My engine repair

[Andreas13]

I took it apart again and tried without the seal on the right side and it turns very easily, but once again with the seal installed it's little harder to turn the crankshaft.

"Little harder" isn`t a problem...

Do this two woodruff keys sitt correctly?

Also when I took apart the motor neither of those two where there, don't know why, didn't find any loose in the motor either

They sit good.
Maybe one of the losts sits inside the magneto wheel?
The other one at the small gear must have been there, or the gear turns loose.

On the right side there are only this two woodruff keys. The third one fixes the flywheel at the crankshaft in ignition position on left side.

I never read the term woodruff key before.

Only the differential left.

What do you use to clean the gasket surface?

My grandpa was used to say Woodruff-Keil. He studied engineering before World War 2 and learned this name.
Some years later, the name changed in Germany from Woodruff-Keil to Scheibenfeder. My grandpa told me this story, during we did together an engine repair of his mower, when I was a little boy.
Meanwhile I know, it was William N. Woodruff (also Wilhelm N. Waldmeister ), who invented it. That’s the reason, why a piece of steel is named like the herbal plant we call Waldmeister. I like this funny wording.

What we call Passfeder in German is called parallel key in American English. Maybe also in British English, but I don’t really know. My technical English skills are based on doing business with US companies.

Sorry for running off topic.

But I like this old Woodruff-Keil story, because it was the best time in my childhood, sitting in grandpas garage to watching and helping him. These hours left a lasting mark on me and my life.

The by PIAGGIO used semi-dlear liquid-gasket hardened up and is extemly resistnat and thin. i remember, that i find no other way to remove mechanically.
