Summary

ON CERTAIN MOTOR HOMES BUILT WITH CUMMINS ISL CM850 DIESEL ENGINES, THE CONNECTING ROD CONTAINS A MACHINING DEFECT IN THE WRIST PIN BUSHING OF THE ROD THAT COULD CAUSE A SEIZURE OF THE PISTON PIN.

Consequence

IF ALLOWED TO PROGRESS, THIS CAN LEAD TO ENGINE FAILURE WITH THE POSSIBILITY OF THE ROD RUPTURING THE LOCK CAVITY, OIL AND DEBRIS ON THE ROADWAY AND VEHICLE CRASH.
