Hi, below are pictures of my machine head, i dont have a great camera so it may be easier to describe the problem.
Basically i am having problems with the stock machine head on my Fender BG-29.
The pole (?) that the tuner is on which goes through the part attached to the headstock goes through too far on my E string tuner. (this can be seen in photo 1). This has caused the 2 washers, 1 black and 1 white, to be pushed on top of each other instead of side by side as they are on the other machine heads. (this can be seen in the second photo).
I am not sure of the cause but i have also noticed that the peg holding the E string in the bridge is sticking out and no matter how many times i try to restring the E string it will not push in all the way.
I recently changed the strings on this bass for the first time since i got it (2 years ago).

I recently got a set up on the instrument, i know for a fact that the peg sticking out of the bridge is due to something they have done on the set up (maybe a change in gauge of E string?).
I think that the machine head problems i am having are also connected to the set up but i cannot be sure because they may have been there before the set up and gone un-noticed.
Any help appreciated.
Thanks
