    The bolts can be reused for checking the crankshaft bearing play.

  1. Install and tighten the crankshaft bearing cap tie plate and the crankshaft bearings as shown above.
  2. GM2189635

    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.

  3. GM2189634

    Measure the crankshaft bearing journal diameter at 2 points between (1) and (3) and between (2) and (4) with the micrometer gauge.

  4. Calculate the average crankshaft bearing journal diameter.

    Formula: 1. result + 2. result / 2.

  5. Determine the crankshaft bearing play.

    Calculation formula: average crankshaft bearing diameter minus average crankshaft bearing journal diameter.

  6. The crankshaft bearing play should be 0.007 - 0.031 mm (0.00028 - 0.00122 in).
