Thank you for the explenationsons! I'll try that. About the casing, I checked after you mentioned it, it's OK. There was just string of dirt. Thanks!

It's true that wear is not so likely, they are not sitting in an engine after all. My thought was more some sort of damage, since there is a slow sort of vibration when I turn the cog wheel. I suppose it's not very expensive to change them? Just to be on the safe side...

Hi! I have bought a second-hand mount and I'm trying to make it work OK (found problems as soon as I tried photography). As it's the first time I deal with this type of mechanics (has mainly been in cars and boats before 😝) I am bit lost... The worm gears, when I turn the cog wheel on the right, it does not turn effortlessly and smoothly (I imagined it would) but with a bit of resistance and with some "choppiness"? A bit like turning a ratchet wheel, it's a bit hard to describe... 😬 Is it normal or do I need to change the ball bearings? All advise is welcome Thanks! Magnus PS. Then I need to adjust the gears, but that's next step
