I'm not sure what you're question is. The repair requires a complete disassembly of the lens to remove the focus motor assembly. Then you need to disassemble the AF motor assembly to remove the broken rollers. Since there are no replacement (this parts a trade secret). Now you get to put it all back together again, calibrate it and make sure it will continue to work and never have the same problem again. (That's the fun part ). I've done a lot of these.
Hi. Thanks for your information. I was asking about cleaning the contacts as someone had mentioned that. My problem is intermittent but happens with my D750 and D500. It has been hit and miss. But it has been happening for a few months. Do you still think that it is the rollers? I am in Canada otherwise I would be glad to have you fix it. Thanks.
