AVX - Is that Normal??!!

[Anthony RS]

Hello!

 

I've just discovered that there is slop on the AVX's DEC motor gear. Is that normal or should it be fixed and how?

 

Here's a video of what's happening:

I may be wrong, but every motor has a certain amount of play when you move the shaft where the coils are in and out, sideways movement is not normal i believe but in and out along the shaft is different, i just tried the same on my motors and there is some movement just like yours. Maybe in a high RPM motor that may be an issue, but a RA/DEC motor moves at almost imperceivable rates, i can't see that being an issue.

Don't think I'd see that as play as there's no way it would pull like that in real life..there's plenty of things on u tube to show how's it's best to make sure the gears knit together as best you can

It looks normal to me.
On this type of gearbox there is usually a bit of end float from the output shaft of the gearbox.
If the mount is tracking & slewing ok, I'd leave it well alone ? 
You could strip the gearbox apart and fit a couple of nylon washers to minimise the end float but I doubt it would give anything beneficial to be worth the effort.

Yes, that's perfectly normal.
