Vicon Fanex 553 tedder bearing

[Jim88]

I need to replace a bearing on a Vicon Fanex 553 tedder and just wondered if anyone knew the best way of going about it?
The bearing is the one just above the UJ in the picture. It doesn't look like it is possible to remove the UJ yoke from the drive shaft.
Is it possible to pull the shaft out of the end rotor and then out through the bearing ?

Split the tedder at that pivot, just withdraw the two pins. You may have to drop a rotor as it depends on rotation which side of the crown wheel the little pinion gear is to get it apart enough. Usually there’s a pin or something through the yoke to shaft

Thanks for the advice. It looks like the pinion gear is mounted in the same gearbox as the rotor.
It might be possible to drop the gearbox a few centimeters and see if there is a circlip on the end of the hexagonal shaft? Its a shame there is no access from the end of the box section arm.
Sorry the picture is not very good quality but hopefully you can see what I mean about the pinion gear.
