YAY!!!

I took the engine - with pulley attached over to a mate's place - he's got one of the best setups you'll ever see - plus a wealth of knowledge and experience.

We considered all the responses I've had and ended up assuming the pulley was just slid on to the original JAP crank. So we ended up hammering (and hammering....and hammering) a couple of chisels down in between the pulley and the crank case and got not movement

Applied some heat - heard a bit of a "crack" - more hammering and it began to move ever so slightly.

Of course once is started moving it wasn't so tough to get off.

Then it was easy to get the valve gear, the valves and the crank out - the bearing was a little difficult, but came out eventually.

Cleaned everything in my mates 53 litre Ultrasonic Cleaner!!

And now this is where I'm at.....completely apart.









The bore looks OK - but I'll give it a hone anyway - new rings and new bearings - new gaskets - and the carby is going to need some sorting out I'm sure - hopefully I can get a carby kit for it.

But as for now - bead blasting for the cowl and crankcase and start the prep for painting.

I've uncovered quite a few spots of the original paint colour - a kind of pale/steel blue - a metallic shade - I am thinking of doing it with GALMET Hammer Finish Reef Blue - seems a reasonably close match to the original - but how will it handle the heat?

I will probably do the crank case and cowl the Hammer Finish Reef Blue, but the barrel heat proof matt/satin black and leave the head polished alloy.

Now - just to get it done.

Very happy!!!
