Crankshaft End Play, Check
|
|
1.
|
|
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.
|
|
2.
|
Measure the longitudinal play of the crankshaft.
|
|
|
•
|
Move the crankshaft in the longitudinal direction.
|
|
|
•
|
Permissible crankshaft end play: 0.092-0.24 mm (0.0036-0.0094 in)
|
|
3.
|
Remove the
GE-571-B
dial gauge.
|
|
Crankshaft Out-of-Round, Check
|
|
1.
|
Insert the crankshaft in the engine block.
|
|
2.
|
Install the
GE-571-B
dial gauge.
|
|
|
•
|
Attach to the bracket on the engine block.
|
|
|
•
|
Place the dial gauge plunger against the crankshaft bearing journal and adjust.
|
|
3.
|
Check the rotational play of the crankshaft.
|
|
|
•
|
Turn the crankshaft evenly.
|
|
|
•
|
Maximum permissible rotational play: 0.03 mm (0.0011 in).
|
|
4.
|
Remove the
GE-571-B
dial gauge.
|
|
Check Crankshaft Bearing Clearance (With Plastigage)
|
|
1.
|
|
Note
|
|
•
|
Crankshaft removed.
|
|
•
|
Do not rotate the crankshaft.
|
Lay on plastigage Refer to
Adhesives, Fluids, Lubricants, and Sealers
or the recommended plastigage.
Lay out Plastigage (flexible plastic thread) around the entire width of the con-rod bearing journal (arrow).
|
|
2.
|
Refer to
Fastener Caution
.
|
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
sensor kit:
|
|
|
•
|
First pass in sequence to
50 Nm (37 lb ft)
|
|
|
•
|
Second pass to
45 degrees
|
|
|
•
|
Third pass to
15 degrees
|
|
3.
|
Remove the 2 crankshaft bearing cap bolts.
|
|
4.
|
|
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)
|
|
1.
|
|
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
sensor kit:
|
|
|
•
|
First pass in sequence to
50 Nm (37 lb ft)
|
|
|
•
|
Second pass to
45 degrees
|
|
|
•
|
Third pass to
15 degrees
|
|
2.
|
Install the inner plunger and calibrate with the micrometer gauge (1).
|
|
3.
|
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.
|
|
4.
|
Measure the crankshaft bearing journal diameter at 2 points.
Measure at points I and II with the micrometer gauge.
|
|
5.
|
Calculate the average crankshaft bearing journal diameter.
Formula: I + II/2.
|
|
6.
|
Determine the crankshaft bearing play.
Calculation formula: average crankshaft bearing diameter minus average crankshaft bearing journal diameter.
|
|
7.
|
Nominal-Actual comparison.
Permissible crankshaft bearing play: 0.005-0.059 mm (0.0002-0.0023 in).
