DISASSEMBLY/REASSEMBLY
Piston protrusion check
Tocalculatetherightthicknessforthegasket,theprotrusionbetween
thepistonandthecylinderheadsurfacemustbemeasured.
Useadialindicatorwithbaseplate.Resettozerowhilerestingona
surfaceplate, then position against thecylinder head base plane as
showninthediagram,sothatthedialindicatorrodrestsagainstthe
piston.Nowtakethereading.
Repeattheoperationintheotherthreepoints(goingcrosswise)and
takethereadings.
Calculate the average of these four readings to get the precise
measurement of the protrusion between the piston and the cylinder
headbaseplane.
Choosetheappropriategasketaccordingtothefollowingtable.
Onlyremovetheheadgasketfromitsprotectivewrappingjust
beforeassembly.
See page 26 when tightening the cylinder head
Havingchosentherequiredthickness,mountthegasketasshownin
thegure(seeletterA).
FindthenumberofnotchesinzoneBtondthethicknessofthega-
sketwhenthecylinderheadismounted.
Thegasket thickness given in thetable isthe one obtainedwith the
gasketmountedandtheheadtorqued.
