I've finally got round to restarting some of the little jobs on this bike after a long time doing other things- and then having a cement mixer block the entrance of my garage for a few months while I built a garden wall meant I haven't done anything purposeful for ages.
Not quite true as some little things have been done, I just haven't got around to writing them on here.

Today I changed the cambelt.
This was a major pain at first, after buying a flywheel holder and faffing around trying to undo the nut I gave up.... for three months!
I eventually bought an electric impact driver and the nut came off in seconds, out came the small spring washer and the puller went in, this also needed the impact driver to get it off  but off it came.

Not a great picture, but the alternator is held on by three screws and on undoing them I discover the securing plate is broken around the right screw. I'm hoping that doesn't cause me problems later.

Then after thats off, theres a spring on the shaft,then a circlip holds in another spring and a guide plate for the belt on the bottom pulley.
The belt itself is just walked off and the new one goes one with a bit of effort, I checked the two timing marks matched and bolted it all back together.


I did notice the old belt was a size 'A' to match the engine (only a factor when the engines were new,any proper sized belt will fit now) and it had a Moto Morini logo on it. I have a suspicion that this was it's original factory fitted belt and is now over thirty years old, that said the old one looked OK.


I was expecting to have new steering head bearings by now but after holding onto the old ones for months the local shop has told me it cant get them, this was a disappointment after all that time, I'll just clean up the old ones now and put them back in soon as they are in decent condition other than some rusting and flakey chrome on the outside.
