Very similar to the previous forum but
there are some subtle differences

Block was deburred before painting.  Now we are radiusing and deburring the main caps.

Spuddyboy

Eagle Crank had metal burrs left from balancing.  These need to be removed or they will break off in the engine.

Spuddyboy

This is what it looks like after deburring.

You can't clean things too much after grinding.

Putting in the main bearings.

The middle bearing (#3) is the thrust bearing.  

Spuddyboy

More OSHA approved footwear!   :o

Spuddyboy

Main bearings were installed.  Main bearing caps were torqued to spec.  Main bearing diameter was checked with a bore gauge.

Spuddyboy

Crankshaft journal diameters were measured and clearance calculated.  Crank was placed in block.  We will doublecheck clearances with Plastigauge.  

Spuddyboy

Thrust clearance was checked also.  A crowbar helps a lot!   8-)

Spuddyboy

After clearances checked out, we pulled the crank and lubed bearings with assembly lube.

Spuddyboy

We lubed and installed main caps and installed the rear seal at this time too.

Next we dry fit the main girdle and oil pump to see if it all cleared.

The oil pump was hitting the main bolt. We ground the oil pump to clear.

Spuddyboy

Oil pickup also had to be notched to clear the windage tray.  Windage tray installed on top of main girdle.

Gapping Piston Rings is next.

Obviously we had a little work to do.   ;)

We used a Squaring Tool and a Ring File from Summit.
