Re: 356 front crankshaft oil seal intallation

I have assembled a few Packard engines (including 22nd Series 356) with this type of seal and never used the alignment tool. Up and down adjustment is pretty much governed by the oil pan gasket mating surface, leaving only side to side movement which is also limited by the clearance between the holes in the timing cover and the attaching bolts.
This is a simple type of mechanical seal that is spring loaded to press the circular cork insert against the inner surface of the timing cover. The entire seal assembly rotates and a thin film of oil between the cork insert and timing cover provides lubrication.
