Removing the cutterhead onan elu thicknesser jointer to replace the bearings?
It is a long time since I encountered the Elu brand. I had to junk some Elu stuff 30 years ago due to inability to obtain spares. At least bearings are mostly standard items that can be sourced from many suppliers.
I haven't replaced bearings on an Elu jointer but the design and construction is probably similar to other brands so the process is largely intuitive using the usual techniques - warming plastics, aluminium housings and using bearing pullers when appropriate.
If all else fails keep removing bits until the part you need is what remains. Often that is the only method that works due to such tools being designed to be assembled in the least possible time and least possible number of operations. Sometimes the construction is downright sneaky...
It doesn't matter if the original bearings get knocked about or stressed by the removal process but ensure the new bearings are treated gently and not stressed by pressing only on the inner race to fit on a shaft, the outer race to fit into a housing or alternatively warming a housing will ease assembly.
