Replacing the Master Removal Belts on a Riso RP-3700

I recently went to the hospital after experiencing another seizure and took the following week off to recover a bit. The entire ordeal has been intense both physically and mentally. I felt like I ran an entire marathon and nothing smelled or tasted the same way as I remembered before my seizure. It’s bizarre and emotionally draining.

I had to take a week off of work and stay home, so I decided to start working on the repair issues I had on my Riso RP 3700. I’m obsessed with finding broken equipment and fixing it. My garage is FULL of guitar amps which I have found and fixed. I’ll post about that later.  I found this duplicator and brought it home to start making fun prints but immediately began having master disposal errors and jams any time there was more than two masters in the disposal tray.  After reading around on forums I found the right parts and bought the new belts and followed the guide on stencil.wiki. I asked the wonderful people on the Riso FB group for some tips and after two hours of slow and cautious work, I was done!

I purchased a pair of circlip pliers from Harbor Freight and let me tell you, it made the job a hell of a lot easier than using a small screw driver. No flying circlips, no lost parts.

After I put it all back together, I made a test master and it worked! No jamming master sheets.
