• When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-96, " Disassembly
and Assembly " .
• If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
• Measure the outer diameters (“d 1”, “d 2”) at two positions as shown.
• If reduction appears in a position other than “d 2 ”, regard it as “d 2”.
• If it exceeds the limit (a large difference in dimensions), replace main bearing cap bolt with a new one.
CONNECTING ROD CAP BOLT OUTER DIAMETER
• Measure the outer diameter “d” at position as shown.
• If reduction appears in a position other than “d”, regard it as “d”.
• When “d” falls below the limit (when it becomes thinner), replace connecting rod cap bolt with a new one.
FLYWHEEL DEFLECTION
• Measure the deflection of flywheel contact surface to clutch with a
dial indicator.
• If measured value is out of the standard, replace flywheel. Standard: There must be crush height. PBIC1646E
