SELECTIVE-FIT MAIN BEARING
Using New Cylinder Block and Crankshaft
1. Find the bearing housing grade of cylinder block LH side (L) in
the row of the Selective-fit Service Parts Table.
• If there is a correction stamp, the symbol is the correct one.
2. Find the journal diameter grade of crankshaft front surface in the
column of the Selective-fit Service Parts Table.
3. Find the symbol at the intersection of the selected row and column in the Selective-fit Service Parts Table.
CAUTION:
The setting clearance is different between journal No. 1 and 4, and No. 2, 3, and 5. Use either 2
selective-fit service parts depending on the position.
4. Find the symbol at the intersection in "MAIN BEARING GRADE TABLE" and select it.
NOTE:
Set the upper/lower values for service parts as a set.
