See: http://www.mailbag.com/users/ragreiner/decfixmajor.html
See: http://www.mailbag.com/users/ragreiner
for info on the Dec drive adjustments and related topics
See http://www.austin.cc.tx.us/astro-ES/AstroDesigns/
for info on general subjects and Dec drive topics

If more detailed information is needed, I don't know where to start.
This is a VERY open ended question that takes pages of text to fully
describe. I spent 3 hours on the Dec bearing replacement and optical
tube/fork alignment text to get it right. That actual procedure took
1-1/2 hours to do. Doc G spent 6 more hours editing and setting up
the illustrations on his web page. Doc G has since added more
material to this, so we have well over 12 hours of labor, not to mention
answering private e-mails.

Doc G has written extensive Dec drive adjustment procedures that
can be applied as needed. All are on Doc G's web page. Is there
anything missing?
