HEQ5Pro maintenance

Hi,
I'm trying to dismantle my HEQ5Pro so I can re-grease (or probably just grease) the bearings. Has anyone any good method to undo the black round retaining nut on the DEC axis - the nut just behind the dove-tail head. I am trying with long nosed pliers inserted in the opposing holes on the nut. I can't budge it!

I use a small punch that fits the holes, angle it against the wall of the hole in the direction I want it to go and tap it lightly with a small hammer. Be sure to use light taps and alternate between the two holes.

An alternative to a punch, if you don't have a suitable one, is the plain end of a drill bit that is a neat fit in the hole.

I had a suitable punch Raymo, but thanks for the thought. And yes, I got it apart - after quite a bit of tap-tap-tapping.
Many thanks Steffen and Raymo.

OK Guys,
Would you believe - next problem. The grub screws holding the counterweight collar. They're deep down and only the allen-key can reach. I reckon I'll twist the key into a spiral before any of those little !@#$%^s will move. Any thoughts please.

If you are afraid of breaking off an Allen key, either use a small adjustable spanner [shifter]on the key, at a 45 degree angle across
the 90 degree bend in the key, so the torque is only on a short section of the key, and it therefore won't twist, and possibly snap off, or get a short straight Allen key that clicks onto the square end of the appropriate ratchet type tool.

The grub screw is quite deep in the collar and I have to use the long leg of the key which is quite flexible as the key is only 2.5mm. As I try to turn it I can feel the twist in the key. I have also tried tapping the key while applying torque but to no avail. Methinks this unit was put together by a butcher of the non-meat variety.
I would have preferred to leave the unit alone except it is quite noisy and has started stalling while slewing. Hence the decision to work on it.

UPDATE: A drop of Penetrene, a sustained twist and bingo!
As suspected, very little grease on the cone bearing. Will continue on it tomorrow.

If the key is of reasonable quality, it is amazing how far you can twist them. If it is a neat fit in the screw just keep twisting. It will come with
a snap, and maybe make your finger sting a little. You can use a shifter on it, of course.

Raymo, perhaps you mis-interpreted my "Bingo" in my "UPDATE". It meant I managed to undo the blighters. Yes, I used a little shifter to rotate the key and just maintained a steady pressure until it moved. Thanks again though for your helpful advice.

I didn't misinterpret the update, I didn't see it, but I'm glad you got it undone.

Make sure you wash out the old gunk before regreasing. I usually use a spray called brake cleaner/degreaser or something like that. It foams and smells good

It leaves all parts completely free from dirt and grease without attacking paint or plastics.

For regreasing I use my trusty old Mobilgrease HP (aka XHP 222) which will not separate, run, harden, dry out or anything, but there are lots of other quality greases that work well.

Don't use a punch or the 'end of a drill please. get a 'C' spanner that fits from a tool supplier. If you use those you'll damage the holes in the nut and in time it will become useless.

That's easier said than done. Refer to this image from Astro Baby's website:

How do you get in there with a C-spanner?

Had to use the punch Simon as the nut was inaccessible to anything else including a C spanner. Its really a job for a specialist tool. I was very gentle and there is little obvious damage to the holes. Hopefully, I won't have to pull it apart again.
Steffen, I'm cleaning things in Shell X2 solvent which I have on hand and I have some BP Energrease L lithium based grease, which I think should do the job OK.

Thanks again for all the input. Much appreciated.
Robert
