REMOVAL AND INSTALLATION (Continued)
Installation
1. Carefully clean the seal groove in the cap
and block with a brush and solvent.
2. Dip the split lip-type seal halves in clean en-
gine oil.
3. Carefully install the upper seal (cylinder
block) into its groove with undercut side of
seal toward the FRONT of the engine, by ro-
tating it on the seal journal of the crankshaft
until approximately l/8 inch protrudes below
the parting surface.
Be sure no rubber has been shaved from
the outside diameter of the seal by the
bottom edge of the groove. Do not allow
oil to get on the sealer area.
4. Tighten the remaining bearing cap bolts and
torque to specifications.
5 .
Install the lower seal in the rear main bear-
ing cap with undercut side of seal toward the
FRONT of the engine, allowing the seal to
protrude approximately l/8 inch above the
parting surface to mate with the upper seal
when the cap is installed.
6. Apply an even 1.588mm (l/16 inch) bead of
RTV Silicone Rubber Sealer DGAZ-19562-B
or equivalent, to the areas shown, following
the procedure given in the illustration.
Do
not apply sealer to the area forward of
the side seal groove. Install the rear main
bearing cap. Torque the cap bolts to
specifications.
7. Install the oil pump and oil pan. Fill the
crankcase with the proper amount and vis-
cosity oil.
8.
Operate the engine and check for oil leaks.
