November 2022 IMPORTANT SAFETY RECALL 22V-716 Dear McNeilus Vehicle Owner: Ref: NHTSA Ejector Welds May Fail 22V-716 VIN: <> This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. McNeilus has decided that a defect which relates to motor vehicle safety exists in certain 2021-2023 McNeilus ZR side loaders. These vehicles were built between 6/1/2020- 8/1/2022. Why is a recall being conducted? McNeilus has identified that some vehicles were manufactured with ejector welds that do not meet internal specifications. Over time it could allow for movement of a hydraulic cylinder and ejector outside its normal operation inside the refuse body. If the weldment fails and breaks, pressure and force on the hydraulic cylinder can cause it to penetrate through the side of the truck body. This may increase the risk of injury to individuals in the vicinity of the side of the truck. What are we doing about the problem? McNeilus is sending representatives to repair/replace ejector panels on affected units. ! I M P O R T A N T !  Your McNeilus vehicle is being recalled.  Contact McNeilus at 1-888-686-7278 for any questions.  This recall repair will result in no cost to you.

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 22V-716 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : McNeilus Truck & Manufacturing, Inc. Submission Date : SEP 23, 2022 NHTSA Recall No. : 22V-716 Manufacturer Recall No. : NR Manufacturer Information : Manufacturer Name : McNeilus Truck & Manufacturing, Inc. Address : 524 County Road 34 East P.O. Box 70 Dodge Center MN 55927 Company phone : 507-374-6321 Population : Number of potentially involved : 1,187 Estimated percentage with defect : 100 % Vehicle Information : Vehicle 1 : 2021-2023 McNeilus Zero Radius Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : ALL Power Train : DIESEL Descriptive Information : McNeilus ZR side loaders were manufactured with ejector welds that do not meet internal specifications. Vehicles outside of the recall population were manufactured with ejector welds that meet all internal specifications. Production Dates : JUN 01, 2020 – AUG 01, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Ejector welds do not meet internal specifications and over time could allow for movement of a hydraulic cylinder inside the refuse body. If the weldment eventually fails and breaks, pressure and force placed on the hydraulic cylinder can cause it to penetrate through the side of the truck body. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If the hydraulic cylinder penetrates through the side of the truck body, this may increase the risk of injury to individuals in the vicinity of the side of the truck. Description of the Cause : NR Identification of Any Warning that can Occur : None. Involved Components : Part 573 Safety Recall Report 22V-716 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : Ejector Component Description : Ejector/Packer Component Part Number : 1541835 Supplier Identification : Component Manufacturer Name : Fabtech inc Address : 205 Viola Lane Goodhue Minnesota 55027 Country : United States Chronology : In June 2022, McNeilus received a report of a truck that had a hydraulic cylinder penetrate through the side of the truck body. McNeilus reviewed the incident, and it was believed to be an isolate event as McNeilus had not previously received any similar reports. In July 2022, McNeilus received a report relating to a different truck describing a similar situation and initiated a detailed investigation in conjunction with the parts supplier. The investigation remained ongoing through September 2022, during which McNeilus conducted a thorough review and audit of the parts supplier’s manufacturing processes and facilities and failure modes. The investigation found that the ejector being produced by the supplier was not being produced to McNeilus’ internal specifications including because the ejector was missing welds, the welds were of poor quality or incorrectly sized. In August 2022, the supplier made an update to its processes to ensure McNeilus’ specifications for the welds were being met in production. McNeilus continued to review the issue including the factors affecting whether and how the ejector welds could separate and the potential consequences of an ejector weld failing, in particular the points on the truck body at which the hydraulic cylinder was located and could possibly penetrate the body. On September 19, 2022, McNeilus decided to conduct a recall to address affected vehicles in the field. McNeilus is not aware of any injuries potentially related to this condition. While refuse truck operators do not conduct operations near this area of the truck, there remains some possibility that individuals could be located around the side of the truck and if they were to be present at the time of a failure, this could increase the risk of injury. Part 573 Safety Recall Report 22V-716 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : McNeilus will either send service representatives to repair affected vehicles or ship parts to customers. This will be at no cost to the customers and would file through normal warranty process. How Remedy Component Differs from Recalled Component : New ejector weldment is welded to meet all McNeilus requirements. Identify How/When Recall Condition was Corrected in Production : A stop ship was performed and anything outside of the recall population has been inspected and/or corrected to ensure welds are good on the ejector. Recall Schedule : Description of Recall Schedule : Notifications to customers will be made via a customer letter. The 577 customer letter will be mailed pending NHTSA approval. Oshkosh does not distribute vehicles through dealers so no dealer notifications are necessary. Planned Dealer Notification Date : NR – NR Planned Owner Notification Date : NOV 21, 2022 – NOV 21, 2022 * NR – Not Reported
