Subject:

Half/Pack® and Half/Pack® (Featuring Odyssey® Controls): Front Head
Manifold Hydraulic Tube Failures

NOTE: READ THIS BULLETIN IN ITS ENTIRETY BEFORE BEGINNING ANY REPAIR WORK.
Certain Heil Half/Pack® and Half/Pack® (featuring Odyssey® Controls) units manufactured between October
1, 2018 through July 31, 2020 identified below can potentially have specific hydraulic tube failures due to
tube misalignment and insufficient tube clamping force to prevent tube damage from vibration.
This Service Bulletin describes the required interim corrective action procedure to install the Front Head Tube
Support Clamp Field Kit (372-9225). This kit decreases hydraulic tube vibration and reduces the chance of
front head manifold tube movement. Reinforcing the 3/4” Hydraulic Tube (354-5571) will prevent the tube
from loosening or breaking at the front head manifold.
These procedures are to be performed in conjunction with the procedures detailed in SB 20-333-2.

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. Extend the packer past the side
door to allow access to the front head from inside the body AFTER Lock-Out/Tag-Out has been
performed.
Be certain that all hydraulic pressure has been fully relieved before beginning any hydraulic
rework.
To relief the hydraulic pressure in the system:
(1) When there are in-cab controls, turn the ignition switch to ON then:
(a) Move the switches of the hydraulic controls. This relieves the pressure in the cylinders.
(b) Turn the ignition switch to OFF.
(c) When there are no in-cab controls, move the outside control levers to relieve the pressure
in the cylinders.
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.

Heil Environmental Service Bulletin procedures are intended for use by professional technicians, NOT a “do-it-yourselfer.” They are
written to inform experienced technicians of conditions that may occur on some units, or to provide information that could assist in the
proper servicing of a unit. Properly trained technicians have access to and are familiar with the applicable Heil Operation Manual
and Heil Parts and Service Manuals and have the equipment, tools, safety training, and know-how to do a job properly and safely. If a
condition is described, DO NOT assume that the Bulletin instructions apply to your unit, or that your unit will have that condition. See
your Heil Dealer to determine whether your unit may benefit from the information in this Service Bulletin.
This entire bulletin (and any attachments) is confidential and only for the intended recipient(s). Use or distribution by any unintended
recipient is prohibited. If you have received this bulletin in error, delete this entire communication, and notify the sender you have done
so.
