Default Router Reassembly

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

I DON'T HAVE MUCH INFORMATION, SO I am going to tell You, Take to Your selling store. Explain what is happening. What policy dues the router maker have in affect? You can tell them that You are on an international forum, and You would like to have some good news to reply with! Work with the factory if You have, or can get the number! I see that You are putting it back together! The factory may still be able to help You. They may be able to diagnose the problem.

There's a toolshop on ebay selling armature kits and bearings for the DW625 for 49. You could try asking it for detailed reassembly instructions. Or go to a Dewalt specialist, I am sure there must be many. I would say that after reassembly you should be able to spin the collet without any resistance at all, by hand. If there is resistance, you've over-tightened or over-compressed something. Also heat at the collet does not indicate the source of the heat, as heat travels quickly in metal.
