Valve Clearance: Testing and Inspection
Checking Valve Clearances
This method presupposes that the cylinder head has been removed.
Check and adjust the valve clearance relative to the working range of the tappet.
The tolerances for valve clearance are 19.5 - 0.05 mm minimum and 20.5 - 0.05 mm maximum.
The valve clearance settings are 20.0 mm minimum and 20.4 mm maximum, with a nominal clearance of 20.2 mm.
Valve clearance is equivalent to the distance between the end of the valve stem and the camshaft bearing seat.
Before valve clearances can be checked, the camshafts and valve tappets must first be removed.
Then valve clearance is checked with Valve clearance gauge 83 93 753 as follows:
