OPERATION PROCEDURE

  1. Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged.
  2. Use the Intelligent Key or mechanical key to turn the ignition switch to the "ACC" position. At this time, the steering lock will be released.
  3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
  4. Perform the necessary repair operation.
  5. When the repair work is completed, return the ignition switch to the "LOCK" position before connecting the battery cables. (At this time, the steering lock mechanism will engage.)
  6. Perform a self-diagnosis check of all control units using CONSULT-III.

DESCRIPTION

Selection pointsSelection partsSelection itemsSelection methods
Between cylinder block and crankshaftMain bearingMain bearing grade (bearing thickness)Determined by match of cylinder block bearing housing grade (inner diameter of housing) and crankshaft journal grade (outer diameter of journal)
Between crankshaft and connecting rodConnecting rod bearingConnecting rod bearing grade (bearing thickness)Combining service grades for connecting rod big end diameter and crankshaft pin outer diameter determine connecting rod bearing selection.
Between cylinder block and pistonPiston and piston pin assembly (piston is available together with piston pin as an assembly.)Piston grade (piston outer diameter)Piston grade = cylinder bore grade (inner diameter of bore)

PISTON AND BEARING Specifications

  1. The identification grade stamped on each part is the grade for the dimension measured in new condition. This grade cannot apply to reused parts.
  2. For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
  3. For details of the measurement method of each part, the reuse standards and the selection method of the selective fitting parts, refer to the text.

Scheme 5

Scheme 5: When New Cylinder Block is Used
  1. Check the cylinder bore grade on rear left side of cylinder block (L), and select piston of the same grade.
  2. If there is a correction stamp mark on the cylinder block, use it as a correct reference.

Scheme 6

Scheme 6: When Cylinder Block is Reused
  1. Measure the cylinder bore inner diameter. Refer to " «CYLINDER BORE INNER DIAMETER»(ref-337614-S04578441132009080600000) ".
  2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner diameter of the "Piston Selection Table".
  3. Select piston of the same grade.
