Taking Apart the Crank Assembly

I'm going to use a new crankshaft and new connecting rods for the rebuild, so I don't need to take the rods off of the old crank, but I'm curious about what the bearings look like.

First step is to remove the nuts:

Then the rods just pull away from the "caps":

All four are off and their bearings lined up:

Here's a close-up of the bearings to see the wear. Compared to the main bearings, these show a lot more wear, but I don't think it's serious or anything to be concerned about.

Next I pull the fan hub with a puller (this will be reused on the new crank):

And the distributor and cam drive gears will also have to be moved over to the new crank.

I now declare the engine officially apart! The flywheel is off at the machine shop getting resurfaced, and the cylinders are getting cleaned up to be reused with the new pistons.

After the crank, rods and pistons show up, those will be sent out with the flywheel and blower fan to be balanced.

Soon the heads will go off to be rebuilt, ported, polished and flow matched.

Then it'll be time to "assemble in reverse order" - and it'll be done!
