From memory, Olympus cameras are pretty well laid-out inside, so minor repairs should be doable.
But from experience when trying to fix a Trip35, the success rate is not guaranteed on those.
Thing is if you have to get inside the lens for the repair, you're definitely looking for trouble. To access the inside from the front, under the lens bezel in the center of the meter ring, there are screws that are glued with white paint. To remove those screws, you have to unscrew the lens elements. But by doing so you loose all focus indications, so the lens needs to be collimated. But the camera doesn't have a B mode. So you have to peel back the front leather to access the lensboard screws. Once the lens is loose, if you haven't broken the meter wires yet, there is, from memory, a barrel piece with a small hole in it. You rotate it until the shutter is open, use a staple to keep it open, screw the lensboard back, collimate the lens, lock it in place using the set screws on the lens bezel, remove the lens board, remove the staple, re-screw the lens board on and re-apply the leatherette.
That's the reason why I've had a broken Trip35 on a shelf for more then 10 years...
