Hi Guys

It is possible to change the Main flanged Primary shaft bearing and small needle roller bearing?

Hi Guys
Can anyone answer this? I know I can pull the bearings off but I'm struggling to find a replacement as the numbers on the main roller bearing does not match up with anything. I don't want to pull the bearing off and housing in case I damage it before I know I can get a replacement. I pretty sure the bearings are fine but would like to replace them anyway to be sure.

The main bearing in the clutch side housing is available from Honda - needle bearing is not. The main bearing does go bad, I've changed 2 of them.

Martin,

I know someone who I think may have the needle bearing (part 91024-422-000), let me know if you want me to check it out.

Hi Dave, Thanks for the information, thought they were unobtainable, fantastic.

Paul, I'll get back to you on that once I've pulled main bearing off after my hols.

I don't think there is anything wrong with the main bearing, its smooth, I cant detect any play, however when it gets hot it may be a different story. I'm going to replace everything I can this rebuild.
