Does anyone know if these can be reasonably adjusted in the field and if so, what screws to loosen/tweak to do so? I really don't want to take the instrument in unless I absolutely have to for such a thing. The reticle is off enough to be an annoyance as well as making things miserable when weak traverse geometry is unavoidable.
Thank you in advance.
The only superior evidence is that which you haven't yet found.

OK, I will bite on that
1. get an old conventional transit manual... I found several by searching "transit reticle adjustment". Most all of them discuss adjusting the cross hairs.
2. turn OFF the electronic automatic compensation on your transit.
3. check your cross hairs. if needed adjust like in the old conventional machine... they are all the same.
4. turn ON the electronic compensator. check it again.
take your time, be gentle and don't get it wet or dusty inside.
If that freaks you out bring it to the shop. Then find some old timer party chief to show you how it is done.
Back in the 70's damn near everyone knew how to do it or had someone handy if/when the instrument took a tumble.
In '87 we had a Set2 get hit by a car, (hard, broke two tripod legs, BIG divot in the top of the instrument)... the chief called me, he found the manual in the truck, adjusted it and finished the job (a day travel away). The shop found no problems and said it was "in adjustment"...
again... If that freaks you out bring it to the shop. no shame in that
Are we talking collimation here?

collimation? I forget the terms... Hz. and Vert. cross hairs
I reckon I should clarify my question. What I'm looking for is which items on the telescope that I need to loosen/tighten/turn so I can perform the H & V collimations; perhaps someone has a Service Manual which would indicate these. I didn't want to wind up with a bench-full of expensive miscellaneous parts 🙂
Thanks for the responses so far.
