SEOCONTENT-START

Install Instructions – Aerial Exhaust Vent Plate Tools Required: • Drill bit –1/4 • Marker • Handheld cutoff wheel • Handheld sander and/or handheld angle grinder Parts Required: • 14”x14” Exhaust Vent Plate • STAINLESS STEEL TRUSS TORX SCREW 0.25-20 X 0.75, QTY: 8 • STAINLESS STEEL NUT 0.25-20 SS HEX LOCK, QTY: 8 • STAINLESS STEEL WASHER 0.25 FLAT, QTY: 16 Installation Steps: 1. Raise the aerial device and raise the cab. 2. Locate the exhaust muffler and outlet pipe on the vehicle. It will be located at the front of the body, on the officer’s side, behind the cab. 3. Locate the exhaust access plate on the officer’s side of the vehicle. Remove the access plate. 4. Locate the exhaust U-bend at the top of the muffler. The supplied vent plate will be installed above this exhaust component. An approximate location for the plate is shown below. 5. Remove the top deck plate above the exhaust U-bend. 6. Place vent plate on top of the top deck plate that was removed. Use a marker to mark the location of the eight ¼” holes in the vent plate onto this plate. Use a marker to draw an outline of the vent plate on the top deck plate. The outline should be 14” x 14”. 7. Match-drill the eight marked holes with a ¼” drill bit. 8. Set the vent plate aside. Use a straight-edge to draw a square that is 1” narrower on all sides than the square outlined earlier. This smaller square should be 12” x 12”. 9. Use a cut-off wheel to cutout the 12” x 12” square from the top deck plate. Use a handheld sander and angle grinder to deburr the sharp edges of the cutout. 10. Place vent plate on top of the top deck plate and fasten the two together using the ¼” hardware. Reinstall the top deck plate in its original location.

Part 573 Safety Recall Report 22V-852 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Identification of Any Warning that can Occur : Melted wire loom and/or discolorations/distortions on plastic tanks may precede the failure. Involved Components : Component Name 1 : VERTICAL EXHAUST VENT PLATE Component Description : VERTICAL EXHAUST VENT PLATE Component Part Number : 1134581 Supplier Identification : Component Manufacturer Name : NR Address : NR NR Country : NR Chronology : In late August, E-ONE had a custom aerial in the test process that was required to repeat the same tests multiple times. Near the end of these repeated tests (8+ hours of essentially full engine load) it was identified that a few plastic type items experienced thermal softening effect. An investigation at the testing site concluded that we needed to reject more of the heat created by the exhaust assembly. Due to the custom nature of the product, research was done to determine how many trucks might be affected with similar designs. Thirteen (13) units were identified. On 9/15/2022 the issue was presented to the E-ONE Product Performance Committee. The committee decided that to understand if this was unusual event, or not, three subject trucks would be inspected in the field to see if they had any thermal softening of components. During inspections no affected assemblies were found. On 10/13/2022 the results of the field units were discussed with the E-ONE Product Performance Committee. It was determined to add the vent to related vehicles out of an abundance of caution. On 11/15/2022 REV Group gave approval to proceed with the Recall. Part 573 Safety Recall Report 22V-852 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : An opening will be added to the body top to let the heat out and a protective grate will be added over the opening. The repair will take approximately two (2) hours. E-ONE will provide the necessary components free of charge. E-ONE will compensate the Dealer or Owner for installing the new components. There is no charge to the Dealer or the Owner for this Recall. How Remedy Component Differs from Recalled Component : The diamond plate cavity cover, above the exhaust, has a vented opening. The pattern is added to each custom vehicle. P/N 1134581 will be used for retrofitting purposes. Identify How/When Recall Condition was Corrected in Production : Vents we added to production vehicles starting August 30th, 2022 Recall Schedule : Description of Recall Schedule : 1) Email dealers a copy of the recall approximately 1 week before customers. 2) Mail customers the recall Planned Dealer Notification Date : NOV 28, 2022 – DEC 02, 2022 Planned Owner Notification Date : DEC 05, 2022 – DEC 19, 2022 * NR – Not Reported
