CONROD-CRANK PIN BEARING SELECTION
• Loosen the bearing cap nuts and tap the bolt end lightly with
plastic hammer to remove the bearing cap.
• Remove the rods and mark them to identify the cylinder posi-
tion.
• Inspect the bearing surfaces for any sign of fusion, pitting,
burn, or flaws. If any, replace them with a specified set of
bearings.
NOTE:
Never try to remove or loosen the conrod cap bolts due to their
possible loosening in the rod. Once displaced, the bearing cap
will not be fitted properly.
• Place plastigauge axially on the crank pin avoiding the oil
hole, at TDC or BDC side as shown.
• Tighten the bearing cap with two-step torque values.
NOTE:
When fitting the bearing cap to crank pin, be sure to discriminate
between its two ends, I.D. code side and the other.
I.D. code always faces intake valve side.
