What will happen with improper shimming?
And what should I do to remedy the problem?
With incorrect shimming (being too loose), at least one of your gears (the sector
gear in particular) will break within one or two rounds of hi-cap. If shimming has
been overly done (too tight), the gears will not break but your motor and your
battery will get hot quickly. You will also experience frequent lock up and will run
out of battery power very fast.
If several teeth of the sector gear go broken after 600 shots, you will need to
re-shim again in such a way that the sector gear and the spur gear can come
closer to each other. If the motor is eating up battery power like there is no
tomorrow, check the shimming on the bevel gear and the spur gear. When you
re-shim any one gear, also double check shimming on the rest.
