Section VII. LUBRICATION SYSTEM
59. Description
A gear type pump supplies oil to four noz-
zles which direct oil streams against fins on the
connecting-rod caps. Part of the oil enters the
rod bearing through holes in the rods, and the
balance of the oil forms a spray or mist which
lubricates the cylinders and all other parts of
the engine.

upper left side of the flywheel shroud. A por-
tion of the lubricating oil entering the governor

pended solids are removed.
