Hello guys! Now I´m working on assembling the motor. Crankshaft is restored. After assembling left and right housing sides there was no more space between crankshaft and left housing side, not able to turn the crankshaft. Again disassambled the housing and used the shim (0,3 mm) for which the service manual says "Put shim on right side of the crankshaft, and install the crankshaft into left case half". Now I have the shim between the left housing side and the crankshaft (and removed the ridge, see red arrow on the foto) and everything is fine (approx. 0,7 mm space between left housing side and crankshaft).

Before I install the right housing side again I want to ask for your opinion because my assembling sequence is not the same as in the service manual.
