Gh700 grasshog trimmer - round plastic gear drive broke in half - can I get a replacement or even a metal gear?


Same problem; GH700 with a stripped gear, inside the casing.
I wish places with replacement parts sell uncommonly broken pieces... I didn't have an account for commenting a request in that site.
If someone asked them, it could be available in a matter of time.

Camera lens can't focus


The lens is driven by small chips and gears. Usually, the lens will get jammed when it tries to go out, and something will give, usually a plastic gear. When that happens, you have to totally disassemble the unit to replace it, and it's a heck of a job. The only other things you can try is to blow with compressed air, and hope it's just some dust impeding the proper location of the lens. You can also try to pull on the lens, as it comes out, hoping to reseat the gears and such. However, if a gear tooth is broken off or some other part is broken, it has to be replaced. In that case, better to buy a new one, they're coming down in price all the time. Good luck!

Lens error: camara has broken gears in lens assembly


Hi kevin3738 and a_nester

ok for kevin3738,
im thinking that since you said your lens doesn't extend all the way out that maybe you might have cracked a gear in the lens housing, the mechanism to extend that is located when you open the camera and take off the front face plate, on the right side of the lens housing **silver part** you see a black plastic casing attached to a motor on top and screws in it, that is what moves the lens housing in and out, in that are a few gears, i think 4 of them lat move the housing, 3 small ones and one big one that reaches down to the bottom of the housing, they are interchangable but im not sure as to where you could find a gear to replace the broken or cracked one,

And for a_nester
im gonna take a guess at what exactly the problem is on your camera, and it might be the lens autofocus
in that case you can look here

Problem with fe-210


Lens gears are probably broken off, or other problem with lens. Will need to replace lens, or may possibly be repaired. I've repaired a few lenses with gears broken off, by replacing broken off posts with similar size plastic pieces(drilled holes and super glued in place, being very careful). Still working months after repaired. Olympus repair shops can replace anything needed, but at a HIGH price; sometimes cheaper to replace camera than to have them work on it.

Used FE-170 hardly powering on.


The lens need to be replaced or repaired. It is not fully extending. It may be that one or more of the plastic gears or plastic rods that hold the gears in place, are broken. I repaired two plastic rods in my lens, by drilling holes for new plastic rods,(I cut plastic rods from a plastic toilet bowl chain!!! It fit inside the gears perfectly), and super glue the rods in place. Replaced gears, put camera back together and BAM in worked! Nothing like a perfectly working refurbished rig job. Camera takes great pictures to this day.

My Optio won't stay powered on.


This is probably due to a broken sensor tab inside the lens, or a failed sensor. When the lens reaches the end of its travel a small plastic tab will pass between the ends of a C shaped sensor and let the camera know the lens has reached the end of its travel. You are not hearing a safety device, you are hearing the gears actually slipping. Don't let it do that too much or you will turn one problem into two problems quite quickly. If you cant find the broken part it will require professional repair. I would advise against taking the lens assembly apart. They are extremely hard to get back together and you very well may end up with a junk camera. David Millier Advance Camera Repair
