Disassembling an AZ EQ6 GT?

[Jonk]

No, that's a steel washer stuck to the roller bearings. The last picture is the empty casting.

That was my thought - is there supposed to be 1 either side of the bearings, as that would make sense?

[mikeobrien]

Just stripped mine down and there is one either side of the bearing but it may be stuck to the casing inside with grease. I am photographing it all to show you mine. You have checked that the finer clutch plate doesn't have grease on it haven't you!

[Jonk]

Yes, I've cleaned and dried it 2 or 3 times.

I wonder if I've put 3 washers in the RA axis, or 1 washer was missing? The mount is 2nd hand, not new.

Thanks for doing some photos, I hope they help.

[Jonk]

Right - as I guessed, I had 3 washers on the RA axis - I can only assume one was stuck and when I reassembled it, I didn't notice, therefore having 2 on 1 side of the rollers.

I wrongly assumed they were spacers used when tested in the factory (like shims). Obviously not!

Moral of the story - check twice!

It's back together now and appears to be fine (offload), so tonight if it's clear and not too windy. I'll set up outside and test with weight on.

For others wanting a photo guide, I haven't got photos of every stage, but now know how it all works.

it really is straight forwards, probably easier than the HEQ5, so am happy to help where needed.

[mikeobrien]

So was the missing washer from the Dec axis the one closest to the mount casting.

[Jonk]

I tried it both ways with the same result. (i.e. washer brass side and casting side of the rollers).

All 4 roller bearings (2 large, 2 small) have a washer either side.

[mikeobrien]

Yes that's right I recon the steel washers are smoother and more hard wearing then the material the casing is cast from.

Hi!

What are the references of the bearings ?

It seems there is a NK 40/20 TN needle bearing, a ball gearing (40 mm ID) and a thrust gearing (AXK type, but what diameters ?).

I need these figures to calculate the periodic terms of the AZEQ6 mount for PecPREP.

Hello again!

I was waiting to do more measurements of guiding performance after cleaning and regreasing only RA axis.

Buuuut, now I have problems with my ASI120MM (my guide camera), so I think it is better you make your own opinion:

I'm really happy with the results!

Thanks Mike

I have not started this yet.

What do i do to get to the bearings in the RA axis...there are 3 grub screws to come out before loosening a nut?

[mikeobrien]

Yes there are make sure they are fully loosened so you don't damage the thread when undoing the black collar. You will then be able to pull the Ra axis out and remove the ball bearings and thrust bearings, just make sure you lay the parts out in the order that you extract them.

Ok...Mike

And the dec axis?

[mikeobrien]

Have you managed to undo the RA and dissemble it?

I am working my way up to it.

Before i do this please tell me how i remove the counterweight shaft from the mount body...i need to get this out for a problem i have with the mount for the secondary saddle whose bolt that you tighten down onto the cw shaft has sheared and i need to somehow drill it out...the cw shaft seems to be trapped somehow in the body of the mount

[Dr_Ju_ju]

An earlier question was posed on where you can get additional power connectors, after much searching I've managed to find these http://www.ebay.co.uk/itm/2Pcs-Wire-Panel-Connector-GX12-2-Pin-Male-M12-Circular-Aviation-Plug-Connector-/381337396899?hash=item58c97ae6a3, which unfortunately come from China, although I believe there is an Italian supplier as well.... 

If only Synta had used the more common GX16 series, which are available almost anywhere....

Seems like the cw shaft can only be removed out from the primary scope side of the mount (i'm in alt az mode only with this mount)..and to do this i need to remove the second scope saddle holder from the shaft which i cannot as the one bolt that secures it to the cw shaft has jammed and the top of the bolt has sheared off

Help

[mikeobrien]

The counterweight shaft does have to come out that way, get a screw extractor to try first before drilling it out.

Screw extractor didn't work unfortunately

[mikeobrien]

That's a pity can you male a slot in the head to get a slotted screwdriver in. I take it you have sprayed it with wd40 and given it time to work its way in.

[mikeobrien]
