Service bulletin SB2307

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

DESCRIPTION: Van Hool has determined that some of the seven fasteners securing the automatic belt tensioner base plate are subject to slackening. Tests have shown that these fasteners must be installed with Loctite 243 and tightened to a torque of 90 ± 10 Nm (65 ± 7 ft.lbf). To address this issue, Van Hool is conducting a field change program whereby the seven fasteners must be removed and checked one by one for length and thread pitch (1.75 mm). What to do next is explained in this service bulletin
