Got my big order from Airpower today...all the little gaskets and stuff. Today's lesson is: check the parts carefully. I ordered an oil filter adapter gasket, which should be a round rubber ring. I got a bag with the correct part number on it containing what appears to be a valve cover gasket. The part number stamped on the gasket itself is completely different from that on the bag.

That's not a huge deal, mistakes happen, but this one is more interesting...
The set screw is supposed to be an AN565B1032H5. That breaks down like this:
AN565-military designation for a setscrew
B-conical point
1032-10/32"
H5-length 5/16"
What was in the bag, which according to the 8130 came from Mother Lycoming herself, is an AN565
D1032H5. It's a cupped point, not a conical point, and would barely engage the hole in the idler shaft, if at all. Both the bag and 8130 label it as a "B" conical point. $5.31, BTW:

Glad I'm figuring this stuff out now, so they aren't show stoppers during assembly.
