crankshaft bearing caps.
(2) Using vernier calipers, measure the distance
between the crankshaft bearing cap's edge and
the lower crankshaft bearing's edge.
Dimension (A - B):
0.7 mm (0.0276 in.) or less
NOTICE:
Do not apply engine oil to the crankshaft
bearings and the contact surfaces.
7. INSTALL CRANKSHAFT THRUST WASHER SET

indicate the installation position.
(c) Apply a light coat of engine oil to the threads and
under the heads of the crankshaft bearing cap bolts.
(d) Temporarily install the 8 crankshaft bearing cap
bolts to the inside positions.
(e) Insert the crankshaft bearing cap with your hand
until the clearance between the crankshaft bearing
cap and the cylinder block is less than 6 mm (0.23
in.) by marking the 2 internal crankshaft bearing cap
bolts as a guide.
Bolt length:
100 to 102 mm (3.94 to 4.02 in.)
(f) Using a plastic hammer, lightly tap the crankshaft
bearing cap to ensure a proper fit.
