yashica mat TLR

LENS · 31st March 2008

Hi guys,

I got a yashica mat..and try to learn more about it.

I have read that manual, there is a 'take-up spool' that can be removed, is it something comes with 120mm film roll? one of the yashica mat i got is without it..so is it a standard part of camera?

I read about that yashica mat seems have problem in crank winding..

I have some question which i can't find answer from manual..

when i didn't put the take-up spool inside, the crank can be wound clockwise non-stop, and when i put the take-spool at the upper film chamber, then it will stop at some point, and i can wind counter-clockwise to **** the shutter.

so i wonder which position the crank should stop when it is wound correctly?there is the film counter, when winding clockwise without problem it is almost back to "1 o'clock" position, sometimes "12 o'clock" position. However, sometimes it stops at "4 or 5 o'clock"position, and i have to wind back and press the shutter (shutter won't fire in this situation), and the crank is free to wind again..

Just find the crank mechanism is a bit irregular, is it related to the take-up spool? or will a CLA can make it smooth?

hope some yashica mat users out there will share their comments.

yes bro, the take up spool you can still from any 120 roll film.

As far as i remember, when you advance then crank up for the shutter, the crank should be around 1 o'clock, u can fold it back to original position mean correct i think.

you can advance forever clock wise if no film inside i think, dont know about the point when it stop through.

Some of the old 124G needs some servising as the cranking is not so smooth. Align the film mark arrow to the red dot and you can have a feel. Yes its around 1 o clock position stopping after you crank about 270o.

You can take one old roll of expired 120 film and try to load it, crank and shoot. You can use the old spool as spare spools.

thank guys for replies..

it is 1 o'clock position after cocking the shutter.. however i notice that when wind it clockwise, it is not always in exact position. If judging by the film counter, i think mine is fully wind till 12o'clock and sometimes 1 o'clock position (like almost 360 degree), i looked at the manual, the manual seems to show it is stopped till 9 o'clock(270 degree).

However, it seems my crank will get stopped earlier than it supposed, and i have to wind back and press the shutter release button(shutter not fired since not fully wound), then i can wind clockwise again and wind counter-cw and the shutter is ready.

Hi, are you trying with just the paper backing only?

The loose paper will cause the problem you described on most TLR because the toothed wheel in the camera is driven by the friction of the paper/film. If it is too losse, the inconsistency will cause the cranking erratic, aka, stopped at different angle.

However, if this happens to a fresh roll of film, then you need to check the tooth wheel in the camera. See if is dirty and needs some cleaning. If not, send the camera to a good service shop and get it fixed.

This camera is very old already and do expect some problems.

Hi Lens,

I experience a similar problem. Mine would get stuck sometimes even at the 3 o'clock and can see that the film is not advanced properly. Even when just loading the film, the film advance would slip as it is wound to the film counter 1 position.

I just brought it to Mr Tay (De camera Consultant) to take a look and he showed me that a gear was slipping in the advance. Maybe you might want to bring it to him to take a look.

Regards

Hi Jonathan, i just try to wind it with the 'take-up spool' only, i notice that there is obvious worn mark caused by the gear/tooth wheel..i try to observe the gear/tooth wheel, it seems pretty good condition.

Hi zenesh, mr Tay is in bedok right? i think you PM me the address before..i may just pay a visit.

thanks.

Send it to someone from ex-Tithes (ho ho that was so long ago)..... and knows the Yashicamat. Cameraworkshop is ok.

This is a typical problem with old Yashicamat 124G. My mint copy still give me problems.....

i try to put the 'take-up spool' in my other yashica mat and it winds okay without any interruption..but i notice that the crank will get stopped around 12 o'clock or 1 o'clock..instead of a constant position.. i will assume it is because the film advance is driven by the 'take-up spool' as i have seen worn gear mark on it, and since not gear to gear motion, the position is not constant.

I will take the other yashica mat for a check tomorrow..hopefully got a clue.

Hi guys just give some updates that may be helpful to others who had similar questions..

I visited the repairman who is kind enough to check for me. I realise that u can't verify the winding problem without a rolls of film..He helped to verify with a exposed and useless film. It seems the thickness of film is part of the reason that will affect it.

and i think for clockwise winding (to advance film), the clank will usually stop around '8 oclock'.
