Doing swingarm bearings on a 2016 yz250x and the pivot shaft will not slide into the collars inside the bearings. I thought at first maybe I was sent the wrong parts but they sent another set and they don’t fit either. The bearings and everything installed into the swingarm with zero issues and fits as should but the pivot will not slide into the collars. After measuring the pivot shaft comes out to 17.86mm and the inside diameter of the collars are 17.13mm. Currently have no clue what do

Sure you have the swingarm and not the rear axle?

Are they flush? Too much grease?

I don’t believe either is the issue, I’ve pulled them out and tried sliding them onto the pivot shaft and they are just simply too small but I don’t understand why.

Possibly, but I contacted them and they sent another set out and according to the part number on the box it’s correct and this is the second set and they both are doing the same thing
