Mamiya RZ67 film not advancing - I found the problem!

Cheap & quick PCB, 3D Print, CNC machining and fabrication services: https://www.pcbway.com/ I've had my Mamiya RZ67 for quite a while now and have experienced the cocking lever skipping when advancing the film. Luckily I have 2 film backs and I know that 1 of the backs does not skip so I guess there must be something wrong with the film back and not the camera. Let's take it apart and see what we find. You can skip to 6:35 to see what was actually causing my gear skipping issues. I hope this helps fellow Mamiya RZ users. 0:00 Intro 0:27 The Issue 2:31 Troubleshooting 5:42 Finding some wear on gear 6:35 FAULT FOUND - The reason my lever was skipping 8:40 How to troubleshoot your cocking lever issue 💚 Support me 💚 Patreon -   / thisdesignedthat   --------- GEAR USED: BEST CAMERA UNDER $1K (US) https://amzn.to/2GpRCIw | (UK) https://amzn.to/2Xg7dOo FAV LOW LIGHT LENS: (US) https://amzn.to/2QT7aJ5 | (UK) https://amzn.to/2v7HbRr FAV MACRO LENS: (US) https://amzn.to/2VcOa6O | (UK) https://amzn.to/2V12pPA GOOD VLOG MIC: (US) https://amzn.to/2Sdr12I | (UK) https://amzn.to/2DfVyHU AMAZING LOW COST LIGHT: (US) https://amzn.to/2ElMJxg | (UK) https://amzn.to/2v8A23u 120CM QUICK SETUP SOFTBOX: (US) https://amzn.to/2IAOBDf | (UK) https://amzn.to/2F6jcrd
