances as its running in oil and not heavily loaded, still available from Yamaha etc and also most bearing stockists as its a standard NTN/Koyo bearing

Thanks. That gasket does not look very good. The ones I make are a perfect fit. The part that sticks out should have a parallel slot in it, not tapered. This is one of mine :-  I would not trust his bearings either, as may be a cheap Chinese one and is sealed, when it should be open so it gets lubricated by the oil in your gearbox. |

Most of the time the waterpump gaskets in the kits are a terrible fit. You should defo advertise some of yours in the sales section Rob, if i'd known you have them Id have bought a bunch a while back :/

As Dave said it runs in oil, so why would you want a shielded bearing? Jon |

Your correct , the gasket wasnt a brilliant but its sealed well enough when you look at the cost of the seal and bearing Vs Yam, its good value. No issues with the bearing n seal in a couple of years since its been installed... |

An SKF 6300 is just over a lady. Jon |

If never used to be a std bearing, it used to be made from rust proof metal and not a std clearance.
But Yamaha have a habit of changing things

Jon No....never even noticed it Jon, im a simple guy, a bearing is, sorry, was a bearing, if it fitted it went in...nearly every day is a school day with these things..I'm not worried eitherway. ...ill let you know when bearing stops doing the bearing thing...at 250-500 miles a year, i expect it'll need that cover off for something else before hand. |
