2strokeTom Posted March 10, 2022 Share Posted March 10, 2022 Hi after some help with a transmission bearing please. Im rebuilding my yz125 2003 and need to replace one of the transmission bearings. The bearings is an ntn 6304x3nx2. It has a snap ring on the outer race. Is this just a normal 6304 bearing with snap ring or is it a specific bearing made for yamaha? As I am having trouble locating one without going to yamaha direct and paying the privilege. Thank you in advance, Tom Link to comment Share on other sites More sharing options...

2strokeTom Posted March 11, 2022 Author Share Posted March 11, 2022 Thanks for the replies. Yes I have no problem finding a 6304 with snap ring but don't know if it should be standard clearance or c3 clearance. Link to comment Share on other sites More sharing options...
neversaydie Posted March 13, 2022 Share Posted March 13, 2022 Look closely at the old bearing. Sometimes the clearance is marked onto the races, e.g. C1/C2/C3, and someitmes the clearance is indicated by a number of circular marks like this OOO (C3)> I fyou cant idnetify it, then just bite the bullet and buy genuine, that way there is no doubt. The cost is negligible over the lifetime of the bearing. Link to comment Share on other sites More sharing options...
