LUBRICATION SYSTEM
Front Cover Oil Flow
• Oil flows from the lower crankcase to the
oil pump through a passage in the back of
the front cover. When the crankshaft turns
the oil pump, oil pulled from the oil pan is
pushed from a passage in the front cover
to the vertical passage in the crankcase
that takes oil to the oil cooler cover. Two
dowels in the front cover ensure the oil
pump is concentric with the crankshaft.
• All of the passages from the front cover to
the crankcase are sealed with a silicon-in-
metal, one-piece gasket.

• The VT 275 uses a two-piece oil pan. The
upper oil pan is cast aluminum and serves
to adapt the lower sheet metal pan to the
crankcase. The upper pan also serves as a
baffle to keep oil in the pan away from the
crankshaft.
