I've been shooting these Yashicas since 1970 when we lived in Okinawa, and for the past several years have fixed & refurbished them and sold a number of them in Ebay. I recently picked up one in really nice condition but DOA. I've resoldered the white lead to the battery chamber and now the diods light up, BUT, something is amiss that I haven't run into previously. Without the battery, it'll fire at the default shutter speed, but with the battery installed, the shutter opens and stays open until I wind the film winder. Changing the F stops doesn't make any difference. Is this a mechanical problem or an electrical problem? I've noticed that the shutter button travels the entire length but at the end of its travel, I have to exert a little more pressure before the shutter opens. That's why I'm wondering if one of the shutter rods needs to be shortened or lengthened. Would appreciate any info that would help me locate the problem. |

Oh yes, I've noticed that the POD looks to have been replaced with a white plastic pad, but it looks as though the pad is a little thick. Could this be the culprit? |

Have you a service manual for this camera. There is a set procedure to adjust the 2 rods in relation to the shutter release rod. It sounds as if the switch rod is out of sync with the shutter release rod.
Send me an email if you want the adjustment procedure.
Cheers

Greg, I tried something else on the Yashica and thought it might work but it didn't. The shutter still stays open until I advance the fim advance lever. If you can send me the adjustment procedure, I'm open to trying it. I don't have a service manual. my email address is:
[email protected]
Thanks for the info. |

Just a little contribution for whatever it is worth.
Early models had a back-door release on the non-hinged end.
Later models adopted the more conventional "pull up the rewind crank" to open the back door.
The early models had a removeable fork at the cassette-end of the rewind crank shaft - and it was held by a screw cotter-oin.
In order to remove the top-plate the rewind knob has to to be first removed. Logic has it that the floating fork (as held by the screw cotter) must be removed. But don't waste effort because such logic is wrong. Just place a screwdriver across the fork and unscrew the film rewind knob. |
