I am reassembling a 1990 40 hp Evinrude and I am stuck. The disassembly was done by a shop a year ago. Everything went smooth until I tried to line the crankshaft bearings up with the alignment pins. The center bearing lines up and the bottom bearing, no pin, lines up. The top bearing holes are about an inch from lining up. It appears the bearing is to large and since I did not do the disassembly I really need some help here! I have attached pictures. Pic 1 shows the the alingnment when on the crank - note the bearing hole and the portion of the bearing that extends toward the flywheel. Picture two shows the bearing without the crankshaft. The bearings lays in nice and lines up flush with the block. Anyone know what is going on here?

Picture 3 - An overview of the block with the crankshaft in place. Top bearing does not line up - middle and bottom Bearings line up fine. Top bearing is off by about 1" but the rest of the crankshaft can not move 1". httpwwwflickrcomphotos30642913N00191765686 this the wrong top bearing?

Flip the bearing over. Its on upside down.
There is also a rubber o-ring that goes on it and fits in that groove in the block.

Thanks Walker - The fact that the bearing fits flush without the crankshaft had me worried. I flipped the bearing and it lines up now. Thank you very much for your help - cant wait to get this thing running.
