Introduction
The following procedures contain crucial information on correctly installing the new 162-2501 Hose As and the 258-8917 Protection Sleeve .Note: The 162-2501 Hose As replaces 107-7942 Tube As .Installation Procedure of the Hose Assembly
Illustration 1 g01230674
Remove old 162-2501 Hose As (1). Keep all of the manifold and pump fittings attached.Note: Step 2 is only for 3408E engines.
Remove the 7W-6492 Pipe Plug (2) from the aftercooler housing (3). Install the 8T-6762 Pipe Plug into the aftercooler housing.
Illustration 2 g01230678
Note: Always tighten the fittings with your hand before you use a wrench. Support the hose and the elbow while you tighten in order to avoid the following damage: twisting, kinking and side loading.
Loosen elbow (4) and jam nut (5) .
Hand tighten the nut on the hose (5) to the elbow (4) .
Install the other end of the hose (6) to the pump fitting. Tighten the nut to 125 15 N m (90 11 lb ft).
Hold the elbow (4) in position and torque the jam nut to 145 15 N m (105 11 lb ft).
Support the elbow (4). Tighten the nut (5) on the hose to 125 15 N m (90 11 lb ft).
Illustration 3 g01230687
Illustration 3 shows the routing of the 162-2501 Hose As (8). The hose is routed from the rail, around the rear of the fuel transfer pump (9), and into the 90 degree fitting (7) that is installed into the pump.
Illustration 4 g01230689
Some 3408 engines use an aftercooler that is mounted high. The mounting bracket (10) is located close to the 162-2501 Hose As (8). If there is not enough clearance to install the protective sleeve, the hose will need to be loosened and the hose will need to be repositioned. Refer to 5 for repositioning of the hose.
Illustration 5 g01230690
The hose must be realigned if any of the following conditions exist:
Not enough clearance against the fuel transfer pump
Not enough clearance against the support bracket
Loosen the end of the hose (12) .
Loosen the elbow and the jam nut (11). Note: Do not remove the hose.
Reposition the hose in order to acquire the desired clearance.
Hold the end of the hose (12). Tighten the jam nut (11) .Tighten the jam nut to the following torque. ... 143 15 N m (105 11 lb ft)Note: Locking pliers can be used on the crimped portion of the hose. Do not use the locking pliers on the braided portion of the hose. This will damage the hose which will cause a failure.
Tighten the end of the hose (12) .Tighten the end of the hose to the following torque. ... 125 15 N m (92 11 lb ft)Note: If adjustment of the hose is required, make sure that the hose is not bent. Also, ensure that the hose is not twisted. If these conditions exist the PTFE liner can be damaged.Installation of the Protective Sleeve Over the New Hose Assembly
