Vehicle Information :
Vehicle 1 : 2024-2024 IC Bus CE school bus Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : OTHER Power Train : DIESEL
Descriptive Information : • The suspect population is identified by models equipped with R. H. Sheppard M100P, M110P, HD94P, XD120P, MD83, SD110P, M83P, and M94S model steering
gears.
• The inclusive dates of manufacture were determined by suspect steering gear serial numbers provided by RH Sheppard and production data at Navistar’s vehicle manufacturing plants.
• The vehicles in the suspect population may have been built with steering gears with suspect serial numbers and all other similar vehicles were not.
There are 1,191 CE school buses in the suspect population. Production Dates : JUL 17, 2023 – DEC 14, 2023
VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect :
Description of the Defect : As reported by R. H. Sheppard Co., Inc. in 24E-094, the defect is a steering gear assembled with fewer than the required number of recirculating balls.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : As reported by R. H. Sheppard Co., Inc in 24E-094, a steering gear with fewer than the required number of recirculating balls may bind when loads are applied. In some cases, the balls may align on the same side of the gear’s worm-shaft and concentrated loads may cause the gear’s internal parts to fracture resulting in loss of vehicle steering. Loss of steering increases the
likelihood of a crash. Part 573 Safety Recall Report 24V-089 Page 2 Description of the Cause : As reported by R. H. Sheppard Co., Inc in 24E-094, an error of the steering gear recirculating ball insertion process occurred during assembly. A gap in the rework process allowed for potentially less than the required number of balls to be installed into the gear without detection. Identification of Any Warning
