GENERAL INFORMATION
Two different oil filter mounting adapter designs
are used, one for engines with the removable
bundle-type oil cooler and another for engines
with the plate-type cooler.
Engines with removable bundle-type oil
coolers — The plunger-style oil filter bypass
relief valve used in early production oil filter
mounting adapters was replaced with a poppet-
style valve in November 1997 (beginning with
engine serial number series 7V). With this
change, the oil filter mounting adapter was
redesigned to accommodate the poppet-style
relief valve and to eliminate the section that
contained the plunger-style valve. When
performing an oil and filter change, it is suggested
that functionality of the poppet-style relief valve
be checked by pushing against the viton disk to
verify spring tension.
Engines with plate-type oil coolers — The oil
filter mounting adapters on these engines are
also fitted with the poppet-style valve. Again, the
functionality of the poppet-style relief valve can
be checked by pushing against the viton disk to
verify spring tension each time the oil and filters
are replaced.
Centri-Max
®
filter assemblies — There are
different style rotors used in both the externally
drained and internally drained Centri-Max
®
assemblies. As such, it is important that the
proper rotor be used in the Centri-Max
®
unit for
which it was designed.
From the inception of the Centri-Max
®
filter
assembly (externally drained), the rounded end of
the original rotor (part No. 236GB244A) had
several straight ribs radiating from the center of
the rotor, like spokes of a wheel.
