Check Crankshaft Bearing Clearance (With Micrometer Gauge Internal Measuring Device)
WARNING: This page is about a different variant/trim than selected.
- 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 to 50 N.m (37 lb ft)
- Second pass to 45°
- Third pass to 15°
- 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).
