Thank you so much for this video! I'm about to do the same repair on the same model. I love that you keep the "not so perfect" parts as well because it shows me what could go wrong and how to correct it if it does.
Recommendation for putting the aperture and shutters together at 51:46. Use some not so sticky tape such as Kapton tape. I used that to hold the shutter teeth(?) in place on the bottom, then put the rear of the fixture on top. The great thing about Kapton tape is that it really isn't that sticky, so when I removed it there was no tape residue left on the shutters. And even if there was, it would most likely be easily taken off with some ISO alcohol. Other than that, great video! This helped me clean the shutters on my MAT 124. Now i just need to fix the lever, and light meter... I guess that's the life of owning old cameras haha.
Thank you for posting this amazingly delicate and patience testing work online. I’m sure someone will be able bring their camera back to life. It also made me appreciate the professionals who work on these even more. Cheers
Thanks for another great video. Helped me fix my Yashica Mat that was only firing 1/500s and bulb. As a side note, it is possible to remove the leatherette in (mostly) one piece, but it takes some time and patience. First use a hairdryer to soften the leatherette and the glue, then apply some isopropyl alcohol around the edges until you can gentry pry the edge up with a finger nail or other implement that won’t scratch the paint, then repeat this process of applying the alcohol and lifting the edges until the leatherette eventually comes away. I was able to reuse mine, with just a small corner that ripped.
Thanks Carl, I also sometimes use the hairdryer to soften the leatherette, but it's a good idea to use Isopropylalcohol to soften the leatherette so it's more easy to pry off, without make marks on the painting :-)
Hey there! my yashica 124 has this exact problem (only bulb and 1/500 works) may I ask how you ended up fixing it? did you have to disassemble the whole shutter like in this video? any help would be appreciated!
@@jncocoa there are a bunch of pins that sit within slots cut into the ring, seen at 21:52. These move as you rotate the speed dial to give you the necessary shutter speed. One of these pins had slipped out of its rails and was stuck under the plate that rotates when you change the shutter speed so it wasn’t doing anything when you turned the shutter speed dial. I took this plate off and made sure the pins were sitting right in these slots and tested the shutter speeds worked before reassembling.
My Yashica-D has a faulty shutter and stuck self-timer. Your video is the closest and clearest I can find online. Thanks for sharing and it would definitely help my repair a lot!
Thanks for the video, very interesting. I would have liked to see you assembling the aperture rings in real-time, not speeded up because that looked tricky but otherwise a fascinating step by step video. I've repaired a few old cameras but I've never had to dismantle things quite so much, thankfully!
Its really amazing watching your videos.i have the yashica 124g in mint condition and in perfect working order. Its really nice to see how everything works inside the camera. Keep it up.
I have a 1957 Yashica Mat with a 75mm 3.5 Lumaxar lens and Copal mxv shutter. The slow speeds are off. I am getting PPP repairs to give it a CLA when Covid lockdown is over. An interesting video.
Your level of skill and understanding is mind blowing! I can’t believe how intricate and complex these cameras actually are. Truly an object of much beauty. I love my yashica 635 even more now knowing just how much is going on every time I compose, cock the shutter and fire it. Thanks for your great videos.
I just subscribed. I've watched a few videos now and I'm learning a lot. I love those old TLR cameras and have thought about fixing a couple. This is an excellent resource. Thank you!
Hey thank you so much for making this video. I was able to fix my yashica mat em that i bought yesterday with the help of your video. Keep up the good work man!
Hi Kenneth. Thanks again for this video. As it turns out my Yashica D had four spacers for the lens plate and one dropped into the side focus mechanics. So the whole side had to come off. Fantastic how serviceable these old cameras are. You’re video is really helpful. Thanks.
I have several yashica mats with the copal shutters.....They work but I want to clean them.....your video is excellent and priceless!......so are all your videos....I collect the Kodak reflex also....would love to see you rip into the Kodakmatic shutter.....thank you!
thank you i managed to clean everything and it's all working! just a request, if you could do a video showing how to calibrate focus on TLR's! there's nothing like this out there
@@pedrodutra4088 I saw a photo album of a guy repairing his Yashica TLR. He said 'when I was all done I used the autocollimator to verify/fix the focus'. That's neat, but certainly not helpful to me. (unless it simply says I need to find a real camera repair place and have them do it?)
Thanks for the detailed video! I just wonder that if the aperture blades and gears were lubricated with oil in the past, shouldn’t I re-lubricate it with something else after washing the old oil off?
Great video, I have a yashica 635, will that be the same from inside? To timer to work smoothly, by mistake I used wd40 from the outside. And I got myself in trouble. Now the wd40 is everywhere inside. What should I use to clean it off, alcohol?
Hi, mikeno62, I just acquired a Yachica-Mat 124 (without the G). Film was able to advance, but the shutter did not fire. I was able to press the shutter button, but leafs did not open in the lens. After pressing the shutter button, was able to advance to next frame. Still, shutter button can push, but leafs not open? I am wondering if this could be fixed myself? I searched up your videos but did not find this problem on Yashica MAT 124. Thanks
Incredibly useful video! I'm at the stage of removing the escapement to clean it (around the 58 minute mark) but cant seem to undo those slotted screws - my screwdriver is the right size but it just seems to slip over the top of them and strip the screws a little which is not good at all, and I dont want to use any penetrating oil on the screws to loosen them in case it gets into other mechanisms in the shutter. Just wondering what screwdriver you used and what type would be advisable for unscrewing bits of the shutter mecahnism? Thanks :) EDIT* Just spotted it - for others wondering its a Wera Flat Precision Screwdriver 0.3 x 1.8 mm

Hi do you have a medonstration on how to take apart this lens. I have the same exact camera but there is some cloudiness between the lens elements. Also if the rear coating of the lens is degraded on almost half of the lens should I try to take it off or what do you recommend I do. Thank you!
Hello! I have lost the flash sync spring that you showed how to remove at 25:09! How can I replace it?? Is it even possible to find a replacement? Will this mean that the camera will not sync with flash ever again? Please help! I havefound spring steel wire but don't know the diameter, 0.1mm, 0.2mm, 0.25mm. I wouldn't say it is 0.3mm because it seems too thick going by memory. Can someone confirm?
Hi! I took apart my slow gear in my Yashica Mat em (thinking it would come out in one piece like this model) but a tiny spring popped out and I’m not sure how to put it back now properly :( could you be of any assistance?! Thank you so much!
Thank you very much for this video. I managed to clean and fix a sticky shutter of my Mat 124g.

Thank you very much for going in to so much detail. I am certainly more encouraged that I can get my Yashica D working properly again.
I have the upmost respect for your skills and for the engineering that went into developing and building these great cameras.

Thank you ever so much for making this video. It helped me out a lot.
This video has been immensely helpful in working on the shutter in my Yashica-12 Thank you!
Thank you for creating these videos to help others.
Thank you for this video!! I'm trying to do more and more self repair on my cameras so this is super helpful!
your strong!!! tanks a lot! because of you i fix mine
great job! tusinde tak for such nice and relaxing video !
Fellow camera repair novice :)
Thanks Stanislav :-)
Chris Sherlock has camera repair videos and he uses a jig made of sockets for the assembly of diaphragms and shutters. Pretty quick process.
Yeah, I was thinking of make a gig just like Chris and try how it can be useful.
Thankyou very much I learnt a lot
thank you i managed to clean everything and it's all working! just a request, if you could do a video showing how to calibrate focus on TLR's! there's nothing like this out there
Thank's Pedro, the TLR adjustment is on my ToDo list.
@@mikeno62 Would much appreciate. taking the lens out sometimes mess up the focus, it's a pain!

hello mr kenneth did you have tutorials too repair stuck film winder? especially yashica lm film winder/crank
Thank you for your video. I'd like to ask: how are the aperture blades interleaved?
Thanks for the detailed video! I just wonder that if the aperture blades and gears were lubricated with oil in the past, shouldn’t I re-lubricate it with something else after washing the old oil off?
Very informative, thank you!
Excellent! Really like your videos! Godt arbeit!
You are amazing 👏 ❤ 💖 💕

QUESTION: If I don't open the shutter plate, and dip the whole thing in alcohol, to remove oil from the shutter and aperture flaps, will that work?
THANK YOU!

Also if the rear coating of the lens is degraded on almost half of the lens should I try to take it off or what do you recommend I do. Thank you!
Just curious, what does the washer 11:26 do? I checked the repair manual and they seems to be called “regulating washer”
They were put in to adjust the focus/angle of the lens assembly
Hejsa, fikser du også kameraer for andre? Vh Niels

Do we send them to you for CLA
My shutter is stuck in low speeds.
Hi! I took apart my slow gear in my Yashica Mat em (thinking it would come out in one piece like this model) but a tiny spring popped out and I’m not sure how to put it back now properly :( could you be of any assistance?! Thank you so much!
Maybe you can trace it with the repair manual.
What yr was this camera made , anyone know thanks.
1957
? Where do you find good screw drivers. I'm sick of the cheap junk.
You should get the JIS (Japanese Industrial Standard) ones. I recommend vessel brand. They're reasonably priced and good.
