Turntable Hoses Inspection
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 chafing occurring on hoses at the rear of the turntable. Chafing can lead to
hose rupture and the loss of hydraulic fluid. Investigation determined that improper routing or insufficient
retention allows these hoses to move too low when the boom is at high angles. This allows them to rub
against a cover mounting bracket when the boom is raised or lowered or to contact the corners of the pedestal top plate when the unit is rotated.
Altec has developed a kit to properly secure the hoses to prevent damage, if needed.
Altec requires the hose routing to be inspected on the affected units no later than the next periodic maintenance interval or 60 days from the receipt of this SIL, whichever comes first. Use the Inspection Procedure
beginning on page 2. This inspection is simple and can be completed by a customer in less than 30 minutes.
If the inspection criteria are not met, call 1-877-GO ALTEC (1-877-462-5832) option 1 to order the Hose
Securing Kit, part number 991332766, and any required replacements for damaged hoses. Install the kit
and hoses within 90 days of the receipt of this SIL.
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 $45 for the labor to perform
the inspection, up to $45 for the labor to install the kit, and up to $360 for the labor to replace the hose(s).
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.
