The problem
On certain emergency vehicles equipped with cummins isl cm850 diesel engines, the connecting rods which transfer energy from the piston to the crankshaft are defective and can result in seizure of the piston pin. A piston pin seizure can result in a mission-disabling engine failure.
The risk
This condition could ultimately result in a loss of vehicle power (engine stall) increasing the risk of a crash.
The fix
Paccar is working with cummins to replace the connecting rods free of charge (please see 06e037). Owners may contact cummins at 1-800-diesels or kenworth at 1-425-828-5440.
