1D-74 Engine Mechanical:
2) Measure the thrust clearance "a" between the left-
side thrust bearing and crankshaft using the
thickness gauge. If the thrust clearance exceeds the
standard range, adjust the thrust clearance.
NOTE
Pull the crankshaft to the left (starter clutch
side) so that there is no clearance on the
right-side thrust bearing.
Special tool
(A): 09900–20803 (Thickness gauge)
Crankshaft thrust clearance "a"
Standard: 0.055 – 0.110 mm (0.0022 – 0.0043 in)

Selection
1) Remove the right-side thrust bearing and measure
its thickness using the micrometer. If the thickness of
the right-side thrust bearing is below standard,
replace it with a new bearing and measure the thrust
clearance again, as described above.
Special tool
(A): 09900–20205 (Micrometer (0 – 25 mm))
Right-side thrust bearing thickness
Standard: 2.425 – 2.450 mm (0.0955 – 0.0965 in)
2) If the right-side thrust bearing is within the standard
range, reinsert the right-side thrust bearing and
remove the left-side thrust bearing.
3) With the left-side thrust bearing removed, measure
the clearance "a" using the thickness gauge as
shown.
