CRANKSHAFT ASSEMBLY
Crankshaft assembly for the engine bottom end, cataloged for 1973-1974.
71-3307 is a crankshaft assembly, the rotating heart of the engine's bottom end that carries the connecting rods and translates piston movement into rotary power. It shows up in the crankshaft and connecting rod sections of the parts books, alongside the cylinder block and piston listings, which tells you this is a complete assembly rather than a single machined piece sold on its own.

Our catalog record only ties this one to the 1973-1974 window, so we can't say more about which specific model or engine size it was fitted to. If you're matching this to a bottom end you're rebuilding, give us a call with your frame and engine numbers and we'll confirm before you order.
A crankshaft assembly like this is not something you swap on a whim - it's tied closely to the flywheel, main bearings, and connecting rods it was balanced with, so fitment accuracy matters more here than on most parts.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
