Service bulletin SIL 745

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

The affected units were manufactured with a clamp-style boom rest socket that is attached to the subbase of the unit. Altec has discovered that cracks may develop in the bottom plate of the boom rest socket. Altec has designed reinforcement plates to be installed on the boom rest socket structure. These are used to repair units which have developed cracks and to prevent cracks from occurring on units which have not developed cracks. Clamp Boom Rest Reinforcement Kits are available containing these parts for specific unit models. The kit part numbers are shown below. Altec requires that the appropriate kit be installed on each unit no later than the next regular maintenance interval but no later than 90 days from the receipt of this SIL
