CRANKSHAFT - REPLACE/REPAIR
n. Lift crankshaft (14) from cylinder block far
enough to remove upper bearing halves (17)
and thrust bearing (18). Be careful that
connecting rods do not scratch crankshaft.
3. INSTALL MAIN BEARINGS (15 AND 17).
Be sure cylinder block bearing bores, backsides of
bearings, and inner surface of bearing caps are clean and
dry. Oil on these areas could cause less heat transfer
between the bearings and the block which, in turn, could
cause overheated bearings.
If removal was necessary, install fourteen ring
Place new lower bearing halves (15) in bearing
caps (13) with tab inserted in cap groove.
At main bearing positions 1 through 5 and 7, align
tab of upper bearing half (17) with groove in
bearing bore (cylinder block), and press
bearing half into place.
Align tab of thrust bearing (18) with groove in
cylinder block at main bearing position 6, and
press thrust bearing into place.
Apply Lubriplate 105 to the inside surfaces of the
upper and lower bearing halves and thrust
