Repair: Nikon FE Camera Back Lock

Hello, everybody. It’s a rainy day today here in Tokyo, it’s actually very bad timing since it is the annual Asakusa Samba Carnival today! I was hoping for good weather last night but it seems that nature listens to nobody. Oh,well…maybe it’s going to be sunny next time.

Introduction:

Today, we are going to talk about how I fixed the locking mechanism of my Nikon FE’s film door. My Nikon FE is supposed to be sold but I accidentally soiled the camera so it’s going to stay with me for now. I also fixed some other things on this camera and I will show you what I did next time. This is going to be a series like the one I did for my Nikon F.

IMG_1435.JPGHere is the Nikon FE along with the Nikon F. Notice how small it is but I assure you that this camera is very capable. In fact, I would say that it has most of what the legendary Nikon F3 has when it comes to features.

My Nikon FE was bought as a junk from a Malaysian living here in Tokyo. It was dirty and it had lots of problems that needed to be addressed before you shoot a roll of film with it. It has one problem that has always bugged me and that is the lock of the film back and it is kind of stiff sometimes and it sometimes doesn’t go back to when you turn it. This doesn’t give me enough confidence as I may accidentally open the film back and ruin a roll of film accidentally so I need to fix this before I do a test roll on this camera.

Before We Begin:

If this is the first attempt at opening a lens then I suggest that you read my previous posts regarding screws & driversgrease and other things. Also read regarding the tools that you will need in order to fix your Nikkors.

I highly suggest that you read these primers before you begin (for beginners):

Reading these primers should lessen the chance of ruining your lens if you are a beginner. Also before opening up any lens, always look for other people who have done so in Youtube and the internet. Information is scarce, vague and scattered (that is why I started this) but you can still find some information if you search carefully.

I highly recommend that you also read my working with helicoids post because this is very important and getting it wrong can ruin your day. If I can force you to read this, I would. It is that important!

For more advanced topics, you can read my fungus removal post as a start. This post has a lot of useful information here and there and it will be beneficial for you to read this.

About Me:

I am a photographer based in Tokyo who scours the junk section of the camera shops here on a regular basis. I started this hobby of fixing old lenses and cameras because I kept on getting scammed before when I purchase online. This turned out to be a blessing because I now buy junk lenses for a fraction of the price and then fix them to add to my growing now collection. This allowed me to buy gear that were otherwise off-limits to me if I were to get them in better condition.

I was a scale modeller before who built models for other collectors for a very longtime, got an education as a dental prosthodontist (but didn’t pursue dentistry) and growing up in a watch repair shop gave me the useful skills that would help me in this craft. Fixing my car also contributed some know-how.

Having mentioned the above, I will tell you now that I am not a professional repairman! So please take what I do with a grain of salt and I will never be held responsible for anything wrong that will happen to you and your project. I hope that the pros would guide and teach us but nobody is writing anything.

As my collection of repair notes grew, I get requests from people with similar interests and from professionals who just needed some notes just in case. Now, I am sharing my library with you for your entertainment and reference. I hope that you find my work useful.

Repair:

Fixing this part doesn’t require any special skills but you need to have the proper tools or else you will risk ruining some of the parts here. Before you begin, you should have a small C-ring opener. C-rings can also be pried open with a pair of pliers but this is risky as well as time-consuming so you might as well just buy the right tool for the job.

IMG_1432Start by removing the film rewind lever housing. Use a screwdriver, dowel or a wooden peg  and stick it in between the fork inside the film chamber. This screwdriver or whatever you chose to use will lock the whole mechanism in place while you turn the film rewind lever counterclockwise to unscrew it. Do not unscrew it by using the lever itself. Instead, grab the housing and use your fingers to twist it off.

IMG_1431Once the housing is removed, slowly remove it from the camera because there are a couple of loose parts there that you do not want to drop and lose. From the picture above, you can see the pressure plate thing that keeps the rewind lever in place, a spring and a washer as well. Put aside these little parts and clean them up properly with lighter fluid to get rid of any dried up dirt or lubricant just in case.

IMG_1430The shaft is telescoping and is made up of 2 parts. You can simply pull it out of the camera and clean that one of you wish. Be careful not to damage this part.

IMG_1429This is one of those instances when you would need a C-ring / E-ringremover. Be careful not to damage this part and the plastic dial under that thing. I cleaned the plastic dial with an alcohol wipe to remove the dirt.

IMG_1428With the dial gone, you can now access the delicate parts under it. Please study the picture above to understand how this mechanism works. The lock is basically hinged to something and the spring is in charge of keeping it in place as well as making the dial that is linked to this via the slot return each time you turn the dial. A small part of this lock goes into a slit in the tube underneath it. This is how the locking action works so that you will not pull the whole thing by accident and ruin a whole roll of film. Smart, huh?

IMG_1427You can simply remove the lock with your hand but be careful not to damage that spring. I then wiped these parts carefully with lighter fluid and I also saturated a Q-tip with alcohol and used it to clean the tube inside and out. It got really dirty after several years of doing nothing somewhere.

Clean these parts with a Q-tip and solvent. Lightly lubricate the parts that get in contact with each other with spindle oil or a very light grease. Avoid over-lubrication because if the lubricant caked-up again you will have to open this thing again. What I do is dip the tip of a small precision screwdriver into a pot of spindle oil and just touch the parts that I wanted to lubricate. It’s that simple.

Conclusion:

This project took me a little under 30min to fix. While I had the parts accessible, I cleaned away the dirt and grime with a Q-tip or a toothbrush and now this part of the camera seem to function perfectly. I did however noticed that the film advance mechanism is a little off so I will have to open that part up as well just in case. I hope that you enjoyed this post and if you liked it, please feel free to share this. Ric.

      Hello, Angel. How are you? Check this out:

      This is for the FE but I believe that this should not be too different from the FE2. The FE’s advance mechanism can be accessed easily by removing the bottom plate after removing the 3 screws. Check and see if the interlock is stuck. I just cleaned mine. Ric.

    Hi Richard–Thank you taking the time produce an interesting and informative website! I just wanted to point out that the photo showing the pressure “thingy”, washer, c-ring, and spring shows the spring on top of the washer. According to the repair manual, the washer should be on top of the spring. If assembled as the picture shows, the film rewind lever housing will not tighten down far enough.
