1. CAUTION: Prevent engine contamination. Always use necessary precautions to prevent
old sealer or gasket material from falling into the engine.
NOTE: Lightly oil all attaching bolt and stud threads before installation, except those
specifying special sealant.
Before beginning to assemble engine:
a. Clean ALL the oil and the old sealer from the oil pan, taking special care to remove ALL the old
sealer from the oil pan gasket groove in the oil pan. Thoroughly wash the oil pan.
b. Clean ALL the old sealer from the rear main bearing cap USING A SCRAPER AND WIRE
WHEEL. The original sealer used during production assembly becomes extremely hard after it
has cured. It is extremely important that ALL the old sealer be removed from joint faces and
grooves.
c. Clean ALL the oil and old sealer from the cylinder block oil pan sealing area and the rear main
bearing cap joint area.
d. After all the parts have been cleaned they must be wiped down with a cleaner that leaves no
residue or film such as Ford Extra Strength Spot Remover B7A-19521-AA meeting Ford
specification ESR-M5B197-A or denatured alcohol.
e. Clean the transmission bell-housing area and the rear of the cylinder block of ALL oil residue.
Verify with a black light that all oil residues have been cleaned from this area.

Lubricate bearings with SAE 50 Service SG oil.
3. Install the lower main bearings in the bearing caps.

5. Check clearance of each main bearing, following the procedure under Fitting Main and Connecting
Rod Bearings in
6. After crankshaft main bearings have been fitted, apply SAE 50 Service SG oil to the journals and
bearings.

ESE-M4G195-A or equivalent in a 1.59mm (1/16-inch) bead in each corner of rear main bearing
cap saddle, the full length of the saddle.
