Steering Gear Assembled Incorrectly – 2021-2022 Global M4 (M4, R4, M4 HSD) & M4 CNG Sweeper Vehicles

SEOCONTENT-START

A potentially defective steering gear can be identified by a serial number and a part number engraved into the steering gear housing. Perform the following procedure to identify the steering gear serial number and part number. 1. Park the vehicle on a flat surface. 2. Set the transmission to park or neutral and set the parking brake. 3. Ensure the vehicle ignition is turned off. 4. Install the wheel chocks. 5. Unlatch and open the hood to access the steering gear. 6. Locate the steering gear serial number and part number. NOTE: If the serial number or part number cannot be easily read due to paint application, gently scrape the number(s) with a flathead screw driver, wire brush, or emery cloth, or apply acetone. Too much intervention may cause the numbers and letters to be illegible. There are three common styles of engraving locations to be aware of when locating the serial number and part number. NOTE: If you need assistance with locating or deciphering the steering gear serial number and/or part number, email [email protected]. Sending a photograph of the steering gear serial number and part number may be helpful. 7.Record the Vehicle Identification Number (VIN), steering gear serial number, and steering gear part number. 8. Keep record of all inspected steering gears and their status outcomes. Identification Guideline Sheppard™ Steering Gears Identifying Sheppard™ Steering Gears Covered in this Field Action RHS0007 Effective Date: 7/1/22 Interpreting the Serial Number and Part Number: A serial number and part number are engraved into the steering gear housing. See Figure 4 for further information on interpreting the serial number and part number. PART NUMBER EXAMPLE: SD 110 PAU 3 SD stands for “severe duty.” The first characters of the part number represent the steering gear family. 110 indicates the diameter of the piston in mm. 3 indicates the steering gear has automatic relief plungers. Other designators are “1” for manual relief plungers and “2” for special applications. An additional number after “3” indicates there is a pitman arm installed on the steering gear. PAU: The first letter in this sequence will either be “P” to indicate “Power” or “S” to indicate “Slave.” “AU” represents the specific model of the M110 steering gear. PART NUMBERSERIAL NUMBER SERIAL NUMBER EXAMPLE: 21 E 07957 -C 21 represents the year the steering gear was built. E indicates the month the steering gear was built (A = January, B=February, C = March, D = April, E = May, etc.). -C indicates the steering gear has a snap ring style sector cover with a retainer clip. 07957 is the sequential serial number for gears built that month.

Global Environmental Products has decided that a defect exists in certain 2021-2022 M4 (M4, R4, M4 HSD) and M4 CNG sweeper vehicles. The steering gears may have been incorrectly assembled, which can cause the gears to fracture. A fractured steering gear can cause a loss of steering control, increasing the risk of a crash. IMPACTED PRODUCT This recall impacted product is SheppardTM steering gear model M100PTM . Manufactured between Jun1, 2021 and February 10, 22 inclusive. Affected steering gears can be identified by their serial numbers. Please use the attached Identification Guideline document to identify your steering gears. PROBLEM DESCRIPTION Some select street sweepers were sold between 9/10/21 and 8/01/22 may have these recalled steering gears installed. WHAT YOU NEED TO DO Check each sweeper on the inspection list below the steering gear box serial numbers. To identify this Serial number, use the identification guide attached. Send the list of VINS and Serial Numbers to Manuel Hernandez at [email protected]. Once Global has processed your information an email will be sent to the submitter stating if any vehicles have suspected steering gears and the process will began for replacement, free of charge. Sheppard has issued a recall for these steering gears and global will be processing claims for labor and parts. To perform the remedy may require 4-5 hours of downtime.
