The part numbers in Table 1 are listed in the order in which the changes were implemented. The new "thick wall" pans are direct replacements for each of the former pans. The former pans have been canceled. When replacing the oil pans on these engines, use the new "thick wall" pan. For engines with pans that already include additional baffles, it is not necessary to replace the currently installed pan. Table 2 lists the effective engine serial numbers for the two latest pan designs. Engines with serial numbers prior to those listed in Table 2 can be updated to the increased-baffle design by adding the required quantity of 172-0915 Baffles.
A procedure has been developed to repair earlier pans that have cracked, and to add the new 172-0915 Baffles to the early ("first change") pans. To obtain this procedure, contact the 3500 Product Group at (765) 448-5911.
