ENGINE MECHANICALS
6. Inspection and adjustment of valve clearances
The measurement and adjustment of valve clearances are
carried out when each of the pistons of the No. 1 and No. 4
cylinders is set to the top dead center at the end of the
compression stroke.
NOTE:
• The valve clearance adjustment is performed normally
when
the
engine is in a hot condition.
• "Hot engine condition" denotes a condition in which the
cooling water temperature is 75 - 85°C and the engine
oil temperature is above 65°C.
However, when the engine has been overhauled, it is
necessary to adjust the valve clearances while the en-
gine is cold and to readjust the valve clearances in a hot
condition after warming up the engine.
