Altec Industries, Inc. has received notification from an Original Equipment Manufacturer (OEM) that a condition exists relating to motor vehicle safety, compliance, or emissions in a vehicle you possess that is equipped with Altec equipment. Navistar has decided that a defect which relates to motor vehicle safety exists in certain 2017 thru 2020 DuraStar and WorkStar model trucks built 01/19/2016 thru 12/20/2019, 2016 and 2017 TranStar model trucks built 12/14/2015 thru 04/12/2016, 2017 thru 2019 ProStar model trucks built 01/13/2016 thru 03/02/2018, 2018 and 2019 LoneStar series trucks built 07/13/2017 thru 02/08/2018, and 2018 and 2019 HC commercial buses built on 08/07/2017 thru 10/25/2018. The Heating, Ventilating, and Air Conditioning (HVAC) system blower motor circuit may have been built with a wire terminal that does not meet the electrical current requirements for the blower motor circuit. This can cause overheating that may melt the plastic material of the fuse block for the HVAC circuit and subsequent damage of the surrounding area of the Power Distribution Module (PDM) and/or dash panels.

Altec has learned that Section 8 of the Maintenance Manual for certain Altec LS60 aerial devices built from November 2017 to January 2023 contains an incorrect torque value of 325 foot-pounds for the rotation gearbox mounting cap screws. All other locations in the manual contain the correct torque value of 150 foot-pounds for these cap screws. Torquing these cap screws to 325 foot-pounds can stretch them, causing loose mounting of the rotation gearbox. The Maintenance Manual has been updated to show the correct torque value. The owner should request updated Maintenance Manuals by November 30, 2023.

Altec has learned that the hydraulic ball valve on the hydraulic reservoir return line of certain L42/45 M/P units built from February 2002 to November 2019 might not get returned to the open position after being turned to the closed position for maintenance. If the upper boom drive system is articulated while the ball valve is in the closed position, both upper boom drive cylinders could retract simultaneously causing the lower boom to buckle. The customer should order and install the Hydraulic Shutoff Valve Placard Kit. The kit must be installed by the next preventative maintenance interval, or within 90 days of receipt of this notice, whichever comes first.

Service Bulletin/Repair Instructions
The body compartment wiring on certain Altec aerial devices, digger derricks, and body-only units built from 2014 to 2021 contains an in-line fuse located close to the lighting in the compartment, while other units are fused upstream, closer to the power source. Altec has learned that the units affected should have an in-line fuse close to the lighting, but this fuse was not installed on some units. In addition, some units may have exposed terminals at the end of certain portions of the wiring in the body. If the exposed terminals contact each other or with ground, the resulting direct short could damage the body compartment lighting. Inspect the body compartment lighting circuit at the unit's next scheduled service interval or within six months of receiving the SIL, whichever comes first. Use the Inspection Procedure or contact Altec to perform the inspection. This inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer's warranty provider. Altec will perform the work for free at an Altec facility. If the customer or the customer's warranty provider performs the work, a warranty claim must be submitted to be reimbursed for the cost of the parts and/or labor.

Altec has learned that the electrohydraulic outrigger/tools control valve on AA755L and A-series aerial devices and DLB, DMB, and D2/3/4000B series digger derricks could have the potential to produce a very small amount of flow into the lower tools circuit when the outriggers and tools mode is engaged. This can cause slow unintended movement of a tool such as a pole puller cylinder that is connected to the tool circuit. A blanking plug must be installed to prevent this issue. Inspect the outrigger/tools control valve using the Inspection Procedure. The inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer's warranty provider. Altec will perform the work for free at an Altec facility.
