Just got done fixing my blurry camera ! Thanks heavy haul for the info . Ok unscrewing the camera is the hardest part . Only because I was afraid of breaking the lense but once it break loose it gets easier ,base of the lense will get a little damaged but not a problem . Once lense was off quite a bît off white powder came out of camera frame at least a gram not sure what it was probably for moisture . Cleaned lense and camera with Q-tip and alcohol .
You need to adjust the lense on the camera before putting back on the handle. I had some one screw the lense in and out while I was inthe cab until camera was clear . Marked the lense to the camera frame with notches , unscrewed ,counting turns . Put a o-ring on , screwed camera back in counting turns align notches and your good to go
