ENGINE 3-65CRANKSHAFT THRUST BEARING• With the crankshaft, right-side thrust bearing and left-sidethrust bearing inserted in the upper crankcase, measure thethrust clearance on the left side by using the thickness gauge.L: Left-side thrust bearingR: Right-side thrust bearingNOTE:Pull the crankshaft to the generator side, so that there is noclearance on the right-side thrust bearing. Thrust clearance:Standard: 0.055 – 0.110 mm 09900-20803: Thickness gauge• If the thrust clearance exceeds the standard range, adjust thethrust clearance by the following procedures.CRANKSHAFT THRUST CLEARANCE ADJUSTMENT• Remove the right-side thrust bearing and measure its thicknesswith a micrometer.• If the thickness of the right-side thrust bearing is below standard,replace it with a new one and once again perform thethrust clearance measurement listed above, checking tomake sure it is within standard. Right-side thrust bearing thickness:Standard: 2.425 – 2.450 mm 09900-20205: Micrometer (0 – 25 mm)• If the right-side thrust bearing is within the standard range,reinsert the right-side thrust bearing and remove the left-sidethrust bearing.• As shown in the illustration, measure the clearance by using athickness gauge before inserting of the left-side thrust bearing.• Select a left-side thrust bearing from the selection table.(3-66)
