I found a NOS tach. in perfect condition for a good price.
I also received back a first pile of parts that have been corund blasted in the meantime.  The wheel hubs will now be polished to shine as new again.

Oil seal 15x24x7. In a later right side cover (71) it is 15x32x7

Smaller bearing for Transmission in both sides of the case. 15x40x9 mm. One was marked x98302 KH SRO. The other was just marked Made in Italy and something I could not read like PVR AVP. Don’t know.

The wheels are totally disassembled. I will give them out for cleaning (sand blasting) and I will probably have the hubs polished. Cylinder head and barrel will also be sand blasted.
Yes, there is a X-90 cylinder head also on this picture. 😉

double row ball bearing for crank in right engine half: 3305 FAG O.B Germany. Size: 25x62x25,4mm

I bought a cheap tool set to remove the ball bearings from the engine case (left picture). I totally regret it. It was a waste of money. The tool is from a much to soft metal and it bends while the bearing still sits tight. I now own a professional bearing puller that worked like a charm.

The engine case is open now and it looks like I did no damage. *Happy*

I will discard the wheel rims and buy new ones as re-chroming them would be more expensive and Radaelli rims are still available today. Thanks to Moto Italia I also now own a engine split tool.
