ID some 28-32 Engine cranks

[KRK Sr.]

I need someone with a 30's parts book who can identify which part number cranks go with what year and series Cadillac/LaSalles.Also what one fits the 8's and 12 cyl. cars. Part numbers are: 878724, 875499, 884871. they all "look" the same, but the end that goes in the engine gets about 3/4 inch longer from shortest to longest. I checked the AACA Library last spring but could not find them in a later 1940 edition of the parts book. Thanks for your help. Karl

Dear KRK Sr.,

Are you sure you have the actual PART numbers....

or do you possibly have CASTING NUMBERS ??????

They are often NOT the same.

According to a 1942 Cad Master Parts Book

that goes back into the 1930's applications:

The GROUP# for Crankshafts in this 1942 EDITION CAD PARTS manual is 8.0687

early PART Numbers (not Casting #'s)are

at first by Model Series, later by year

345BC,355BC PART NO 1081302

350 PART NO. 1096967

355D PART NO. 3500221

370 (V-12) PART NO. 1096182 AND SAME ALSO USED ON

1936 SERIES 80,85 & 1937 SERIES 65 WITH ADAPTER #1401181

You might contact Cadillac Historical Services

to see if they have a Casting # to Part # Conversion

I believe it is linked off the CLC Webpage at
