Just undo the three screws on the cover and the motor will pull away. The rear bush is right there. The front is accessible from the armature side. I did not pull the fan off as it is more than likely to break. Squirty lube with a nozzle tube is best. I used wd40 then motorcycle chain lube.....as I tend to use that on most things!

I then stuck it straight across a battery to make sure it was fine as now you are aware they are not fun to get out and in.   

Quite so, came apart easily. Pics follow

......
. They are clearly designed to run for the life of the car without trouble.

That's probably because they appear to start with the interior fan assembly & build the entire car around it

I used my grandson's flexible drinking straw to pour oil into the rear motor bearing; I could oil the fan end bearing with the straight straw. Pics show lubrication of rear bearing, and testing. It ran very quietly, but so did the one I removed after lubrication.


Now all I have to do is put it back together again.

Happys days, not too hard is it? And its free. 

A man after my own heart......battery and jumps leads, just how I did mine.   

Now you have two smooth and quite fans.

And motor held in a vice. When I changed a fan motor in 2006 I tested it on the bench; motor burst into life, leapt off the bench, scuttled under the car and disappeared. Amazingly it suffered no damage, and is still working 11 years later.

Thanks for your advice. Motor did not look serviceable, and I am sure was not intended to be.

I'm impressed Terry that you can see the top of your work bench. Mine is a little more cluttered ....

.. and a microwave for pies =  no need to enter the house.

(I'm assuming there's also a supply of beer, of course.)

A mysterious 5 pin socket has appeared below the wiring harness under the heater fan. Hopefully it is a spare that need not concern me. Can anyone identify it?

Is that a sticking plaster on your hand. I think they are an essential spare for working on omegas

Yes, there are three on my left hand and one on my right. Swopping heater fans is rough work!

At least there isn't any safetywire on an Omega. That makes nice neat 0.032" holes, or ragged tears that both bleed copiously.

Looks like the phone wiring as best as I can tell.

No not phone prewiring, I've seen that plug before but can't remember what it was for now!

There is phone wiring in the radio, with place for my SIM card and half the rdio handbook concerns the telephone.

Job is done, thanks to all for advice.
For some reason there was not enough of a gap to insert a T20 socket into the top right fan screw. I ground a couple down, but they still wouldn't go in straight. I tried a bent T20 allen key, but that was hard to get in straight, and I finally managed it with a bent T15 allen key, a loose fit but went in easily and had plenty of grip to turn the screw. Pic follow of my tools for this job.
