Oil Sump
The oil sump consists of two parts. The upper section of the oil sump is made from cast
aluminum and is sealed to the crankcase with a rubber-coated sheet steel gasket. This
section of the oil sump has a cross shaped cut out oil filter element recess. The upper sec-
tion of the oil sump is inter connected to the oil pump and is sealed with a sealing ring. The
double panel (noise insulation) lower section of the oil sump is flanged to the upper section
of the oil sump.
Crankcase
The crankcase has a one-piece “open deck” design and is made entirely from AluSil. The
cylinder walls are hardened using a specific procedure (exposure honing). Exposure hon-
ing involves treating the cylinders with a special “soft stripping”. This removes the aluminum
from the cylinder surface and the hard silicone particles remain.
