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.
Remedy
Monaco is working with cummins to recalibrate the engine control module and enhance the engine protection system enabling it to provide early detection of the failure mode and avoid more serious engine damage and resultant safety hazard. Cummins will also install a new valve cover with a crankcase pressure sensor free of charge (please see 07E033). Owners may contact cummins at 800-343-7357 or monaco at 1-800-685-6545.

Monaco recall no. R07007.CUSTOMERS may contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY: 1-800-424-9153); or go to http://www.safercar.gov.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Beaver Coach been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Beaver Coach dealer can also check your VIN. Recall repairs are free.
