Hi, I've just been succesful in restoring the meter and shutter to working order on a Ricoh 500 ME that fell my way. The last job that needs doing (besides the light seals) is somehow tightening the lens barrel which is very loose. However, I can't see where to start on this and I don't want to start hacking. Its mainly the front lens assembly thats loose that includes the focusing ring (the one you grip to change focus) and the aluminum filter ring. Any pointers? Thanks |

I think your camera is a 500G with some minor changes.
Unscrew the thin ring that screws into the filter threads. The name plate around the lens along with the cds cell and the aperture slide can be gently prized out. You will be able to see the mountings for the outer lens barrel, ie 3 screws that thread into brass posts. These are often loose or fallen out altogether. Refit them using some sort of thread locker or laquer to hold the screw heads.
Cheers

Yep, Greg's got it. The ring he means is the thin castellated ring you'll see if you peer down the barrel - you can probably move it without tools if you have long nails, but it's delicate so be careful!
I don't think there is anywhere a screw loose in the assembly can totally escape from, so if you can't find all the screws keep looking and tap it gently to dislodge anything - it took me a little while to find my third screw, which was lurking in a corner.
It's a nice simple job, and the camera feels so much better-built when you've done it! |

Castellated, yes that's the word. So much more eloquent than "thin ring". Thank you for the ammendment.

Always glad to be of service, Greg! Actually, it's the word someone used when they came up with the same repair over on Rangefinder Forum, and I grabbed the camera and did the job there and then in front of the computer! It's a little like re-doing light seals, in that you get a lot of satisfaction for relatively little effort. Hopefully Elwrongo is out shooting with it already. |

Hi Guys
thanks for the help, my internet's been down for a week. Yes, the castle ring, I thought that might be it but was unsure. I removed that and then I could see the three screws which were very loose. Tightened them and all good. A heap of sand and grit in there too, cleaned all that out, very much better. Yes there is a roll of film in it now. |

This one also had a non-firing shutter. I thoguht it would be the shutter itself. But while I was tooling around under the top cover cleaning the rangefinder etc I noticed this pink lever near the shutter button - its for the multiple exposure mechanism - I gave that a tweak and lo and behold the shutter fires and the wind on works again. I'll try and post a picture. |
