Still no one interested?
Ok, now here we go...
Completely disassembled the crankshaft:
To make the promary cover fit, I trimmed the end of the driveshaft:
Gave it a centre bore:
And cut a new thread to accept the primary sprocket nut:
As the crankshaft was already in pieces, I thought I might give it a new bronze bush, instead of the weak original one. While waiting for the material, I decided to chop off the passager peg holders:
Naturally I cleaned everything, but I have no picture of that...
When I finally got the bronze, I started by turnign the outer diametre, just a few 1/10mm larger than needed, and contunuing with the inner and a groove for the oil:
Comparing the old one against the new one:
You can see the old one is already damaged:
The new bush is pressed on the crank pin, instead of being a floating one:
Turned the bush to its final diametre, exactly the same as the old one:
Fits perfectly:
And while I was at it, I did a little job on the connecting rod as well:
And finally I reasembled the crankshaft and trued it to just ~2/100mm of runout:
Stay tuned for more...
