Bulletin Summary
Altec has learned of the potential for washers on the outer race rotation bearing cap screws to overlap the adjacent weld on AT238P and AT335 aerial devices built from October 2019 to November 2021. While there have been no reports of unit failures to date, interference with the weld under the washer could cause cap screw failure.
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.
