ACTION REQUIRED

Show/hide table

A new 468-8629 Fuel Filter support bracket is now used on C175-20 Off-Highway Truck
Engines. The 468-8629 support mounts behind the existing 319-6980 Bracket. The additional bracket allows for the elimination of the 4 long bolts and spacers that mounted the bottom of the bracket to the engine oil pan. The new bracket mounts the fuel filter support up to oil pan rail to provide additional support and stiffness.

Before the rework is initiated, inspect the 319-6980 support assembly for damages, cracks, bent and worn out areas as seen in Image1. Replace the support assembly 319-6980,as required, with the seal-o rings 170-5715 part numbers. Attach to the warranty claim one picture of the damaged 319-6980 support assembly.

Show/hide table

With the engine at a temperature that is safe to work on, remove the fuel line clamps, two above the filter base and two behind the filter canisters, supporting the filter assembly remove the bolts (x12) that are attaching the filter assembly to the filter support assembly (319-6980), lower the filter assembly enough to provide access to the lower filter support assembly fasteners that screw into the oil pan and the front lower bolt that only screws into the filter support assembly, remove all of these bolts, washers and spacers, remove the 5 oil pan bolts immediately behind the filter support assembly as indicated in the attached image. Clean the pan rail surface of built up dirt and any other material that will stop the support from seating properly onto the pan rail surface.

Place the lower support assembly (468-8629) behind the filter support assembly, flat surface to the oil pan flange and the flange with the welded threaded spacers to the filter support assembly, replace the 5 spacers 198-4767 with 106-1242 and bolts 6V-5696 with 372-0687 that were on the oil pan to block, using the new bolts (1x 8T-0722, 3x 8T-0441) with new washers 8T-7934 attach the filter support assembly to the new lower filter support assembly. Tighten fasteners (M10 to 70+/-15 N.m ), (M12 to 120+/-20 N.m), recheck the torque on all fasteners.

Reattach the fuel filter assembly to the filter support assembly, reattach the fuel filter line supports, tighten fasteners M10 to 55+/-10 N.m
