Fruit Machine Chat

I have a promblem with a pusher called Jive Money in the fact that the pusher dont go all the way back or all the way forward, in just jerks forward and a back a fraction, looked for coins blocked, cant see any. dont know anything much about pusher as this is the first one i have ever worked on. and there's no book inside machine to give any help

Any help would be great.

i'm afraid your going to have to strip the whole thing down 2 have a look. prob loose coins jamming it somewhere

What parts down I need to strip down. i enclosed a pic of the machine.

everything will unscrew, just basic tools. just remember where everything goes for re-building it
