This photo shows a Lockwood Chief crankshaft that has been drilled for oiling the big ends of the rods. The white wire ties show the oil holes. I believe it is for a racing Chief. Ignore the threads for the flywheel nut since they should be 1/2-20 and not the 1/2-13 repaired threads shown. This keyway is also damaged wider than it should be. The number 20227AA is on the Chief cranks but not always readable. Chief keyways are occasionally cracked in the corner or stretched wider from a loose flywheel pounding it. Always remove all traces of lube/oil/dirt from the tapered flywheel hole, and key, and keyway, and the crank taper before assembly (use solvent).
