Default assembly

Not unlike our getting ready for a run at riviting a surface, all the parts get set our on a bench ready to install.

Default Pistons

All pistons are the same weight.




Using piston pin & plug assemblies.. plugs are pressed into the pins eliminates plug wobble that sometimes fails on stock lycoming floating plugs

Default Gear terrain

A view of the accessory case. Yes there is an idler gear for the mag missing. I run dual elec ignition and they are not needed. Saves weight.

It would be interesting to see how they deal with the movable weights for the spin balance.

Question

Why is the yellow type around the lower part of the cylinders only?

Actually this is an incorrect statement. The reason for the dowels are to bring those holes back up to size, not to prevent leaks. Actually adding a second path around the bushing increases the likelihood of a leak since now there are two paths for the oil to travel. They don't do that to make them stop leaking there. The o-ring counterbore mod is done to prevent leaks.

On the 540 there is an oversize thru bolt available so its just as good to ream the holes to .002 undersize for the larger thru bolt, and then you can counterbore for the o-ring.

So unless one could not ream to fit to size for an oversize thrubolt, I would not do this mod.
