MODELS AFFECTED: TL48 Aerial Devices
SUBJECT: Pedestal Mounting Bolts
Issue:
Terex model TL48 aerial devices, produced from October 2021 through May 2023, may have pedestal to sub-base mounting bolts that will loosen. The loosening of the mounting bolts may cause the bolts to fail. Failure of the mounting bolts could cause the boom to fall which could result in injury or death.
Chronology :
On June 20, 2023, the Terex South Dakota, Inc production team discovered that the wrong bolts and wrong torque may have been used on previously installed machines for attaching the pedestal to sub-base. All in process machines were checked and verified to have the correct bolts and torque. An engineering analysis was completed on August 29, 2023 that determined the lower bolt torque was inadequate. Development of the field fix began at that time. Even though there are no reports of issues, a decision to recall was made on October 12, 2023.

Inspect the head markings of the bolts to determine if they are grade 5 or grade 8 using Figures 2 and 3 below. Figure 1. Area of unit to inspect pedestal to sub-base mounting bolts Cover plates installed Cover plates removed 2 3. Inspect to determine if the pedestal to sub-base mounting bolts are loose. a. The inspection involves a torque check on all pedestal to sub-base mounting bolts using a calibrated torque wrench. b. Any loose pedestal to sub-base mounting bolts are to be retorqued using a calibrated torque wrench. Grade 5 bolts are to be retorqued to 300 ft-lbs and grade 8 bolts to 460 ft-lbs. c. After retorqueing all pedestal to sub-base mounting bolts, apply torque striping across the bolt head and washer to the bolting plate to aid in further visual inspections. d. Store the pedestal base cover plates and mounting hardware in a secure location, such as a body compartment, until Field Service Kit Z1702 is installed. Inform users and operators that the opening in the body floor around the pedestal may be a trip hazard until the cover plates can be reinstalled. 4.
