When a new or rearound crankshaft is installed, all new main and connecting rod
bearing shells and-thrust washers must be installed. If used components are-installed,
short life will result.
(1) Install upper main bearing shells (10) in block. If bearings are being reused, install them in
same locations from which they were removed.
(2) Apply clean engine oil to upper bearing shells and crankshaft main bearing journals.
Do not damage journals or main
bearing shells when lowering
crankshaft into position. Damage
will result in short component life.
Position crankshaft on upper bearing
shells in cylinder block using Iifting
Install upper crankshaft thrust
washers (11) on each side of rear
main bearing support with grooved
side of thrust washers toward
crankshaft thrust surfaces.
Install used bearings in same
bearing caps from which removed.
(5) Install lower main bearing shells (8) in
bearing caps (7) and two thrust
washers (9) to rear main bearing cap.
Main bearing caps are bored in
position and stamped 1, 2, 3, 4, and
5, Install caps with identification
stamp on right side of engine.
(6) Install five main bearing caps (7)
along with mating lower bearing
shells (8) and lower thrust washers
