Hi Everyone!
Just thought I would document my rc motor disassemble, due to bad "cracking" sounds, and show how I managed to take it apart with minimal damage as possible.
I thought it was due to lack of grease inside, but this turned out not to be true. It was in fact a loose gear on its pin, as you can see below.
It was extremely difficult to take apart and a lot of force was required!! and at this stage i have no idea if it will go back together nicely and still work at all.
Seeing the condition that it is in, and the sound it makes from this loose gear, I would recommend if anyone else hears the same thing to just put up with it! haha
Any ideas on how to fix this would be greatly appreciated, as it will only get worst with time. I have considered filling it with heavy grease, or make a very thin metal sleeve for the gear.
This was a brand new motor purchased from BL.
