Because the crankshaft was grinded it needed new undersize bearings. 0.010" (0.254 mm).
Before I replaced the crankshaft I cleaned and then checked all the oilways; cleaning with compressed air and checking by simply injecting some oil in each oilway and see were it goes. The engine block was upside down on the engine stand when doing this.

After checking the oilways I wiped the seats clean and removed all the protective grease from the bearing shells. Then I placed the shells on the seats and put some assembly lube on them. Now I could place the grinded crankshaft on top of them. But the pilot (no. 5) shell bearing was to big/wide for the grinded crankshaft......%$$#N$. I brought it back to the shop together with the new undersize bearings so they could grind the sides of the crankshaft. Btw:
Never shave the shell bearing to make it fit!

A couple of days later I could finally tighten the nuts with the torque wrench (122 N/m)
Next step is fitting the pistons.
