3-9. CRANKSHAFT MAIN BEARINGS REPLACEMENT (CONT)
Slowly turn crankshaft (1) so the
bearing removal/installation tool
pushes against the end of the
bearing opposite the tab, and upper
bearing half (5) is out of the cylinder
Remove bearing removal/
installation tool from crankshaft (1)
Remove lower bearing half (6) from
bearing cap (3). Keep main bearings
and bearing caps together as a set.
When bearings are reused, each bearing must be installed in its original location
because the bearing surfaces have a wear pattern matched to the crankshaft journals.
Repeat Steps (a) through (f) for remaining main bearing positions (2 through 5) and thrust
bearing (2) at main bearing position (6).
Never use any type of rough material or tools such as sandpaper, emery or crocus cloth,
files, or glassbead cleaning equipment to clean bearings.
See cleaning instructions (Para 2-12).
Apply a light coat of oil over the bearings and the bearing surface in the bearing caps if
the bearings are not going to be installed within one hour after cleaning.
