Prepare fixtures «00.2.590» And «00.9.120» and remove all pistons.
Note. The connecting rod head bearings are different from the connecting rod cap bearings. Pay attention to the marking of the size of the crankshaft.
Install a new standard red-marked bearing into the connecting rod cap, install a blue-marked bearing into the lower end of the connecting rod (regardless of the color marking of the connecting rod). Install the pistons in the cylinder block.
Check the radial clearance between the bushings and the connecting rod journal, which should be within 0.016 - 0.055 mm. When checking the clearance, use the old connecting rod cap bolts.
Set piston to bottom dead center (NMT). The procedure for tightening the connecting rod bearing cap is as follows:
- tighten torque 5.0 Nm (0.5 kgf·m);
- tighten torque 20.0 Nm (2.0 kgf·m);
- tighten the bolts by an angle of 80°.
Remove the connecting rod bearing cap, and measure the radial clearance across the width of the flattened plastic gauge wire (see fig. 3.92).To adjust the radial clearance, use new bearing shells or bearing shells with a different color code.
Remove the gauge wire, lubricate the necks and liners with engine oil. Install the connecting rod caps with new, clean, engine oil-lubricated bolts. Tighten the connecting rod cap bolts in three steps:
- 1st reception torque 5.0 Nm (0.5 kgf·m);
- 2nd reception torque 20 Nm (2.0 kgf·m);
- Tighten the 3rd step by 80°.
