1. Measure the valve clearance as follows.

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

  • If the valve clearance exceeds the space the tappet. (See VALVE CLEARANCE ADJUSTMENT.)

  Note

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

  Standard [Engine cold]
  IN: 0.22-0.28 mm {0.0087-0.0110 in} (0.25±0.03 mm {0.0098±0.0011 in})
  EX: 0.27-0.33 mm {0.0106-0.0130 in} (0.30±0.03 mm {0.0118±0.0011 in})

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

  • If the valve clearance exceeds the standard, replace the tappet. (See VALVE CLEARANCE ADJUSTMENT.)

  Note

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