PACKER/EJECTOR CYLINDERS PREVENTIVE MAINTENANCE
It is critical to follow the guidelines of the Body Preventive Maintenance Chart and Body Lubrication Guide found in this
section of this Service Manual and the Body Lubrication Guide decal on the unit. Failure to follow stated routine preventive
maintenance can lead to premature cylinder failure that is not covered by your warranty.
WARNING
Make sure that the unit is in Lock-Out/Tag-Out mode before you perform maintenance/service procedures, or when you
enter or climb on the hopper/body/related assemblies. Equipment is operational when the unit is not in Lock-Out/Tag-Out
mode. Equipment operated while you do maintenance or service procedures can cause serious injury or death so also
make sure to clear the area around the unit of all bystanders.
CAUTION
Failure to follow these instructions can result in damage to the Heil body, truck chassis or can cause personal injury!
HEIL PACKER/EJECTOR CYLINDERS PREVENTIVE MAINTENANCE CHART
Using a plastic bladed shovel,
clean behind the packer panel
and pockets around sphericals.
DO NOT damage cylinder rods by
striking with any metal object.
Visually inspect that lube lines (if
equipped) are connected and not
damaged or leaking.
Visually inspect packer tracks and
hopper floor for excessive wear
or damage. Repair or replace if
necessary.
Grease Packer/Ejector
cylinder spherical
bearings/pins
Inspect packer/ejector
cylinder bearings/pins
(both ends) for wear, rust
or damage and replace if
necessary.
Perform the operational “Checks and
Inspections” found in the Operation
Manual. If unit recalibration is required,
refer to Cylinder Sensors / Arc Sensor
Calibration in Service Manual.
Side Loading and Premature Cylinder Failure can be caused by:
Inadequate greasing intervals
o causing increased friction at spherical bearings
o potentially resulting in seizing of spherical bearings
Packing into the second stage of a multistage cylinder
Binding of components caused by debris (see figure to right)
PACKER/EJECTOR PANEL ADJUSTMENT
Follow this procedure and refer to the figure below to adjust the Packer/Ejector for Autopack units.
Failure to maintain proper adjustment may affect payloads and/or cause structural damage to the unit.
Packer/Ejector Panel adjustment may be needed when the arc sensor for the packer is changed or is needed to be re-
calibrated. Calibration should be performed ONLY by authorized service personnel. See Cylinder Sensors / Arc Sensor
Calibration for more information.
