Connecting Rod: Testing and Inspection
Selection, Bolt Inspection
SELECTION
Each rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.0009 inch), in 0.006 mm (0.0002 inch) increments) depending on the size of
its big end bore. It's then stamped with a number (1, 2, 3, or 4) indicating the range. You may find any combination of 1, 2, 3, or 4 in any engine.
Normal Bore Size: 48.0 mm (1.89 inch)
NOTE:
-
Reference numbers or bars are for big end bore size and do not indicate the position of the rod in the engine.
-
Inspect each connecting rod for cracks and heat damage.
CONNECTING ROD BOLT INSPECTION
1. Measure the diameter of each connecting rod bolt at point A and point B.
2. Calculate the difference in diameter between point A and point B.
Point A - Point B = Difference in Diameter
Difference in Diameter:
Specification: 0 - 0.1 mm (0 - 0.004 inch)
3. If the difference in diameter is out of tolerance, replace the connecting rod bolt.
