# Service bulletin SB\_743

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.

- Type: Service bulletin
- NHTSA id: 11018827
- Published by NHTSA: 2025\-06\-02

## NHTSA's summary

Due to the larger size of the PACCAR engine and smaller frame rail design, space constraints within the frame rail area can lead to tight clearances around the engine harness. These tight areas increase the likelihood of harness pinch and rub points may result in insulation damage, wire exposure, or electrical shorts over time.
