Hi guys,
I did a service on my mount around 6-8 months ago. Replaced the bearings in the mount and changed the grease etc.
After this service the mount performed alot better than it had previously. However I watched a video on someone hypertuning an EQ6 and realised I had put grease on the clutch faces... (Not that I was having any issues with my clutch).
I decided to pull my mount down to clean this grease off and noticed the Dec axis bearings in the ring gear were rusted.. and one was seized onto the shaft
. The ring gear was also discoloured black.
Now the mount had been stored on a pier outside, but under a cover where no water could touch it.
Do you think this rust is a result of moisture getting into the mount? (RA axis was perfectly clean. Would of thought if it was moisture it would of had some signs also..) Could it also be a reaction from the grease I used? Maybe a residue from the previous grease has reacted to my new stuff?
Anyway I was able to remove the bearings and treated the rust with a rust removal gel. Seemed to remove all the surface rust. I then polished the ring gear and gave the dec axis shaft a slight rub over with a green chux cloth to ensure everything was smooth and clean.
Have since put the mount back together but haven't been able to test it due to weather.
But thoughts on what may of caused this? I'm reluctant to put it back out on my pier if it's going to cop that kind of damage in a few months. ( I done the rebuild 8 months ago but the it's only been pier mounted for the last 3 if it's lucky.)
Really concerned right now and am going to check the mount again in a months time. see if I stopped this corrosion in its tracks.
