Check Crankshaft Bearing Clearance (With Micrometer Gauge Internal Measuring Device)
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
- Install and tighten the crankshaft bearing cap tie plate and the crankshaft bearings as shown above.
- Measure the crankshaft bearing diameter at 3 points.
Measure in areas as shown (1) with an internal measuring device.
Calculate the average crankshaft bearing diameter.
Formula: 1. result + 2. result + 3. result / 3.
- Measure the crankshaft bearing journal diameter at 2 points between (1) and (3) and between (2) and (4) with the micrometer gauge.
- Calculate the average crankshaft bearing journal diameter.
Formula: 1. result + 2. result / 2.
- Determine the crankshaft bearing play.
Calculation formula: average crankshaft bearing diameter minus average crankshaft bearing journal diameter.
- The crankshaft bearing play should be 0.007-0.031 mm (0.00028-0.00122 in).
NOTE:
The bolts can be reused for checking the crankshaft bearing play.
