Connecting Rod: Testing and Inspection
Bolt Inspection
INSPECT CONNECTING ROD BOLTS
1. Install the cap nut to the connecting rod bolt. Check that the cap nut can be turned easily by hand to the end of the thread.
2. If the cap nut cannot be turned easily, measure the minimum outside diameter of the connecting rod bolt with vernier calipers.
Standard outside diameter: 7.80 - 7.90 mm (0.3071 - 0.3110 inch)
Minimum outside diameter: 7.60 mm (0.2992 inch)
NOTE: If the location of minimum diameter cannot be judged by visual inspection, measure the outer diameter at the location shown in the
illustration.
If the outside diameter is less than limit, replace the connecting rod bolt and nut as a set.
