Mounting Frame Inspection, Units with Non-Steel Bodies
Altec is committed to providing our customers with safe and reliable products from initial delivery
throughout the useful life of the unit.
Some customers have reported a crack in the side plate of the mounting frame on some units. Altec has
developed a kit to reinforce the mounting frame and prevent cracking in the side plate as well as prevent
further damage if cracking has already occurred.
Altec requires that each unit be inspected for cracking in the mounting frame side plate no later
than the next periodic maintenance interval. Use Inspection Procedure A beginning on page 2.
Altec requires the kit to be installed within one year of the inspection if the side plate has no cracking or
within 90 days of the inspection if the side plate is partially cracked. If the side plate is fully cracked, the
unit must be taken out of service until the kit is installed. Call 1-877-GO ALTEC (1-877-462-5832) option
1 to order the Mounting Frame Reinforcement Kit, part number 991333793.
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. All welds must be applied by a welder having the AWS
D1.1 3G qualification for steel. An Altec Mobile Service technician can perform this inspection but is not
able to perform this repair. Altec will perform the repair 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 $45 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 at
the owner’s location.

Inspection Procedure A
Normal mechanic’s hand tools, a flashlight, and a wire brush are required for this inspection. Read and
understand all steps of the instructions before beginning the procedure.
1. 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.
2. Find the mounting frame under the vehicle (refer
to Figure 1). The initial area to inspect is
the narrow section at the rear portion of the side
plate on the street side of the mounting frame.
Use a wire brush to remove any paint and rust
from this area.
3. Using a flashlight, inspect the outer surface and the upper and lower rounded corners of the
narrow section of the side plate for the extent of any cracking in the steel plate, as defined
below.
• No cracking means no visible cracking at all in the plate.
• Partial cracking means a visible crack anywhere in the narrow section that extends only part
way across the width or part way through the thickness of the plate (refer to Figure 2).
• Full cracking means a visible crack across the full width of the narrow section extending
through the full thickness of the plate and causing the complete separation of the material
(refer to Figure 3).

mounting frame (refer to Figure 4).
3. Using a flashlight, inspect the outer surface
and the rounded corners of the three corners
of the mounting frame as shown in Figure
5 for the extent of any cracking in the steel
plate.
• If there is no cracking in any of these three
areas, order the kit as specified on page 1
