    2. After installing a new set of rings, measure the ring-to-groove clearance.

    3. Rotate the rings in their grooves to make sure they do not bind.

    Second Ring Clearance 
    Standard (New):  0.030-0.055 mm (0.002- 0.002 in) 
    Service Limit:  0.13 mm (0.005 in) 
    Top Ring Clearance 
    Standard (New):  0.065-0.090 mm (0.003-0.003 in) 
    Service Limit:  0.15 mm (0.005 in)

    2. Position the piston/connecting rod assembly in the cylinder, and tap it in using the wooden handle of a hammer (A). Maintain downward force on the ring compressor (B) to prevent the rings from expanding before entering the cylinder bore.

    3. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the piston into place.

  5. Connecting Rod Bolt - Inspect

    1. Measure the diameter of each connecting rod bolt at point A and point B.

    2. Calculate the difference in diameter between point A and point B.

    Point A-Point B = Difference in Diameter 

    Difference in Diameter 

    Specification:  0-0.1 mm (0-0.004 in) 

    3. If the difference in diameter is out of tolerance, replace the connecting rod bolt.

  6. Connecting Rod Cap and Bearing Half - Install

    1. Install the connecting rod bearing (A), then line up the mark (B) on the connecting rod (C) and the rod cap (D).

    2. Apply new engine oil to the bolt threads and flanges. Torque the bolts (E) to 20 N.m (2.0 kgf.m, 15 lbf.ft).
