COMPONENT PARTS
Never set the connecting rod with its fracture-split surface (unmachined surface) facing downward.
Also never allow it to contact with the split-fracture surface for preventing scratches.
• Angle tightening is used for the connecting rod tightening method for ensuring even and stable tightening
axial force.
SPECIFICATION
Cylinder Block
INFOID:0000000012197359
• An aluminum die-cast half-skirt block with mirror bore coating is
used.
• The water channel on the cylinder block left side is integrated with
the block to allow a more compact engine.
• The insides of the cylinder bores are coated with a thin iron film
and the cylinder liners are eliminated for reducing weight and
improving cooling performance.
• The centers of the cylinder and crankshaft are offset for reducing
friction.
• A shallower water jacket (shallower base) is used around the cylin-
der bore to reduce heat loss to the coolant and maintain an even
liner temperature.
• Projecting shapes are used on the cylinder liner periphery for improving aluminum adhesion for reducing
bore deformation and improving cooling performance by increasing the surface area.

Front Oil Seal
INFOID:0000000012197360
A structure is used in which the front oil seal is applied to the front
cover.
Rear Oil Seal
INFOID:0000000012197361
A structure is used in which the rear oil seal is applied directly between the cylinder block and oil pan (upper).
Oil Pan
INFOID:0000000012197362
• A split oil pan combining a die-cast aluminum pan and sheet metal
pan is used.
• An oil gallery is provided on the oil pan (upper), and the oil filter is
mounted directly.
Engine Mount
INFOID:0000000012197363
• A type with three supporting mounts (left, right, rear) is used.
• Aluminum brackets are used for the right and left engine mounts to reduce weight, improve rigidity, and
improve quietness.
• A fluid mount insulator is used for the right engine mount, and a rubber mount insulator is used for the left
engine mount.
• A torque rod type is used for the rear engine mount to restrict engine movement.
