Figure 65— Checking Crankshaft Run-Out
Measure (Figures 64 and 65)
• Main bearing and connecting rod journal diameters
(figure 64). Compare with “ Specifications.” Grind or
replace the crankshaft if necessary.
• Main bearing and connecting rod journals for taper
and out-of-round (figure 64). If the journals are
tapered or out-of-round more than 0.0254 mm
(
0.001
inch), grind or replace the crankshaft.
• Crankshaft run-out (figure 65).
A. Mount the crankshaft in V-blocks on main jour
nals 1 and 5.
B. Use a dial indicator to measure the crankshaft
runout, as shown in figure 65.
C. If the main journals are misaligned, the crank
shaft is bent and must be replaced, along with
the main bearings.

Crankshaft main and connecting rod bearings are
available in 0.0254 mm (0.001 inch), 0.0508 mm (0.002
inch), 0.2540 mm (0.010 inch), and 0.5080 mm

OIL SEAL RETAINER
(5.0L AND 5.7L ENGINES)
❖
Disassemble (Figure 66)
• Crankshaft rear oil seal. Insert a screwdriver into
the notches provided in the seal retainer and pry
the seal out (figure
66
).
I?
Clean
All traces of old gasket from the retainer.
Inspect
Retainer for cracks, porosity, and damage to the
sealing surfaces.
Important
• Install the new crankshaft rear oil seal with the
proper tool after the retainer is assembled to the
engine, as outlined later.
ASSEMBLY OF THE ENGINE
PRIOR TO ASSEMBLY
The importance of cleanliness during the assembly
procedure cannot be overstressed. Dirt will cause pre
mature wear of the rebuilt engine.
Lubricate all moving parts lightly with engine oil or
engine assembly lubricant (unless specified otherwise)
during assembly. This will provide initial lubrication
when the engine is started.

BEARING INSTALLATION
Main bearings are the precision insert type and do
not use shims for adjustment. If clearances are exces
sive, a new bearing will be required. Service bearings
are available in standard size and 0.0254 mm (0.001
inch), 0.0508 mm (0.002 inch), 0.2540 mm (0.010 inch),
and 0.5080 mm (
