My rouine maintenance and"lets see where that leaks coming from has led me into an impromptu gearbox build. But i,m a bit miffed by this piece. [/IMG] Its the clicker wheel on the left, it has a bit of play. [/IMG] Joerg, you say to spot weld these bits together if there is any play.The wheel has a bit of play on its shaft against the circlip and a bit of play between the actual 2 wheels in the second pic .Is this normal or not? Sorry .this is my first box!
