6. Measure the valve clearance.

  (1) Rotate the crankshaft clockwise so that the No.1 cylinder is at TDC of the compression stroke.
  (2) Measure the valve clearance at A in the figure.

  • If not within the specification, replace the tappet and adjust the valve clearance to the median value. (See VALVE CLEARANCE ADJUSTMENT [ZJ, ZY].)

Valve clearance [Engine cold]

  IN: 0.27-0.33 mm {0.0107-0.0129 in}
  EX: 0.27-0.33 mm {0.0107-0.0129 in}

  Note

  • Make sure to note down the measured values for choosing the suitable replacement tappets.

  (3) Rotate the crankshaft clockwise 360° so that the No.4 cylinder is at TDC of the compression stroke.
  (4) Measure the valve clearance at B in the figure.

  • If not within the specification, replace the tappet and adjust the valve clearance to the median value. (See VALVE CLEARANCE ADJUSTMENT [ZJ, ZY].)

Valve clearance [Engine cold]

  IN: 0.27-0.33 mm {0.0107-0.0129 in}
  EX: 0.27-0.33 mm {0.0107-0.0129 in}
