1929 Crankshaft Flange


Recommended Posts

Hi all DeSoto fans,

Information required. 

Need to replace the rear seal on the crankshaft. So far I have removed the flywheel. Now the flange will have to come off to give me access to the seal cover.  My question is: How is the flange secured to the crankshaft?    Any hints will be gratefully  received. 


Cheers, and happy motoring......

Hi Thor

I have a 1930 DeSoto, and I also have a 1929 owners manual. From my memory the rear flange is part of the crankshaft. I believe that you have to remove the oil pan, then remove the rear bearing cap and feed a new wick seal into the groove.

Good Afternoon Rick,

Thank you for your feedback. You are quite correct, I did some deeper research yesterday and found the flange is part of the crankshaft. I did remove the flywheel to gain access to the seal cover - two parts. Fiddly job, but worth it to eliminate the annoying oil leak.
