Guys,
I can't find the timing mark on my Mag gears for my IO540.
My extremely current Lycoming Overhaul Manual(circa 1974) claims:
7-103. Note that the magneto gears shown in figure
2-8 are marked with a circle on one tooth. This tooth
must mesh between the two circles etched on adjacent
teeth of the larger diameter gear of the crankshaft
idler gears.
Thankfully figure 2-8 shows the gear as a round circle with a dot, great for concept not so great at showing the details.
Any hints on where those marks are located?
Thanks
