crank washer?
what was the purpose of this washer in the back of the crankshaft on my 428 ?
it came right out with a pair of needle nosed pliers with no resistance the center hole looks as though it was cut with a torch as the back side is blued around the hole...

My only guess would be that it was needed to properly space and center a aftermarket torque converter, because I have had three 428 motors and I don’t recall ever seeing that .

Maybe during that build time the union was fighting with management. The Freemont plant was famous for dropping a ball bearings in the bottom of a door to create a rattle so it will come back.
Whatever it is, looks like a bonehead move to me. What is the wear in the middle of the washer from ? |

Do you have two converters on hand?
If so can you compare the overall lengths of there snouts to each other? Maybe the factory got a bad batch of converters and had to make up those washers / spacers to use those converters. I can think of others things transmission wise that may have made for a need for a spacer also, but I will wait to post that .

Doesn't the flywheel locate the converter?

The converter centers on the input shaft splines of the transmission.

That is the centering snout off of the torque converter.

Odd crankshaft flange. In my opinion the pump bushing centers the converter. The converter snout “walks” in-out as the flex plate “flexes”.

Was there any washers/spacers between the flexplate and converter?

To me, I figure someone had a pilot bearing in there then they put automatic in. The bearing kept converter from seating correctly. After many thousands of miles all wallowed out from flexing.
