SV06 Extruder Gear common issue, repair, and maintenance guide

The pinch screw, set screw on extruder gear set was found loose over time and cause gear grinding. In fact, this is number one killer for this extruder design so far. One guess is that the pinch screw was never tighten since they assembled. The unit on video total running hours is less 30, so...I was lucky enough to discover that. But many others have ended up with completely bad gear.
This was found on day 1 after they released this extruder design. Many months later, I don't know why they still have not fixed it. Operator error on the shop floor? Maybe, but there should be a way to eliminate human error on this one. It is just so hard to not get it done right.
Many people may disagree that you should not put threadlock on this tiny pinch screw. CUZ you will never be able to remove it again. But, there are cases that it got loosen again over time after people tighten it. Since the spur screw it located at encounter fast speed rotation and vibration. But you decide whether to put threadlock or not.

There are many disassembly and parts involved, I thought it would be helpful if there is a video could help beginners.

Thank you for this. I recently had my first clog on the SV06. I decided to take things one step further than simply declogging it, and do some maintenance and learn how the tool head works. This video was very helpful and I am back up and running with more knowledge than I had before.

Hey, thank you so much for your videos and the effort you put into them - I really enjoy your whole channel!!
I have a Sovol SV06 and have massive problems with clogging/heat creep. I have tried replacing the heat break cooling fan for a stronger one, optimizing retract settings and also reapplying thermal paste to the heat break. I wonder if some else has similar problems or any tipps how to solve the issue

Thanks for video. Done that with your help 😊 Mine wasn't loosent but had a ton of black dirt... I cleaned everything up and added thread locker to prevent it.

The low strength purple threadlocker should be removable.
