Skywatcher Synscan mount

[CarolandDom]

Hi, has anyone tried to maintain/repair the Skywatcher Synscan auto mount? I need to take it apart to replace the fibre(?) board which has suffered water damage. If there are any useful resources - diagrams, pictures, videos etc I'd appreciate some pointers. I'm pretty sure the electronics still work fine however the board has swelled and the main base bearing has corroded both of which have caused the mechanism to seize.

To be more specific it is the seized bearing I am having a bit of trouble removing. I will try to get a picture on here.

Managed to get the bearing off with the help of some specialist penetrant. Worked very well considering the thing wouldn't shift by other means. On to next steps now.

by the way any advice on lifting the motor out - especially pictures - would be gratefully received. I found a post from 2012 on this forum however the pictures were missing 🙄

I'll have a look later as I'd thought there was a thread.

This is a rather long YT but does strip the mount head down

Now trying to remove the motor. Wedges are inserted between the base boards and I've sprayed the area around the base of the spindle with penetrant oil. A few persuasive taps to follow. This may split the upper board however I'm expecting this.
