Service Information Letter SIL- 3011-A
Auxiliary Air Compressor Feedback Diode
Units Affected: Certain vehicles equipped with CB5 cranes built from August 2021 to June 2022. Verify
your unit is affected by reviewing the attached list or accessing Altec Connect.
Background: Altec has determined there is a missing diode that allows feedback from the auxiliary air
compressor to the ignition in the affected units. This feedback prevents the engine on the affected units
from being turned off if the auxiliary air compressor switch is in the On position.
Customer Action: Order and install the Feedback Diode Kit, part number 991536080, or schedule the
installation of this kit by Altec. The kit must be installed by the next preventive maintenance interval or
within one year of receipt of this notice, whichever comes first. Subsequent damage from failure to perform the required action(s) in the time period allowed will not be covered by warranty.
Requirements: Every unit requires the installation of the proper kit for completion. This work is estimated to take 20 minutes and one person to complete.
Completion and Warranty: The repair is 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 will allow up to $30.00 for
the labor to perform the repair. Customers are responsible for the travel costs of an Altec Mobile Service
technician if the technician performs the work at the owner’s location.
