Dear Altec Owner,
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act, and Canada Motor

Mandatory Action Bulletin
September 3, 2021
Units Affected: D2/3/4000B, D30XXE, and DHXXE Series digger derricks built from December 2020 to
February 2021 (Verify that your unit serial number is affected by reviewing the attached list in this MAB
or by accessing your fleet on connect.altec.com/login).
Service Parts Affected: Part number 970351336 replacement planetary rotation gearboxes purchased from
Altec Parts from October 2020 to February 2021 for use on D2/3/4000B, D30XXE, and DHXXE Series
digger derricks
Rotation Gearbox Brake Inspection
This Mandatory Action Bulletin requires immediate action.
Altec has been notified by its supplier that the retaining ring groove was incorrectly located in the motor
adapter on some planetary rotation gearboxes. Improper location of the groove may cause the retaining
ring to be not fully seated. The retaining ring can become dislodged due to improper seating. If this occurs,
the gearbox brake can no longer hold the boom’s rotational position, which could result in the boom
rotating freely. Death or serious injury will result from uncontrolled boom movement.
This Mandatory Action Bulletin requires immediate inspection of the retaining ring depth in the motor
adapter on affected units and on affected replacement gearboxes. Refer to the Inspection Procedure beginning
on page 2. Nonconforming gearboxes must be removed from service and replaced within 30 days of
the receipt of this MAB.
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 will allow up to $90 for the labor to perform
the inspection and up to $180 for the labor to perform the repair.
Call 1-877-GO ALTEC (1-877-462-5832) option 3 to schedule the work to be done by an Altec Mobile
Service technician or option 2 to schedule the work to be done at an Altec facility. Customers are responsible
for the travel costs of an Altec Mobile Service technician if the technician performs the inspection
and/or repair at the owner’s location.

Inspection Procedure
Normal mechanic’s hand tools and the 3/16” x 2” long dowel pin, part number 991360707, included with
this MAB or a 3/16” drill bit are required for this inspection. Read and understand all steps of the instructions
before beginning the procedure.
1. If the rotation gearbox is installed on a unit, proceed to step 2. If the gearbox is not installed on a unit,
proceed to step 5.
2. Position the unit on a level surface. Apply the parking brake and turn off the engine. Remove the key
from the ignition and secure it. Chock the wheels. Follow your employer’s vehicle lockout/tagout
procedure.
3. Locate the rotation gearbox on the rear of the turntable (refer to Figure 1).
4. Remove the two cap screws and washers retaining the motor to the gearbox. Do not disconnect the
hoses from the motor. Remove the motor and place it next to the gearbox. Keep the fasteners for reuse.
Proceed to step 7.
5. Support the gearbox securely in an upright position (refer to Figure 2).
6. Remove the two cap screws and washers retaining the cover plate and lifting eye to the gearbox. Remove
the cover plate and lifting eye. Keep the removed parts for reuse.
7. Locate the retaining ring in the recess on top of the motor adapter (refer to Figure 3).

8. Place the end of the 3/16” x 2” long dowel pin included with this MAB or the flat end of a 3/16” drill bit
on top of the widest portion of the retaining ring 180 degrees from the gap between the lugs, with the
side of pin or bit against the wall of the internal bore in the motor adapter (refer to Figure 4).
• If the OD of the dowel pin or drill bit overhangs the ID of the retaining ring, the retaining ring is
fully seated (refer to Figure 5). This indicates the gearbox is conforming according to the design
specifications.
• If the ID of the retaining ring extends beyond the OD of the dowel pin or drill bit, the retaining ring
is not fully seated (refer to Figure 6). This indicates the gearbox is nonconforming according to the
design specifications.
