To all enthusiasts of the Airflow.
I am currently restoring a C9 Coupe and have discovered that the crankshafts that I have are embossed with the numbers 618624 and these numbers don't match up with the numbers listed in the master parts list for Chrysler passenger cars from 1936 to 1942 issued in July 1947. This book quotes the number for the crank as 618623.
I believe that the crank that I have was out of my fathers CV Coupe but am not sure. I also believe that it is the long stroke item at 4.875 inches.
I also have a crank which is embossed with the numbers 618620 and I believe that it is the shorter stroke version at 4.50 inches from a CU.
Further to this I am chasing the rear main oil seal for the crank on the C9 and my books tell me that it is part number 304744. It also lists the rear main seal complete with the seal retainer as part number 308354. A complete kit comes up with part number 891456. Does anyone know where I can purchase the seals as well as the information on the origin of the cranks that I have as well as confirmation on what should be in the Coupe.
Regards to all
