11. Rotate the crankshaft clockwise, and seat the journals into connecting rod No.

2 and connecting rod No. 3. Line up the mark on the connecting rod and cap,
then install the caps and bolts finger-tight.

12. Tighten the connecting rod bolts to 29 N.m (3.0 kgf.m, 22 lbf.ft).
13. Tighten the connecting rod bolts an additional 90 °.

NOTE:

Remove the connecting rod bolt if you tightened it
