O dear, O dear! I am so dissappointed that my Elu177e is now seriously OVERHEATING the collet end of the spindle after running for less than a minute.
I can only presume it's due to rotational slippage between the inner race of the bearing and the spindle which can't be 'interference' fit so housing/handles can be tapped off.
I've fully tightened the 'lock ring' which must be for the purpose of solidifying both together.
FULL tightness of course has pulled the spindle (armature shaft) a couple of mm towards the collet so the saucer washers under the other (tail end) bearing would be now fully compressed - is this too tight?
With the circular cover-plate for the lock ring removed, I can see the outer race rotating very slowly in it's housing. This cover has a projecting rib - the diameter of the outer race, which may (?) clamp it stationery when screwed back in place.
Fact is, though a one time Instrument Technician, without detailed reassembly instructions I'm, frankly, buggered!
Any help to dig me out of this would be much appreciated
