The n-s axis is fixed because once set you don't need to mess with it.
There are two adjustments on the n/s.
The first is the polar axis. It is adjusted to match your latitude. If you are at 45° lat then the polar axis needs to be set at 45°. This axis is parallel to the Earth's axis. Get yourself an "inclinometer" with a mag base at Home Depot. They are cheap.
The second axis is the "look angle" axis which allows the dish to look at "The Clark Belt" over the equator. It's on top of the polar axis hardware.
Set those two axis with the inclinometer while the dish is in a vertical position. Then all you have to do is adjust for the "azimuth".
I posted an old video of the guy from the show "Bore Site" that shows how to adjust for azimuith, but it has been a while so I don't know where it went. Once set correctly you don't have to mess with those adjustments again. That's why there's no 'lectronic adjustment for them

Do not grease the worm drive and big drive gear. This will attract and hold on to dust and sand. This will cause excessive wear on the large drive gear, as it is only made of plastic. Believe me I know. How is the motor on there still running?
