The little part with no home

I bet you all think that I’ve been sitting back kicking my shoes off and relaxing over the Christmas period.

Not a bit of it.   I’ve been scratching my head, baffled over a couple of things that I do not know how they go back together.

I have a little tin.   In the tin are things that can loosely be described as “things that came out of the crankcase”.   I label them thus because as I was taking things out of the crankcases I was putting them into the little tin.

I ended up with these two chappies.

both have a threaded bolt that fits perfectly into the drum with the wiggly lines in it that changes the gear.  Trouble is, there is only one hole and two bolts.

Endless fiddling and trying things in different places and looking at pictures on the internet and I now know what they are.  The bit shaped like a star is called “Cam. gear shift” and the other bit is called “Stopper.Drum”.    The reason that I couldn’t work out where they go is because they are on the outside of the crankcase rather than on the inside. The star shaped bit screws into the wiggly lined drum and the stopper then nestles it’s pretty little head into the star shaped thing.   When you change gear, by some miracle yet to be discovered, the stopper makes the star turn round and thus the gears change.  Simple when you know how!

I’m still very stuck though.   I have the kick start assembly all ready to go in.  I see where it goes and I see that it has some cogs that mesh into the gearbox.  What I don’t see is why bits of the kick start seem to rub against bits of the gearbox and I also can’t see what stops the kick start bits flying randomly around the engine as soon as everything is running.  I am totally baffled by it.   I think perhaps my only hope is to take apart another engine to see exactly how things go back together again.   I fear that this will lead to another bunch of cogs on the floor and another scratching of my head.  If there is anybody out there who has any knowledge of these at all then please drop me a line and give me some advice.

Other than that, once I’ve worked out how these bits go back together it is just a case of reassembling the engine.   It should be fairly easy to do!

Happy new year everyone.  We should be back to normal service now I no longer have to spend every weekend shopping for Christmas presents.
