Hi guys,

I have some problem with my spur and sector gear jamming when I am turning them by hand freely in the shimming process (to see if it all spins freely). The thing is that it blocks at one point during the rotation and I have to use some force to pass that section so that it can continue to spin freely.

Obviously I have a problem, but I really doubt that it is related to the shimming process cauz I tried all kinds of combinations.

My gun is a CYMA AK 105. So far I have almost changed everything stock for modify parts. All except the gears and the piston plus the cylinder. The funny thing is that it was working like a charm and silently right before I started changing the parts.

I am wondering if the nylon bushings are not there for are reason. They are there because that the tolerence of the 2 receiver is really bad and that the bushing holes maybe do not aligned perfectly. So with nylong bushings the nylon can be deformed slightly and compensate for that, but when you upgrade for steel bushing you have a problem. I even had to do a really minor filing job because some of the holes where a bit too tight for the steel bushing (with nylon bushing since it can be squeezed a bit that was not a problem for them to put them in the receiver)

So since with steel bushings the holes does not align perfectly and it can cause a problem with the gears.

Either that or I have crappy gears that are not dented properly are not entirely flat and they kind of wobble when I turn then and it jams at some point.

What do you guys think is the problem?
