Looking to purchase or trade Continental O-470 K or L or M or U crankshaft. Part numbers 633219 or 643911. Or trade a Continental O 470 R and cash for crankshaft listed above.

Not sure the part number offhand, but any chance it’s the same as a IO470F or IO470VO crank.?

I have one I removed from an engine, had it magnafluxed, checked out good. I didn’t have it ground but I think I remember that it was going to end up .010” under.

Going Pponk?

How's the rest of your core? I only ask because a friend has a complete running when removed K or L motor. He removed it to install a Pponk that he had built on a 520 Core. I can fwd you his contact info if you'd like, he's not a forum guy...

The part number is different for the IO470F (630927) and I need part number 633219 or 643911. I will check with the engine re builder to see if he can use a IO470F or IO470VO crank

Yes I am going with the Pponk conversion. Purchased and installed the 3 blade Hartzell propeller 3 years ago when the old propeller needed servicing. My core is in good condition. Hoping to find a correct crankshaft but may have to purchase a whole core to get the correct crankshaft. Do you know how much he wants for the O470K core?

Try Dustin at Lawson Aviation. I know they had some cranks in stock when my motor was built - (269) 858-5756.

They would be a good shop to build the p-ponk if you don't already have a place picked out. They built mine. They stand behind there work.

Dustin at Lawson Aviation is who I picked out to do the p-ponk conversion. He doesn't have any cranks in stock at the moment. Hope he gets some in. In the mean time I thought it maybe a good idea to look for a crank. When did they do your engine?

Ok. great. you will be happy you chose them. They built my motor about two years ago. They are always willing to help after the sale.

One more very satisfied Lawson customer here! Strong engine and excellent support.
