  2. Install the upper side rail. To install the side rail, first put one end of the side rail between the piston ring groove and spacer, hold it firmly, and press down with finger on the portion to be inserted into the groove (as illustrated).
    CAUTION: Do not use a piston ring expander when installing the side rail.
  3. Install the lower side rail by the same procedure described in Step 2.

  12. Make sure that the front mark of the piston and the front mark (identification mark) of the connecting rod are directed toward the front of the engine.
  13. When the connecting rod cap is installed, make sure that any cylinder numbers placed on the rod and cap at disassembly match.
  14. When a new connecting rod is installed, make sure that the notches for holding the bearing in place are on the same side.
  15. When assembling, bolts should be fastened using the plastic angle technique as follows.
    1. Apply oil to the threads and matching areas.
    2. Tighten the connecting rod bolt.

    Tightening torque 

    Connecting rod bolt:

    35 Nm (350 kg.cm, 26 lb. ft) +90°

    CAUTION: After removing the connecting rod bolt, do not use it again.
    When using a new bolt, do not tighten the bolt more than 3 times.
  16. Check the connecting rod side clearance.

    Connecting rod side clearance 

    Standard: 0.10 ~ 0.25 mm (0.0039 ~ 0.0098 in.)

    Limit: 0.4 mm (0.0157 in.)
