January 23, 2023 NHTSA CAMPAIGN NUMBER: 23V020000
A detached exhaust silencer can become a road hazard, increasing the risk of a crash.
NHTSA Campaign Number: 23V020
Manufacturer Alamo Group Inc.
Components EQUIPMENT
Potential Number of Units Affected 56
Summary
Alamo Group Inc. (Alamo Group) is recalling certain 2018-2021 AllVac AVRB-18 vehicles. The vibration from vacuum operations could lead to the exhaust silencer welds cracking, resulting in detachment of the exhaust silencer from the vehicle.
Remedy
Gradall Dealers will inspect the exhaust silencer and repair any cracked welds, reattach any detached silencers, and weld a c-shape bracket from the silencer to the power frame, free of charge. Direct-sales owners will be provided instructions and parts, free of charge. Owner notification letters were mailed March 17, 2023. Owners may contact Gradall customer service at 1-800-382-8302.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
Exhaust Silencer Service Kit Instructions
March 2023
Chronology :
In March 2020, Gradall was notified by a customer in Chile that an exhaust silencer for an AllVac AVRB-18 vehicle detached from the vehicle. In discussing this issue with the customer, it was discovered that the operational terrain was extremely rugged. This was considered an isolated incident caused by the terrain on which the vehicle was operating.
In July 2021, as part of a broader product standardization effort, Gradall changed the model of exhaust silencer used in AllVac AVRB-18 vehicles and secured that silencer to the frame of the vehicle with c-clamp bracket.
In February 2022, Gradall was notified by another owner of an AllVAC AVRB-18 built prior to the July 2021 product standardization that this same issue had occurred (i.e., the exhaust silencer detached from the vehicle) while the vehicle was being driven on a public roadway. This customer also observed cracks in the welds on exhaust silencers on one other pre-July 2021 AllVac AVRB-18 vehicle that the customer owns.
In October 2022, Gradall conducted a safety investigation to assess the failure mode, the failure rate, and potential causes. As part of that investigation, Gradall reviewed information reported by the customer in February 2022 and contacted another customer who operates a number of AllVac AVRB-18 vehicles. The second customer also observed cracks in the welds on the exhaust silencer and reported that two exhaust silencers had broken from the frame, but not detached from the vehicle.
Gradall also inspected AllVac AVRB-18 vehicles that were manufactured after the July 2021 design change.
None of those vehicles had cracks in the welds or detached exhaust silencers.
As of January 13, 2023, Alamo was aware of no warranty claims, no deaths, and no injuries related to this issue.
The customer notifications in March 2020 and February 2022 are the only such notifications or reports Alamo has received on this issue. On January 13, 2023, Alamo decided to declare a voluntary safety recall.

March 2023 Dear [CUSTOMER],
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Alamo Group has decided that a defect which relates to motor vehicle safety exists in certain AllVac vacuum vehicles manufactured by Gradall in 2018 – 2021, including in the AllVac vehicles with the VIN(s) shown above. As a result, Alamo Group is conducting this safety recall. We apologize for this inconvenience. We are committed to your safety and satisfaction with our products, and we request that you remedy your vehicle(s) promptly.
Why is my AllVac vehicle recalled?
The vibrations from vacuuming operations are leading to cracks in the welds on the exhaust silencer. If the welds on exhaust silencer have cracks, then the exhaust silencer could detach, increasing the risk of a motor vehicle crash. What will we do? The corrective action is to inspect and repair the welds on the exhaust
silencer, re-attach any detached silencers, and attach c-shape brackets
from the power frame to the exhaust silencer. This remedy will be performed free of charge. The repair takes about 2 hours to complete. What should you do? Please contact the Gradall/Vacall Parts Department or Warranty
Administrator (at 1-800-382-8302) to order the necessary parts and perform the remedy in accordance with the attached instructions.

Country : United States Chronology :
In March 2020, Gradall was notified by a customer in Chile that an exhaust silencer for an AllVac AVRB-18 vehicle detached from the vehicle. In discussing this issue with the customer, it was discovered that the operational terrain was extremely rugged. This was considered an isolated incident caused by the terrain on which the vehicle was operating. In July 2021, as part of a broader product standardization effort, Gradall changed the model of exhaust silencer used in AllVac AVRB-18 vehicles and secured that silencer to the frame of the vehicle with c-clamp bracket. In February 2022, Gradall was notified by another owner of an AllVAC AVRB-18 built prior to the July 2021 product standardization that this same issue had occurred (i.e., the exhaust silencer detached from the vehicle) while the vehicle was being driven on a public roadway. This customer also observed cracks in the welds on exhaust silencers on one other pre-July 2021 AllVac AVRB-18 vehicle that the customer owns. In October 2022, Gradall conducted a safety investigation to assess the failure mode, the failure rate, and potential causes. As part of that investigation, Gradall reviewed information reported by the customer in February 2022 and contacted another customer who operates a number of AllVac AVRB-18 vehicles. The second customer also observed cracks in the welds on the exhaust silencer and reported that two exhaust silencers had broken from the frame, but not detached from the vehicle.
Gradall also inspected AllVac AVRB-18 vehicles that were manufactured after the July 2021 design change. None of those vehicles had cracks in the welds or detached exhaust silencers. As of January 13, 2023, Alamo was aware of no warranty claims, no deaths, and no injuries related to this issue. The customer notifications in March 2020 and February 2022 are the only such notifications or reports Alamo The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-020

The information contained in this report was submitted pursuant to 49 CFR §573
has received on this issue. On January 13, 2023, Alamo decided to declare a voluntary safety recall.
Description of Remedy :
Description of Remedy Program : Gradall will provide direct sale customers and dealers with instructions to
examine all welds on the exhaust silencer and repair any cracked welds, reattach any detached silencers, and weld a c-shape bracket from the silencer to the power frame.
Affected vehicle owners will be notified by first class mail. Affected vehicle owners who are direct sale customers will be provided the instructions and parts to remedy their vehicles and receive reimbursement. Affected vehicle owners who purchased their vehicle from a dealer will be directed to take their vehicle to a Gradall affiliated dealer to have the remedy performed free of charge. If this condition was identified and remedied on an affected vehicle prior to this campaign, Gradall will reimburse owners who have incurred the cost of such remedy.
How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production :
The remedy provides additional support for the exhaust silencer with the installation of the c-shape bracket and repairs to any cracked welds.
As of August 1, 2021, Gradall has used a different design and different type of exhaust silencer for all subsequently manufactured AllVac AVRB-18 vehicles. Recall Schedule :
