3) Place a piece of gaging plastic (1) the full width of bearing
(parallel to crankshaft) on journal, avoiding oil hole.
4) Tighten bearing cap No.1 bolts (1) – (10) and No.2 bolts (11)
– (20) gradually as follows.
a) Tighten bolts (1) – (10) to 30 N·m (3.0 kg-m, 22.0 lb-ft)
according to numerical order in figure.
b) In the same manner as in Step a), tighten them to 50 N·m
(5.0 kg-m, 36.5 lb-ft).
c) In the same manner as in step a), retighten them to 60°.
d) Tighten bolts (11) – (20) to 22 N·m (2.2 kg-m, 16.0 lb-ft)
according to numerical order in figure.
Tightening torque
Crank shaft bearing No.1 bolts (1) – (10)
: 50 N·m (5.0 kg-m, 36.5 lb-ft) and extra tighten 60°
Crank shaft bearing No.2 bolts (11) – (20)
: 22 N·m (2.2 kg-m, 16.0 lb-ft)
NOTE:
Do not rotate crankshaft while gaging plastic is installed.
5) Remove bearing caps and using scale (1) on gaging plastic
(2) envelop, measure gaging plastic width at its widest point.
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 main bearing clearance, make sure that
replace bearing cap No.1 bolts new one.
