Nikkor 18-55mm DXII Bayonet ring replacement.
The three plastic lugs have been broken off the bayonet mount. This is a very common problem with this 18-55 Nikkor kit lens. The good news is that it is only £9 + postage for the replacement part. You will need a size 0 PH screwdriver to replace it. No soldering is required.
Put the new ring back with the ground wire re attached
Remove the old Bayonet ring using a 0 Phillips screwdriver. There are 8 screws you need to remove.
Remove the screw that attached the spring loaded ground wire. The new bayonet ring comes with a new spring and pin.
Remove the screw on the ground wire to disconet the bayonet ring
The old bayonet ring is removed. You get the plastic ring and the metal AF lever in the package from Nikon.
Put all the screws back in and give it a test. Its a good idea to use a rocket blower to dust off the rear elements before you test it too.
