Olympus OM-1 - Improper Timing at Low Shutter Speeds

E-26
2) Adjustment of CA8576 (High Cam)
When a certain shutter speed takes longer than the proper timing, hammer
out the appropriate portion of 8576, and when shorter shave it.
In case of 1/1000 sec. widen or narrow the appropriate section.
For adjustment of 8576, remove PUK1.4 x 2SO, then 8576 will come
off singly. See the Figure in E-24.
6. Improper timing at low shutter speeds:
1) Adjustment required for proper positioning of the Governor.
If the speed at 1/30 - 1/1 sec. is in average longer (or shorter) than
the proper timing, an adjustment is made by moving the governor.
When it is longer, the governor is to be positioned rather towards the
direction A, and when shorter towards B.
Checkup
Refer to the Inspection Standard for the proper timing and make
measurements with the shutter tester.
(For reference: See the picture above for functions of the
individual levers for the Governor.)
