Found this page (http://thydzik.com/canon-efs-17-85mm-is-stucklocked-zoom-repairdisassembly/) which offers detailed re-assembly of the focus mechanism to ensure that manual and auto focus work:<br /><br />//quoted<br />1. Do as the guide tells you and strip everything down to where the loose screws are accessible. [The zoom problem is caused by a loose screw on the side of the "guts" of the lens (photo provided on above page.]<br /><br />2. As thydzik wrote in the comments and posted a picture about: http://thydzik.com/images/canon-17-85mm-repair-the-final-screws-that-need-tightening-th-pin.jpg<br />A 1 cm black plastic pin is marked with a green circle. Move this pin to the outermost position.<br /><br />4. Position the two silver prongs, coming from the autofocus unit (the unit in the left side of this picture http://thydzik.com/images/canon-17-85mm-repair-outer-casing-removed-from-inner-lens.jpg) so they straddle the black plastic pin.<br />If these parts aren’t put together correctly, no focussing will take place since the focus engine/manual focus grip isn’t moving anything around.<br /><br />3. Set the focus on macro and the zoom to 17 and put everything together again.<br /><br />4. Voila the world isn’t blurry anymore!<br /><br /><br />//end quoted<br /><br /><br />Hope this helps you!

The outer end of the sleeve barrel where you attach the UV filter is cracked. I plan to buy the sleeve barrel from canon to replace it myself. Does anyone know whether i should start to disassemble from the back end of the lens or the front of the lens.

It takes a lot of force to unlock it (and you will grow a beard whilst unthreading it - even if you are a lady).<br /><br />Use a high quality product to clean the glass (like eclipse fluid) and a magic cloth as this combo will leave no residue or ugly streaks on the glass. <br /><br />Good luck with it...<br /><br />MarvinMarvin Africahttps://www.blogger.com/profile/11543696676410277625noreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-627306096618199832009-08-18T11:19:51.153+01:002009-08-18T11:19:51.153+01:00Hello Piratekaya,

It is obviously an important connection between the auto focus motor and circuit board. <br /><br />...maybe worth heading to Ebay (or other auction sites) for a cheap replacement!<br /><br />These lenses are slightly tricky, but not impossible to focus manually.<br /><br />MarvinMarvin Africahttps://www.blogger.com/profile/11543696676410277625noreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-34947693785497945622009-07-27T18:02:31.399+01:002009-07-27T18:02:31.399+01:00I got this lens from someone who it fell in the oc...I got this lens from someone who it fell in the ocean from. The lens had 2 water spots inside it, and the auto focus was not working. I soaked it in distilled water first for 2 days to try and get the salt water off. Water ended up getting inside the lens element. I am still hoping that it will dry out. <br /><br />I searched on google for repairing this lens, and I was happy to find your tread and took the electronics apart. I cleaned everything with rubbing alcohol and put it back together. The good news is that my auto focus is working again! <br /><br />I still have water spots inside my lens element though, and the camera can not "see" anything through the lens. I need to make a tool to remove the front element and clean the optics manually. I will update you on the repair in progress.Roopshttps://www.blogger.com/profile/05050784731907913748noreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-18471227571663347262009-07-27T11:58:41.246+01:002009-07-27T11:58:41.246+01:00I stumbled across your blog while looking for info...I stumbled across your blog while looking for info on repairing this same lens. In my case my toddler had dropped my 350D a couple of feet to a hard floor and the focusing tube had been knocked off of it's rail. After reading your article I decided to just open it up and have a look, as like you I had little to lose by trying.<br /><br />I had to go a lot further than you however and virtually stripped the lens right down (although it turns out I didn't need to). I got the lens straightened out, but unfortunately it now doesn't auto focus.<br /><br />About half way down the lens is a metal contact with 5 'finger' contacts the run across some rails. In mine they are all bent up and beyond repair when they have been forced in a position they shouldn't be in.<br /><br />I'm pretty sure that this is part of the auto focus, so it might be worth you having another look there however to see if there is some minor damage to the contacts in your lens. Just one screw keeps them in place but be careful as it's pretty delicate.<br /><br />Anyway, nice blog you have here. I'm just getting started with macro photography, so I'll be back to read some of your other articles soon.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-17775202436622659122009-06-24T17:07:31.032+01:002009-06-24T17:07:31.032+01:00Hello Kansas A,
Sorry for the delay...I've be...Hello Kansas A, <br />Sorry for the delay...I've been very busy. I've always enjoyed taking machines and devices apart to find out how they work. My fist tip would be to always use the correct tool for the job. This applies to all aspects of life not just for electronics or photography. <br /><br />The problem of course is putting them back together. My top <b>tip</b> is simple: take photographs at each stage in case it gets too complicated. This can help with complex configurations and wiring when reassembling the gizmo. A camera can be a really useful device! <br /><br />Another less helpful tip: don't hold your breath for too long, you might turn blue.Marvin Africahttps://www.blogger.com/profile/11543696676410277625noreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-43144909908289402482009-06-17T05:34:50.805+01:002009-06-17T05:34:50.805+01:00Oooo I have been where you have been :) Not speci...Oooo I have been where you have been :) Not specifically taking apart a Canon lens, but many electronic pieces where I sort of hold my breath throughout the procedure praying that when I get it back together it won't be worse than when I started ;) Great post! lolKansasAhttps://www.blogger.com/profile/11860041177272594310noreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-63929568889528025432009-04-11T19:43:00.000+01:002009-04-11T19:43:00.000+01:00Hello Urmi,Yes, I managed to string a couple of se...Hello Urmi,<BR/>Yes, I managed to string a couple of sentences together on the subject :-)<BR/><BR/>I've also made the first prototype of my bracket to hold my Sigma EM-140DG away from the camera & lens.<BR/><BR/>Sometimes when you buy electronic goods their is a small sachet of silica gel in the box. It always says <B>do not eat</B> on it, which make me wonder what one would taste like. Anyway, I suggest collecting these sachets & keep them with your camera equipment to absorb any moisture. Then if you are lucky you will not be taking your kit lens apart in a couple of years time to repair it:-PMarvin Africahttps://www.blogger.com/profile/11543696676410277625noreply@blogger.comtag:blogger.com,1999:blog-4154313645067095510.post-8385046386172719402009-04-11T19:03:00.000+01:002009-04-11T19:03:00.000+01:00haha so you went ahead and wrote out a post on tak...haha so you went ahead and wrote out a post on taking apart the lens :)) I have bookmarked it for future reference (and for a chuckle :P)<BR/><BR/>"When I did manage to rebuild the lens the auto-focus was still not working.
