flexi grinder

[500e]

Now beloved is home from hospital again I can have a small fiddle.
So thought re build grinder handle/chuck assembly of My Wolf FF2C 1200/ 11500rpm flexi die grinder.
New burrs leapt about due to bearing wear, stripped both handles (1 spare) they require bearings, not a problem even though a 50s machine, then I thought seeing it is out of action a new mains lead, tick.
This is where I get carried away might as well strip step up gear box, undo the 4 screws all ok front plate of motor is the back of GB casing all slides off great no gasket or seals in box whatsoever, the 2 output shaft adapters screw onto front of alloy casing no seals to shafts or ever have been the 2 adapters have a half three quarter mm gap between them as well but no grease has ever come out of box.
It is a great old tool that owes me nothing but with new burrs
What grease would be recommended for this job, would think something with a bit of body but as you can see there are 4 bearings 3 in blind holes none with oil seals, all after cleaning feel perfect.
They are still made in India by Ralli Wolf

Design looks the same other than mine is floor standing

I use tungsten disulphide on things like this as it beats its self into the surface of the metal to give it a coating , or a good molly grease if you dont have any , same idea just not quite as slippery.

@tom2207 thanks for that suggestion (tungsten disulphide) the carrier grease needs to be something fairly stable rather than run as there are no seals on the box and it houses the front motor bearing so molly would tend to leak, cant replace the armature front bearing as it appears to be fitted to shaft extension before it is fixed to armature either braised (induction heated or shrink fit)
Does the TDs powder thicken the grease to any extent was looking for the sort of grease that grinder gear box use as any that escapes is flung into motor casing

Had another good look at armature the nose is threaded on between bearing and fan, RH thread does not show it in the break down
