Piston, Connecting Rod, and Bearing Cleaning and Inspection Measuring Device Method
Special Tools
EN-45059 Torque Angle Sensor Kit
- Install the inner plunger and calibrate with the micrometer gauge (1).
- Mount the connecting rod bearing cover on the connecting rod.
Caution: Refer to Fastener Caution in the Preface section.
- Tighten the 2 bolts in three passes using the
EN-45059 sensor kit
:
3.1. | First pass tighten to
35 N·m (26 lb ft). |
3.2. | Second pass tighten to an additonal
45° degrees. |
3.3. | Third pass tighten to an additional
15° degrees. |
- Measure the connecting rod bearing diameters at 3 points.
Measure at points A, B and C with the internal measuring device.
- Work out the average connecting rod diameter.
Formula: A+ B+ C /3.
- Measure the connecting rod bearing journal diameter at 2 points.
Measure at points A and B with the micrometer gauge.
- Work out the average connecting rod bearing journal diameter.
Formula: A + B/2.
- Determine the connecting rod bearing play.
Calculation formula: average connecting rod bearing diameter - average connecting rod bearing journal diameter.
- Perform the target/actual comparison.
Permissible connecting rod bearing play: 0.019-0.071 mm (0.007-0.0028 in).
Piston, Connecting Rod, and Bearing Cleaning and Inspection Plastigage Method
Special Tools
EN-45059 Torque Angle Sensor Kit
- Remove the oil pan. Refer to
Oil Pan Removal.
- Remove the connecting rod bearing cap.
2.1. | Mark the installation position (1) of the connecting rod bearing cap. |
2.3. | Degrease the connecting rod bearing cap and wet the connecting rod bearing clip with engine oil. |
Note: Do not rotate the crankshaft.
- Lay on plastigage. Refer to
Adhesives, Fluids, Lubricants, and Sealers for the recommended plastigage.
Lay plastigage (flexible plastic thread) over the entire width of the connecting rod bearing journal.
- Install the connecting rod bearing cap.
Caution: Refer to Fastener Caution in the Preface section.
- Tighten the 2 bolts in three passes using the
EN-45059 sensor kit
:
5.1. | First pass tighten to
35 N·m (26 lb ft). |
5.2. | Second pass tighten to an additional
45° degrees. |
5.3. | Third pass tighten to an additional
15° degrees. |
- Remove the connecting rod bearing cap.
Remove the 2 bolts.
Note: When reading the value, do not confuse millimeters and inches on the measuring scale.
- Measure the connecting rod bearing play.
• | Compare the width of the flattened plastic thread with the measuring scale. |
• | Permissible connecting rod bearing play: 0.019-0.071 mm (0.0007-0.0028 in). |
Note: Check markings on parts.
- Install the connecting rod bearing cap.
• | Wet the connecting rod bearing journal and con-rod bearing clips with engine oil. |
- Tighten the 2 bolts in three passes using the
EN-45059 sensor kit
:
9.1. | First pass tighten to
35 N·m (26 lb ft). |
9.2. | Second pass tighten to an additional
45° degrees. |
9.3. | Third pass tighten to an additional
15° degrees. |
- Install the oil pan. Refer to
Oil Pan Installation.
