Bearings won't fit Axle.

Great forum guys

So I replaced my CV's on the brumby.
New bearings too.

Bearing fit hub perfectly.
Axle won't fit through the bearings.

I've had multi mechanics and engineers tell me, "just put the hub in the oven" or " get some wet'n'dry on those CV's," or "No no no, you don;t need to machine press them on, they should just slip right in"

It's killing me, I need this baby on the road pronto...

Can someone in the know please tell me what's going on here ?

Much appreciated.

Are you able to measure the outside diameter of the axle and the inside of the bearing accurately. ?
Can you look at the old bearing and read the number off this bearing and compare it to the new bearing ?
Just thinking maybe the old and the new bearings may be different.
Wet and dry maybe if there are some marks, rust etc on the axle shaft.
As for put the bearing in the oven, this is usually a method used on larger bearings, I have never needed much more than a bit of extra effort with a copper dolly/punches/press/copper hammer to put an MY or an L series bearing on.

sometimes the cv shaft is afew microns thicker than the inside diameter of the bearing.

Ive had this before.

Wet and dry sandpaper on the cv shaft is the go.

they DONT need to be pressed or anything. It should slide strait in

Would be a bit more than a few microns but yea, just enough bigger that they dont' go in easily. +1 for wet and dry paper, just polish them up a bit until they go in, make sure to try and polish evenly all the way around.

I've been away so haven't had a chance to finish this as of yet.
Going to go grab some wet'n'dry in a bit and have at the axle.

Yes, both measure roughly 35mm,

They're the same.

Cheer for the responses, much appreciated.

I think what Alex means is that it will help them fit. You don't want them to easily slide in as that will create other issues, they need a snug fit. They're not like the EJ setup where the hub is fitted in the bearing - the drive shaft pushes straight in very easily!

Some effort and patience is required with the MY and L series shafts
