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.
