NOTE:
If the stretch bolt tightening torque is exceeded remove it. Check its maximum permissible shaft
length (replace if necessary), and tighten it from Stage 1. Unconditionally replace all bolts whose
shaft length exceeds the maximum permissible value.
6. Replace the seal rings and connect the fuel return line to the cylinder head.
7. Replace the seal rings and install the constant-throttle line on the cylinder head.
8. Connect the coolant line to the cylinder head.
