LUBRICATION
Both EH30V (EH34V) and EH43V have a trochoid pump inside the main bearing cover that is
driven by the camshaft.
EH3OV and EH34V use forced splash
type
lubrication while the larger EH43V employs a pressurized
-lubrication which pressure lubricates all the rotating surfaces of the crankshaft and supplies
oil to piston, cylinder and connecting rod’s small end from the oil jet on crankshaft arm.
