Subject:

Half/Pack® and Half/Pack® (Featuring Odyssey® Controls): Front Head
Manifold Hydraulic Tube Failures and Body Controller Program Update to
Smooth Packer Operation

NOTE: READ THIS BULLETIN IN ITS ENTIRETY BEFORE BEGINNING ANY REPAIR WORK.
Waste Management Half/Pack® and Half/Pack® (featuring Odyssey® Controls) units with a published ship
date between August 1, 2020 and August 20, 2021, can potentially have certain hydraulic tube failures due
to tubes becoming misaligned or insufficient tube clamping force to prevent tube damage from vibration.
This Service Bulletin describes the required corrective action procedure to install the Front Head Tube
Support Clamp. This kit decreases hydraulic tube vibration and reduces the potential for tube movement
within the front head manifold. Reinforcing the 3/4” Hydraulic Tube (354-5571) will prevent the tube from
loosening or breaking at the front head manifold connection point.
Additionally, this Service Bulletin provides instructions to install Spill Plate (035-3764) on the upper front head
enclosure, and hydraulic tube thermal resistant sleeve material has been included at Waste Management’s
request. These sleeves will be installed on the four (4) front head manifold hydraulic tubes.
Lastly, this Service Bulletin includes additional instructions to reference and perform procedures from TSN21-002 for affected Waste Management units.

Compliance
Each Dealer must perform these tasks as outlined in this Service Bulletin for each unit identified
above in the Products Affected section no later than November 30, 2021. The tasks outlined in this
Service Bulletin must be performed by a qualified technician.
Completion of this bulletin will be certified using photographs of each unit and the Task Checklist
found on the last page of this document. Waste Management will upload the signed checklist into
their Compass maintenance system and Heil dealers will upload both the checklist and pictures into
Tavant as they file a warranty claim for each reworked unit. Note to Dealer Warranty Coordinators:
please enter as a Campaign Claim for payment; claims filed as Machine Claims will be rejected. If
Tavant does not allow filing as a Campaign Claim, verify the unit information with the Affected
Population description on page one to ensure that the unit requires completion of this bulletin.
Contact the warranty department at [email protected] if any assistance is needed.
Photos
Note: It is recommended that photos be taken both before and after the repair to document the
original condition of the unit before work was performed but “before” photos do not need to be
included with the warranty claim.
To document the final condition of the unit after the repair, pictures are required showing:
1. The Body Serial Number plate located near the front on the street side of the body
2. Front of body showing tubes from exit of the flap area to the clamps that were added
3. In-cab display showing new program number
Photos will be provided to Waste Management and are required for warranty payment.
Warranty Coverage - Mileage
Heil will pay mileage to help defer dealer cost in completing SB-21-351-WM for Waste Management
units at the rate of $1.50 per mile. Miles are calculated using Google Maps from the dealer’s nearest
location to and from the Waste Management location.
Mileage Calculation Example:
Macqueen Equipment going to WM Madison, WI
Miles to WM: 77 miles x 2 (round trip) = 154 miles
Mileage Paid for Warranty = 154 x $1.50 = $231.00

PREPARING THE UNIT AND WORK AREA

Prior to performing Lock-Out/Tag-Out, make sure to LOWER the arms and forks FULLY DOWN to
the ground or RAISE the arms FULLY UP against the arm stops.
Be certain that all hydraulic pressure has been fully relieved before beginning any hydraulic
rework.
To relieve the hydraulic pressure in the system:
(1) With the engine OFF, turn the ignition switch to the ON position (without starting the engine)
and turn the Pump Switch ON. Then:
(a) Cycle the controls to the arms, forks, tailgate, etc., in all directions. This relieves the
pressure in the cylinders.
(b) Turn the ignition switch to OFF.
Make sure that the unit is in Lock-Out/Tag-Out mode before performing re-work. Refer to and follow
your company’s Lock-Out/Tag-Out policies and procedures. At a minimum, refer to and follow the LockOut/Tag-Out procedure found in your Heil Service Manual. Always wear appropriate Personal Protective
Equipment as required by your employer (but to always include at a minimum, safety glasses and OSHA
approved hard-toed boots) when repairing a unit or performing scheduled maintenance on a unit. Clear
the work area around the unit of all unnecessary people and equipment.

D. Test for Hydraulic Fluid Leaks, Reinstall Upper Front Head Enclosure, and Install Spill
Plate
(1) Take the unit out of Lock-Out/Tag-Out Mode.
(2)

Operate all unit functions. Then put the unit back into Lock-Out/Tag-Out Mode and visually
inspect for leaks. If there are leaks, loosen and re-torque the hydraulic fittings that are leaking
and then repeat the process to check again for leaks. Continue this procedure until there are
no leaks, then check hydraulic oil level and add oil if needed. Contact Technical Services if
leaks continue. DO NOT REUSE THE HYDRAULIC OIL DRAINED FROM THE SYSTEM
DURING DISASSEMBLY. Dispose of used hydraulic fluid in a responsible, approved manner.

(3) Reinstall the upper front head encloser using the six (6) bolts and associated hardware that
was removed in Step 3.A.(3). See Figure 1.

E.

Body Controller Program Update to Smooth Packer Operation
Reference TSN-21-002 to update programming on the body controller. This controller program
update smooths the packer movement when changing direction or stopping (extend to retract or
retract to extend). The smoother action reduces stress on the packer assembly and associated
hydraulic components for longer life.
