    Had the same shutter error with my D40 and got it back working by just jiggling the red wheel (not turning it) and adding a drop of wd40 on a screwdriver head to direct the liquid, put a lens on (doesnt matter if its a prime or a AF-S lens and hey presto back working again and closed it all up again.

    il probably send it off for a clean up anyway but for now im back shooting.

    We are getting a LOT of these cameras in for repair where the user has completely soaked the inside of the camera with WD-40. It pretty much renders the camera unusable. The problem is not with the gear, but with the weak design of the motor that drives the gears. It developes a dead spot on the motor brushes and will not move unless it is turned slightly to get away from the dead spot, but it will usually end up hitting the same spot again, causing the problem to come back. The only real solution is to replace the SQ Drive Unit which includes the motor.

    Hi, Thanks for all posts... I do not know if it's related to the same problem just mentioned by bobkilbourn (that needs to replace the SQ Drive Unit) but after I got about 20 of those messages, they simply disappeared, unfortunately the pictures I could take afterwards were always dark, even with flash (unless extreme long shutters) in case it's related to the same problem, I will appreciate your feedback.

    Shortly after i got my d40 back working it happened again and had to be sent off for repair
    4 weeks i took, and at 178euro cost, inc postal

    Since the repair ive had Zero problems.

    the whole thing about taking off the bottom and touching the wheel may work for a bit but if you have clients or a important shoot coming up....Send it off and get it fixed and also check if they will accept installments for payment to help lighten the cash drain.

    That's more than the body is worth, I would have put the money to a used D40x or D80 which i've seen for around 40 Euros more.

    I have finished disassembly of my D40x to unzip the shutter gears, but it will not power up to check if it fixed it. Anyone have a suggestion?

    Gentle People, Send the camera back for repair. Mine has had NO problems since repair. It is worth it. Good service return system in place. go to nikon website.

    this whole wd-40 thing is a fluke. the red gear is not just an ordinary gear to fix with oil. touching it may change the shutter's timing. it is like doing the engine tuneup to the car without seeing the engine's specs. Bobkilbourn maybe right. sand gets in my d40. i brought it in hidalgo manila and they fixed it right. it never had any problem since then. protect your slr in beaches. the place is a killer of slr.

    I got mine fixed, applying Silicone grease to the white and the red gear. I used Silicone grease from a fishing shop, the type used to lubricate fishing reels.
    Removing the metal plate is easy, just remove the 4 screws on the 2 sides of the body and the 2 screws in the SD compartment, then you can release the rear cover, and you have access to loosen the 2 screws holding the metal plate to the PCB.

    jus75, how much does the repair cost you in hidalgo? which shop?

  12. AccomplishedNovice 56 months ago | reply

    I have a D80 with what I think is the same problem, it happened before and I got it fixed for about US$140, and now it's happened again maybe two months after. I tried opening it up but I don't see a red gear only very hard to reach white gears...sigh...I tried as best as I could to get some WD-40 on them but I'm not really able to move or touch them...has anyone else had any problem with the D80 and how did you resolve it??

    I have a D3000 and have the same problem. Will this fix it? I don't want to open my camera and then not be able to find gears.

    Hi all. Have read ALOT of these comments and complaints about this model (D40, D560, etc.)> I am wondering: has anyone complained to Nikon why they have not isued a recall for repair. It is plainly obvious that this is a major design/materials flaw that they should repair/replace on THEIR nickel, not mine!

    I just wanted to confirm that indeed this method works (call it fluke). On my D40, I didn't had to go as far as removing the silver plate instead just greased the red cog wheel using a needle. You can use any lubrication in moderation. I am not sure if its the lubrication that fixes it or the fact that it goes out of timing and so moving the cog wheel forward and back several times manually fixes it? Please note that you can only wind the wheel back and forth to a certain degree so, forcing it might break it; be careful.

    Took me a while to get rid of my error but I continued applying grease at very small quantity and continued manually moving it with needle back and forth. (You can also use toothpick - probably safer).

    Also played around with changing camera modes from Manual to P - not sure if that helps.

    n wat if wd40 is not available.. can we use ne other lubricants??? like machine oils??? :/

  19. hooked_beauty 37 months ago | reply

    I must be one of the last surviving D40 owners... I just fixed this issue using your page. My D40 shutter started sounding stiff, then did this gear jam business! I opened the back, moved the red gear and felt it being rather stiff. I then applied a single drop of synthetic lube, rotated the gear, took some test shots, and closed up the camera. It works! Thanks a zillion.

    Oh and guys, I had to do a lot of fiddling, and WD-40 didn't work at first. So have patience when you work on this repair. With determination, you can do it!
