CRANKSHAFT (Continued)
CAUTION: The bedplate to cylinder block mateing
surface must be coated with sealant prior to instal-
lation. Failure to do so will cause severe oil leaks.
NOTE: The installation time to install the bedplate
after the sealant has been applied is critical.
NOTE: Make sure that the bedplate and cylinder
block sealing surfaces are clean and free of oil or
other contaminants. Contaminants on the sealing
surfaces may cause main bearing distortion and/or
oil leaks.
(5) Apply a 2.5mm (0.100 inch) (Fig. 58) bead of
Mopar Gen II Silicone Rubber Adhesive sealant to
the cylinder block-to-bedplate mating surface as
shown (Fig. 59).
