Timberwolf Fins and flywheel bearings

Or carefully Dremel them off if they've become welded to the shaft.

 

Cut them carefully and use a flat screwdriver to open it enough to slide of the shaft.

Something we have recently started doing, if the inner race is stuck on the shaft is to use a flapper sanding disc on the grinder to grind down the race. It is easy to spot the moment the race goes wafer thin without marking the shaft. Then just tap it off. Much less risk than using a cutting disk to slit through the race

I'd never advocate using a full sized cutting disc on a grinder, the Dremel is almost surgical with a 1" cutting disc.

 

It's almost like writing with a fountain pen if you have the flexible shaft version.

I've worked on a lot of old machines in the passed, and found bearings stuck on managed to get them off in the end. Have cut them at 12 3 6 9 o'clock not right though a hammered them to brake, welder is another tool I have used to get heat just on bearing.

Its certainly important to have a few tricks up your sleeve!

So have got it apart do I need to put anything on aluminium fins were they bolt to steel.

Gas axe is my go to for bearings on shafts, takes seconds.

Assuming you use a blue flame on your gas axe.

The bearings were easy to get off, it was the key in keyway that didn’t want to play ball. Had to weld lump of steel to it get it out.
