G-41 Obs+ RA Worm Support from June 2005.
The new support was introduced to make maintenance simpler. There is only one adjustment point (5) now.

1: M6x16, swivel point of the worm block, gently locked
2-4: M6x12, locked until washer is still free to move
5: spring force control, locked cca. 1/2 turn
Note: Loctite 243 is used on these screws to fix them.
Problem diagnosis:
July 2005. Gemini
