I've rebuilt several M,SM,400 engines over
the years, but on my first C153 from a 504.
I did the usual: crank and piston rods to
the machine shop etc. I bought the
appropriate main and rod bearings per the
machinest. Here's the question. With the
notches in their slots, on the cap, the
bearing is flush on one side, protruding on
the other. On the rod, with the notched
side flush, the apposing side is recessed.
Kind of a male female situation. When
bolted together, it closes up nicely. No
gaps, no drag. Every other engine I've ever
done, the inserts were flush on each side.
Anyone else ever seen this? (Couldn't get a
shot of the rod)
