Hi, Jeff. I do not know of any sites that offer detailed info on disassebling a lens. The best way is to just do it yourself. It would be good to invest in the proper tools first. A spanner wrench is worth it's weight in gold for working on lenses. You also need a good precision screwdriver set. Lowe's actually sells a nice one with a lifetime warrentee for only $5.00. It's in a black and red box. You also need some pieces or rubber for gripping different items.
The easiest thing to try first is to simply remove the rubber grip on the zoom/focus barrel. On a lot of lenses you can access and lube the glides through slots on this barrel. There may be some covers that are held on by tape running the length of the barrel. Once you remove these covers you can see the glides where you can apply some grease (not oil). You can also put some grease on the surfaces between the barrels. Most lenses have 3 separate barrels the slide inside each other. As you rotate the outer barrel to focus and zoom you can see these different barrels moving and rotating. Just lube any dry surfaces.
If you feel more adventurous and want to dig into the lens, once you get the tools just try it yourself, it's really not as bad as it looks. You may even want to pick up a parts lens on eBay to practice on. I started about 4 years ago working on lenses and I feel confident enough now to take apart virtually any lens and put it back together. Start by removing one part and then replacing it so you learn how it goes together. Do this one part at a time adding and replacing more pieces as you feel comfortable. |
