Units Affected: Units mounted on Aluminum Bodies having Pillow Block Style Body Door
Hinges (Verify that your unit serial number is affected by reviewing the attached list in this SIL
or by accessing your fleet on connect.altec.com/login)
Body Door Hinge Corrosion
Altec is committed to providing our customers safe and reliable products from initial delivery
throughout the useful life of the machine.
Some customers have reported difficulty opening and closing doors or box lids on aluminum
bodies. This has included doors or box lids popping or requiring excessive force when being
opened and closed. Certain bodies are equipped with doors or box lids that contain aluminum
hinge rods going through metal hinges that are manufactured from a different metal. Under some
conditions the hinges can stick or seize due to salt solutions that damage the protective coating
of the aluminum hinge rod. If the hinge rod seizes, it can cause damage to the hinge, door, or
box lid.
To protect the hinge rod from being damaged and seizing, clean the hinge rod
and apply a corrosion inhibitor lubricant. LPS 3 Rust Inhibitor, Altec part number 970293161, (refer to Figure 1) has been found in Altec testing to provide the
longest corrosion protection. A checklist and lubrication process is provided on
page 2. Include this in the Preventive Maintenance and Inspection Checklist for
future use.
This repair is not covered under the Altec Warranty Policy. Call 1-877-GO ALTEC (1-877-462-5832) to schedule the work to be done by an Altec service
technician.
