Bulletin Summary
Altec has learned that on certain AT37-G aerial devices built from November 2007 to April 2018, the rear torsion bar swing arm can interfere with the long runner channels under the body as the torsion bar rotates during road travel. The interference can cause wear issues and can cause welds on the body mounting angles or cross members to develop cracks.
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.
