CRANKSHAFT ASSEMBLY
Crankshaft assembly for the engine bottom end, listed in the crankshaft and connecting rods parts-book figure.
70-8778 is the crankshaft assembly listed under the CRANKSHAFT AND CONNECTING RODS figure in the parts books, also shown under the earlier E8778 form. This is the rotating heart of the bottom end - the shaft the connecting rods, flywheel, and timing/drive gears all hang off of, running in the main bearings in the crankcase.

A crankshaft assembly like this one is usually supplied complete with its associated hardware as shown in the figure, rather than as a bare forging, though our catalog record doesn't spell out every piece included in this particular listing.
Our catalog record ties this part number to appearances between 1969 and 1973, but doesn't pin it to one specific model. Given that it's a major bottom-end component, get the numbers off your existing crank and check them against your parts book before ordering - crankshafts are not something you want to guess on.
