Crankshaft End Play, Check
Note : Crankshaft attached with crankshaft bearing caps.
- Install the
GE-571-B dial gauge
.
• | Install in the holder on the front of the engine block. |
• | Place the dial gauge plunger against the crankshaft and adjust. |
- Measure the longitudinal play of the crankshaft.
• | Move the crankshaft in the longitudinal direction. |
• | Permissible crankshaft end play: 0.100-0.202 mm (0.0039-0.0080 in) |
- Remove the
GE-571-B dial gauge
.
Crankshaft Out-of-Round, Check
Note: Crankshaft removed.
- Insert the crankshaft in the engine block.
- Install the
GE-571-B dial gauge
.
2.1. | Attach to the bracket on the engine block. |
2.2. | Place the dial gauge plunger against the crankshaft bearing journal and adjust. |
- Check the rotational play of the crankshaft.
• | Turn the crankshaft evenly. |
• | Maximum permissible rotational play: 0.03 mm (0.118 in). |
- Remove the
GE-571-B dial gauge
.
Check Crankshaft Bearing Clearance (With Plastigage)
Note:
• | Do not rotate the crankshaft. |
- Lay on Plastigage. Refer to
Adhesives, Fluids, Lubricants, and Sealers for the recommended plastigage.
Lay out Plastigage (flexible plastic thread) around the entire width of the con-rod bearing journal (arrow).
Caution: Refer to Fastener Caution in the Preface section.
Note:
• | Note the correct tightening sequence. |
• | The bolts can be reused for checking the crankshaft bearing play. |
- Install the crankshaft bearing cap. Tighten the 2 crankshaft bearing cap bolts in 3 passes. Use the
EN-45059 torque angle sensor kit
:
• | First pass to
50 N·m (37 lb ft) |
• | Second pass to
45 degrees |
• | Third pass to
15 degrees |
- Remove the 2 crankshaft bearing cap bolts.
Note: When reading the value, do not confuse millimeters and inches on the measuring scale.
- Measure the crankshaft bearing play.
• | Compare the width of the flattened plastic thread (arrow) to the measuring scale. |
• | Permissible crankshaft bearing play: 0.005-0.059 mm (0.0002-0.0023 in). |
Check Crankshaft Bearing Clearance (With Micrometer Gauge Internal Measuring Device)
Note:
• | Note the correct tightening sequence. |
• | The bolts can be reused for checking the crankshaft bearing play. |
- Install the crankshaft bearing cap with the crankshaft bearing clips to the cylinder block.
Tighten the 2 crankshaft bearing cap bolts in 3 passes. Use the
EN-45059 torque angle sensor
kit
:
1.1. | First pass to
50 N·m (37 lb ft) |
1.2. | Second pass to
45 degrees |
1.3. | Third pass to
15 degrees |
- Install the inner plunger and calibrate with the micrometer gauge (1).
- Measure the crankshaft bearing diameter at 3 points.
Measure at points A, B and C with the internal measuring device.
Calculate the average crankshaft bearing diameter.
Formula: A + B + C /3.
- Measure the crankshaft bearing journal diameter at 2 points.
Measure at points I and II with the micrometer gauge.
- Calculate the average crankshaft bearing journal diameter.
Formula: I + II/2.
- Determine the crankshaft bearing play.
Calculation formula: average crankshaft bearing diameter minus average crankshaft bearing journal diameter.
- Nominal-Actual comparison.
Permissible crankshaft bearing play: 0.005-0.059 mm (0.0002-0.0023 in).
