Removal and Inspection
1. Remove the two retaining bolts from the bearing holders, 1.
2. Remove the bearing holders and bearing liners, 2 and 3.
3. Position a piece of plastigauge across the full width of the bearing liners.
4. Install the bearing holder and tighten the bolts to 49.0 – 53.9 N⋅m (36.2 – 39.8 ft. lbs.).
NOTE: Do not permit the bearing holder to rotate, even the slightest amount.
5. Remove the bearing holders and measure the width of the flattened plastigauge using the gauge printed on the plastigauge package.
6. Replace components or grind the crankshaft to the next undersize bearing as required to obtain the correct clearance. See “Specifications” later in this section.
7. Check the thrust bearings, 4, for wear, poor contact, burning, or other defects. Using a micrometer measure the washer thickness. If washer thickness is not within allowable limits or found to be defective, the washers must be replaced.
