# Service bulletin MI12\-48

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

When performing the next periodic maintenance, check clearance between the 4\-inch OD turbooutlet pipe \(Prevost part number 052953\) and a close support bracket. If evidence of rubbing isfound, i.e. scratched paint on the 4\-inch OD turbo outlet pipe, a modification of the support bracket can be performed in order to increase the clearance between the involved components. The support bracket will remain strong enough for the duty even after being modified.
