Timing Gear Drive
I found it on Page 41..........This mod is used to squirt oil on the fuel pump eccentric, but as we all know the plate is behind the cam timing gear so NATURALLY it would oil the chain, sprockets, gear drive and everything else in there.
Here are some pics of page 41, it says to drill a "1/64--.016" hole in the galley plug and a bigger hole about 1/4" in the retaining plate. It has been awhile since I did this mod on the 340.
Sorry for the blurry pics but you get the idea.
