Next, remove the end cover bolts and gently tap the covers with a piece of hard wood, I use the small hammer handle, just enough to break the seal.
Then using a piece of wood over the end of the shaft for protection, give it a couple of taps and viola, it comes apart..
You can see how dirty it is inside and bits of insulation/dirt fall out. This is why I clean the shaft ends, as the bearings could be mounted in the end covers, or they could be a shrink fit onto the shaft.. So it’s better to have no obstructions, dirt, rust, high spots on the shaft as this will cause the bearing to seize.
