Brief Description: Received New Camshaft

Took shipment of the new camshaft. New tach shaft Tagged fuel pump rod Update: I received a number of emails asking why there are only 6 cam lobes. Lycoming 4 cylinder engines have 6 lobes. The 4 exhaust valves are driven from their individual cam lobes... The intake valves share cam lobes as follows: Cylinders #1 & #2 share the same lobe and #3 & #4 share another lobe. This arrangement results in only 6 total cam lobes being necessary. I hope this helps...
