Thanks Gadge

Trying to reassemble the engine now, having issues getting the top crank shaft bearing slotted back in (even with oil). I've slipped the extension bar over the shaft and tapped.. it goes in half way then hard to get further.
Unfortunately I dont have a press to use, so was planning on removing the bearing and just installing that first, then installing the crank.. but.. the bearing is blocked. The shaft the bearing slides on is met with a wider (mis-shaped) spacer (mis-shaped may be defect, or meant to be shaped like that?.. seen in pic)
After the space is another odd shaped end with a flat side (looks like half-moon).. but seems to be a part of the actual crank end..
Thoughts and suggestions on removing the bearing? is there a trick im not seeing ?
