A simple tipster on how to to refurbish your Ricoh 500G. Read on to see how I did it.

Some time ago, I talked about the characteristics of this rangefinder in this article. As mentioned in that article, this machine has only one flaw: over time the seals which are almost entirely inside the loader of the door rollers, tend to get damaged.

The damage was so bad that I had to redo all the trimmings.

What you will need:

  • Alcohol
  • Cotton Swab
  • Toilet paper / towel rolls
  • Cutter
  • Riga
  • Scissors
  • Neoprene Sheet

First you must find the right insulation. After a thorough research, I chose to use a roll of 40mm thick insulation with an adhesive side from Leroy Merlin for €5.

Now the work begins!

1) Clean the entire machine of old gaskets using cotton buds (soaked in alcohol)

Use the paper towel to help remove all the residue (you’ll see the finished stage of the process at the end of the tipster.)

2) Cut Neoprene strips according to the needed size.

In the case of Ricoh 500G, here are the measurements:

A – Approximately 6.8 cm x 2.2 cm (hinge side)
B – Approximately 6.8 cm x 0.8 cm (side door)
C – about 8.65 cm x 0.5 cm (low side)
D – Approximately 8.65 cm x 2 cm (top, here is also the viewfinder)

3) Attach the new seals, stick them well to the sides of the camera.

4) Finally, close the door and press to adhere well and bring it to form. Using a rubber band also helps.

Here are the photos taken with the Ricoh 500G after cleaning it:

Obviously, I have done this work for a Ricoh 500G but you can use the idea for any camera that needs new seals.
