So i have a J9 / J10 / Vector V2, I love the J9 but was waiting for one of them to die so i could get into modding, J9 went first with a few broken springs running the 11V.
Got some BigR’s - plunger - metal ladder- Oring and 1.3 spring and some shims / stock motor and pinion.
Watched Guido until my eyes bled and pulled the box apart so many times i’ve lost count.
I thought i had shimmed it properly, gears seem to move ok but do require some force to spin once the screws are all in.
i put the handle on fire it up and it compresses all the way back and then stops, after that its just a grinding sound…
Pulled it apart again - reshimmed just incase - same thing
changed the spring back to stock - same result
I checked the beville gear is spinning so the motor is pushing it, the stock nylon stuff is all still ok so thinking of chucking that back in with the new plunger to see if its my 15th tooth grind /AOE that is the issue.
What else should i be looking at ?
learning process here, i’ll eventually get it and in no rush
