Purpose, Function
Connecting rod
The connecting rod transmits the reciprocating movement of the piston to the crankshaft by engaging the piston pin and crank pin.
Connecting rod bearing
The connecting rod bearing forms an oil film on the outer surface of the crank pin to prevent wear due to sliding.
Construction
Connecting rod
The connecting rod is installed between the piston pin and crank pin.
High-strength, forged carbon steel has been adopted for weight reduction.
A cracking method*1 for breaking off and separating the connecting rod from the connecting rod cap has been adopted for improved accuracy.
Weight has been reduced by optimizing the shape from the I shaft to the large end.
Reciprocating inertial weight, including the piston, has been reduced with the use of a full-float type for the connection with the piston and further tapering of the small end shape.
With the adoption of the plastic region tightening*2 method for the connecting rod bolt, the stability of the axial force has been improved.
*2 Plastic region tightening is a method of controlling the tightening using the rotation angle of a bolt. By tightening to the region (plastic tightening region) in which bolt deformation does not become irreversible, variation in axial force is suppressed.
Connecting rod bearing
The connecting rod bearing is installed on the outer surface of the crank pin.
The upper and lower connecting rod bearing are made of aluminum alloy.
Intermediate Shaft Removal/Installation
WARNING:
The steering column (EPS motor) temperature increases directly after continuous
turning of the steering mechanism which could cause burns if it is touched.
Before performing any servicing, verify that the steering column has cooled
off.
1. Rotate the steering wheel un ...
