Orion BF866 spring location?


Recommended Posts

I have nearly rebuilt this Orion BF866 which is now running but when I stripped it and removed the day wheel there was this spring just lying underneath (indicated by pointer). I'm sure it should be under tension somewhere? Does anyone know please?

Thanks Watchweasol. Looks like I have the wrong spring! From the tech sheet I'm missing 2575 date jumper spring and 2576 date jumper. I guess the jumper fits under the guard to the left where there is a pivot (which has a washer now and is how I found it) and the spring then probably goes in after the guard is fitted in the void above?

Looks like I need to find a donor.
