For those who have an old Nikon with a sticky low speed escapement, you can usually free it up by removing the back, then taking the 4 screws off and removing the bottom cover. Enough of the escapement is visible through access holes that you can simply dribble some lighter fluid on the exposed parts of the mechanism, and then fire the shutter a few times. In 90% of cases this will get it going again. In 5% of cases you'll need to repeat the process a couple/few times, and the remaining 5% usually means a mechanical problem which requires repair of the escapement.But a big thumbs up on showing how to get the mirror box off, and how to get into the inside of the camera.
JP Guthrie, thanks a lot for that easy solution. Few days a I inherited a 1970 Photonic with that problem. I tried your “easy solution” and BINGO!! It works. Thanks a lot!!! Mikeno62, thanks for both videos. I don’t dare to dismantle the camera as you did but I was hypnotised during all the process. Thanks!!!
My nikon f has no issues when shooting from low to high speed. However whenever I use the self timer the hi shutter speeds are not consistent when it shoots.
#mikeno62 Hello, maybe you can solve a doubt for me. My Nikon F, in position B (bulb), shoots but the shutter does not stay open, neither the mirror up, it shoots with a high speed, can I do something to return the operation to position B?
Hi Kenneth, your lens CLA videos have been my tutorials for fixing my old Nikon AI and non-AI lenses. So greatful to you for sharing. I have a factory new, mint NIKON F body that was not used most of its life. The mirror sticks in the up position at speeds slower than 1/30th second. Any ideas what could cause it?

That's actually great info, and a more simple way to fix the camera.

Thanks, great solution. It really works
Great repair video! You make it look so simple!
Absolutely fantastic work! I'm admired for your patience and capacity. You also make your own harware! AAA+++
thank's Ramon, yeah I will never be finish with thinkering with those camera's and lenses (and tool's), it's great fun :-)
that spring at the end was not playing ball have to watch part 2 cheers for sharing your passion mate
Yes great tutorial, the dots on the self timer surround allow the self timer to be set to approximate intermediate values
Thank's for the info :-)

Wow, I thought mine looked rough!

The gears that are in the Nikon f are they the same type of gears that are in the nikkormat fn?
Your videos and patience is superb.... do you have a repair equipment business open to the public? Where are you located
Denmark
Brian Larsen long way from Mexico
Based on the body’s serial number, I’d say that this F body was manufactured in 1964.

I have the same issue and would love to know how to fix it.
Check the bumper foam. If worn it’ll make the mirror stick up
Same issue with mine, I've been inside a few film cameras but I'm not touching my F, she can stay sticky as long as she's still working (kinda)
Great Tutorial !! With this tutorial as guidance I will now be able to repair the "sticky" 1 second shutter speed on my "F" 7442551. Thank you !!
