Installation
1. Install the crankshaft upper bearing.
• The crankshaft upper bearings have an oil hole
and an oil groove. The lower bearings do not.
• Carefully wipe any foreign material from the
upper bearing.
• Locate the position mark applied at
disassembly if the removed upper bearings are
to be reused.
Note:
Do not apply engine oil to the bearing back faces and
the cylinder block bearing fitting surfaces.

2. Install the crankshaft assembly.
Apply an ample coat of engine oil to the crankshaft
journals and the crankshaft bearing surfaces
before installing the crankshaft.

4. Install the lower crankshaft bearing.
• Before the crankshaft bearing installation,
select the appropriate bearings in accordance
with the description in CRANK BEARING
SELECTION of INSPECTION AND REPAIR.
• Apply the recommended liquid gasket or its
equivalent to the No. 5 crankshaft bearing cap
cylinder body fitting surfaces at the points
shown in the illustration.
Note:
Be sure that the bearing cap fitting surface is completely
free of oil before applying the liquid gasket. ThreeBond
1207B Do not allow the liquid gasket to obstruct the
cylinder thread holes and bearings.
ThreeBond 1207B is a fast-drying liquid gasket. Tighten
the bearing caps immediately after applying the gasket.
