Valve Clearance Inspection
VALVE CLEARANCE INSPECTION1. 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 standard, replace the tappet.
Note:
^ Make sure to note the measured values for choosing the suitable replacement tappets.
Valve clearance [Engine cold]
IN: 0.22-0.28 mm (0.0087-0.011 in)
EX: 0.27-0.33 mm (0.0106-0.013 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.
