I recently bought a CM 1.8m - it came with what i think is the original CM polarmount for 1.8m.

Its pretty rusty - so i'd like to give it a refurb - or at least check that its going to work nicely.

What are the key components to check \ maintain \ how can i check its all working properly without putting it all together (dish etc) - as i only really want to do that once dish is painted and the concrete base is down as its a heavy old thing.

I've read about bearings, but unsure what \ where they are \ how to check \ fix them up.

Here is a pic of what i bought.

Thanks all.

I think just clean the metal, repaint it or better have it zinc coated. Change all nuts&bolts to INOX, however galvanized are also OK. And you are good to go.

Advice Needed - cm polarmount ?.

Indeed you are correct @ozumo it is a steel insert /bush in the photo ... so long since i had one apart and took that photo , i had forgotten that ... the 1.8 is almost certainly the same i,m sure .. i will see if i can check that later without removing the bottom bolt , as the mount is in...

Those are only consumables... the main thing is the fact you've got a nice, original CM polar-mount. It is not rare as chicken teeth, but seldom and valuable enough. Just be happy about that fact!

If you want to have a real top spec job, you could take it to a local workshop and get them to sand blast it back to bare metal then get it powder coated or galvanised.

Alternatively, a small local car body shop would be able to do a real good job of back to bare metal followed by a spray with 2K primer then a top coat.
If you take whatever non metallic paint colour they have to hand for current car panel repairs then it might reduce the paint cost. They will have 2K primer by the gallon.

I think the "bearings" are oilite bushes rather than traditional bearings that have ball race enclosures. I could be wrong on that point though?
If they are oilite bushes then just a lining of machine oil should be OK.
