Hi BB,

Really appreciate the response, and thanks for the welcome cool

Yes, it has been a little heavier to start ha!, but I'm glad I haven't been doing any further damage **phew**!

I just went out to the shed and took a couple more pics, and one of them is on the thrust pad side (sorry, the picture is with the motor off). The shaft has a few knocks in it and wobbles against that rubber housing to the chain drive, and as you will notice, no thrust pad frown

Just to clarify (sorry, not as mechanical as I'd like to be), I can't actually get the clutch assembly off the motor shaft. I assumed it was because of the cotter pin not down far enough, but maybe it is and the clutch assembly is "stuck"?

Just inserted a couple of photos of the chain drive, which to me looks in need of love - but only you gurus could tell me for sure.
