Issues with Altitude assembly in older G11

 

Thanks, Brendan. That makes sense. I seem to
recall that the manual didnt mention slackening or tightening these screws.

A Happy New Year and Clear Skies in 2018 to all!

Hi David....if you have the 2 bolts each
side. Usually you can leave the pivot bolt a
little loose...not much just a little and undo
the upper tangent bolt a little to make altitude
adjustments, nip it back up when done.

From experience, leaving the lower bolt a
little loose is ok but nipping the upper bolt
when altitude adjustments are done always
throws out the mount out a little in
"Alt". You get a feel for how much it moves
when tightening and allow for it. Also no need to over tighten.

It ius also thrown out in "Alt" depending on
which side bolt you tighten first. One side
thrusts it one way the other the opposite. Its
just adding a little twist to the mount to throw
out all your precise adjustments!

Grrrr

Paul,

I'm pretty sure nobody cares that? he counterweight safety screw and washer are not in place in a photo being used to help ID the different mounts? How does your comment help or promote solving the OPs G11 mount altitude problem? Comments not on topic make the thread confusing to read.??

Norm,

The amount of backlash in the G11 altitude adjuster is controlled by the endplay of the threaded rod which is captured on the inside of the base end plate with a collar and thrust bearing and on the other side by another thrust bearing and the adjustment knob. The gap between the end plate and the knob or inside collar is the problem, close this dimension and tighten the grub screws (a little removable thread lock adhesive helps) and all will be as good as new.?
