Re: Stewart's 1955 Packard 400

I got back to tearing down the engine today. Today it was timing chain and piston removal.
I was not expecting to find the pistons already numbered. So unless someone tells me that Packard numbered them during assembly I am going to assume this is not the first time my engine has been rebuilt. The pistons and cylinder walls appear to be in great condition. Will know more when I roll the block back over. I might try removing the crankshaft tomorrow and roll it.
The crankshaft itself also appears to be in good shape. So far the only part that looks like it has to be replaced is the timing chain. Perhaps the mouse fragments I found in the timing gears wore the chain out. I really wasn't sure what it was until I saw whiskers.
I was not expecting the harmonic balancer to come off with the fan belt pulley (shown below). I thought they were two pieces. There were two different pulleys of course. The first separated easily with a little prying but I kept trying to pry off the other pulley and gave up and used the gear puller instead.
