Installation
1. Clean each crankshaft journal before installing the main bearing insert. Inspect the journals for nicks,
burrs, or bearing pickup that would cause premature bearing wear.
2. Select fit the bearing for proper clearance following procedures under Fitting Main and Connecting
Rod Bearings in
3. NOTE: New bolts must be used for assembling main bearing caps.
NOTE: Make sure that the main bearing caps are installed in their original positions and
orientation.
To install the upper main bearing, lubricate the bearing with heavy engine oil SF. Then place the end
of the bearing over the shaft on the locking tang side of the cylinder blocks (6010) and partially install
the bearing so that Main Bearing Insert TOOL-6331-E or equivalent can be inserted in the journal oil
hole. With tool installed, rotate the crankshaft slowly in the opposite direction of engine rotation until
the bearing tang is seated. Remove the bearing tool.
4. For bearings number one, two, and three, coat the bearing insert and journal with SAE 50 Service SG
meeting Ford specification ESE-M2C39-F and install the bearing cap. Tighten the cap to 90-104 Nm
(66-77 lb-ft).
5. Install the remaining bearings in the same manner. If servicing the rear main bearing, apply sealer to
the cap as shown.
