I did it replacing the original bracket with 42 tube (from the dish), with the old mounting bracket from stab90. inserted 2 pcs 1" thick nylon blocks as spacer on each side of the arm and u-bolted the 55 tube from sg9210 to this bracket.
AS far as I can see there is no way to remove the tube from the shaft. I'm working on a modification to the dish, using the bracket from the old stab 90.
My stab90 died on a 36" dish. dish was stuck on 83w. long time ago i got an sg9120 for half price as a spare. but the shaft is 55mm.
any solutions as to mount this dish (42mm tube) on this motor ?
Well, I took advantage of few mild days & set it up on the roof. I can get everything from 30w to 110w where is another tall tree.
Hope to cover the rest of the belt in spring with the prime f. on another location.
S9 is doing good in moving the dish, but nano & xfactor do not move the dish...
disconnected the motor, set it up the dish elevation @ 41.2 as for 83w (true south) on a fixed dish.
Got good q and the dish (&motor), is able to find 85, 87, 89 but nothing beyond this point.
It looks like 38 or 38.5 dish elevation info are wrong !
I'm assuming that the shaft on my hh90 has the same bend. The site of stab gives me the dish elevation @ 38.5 & dishpointer gives me 38 based on my geo location.
I guess that these numbers are taking this bend into account.
What I do not understand is: Declination Angle: 6.5°!
Why do I need...
So, where should I count the 6.5° declination: to the dish or the motor ?
(To the motor latitude scale makes sense for me in oder to bring its axis parallel to the earth!)
Not according to the manual: one side is latitude scale for 10 to 45 & the other side is latitude for 45 to 70!
I do not understand "motor elevation"??
