Bulletin Summary
This Service Bulletin informs affected owners that on certain D45CRTLE and J4500 model coaches equipped with Cummins X12 engines, the top alternator power and ground cables may potentially come in contact with the edge of the clamp mounting bracket and that a shim should be added between the mounting bracket and the clamp. MCI is providing the parts and labor at no cost to the owners.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
