Connecting rod installation precautions
1. Install the connecting rod bearing onto the connecting rod with the projection in
alignment.
Apply oil generously to the bearing surface.
2. For installation, the word "YAMAHA" or the letter "Y" facing leftward.
3. Apply a generous amount of oil or oil-diluted molybdenum grease to the threads
and seating surfaces of the connecting bolts and to the connecting rod seating
surface; then, install the connecting rods with aligning marks on the rods and caps
in alignment with the individual crank pins. Using the nut rotation method, tighten
the caps with an F-type torque wrench to 19.6±1.96 Nm (2.0±0.2 kgf•m), and then
retighten them in a rotation angle of 150°±5°.
4. If the extension method is used, adjust the bolt extension to 300±50 µm.
5. For installation, take care to allow no steps forming on the connecting rod contact
surfaces.
6. Provide protection for the connecting rod contact surfaces.
