Need a service manual for this lens - Nikon 80-400mm f/4.5-5.6D ED VR AF Zoom-Nikkor Lens

Jeff, to assemble a lens, you need a collimator to make sure all optical elements ate correct in place. You need skills and a manual, to be able to adjust all lens elements in a correct order.

Asking this question, I'm sure you don't have a manual, a collimator and you miss the skills. So if you don't want to end up with a pile if glass, unable to act as a lens, please don't try this yourself. Even Sony will not reassemble the lens if you took it apart. If you really need a lens to b cleaned, please bring it to a Sony certified service centre and ask them what it will cost to clean / replace the lens.

This is the closest I can get.
But as long as you don't have the tools. Only think of a collimator, as one of them, you should not open a lens. Just a repair manual can't help. Would you operate on your own children, if you had a detailed manual, written by the best surgeon?
And if you are a surgeon, do you think you have enough electronic, mechanical and optical skills to repair a lens?

hello, you can download the service manual for sony alpha nex-3 and nex-5 from the below link:

You have to be an authorized Nikon repair center to get the manual.

Unless you have a lens collimator and other equipment needed to ensure proper alignment when reassembling the lens, I strongly suggest not doing the repair yourself. Take the lens to a good camera shop and have a properly trained and equipped professional do the job.

If you've had this lens for some time and used it regularly you may have a cracked or broken ribbon cable connector. If the lens works OK in manual focus this could be the answer. You'll need to get the ribbon cable replaced.

You must have service manual copy in hand for safe disassemble of lens mechanism of camcorder, please contact nearest Panasonic service center for service manual copy.

The only problem with ordering parts and doing a repair yourself is the re-assembly. Upon reassembly you will need the Nikon software and hardware to adjust and recalibrate the lens. This is not readily accessible as Nikon keeps this under lock and key for authorized service centers only.
