Service bulletin TSB140107-091514
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
THIS TECHNICAL SERVICE BULLETIN DESCRIBES THE VERIFICATION AND RESOLUTION OF IMPROPER ROUTING OF THE TWIN CYLINDER AIR COMPRESSOR DISCHARGE LINE LEADING TO AIR COMPRESSOR CRANKSHAFT FAILURES IN CERTAIN ENGINES INSTALLED IN PACCAR VEHICLES. IMPROPERLY ROUTED AIR COMPRESSOR DISCHARGE LINES CAN COLLECT MOISTURE THAT LEADS TO HIGHER LEVELS OF RESTRICTION, WHICH CAN LEAD IN TURN TO FAILURE OF THE AIR COMPRESSOR CRANKSHAFT. IN MANY CASES, THE MOISTURE FREEZES IN THE DISCHARGE LINES, FURTHER ELEVATING THE RESTRICTION. THIS IS A REVISION TO A PREVIOUS COMMUNICATION.
