Packer Roller Assemblies
Packer rollers need to be replaced when damaged or when showing excessive wear or flat spots. The
procedure outlined below will show you how to remove the first, second and third sets of rollers and
how to replace them.
NOTE: If the packer and the follower panels have been removed from the body for repair or
replacement, you can take advantage of it to check all packer rollers and replace those that are
damaged or worn out.
Replacing Packer Roller Assemblies
NOTE: This task must be performed by 2 people.
To replace the packer roller assemblies:
1. Ensure the parking brake is applied.
2. Start the engine and engage the hydraulic system.
Wait for the air pressure to reach 70 psi before engaging the hydraulic system.
3. Remove the tailgate safety pins (see Figure 3-15) and fully open the tailgate by pressing the
T
AILGATE UP switch on the multiplexed control module (see Figure 3-16).
Keep the T
AILGATE UP switch pressed until the tailgate is fully open.
4. On the packer control station, press the green PACK button to fully extend the packer (see Figure
3-18). When the packer has reached its fully extended position (see Figure 3-19), press the red
E
MERGENCY STOP button to stop the packer (see Figure 3-20).
5. Proceed with the tagout/lockout procedure. Refer to “Locking Out and Tagging Out the
Vehicle” on page 20.
6. Place the tailgate safety prop in service position (see Figure 3-7).
Danger!
Never enter the hopper or body while the packer is moving.
