NOTE
Do not rotate crankshaft while gauging
plastic is installed.
5) Remove bearing caps, and measure gauging plastic
(2) width at its widest point using scale (1) on
gauging plastic envelop. If clearance exceeds its
limit, replace bearing. Always replace both upper
and lower inserts as a unit.
A new standard bearing may produce proper
clearance. If not, it will be necessary to regrind
crankshaft journal for use of 0.25 mm undersize
bearing.
After selecting new bearing, recheck clearance.
Main bearing clearance
Standard: 0.025 – 0.045 mm (0.0010 – 0.0018 in.)
Limit: 0.065 mm (0.0026 in.)
NOTE
After checking the bearing clearance, make
sure that thread deformation of each bearing
cap No.1 bolt according to previous
mentioned Step 4) once again.
Selection of Main Bearings
Standard bearing
If bearing is in malcondition, or bearing clearance is out
of specification, select a new standard bearing according
to the following procedure and install it.
1) First check journal diameter. As shown in the figure,
crank web No.2 has stamped numbers.
Three kinds of numbers (“1”, “2” and “3”) represent
the following journal diameters.
Stamped numbers on crank web No.2 represent
journal diameters marked with an arrow in the figure
respectively. For example of M13 engine, stamped
number “1” indicates that corresponding journal
diameter is 44.9940 – 45.0000 mm (1.7715 – 1.7716
in.).
