Beware of tightening bolts!

[stanleyjohn]

I figured today that maybe a loose bolt might be causing alittle slippage when moving dish so i tightened polar mount nuts,mast nuts,etc and when i went inside to check some stations poof!!! lost most of my ku and c .Well! after cooling down abit knowing that something was off i went out again to see what happened!I had to redo two adustments!one was the dish elevation was off and the mast mounting nuts also needed adjusting.I was lucky and it took me only half an hour to get things just right again.So!! when ever you decide to tighten or loosen some bolt!keep an eye on the tvs Q.

That is also a good way to tweak the dish, or at least I have used that method a few times

I tightened up some of the bolts on my H-H BUD a couple years ago. I did it in the summer, and it seemed to take a little bit of the looseness out of the mount, so I left it that way. Problem was, that in the winter everything contracted, and things were really tight, so that the motor could barely move the dish even at the top of the arc, and when I went close to the horizon I couldn't get the thing to come back. So I loosened them again.

I realized I was tweaking my 7.5 ft Perfect 10 dish yesterday while tightening the pole mount bolts, thus throwing everything else off. The mount cap is a not a tight fit on the pole.
There are 6 bolts arranged in 3 pairs vertically. I left the 2 southernmost(the dish face side) bolts for last to tighten after readjusting the azimuth. This holds the slightly loose mount parallel to the pole better I think.
Until I had done this the elevation & declination fine tuning weren't making the difference I needed in Q.

And there is such a thing as overtightening nuts and bolts. Especially if they're aluminum. Just ask any Paraclipse owner that has overtightened the pole bolts. Don't want to strip the threading!
