Packer/Ejector Panel Adjustment - Dover HEIL DuraPack Python Service Manual

PACKER/EJECTOR PANEL ADJUSTMENT

Proper maintenance of the packer panel and ejector panel is important to the overall operation of the unit. Failure to maintain
proper adjustment can affect payload and cause cylinder or structural damage.
A. Retract Stroke
Make this adjustment with the hydraulic system at operating temperature and the engine RPM held at a level to cause the
packer panel to move at its fastest speed during retract. On some units, the fastest packer speed during retract occurs at
engine idle.
1. Adjust the retract proximity switch so the packer panel retract function shuts off and the panel comes to rest two (2)
inches away from the front head. (The outside proximity switch is located on the front head.) Do not let the packer
panel contact the front head. See the Figure below.
2. After the retract stroke is set, cycle the packer panel again. When the panel stops retracting, manually press the
retract button and note the travel left between the packer panel and the front bulkhead. On some units the outside
proximity switch must be disconnected before you manually press the retract button. If the travel is less than 2", repeat
step (1).
B. Extend Stroke
1. Extend the packer panel until the rollers on the packer follower panel stop and rest at the end of the fixed panel guides.
See the Figure below.
2. Adjust the full extend proximity switch (inside proximity switch located on the front head) so the retract portion of the
autopack cycle starts just before the packer panel follower rollers leave the fixed panel guides.
