Pistons

On the left side you can see the piston that came with my replacement cylinder. It looks good on the first look, but if you look closer there is no doubt a butcher worked on it. Now I have a usable replacement cylinder but no piston for it.

Oil seals

I have removed all parts from the right side engine cover so I can send it out for polishing. The cylinder head need cleaning as well. The oil seal for the clutch basket is a42x56x7 the ball bearing for the advance is a 6203 and the oil seal a uncommon size of 17x32x5.

Removing clutch shell

High precision, fine german engineering for a special tool 😉 to open the inner clutch hub nut.
By the way as I have a 74 SS-350 this is the improved alloy clutch hub which was introduced on late 73 models. It can be identified by the higher number of toothes compared to the earlier steel hub. The late version also needs different clutch plates.

Clutch tool

Jürgen send me his self made tool for removing the clutch hub. Together with a power wrench I was able to get the center nut lose and to remove the clutch hub. The surprise followed instantly, as for the nut of the clutch shell I need a kind of spanner tool.
