Update did Andrews Mount after work today and we noted some differences. The Bearings were all seized up, could not get them to move at all with the fingers. Mine would move if with a bit of force but Andrew's would not budge.
There were signs on the RA and DEC shafts that the were just slipping on the bearings. Anyway a bit of elbow grease and some Alcohol got the bearings rotating more freely. Also cleaned all the other washers, gears, worms etc with Alcohol. Then greased everything one by one with Slick 50 and put the mount back together. Now its Buttery smooth.
Some photos here.
1. Dec Axis lower Bearing, not how this is all the way to edge. This is the way it should be. Some older mounts the bearing was further in. Some times this was fixed by adding a third bearing if there was enough room If not you have to get this bearing out and replaced it.
2. Dec Axis and RA shaft assembly.
3. Dec Shaft.
Both shafts are cleaned with Alcohol and greased with Slick 50.
4. RA Axis, RA gear and RA worm post cleaning and greasing with Slick 50.
5. Greasing the RA worm.
6. Peter finishing off the RA Axis.
