Terex is recalling 74 2009-2013 HR40, LT38, LT40, LTM40, NT29, TL37, TPL40, and L13I aerial devices built on Ford Super Duty chassis because oil can leak from the PTO pressure switch onto the exhaust thermal blanket.

What's wrong?
The PTO assembly is the power takeoff unit that lets the truck engine run equipment on the Terex aerial device, such as the boom system. The pressure switch is part of that PTO setup and helps the system read oil pressure while the equipment is operating. It sits close enough to the exhaust area that a leak matters.
On affected 2009-2013 Terex HR40, LT38, LT40, LTM40, NT29, TL37, TPL40, and L13I aerial devices, oil can leak from the PTO pressure switch. The recall covers units built on Ford F-350, F-450, or F-550 Super Duty chassis with a 6.8L engine and certain Muncie Power Products PTO assemblies. If the leaking oil lands on the thermal blanket over the exhaust, heat from the exhaust area creates the hazard.
There is no warning sign before failure. An owner or operator should not count on a light, noise, smell, or visible leak before the problem becomes serious.

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?
Oil leaking onto the thermal blanket over the exhaust raises fire risk when exhaust heat is present. If you smell burning oil, see smoke, or find oil near the exhaust area, stop using the vehicle and call the dealer for repair guidance. Repair will be free at any franchised Terex dealer once available.
What should I do?
- Check your VIN to confirm your 2009-2013 Terex HR40, LT38, LT40, LTM40, NT29, TL37, TPL40, or L13I aerial device is included in this recall.
- Use Terex's owner notice, if you have it, or call Terex customer service at 1-605-882-4000 for current repair instructions.
- Reference recall number 14V371 when you call Terex or the dealer service desk.
- Schedule the free pressure-switch-kit repair that moves the leaking PTO pressure switch away from the exhaust system.
- Avoid operating the aerial device until Terex or the dealer confirms the repair plan, because leaking oil on the exhaust blanket raises the fire risk.
What happens at the repair
The source remedy says Terex dealers install a new pressure switch kit for the PTO system. Once the dealer repair is available, a Terex technician will move the pressure switch away from the exhaust system so oil leakage is kept away from the thermal blanket around the exhaust. The final dealer repair will be free once available, with parts and labor covered under the recall.

Frequently asked questions
What is recall 14V371?
Recall 14V371 covers 74 2009-2013 Terex aerial devices with certain Muncie PTO assemblies. Oil can leak from the PTO pressure switch onto a thermal blanket near the exhaust, increasing fire risk. Terex dealers install a new pressure switch kit for free.
What should I do if my 2009-2013 Terex HR40, LT38, LT40, LTM40, NT29, TL37, TPL40, or L13I is on this recall?
Check your VIN to confirm your specific Terex aerial device is included in recall 14V371. If it is, contact a Terex dealer or Terex customer service at 1-605-882-4000 and reference recall SN611. The repair is free.
Is the Terex recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Terex will install the updated pressure switch kit free of charge. The repair moves the switch away from the exhaust system.
What is the safety risk?
The safety risk is fire. Oil from the PTO pressure switch can soak into the thermal blanket covering the exhaust. Heat from the exhaust can then raise the risk of a vehicle fire, so confirm your VIN and schedule the free repair if your unit is included.
What if I bought the Terex 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 Terex unit is included, then contact a Terex dealer or Terex customer service with recall number 14V371 or SN611.
