Few weeks’ back I bought a Yashica Mat 124 G for less than 100 bucks. The camera is in good working condition and light meter needle also moves when putting a new battery. Whenever I tap the light meter is works and then it stops. So I decided to take a major risk and removed the View Finder to get access to backside of the light meter. That when I saw the problem. One of the two joints of the light meter was broken. Being adventures I unscrewed the light meter and removed the broken piece. I attached the light meter back with one screw.
Now when I check, both needle moves and red one is sensitive to light BUT the readings are way off. For example: in bright daylight, both needles align when Shutter Speed is B and Aperture is 3.5
Below picture shows how the meter setup looks now.
Can anyone with experience in repair please help me out?

Perhaps you have the gear around the bottom of the meter movement engaged with the wrong tooth of the gear sector to its right which connects to (I think) the aperture selector. When held by only one screw, does the meter stay in position well enough to keep these teeth from slipping out of mesh? |

Thanks Rick for responding back,
The meter seems to so far hold still with one screw.
Your explanantion makes sense to me but how do I set this right?
Do you know of any repair manuals for 124 g

Here's a rough sketch of the meter mounting arrangement (still with 2 screws) - you should be able to loosen it, pull the gears out of mesh and re-mesh them in another position until you're in the ballpark. |
