any one know which way the thrust groove goes faceing the block or the crank.

 

the thrust bearing should have a face perpendicular to the crankshaft. this face should be machined flat, and also look like a bearing sureface. this face goes in the direction that it is against a matching face on the crankshaft. it SHOULD only go one way.

 

The grooves face outward, away from the block.

 

thank u so much.
