2. Record the main bearing code found on the back of the crankshaft.
3. Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings determine
the required bearing grade for each main bearing.
zRead the first letter of the engine block main bearing code and the first letter of the
crankshaft main bearing code.
z Read down the column below the engine block main bearing code letter, and across the
row next to the crankshaft main bearing code letter, until the two intersect. This is the
required bearing grade for the number one crankshaft main bearing.
z As an example, if the engine block code letter is "F" and the crankshaft code letter is "D",
the correct bearing grade for this main bearing is a "2".
z Repeat this process for the remaining four main bearings. Klj . 3 ba

block, prior to installing the bearing caps
NOTE: Install the thrust bearing to the rear main bearing cap and lubricate it with clean engine
oil.
NOTE: Install the crankshaft lower main bearings into the main bearing caps and lubricate them
with clean engine oil.

must be cleaned with metal surface cleaner. Allow the surface to dry until there is no sign of
wetness or four minutes, whichever is longer. Failure to follow this procedure can result in future
oil leakage.
Apply a 4 mm (0.16 in) bead of silicone gasket and sealant around the rear oil seal retainer
plate sealing surface. Also apply a bead of silicone gasket and sealant at the junction where the
cylinder block, oil pan and rear oil seal retainer plate meet. Klj . 33 ba
