Service Information Letter SIL- 3052-A
Hydraulic Ball Valve Shutoff Placard
Units Affected: Certain L42/45 M/P units built from February 2002 to November 2019. Verify your unit
is affected by reviewing the attached list or accessing Altec Connect.
Background: Altec has learned that the hydraulic ball valve on the hydraulic reservoir return line may
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.
Customer Action: Order and install the Hydraulic Shutoff Valve Placard Kit, part number 991591189 or
991606176, or schedule the installation of this kit by Altec. Verify the correct kit part number by looking
up the part number on the cover of the unit's Operator's Manual and consulting the table below. The kit
must be installed by the next preventative maintenance interval, or within 90 days of receipt of this notice,
whichever comes first.
Each kit contains placards to update one set of unit manuals. If the unit has multiple sets of manuals, order
as many kits as the unit has sets of manuals.
Subsequent damage from failure to perform the required action(s) in the time period allowed will not be
covered by warranty.

Requirements: Every affected unit requires the installation of the proper kit for completion. This work
is estimated to take 5 to 10 minutes and 1 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 $13.50 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 repair at the owner’s location.
