CRANKSHAFT THRUST BEARING
• With the crankshaft, right-side thrust bearing and left-side
thrust bearing inserted in the upper crankcase, measure the
thrust clearance on the left side by using the thickness gauge.
®: Right-side thrust bearing
CD:
Left-side thrust bearing
NOTE:
Pull the crankshaft to the right-side,
so that there is no clearance
on the right-side thrust bearing.
_ Thrust clearance:
Standard: 0.070 - 0.110 mm (0.0028 - 0.0043 in)
iT'Oot.
09900-20803: Thickness gauge
• If the thrust clearance exceeds the standard range, adjust the
thrust clearance by the following procedures.
CRANKSHAFT THRUST CLEARANCE ADJUSTMENT
• Remove the right-side thrust bearing and measure its thick-
ness with a micrometer.
• If the thickness of the right-side thrust bearing is below stan-
dard, replace it with a new one and once again perform the
thrust clearance measurement listed above, checking to
make sure it is within standard.
_ Right-side thrust bearing thickness:
Standard: 2.420 - 2.440 mm (0.0953 - 0.0961 in)
irooh
09900-20205: Micrometer
• If the right-side thrust bearing is within the standard range,
reinsert the right-side thrust bearing and remove the left-side
thrust bearing.
• As shown in the illustration, measure the clearance by using a
thickness gauge before inserting of the left-side thrust bear-
ing.
• Select a left-side thrust bearing from the selection table.
