Necessary equipment
KM-470-B Angle Torque Indicator
Inspection Procedure - Crankshaft
1. Lubricate the main bearings with engine oil.
2. Install the upper main bearings in the crankshaft journals of the cylinder block.
3. Install the lower main bearings into the main bearing caps.
4. Install the crankshaft.
5. Check the end play of the crankshaft with main bearings installed.
6. Check the permissible axial play of the crankshaft. follow the paragraph «Engine Specifications» in this section.
7. With the crankshaft installed in the front and rear main bearings, check the crankshaft center journal for allowable eccentricity (beat). follow the paragraph «Engine Specifications» in this section.
Important: Lubricate the crankshaft journals with grease and lightly lubricate the main bearings so that the plastic gauge wire does not break when the main bearing caps are removed.
8. Check all main bearing clearances using a commercially available plastic gauge wire (elastic gauge wire).
9. Cut the plastic gauge wire to the size of the bearing width. Lay it axially between the crankshaft journals and the main bearings.
10. Install the main bearing caps.
11. Install the main bearing cap screws.
Tighten
Tighten the main bearing cap bolts to 50 Nm (37 lb-ft). Using the angle torque gauge KM-470-B, tighten the main bearing cap bolts an additional 45°plus 15°.
12. Remove the main bearing caps.
13. Measure the width of the flattened plastic gauge wire using a ruler. (Plastic gauge wire available for various tolerances).
14. Check bearing clearances for permitted tolerances. follow the paragraph «Engine Specifications» in this section.
Inspection Procedure - Connecting Rods
1. Lubricate the connecting rod bearings with engine oil.
2. Install the upper connecting rod bearings into the connecting rod journals.
3. Install the lower connecting rod bearings into the connecting rod bearing caps.
Important: Lubricate the connecting rod bearing journals and lightly grease the connecting rod bearings so that the plastic gauge wire does not break when the connecting rod bearing caps are removed.
4. Check all connecting rod bearing clearances using a commercially available plastic gauge wire (elastic gauge wire).
5. Cut the plastic gauge wire to the size of the bearing width. Place it axially between the connecting rod journals and the connecting rod bearings.
6. Install the connecting rod bearing caps.
7. Install the connecting rod bearing cap screws.
Tighten
Tighten connecting rod bearing cap bolts to 35 Nm (26 lb-ft). Using the angle torque gauge KM-470-B, tighten the connecting rod bearing cap bolts an additional 45°plus 15°.
8. Remove the connecting rod bearing caps.
9. Measure the width of the flattened plastic gauge wire using a ruler. (Plastic gauge wire available for various tolerances).
10. Check bearing clearances for permitted tolerances. follow the paragraph «Engine Specifications» in this section.
