What's wrong?
The Grade 9 capscrews on 2017-2018 Altec Aerial Device vehicles help hold the rotation bearing in place. That bearing supports the part of the aerial device that turns, so the fasteners have to keep steady clamping force while the equipment rotates and works under load.
On these vehicles, the rotation bearing fasteners are subject to stress corrosion cracking. That means a fastener under load develops cracks as metal stress and corrosion act together. Customers reported broken fasteners with head marking 3050, and Altec traced the issue to that lot. If a capscrew cracks or breaks, it no longer holds the bearing as designed.
Do not wait for a dashboard warning or driving symptom. The warning sign comes from inspection: the fasteners are supposed to be checked periodically for loose, broken, or cracked pieces.
Who's affected?
The affected units share the same Grade 9 capscrew tied to the structural fastener issue.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Cracked rotation bearing fasteners can break and allow the pedestal and turntable to separate, increasing the risk of death or injury. Keep required inspections current and treat any loose, broken, or cracked fastener as a reason to stop using the equipment until it is repaired. Repair is free at any franchised Altec dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Altec Aerial Device is included in this recall.
- Contact a franchised Altec dealer to schedule the free rotation-bearing-fastener replacement that fixes the cracking fasteners.
- Bring the recall notice if Altec mailed one. If not, reference recall number 21V239 when you call.
- Avoid using the aerial device for lift work until the repair is complete, because cracked fasteners can let the pedestal and turntable separate.
What happens at the repair

Frequently asked questions
What is recall 21V239?
Recall 21V239 covers 120 2017-2018 Altec Aerial Device vehicles with rotation bearing fasteners that are subject to stress corrosion cracking. Cracked fasteners can break and separate the pedestal from the turntable, increasing the risk of death or injury. Altec dealers replace the fasteners for free.
What should I do if my 2017-2018 Altec Aerial Device is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 21V239. If it is, contact an Altec dealer or Altec customer service at 1-877-462-5832 to schedule replacement of the rotation bearing fasteners. Reference Altec recall number CSN 807 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Altec's remedy says dealers will replace the rotation bearing fasteners free of charge. Parts and labor are covered through the recall repair.
What is the safety risk?
The safety risk is separation between the pedestal and turntable if cracked rotation bearing fasteners break. That separation increases the risk of death or injury. Until the fasteners are replaced, use the VIN result and dealer guidance to decide whether the vehicle belongs in service.
What if I bought this Altec Aerial Device used?
The free recall repair still applies. Recall coverage follows the vehicle, not the first owner. Check your VIN to confirm whether your specific 2017-2018 Altec Aerial Device is included, then call an Altec dealer or Altec customer service with recall number CSN 807.
