Inspection of the Saddle Tank Areas
p4 dm 25.02.000
- Ensure fuel tanks are secured to their mounting brackets
and that the mounting brackets are secured to the frame.
If equipped with fuel tank shutoff valves, be sure the valves are fully open.
- Inspect visible frame rails for missing bolts, shiny areas, or rust streaks. Check all visible crossmembers for damage or signs of looseness.
- Inspect visible components of the exhaust system to ensure
connections are tight.Inspect upstream of the aftertreatment device (ATD), if equipped, for cracking or signs of leaks, such as soot trails. Inspect downstream of the ATD for signs of exhaust leaks, such as blistering or warping of nearby components.
Warning: Never operate the engine with the fuel
tank shutoff valves partially closed. This could damage the fuel pump,
causing sudden loss of engine power, possibly resulting in serious
personal injury due to reduced vehicle control.
