Sliding shoe
Testing for Excessive Wear
To test for excessive wear:
1. Lock out and tag out the vehicle (see Locking Out and Tagging Out the Vehicle on page 12).
2. With a pry bar, try to move the packer vertically (up and down motion) and horizontally (side to
side motion).
It should not move vertically by more than 3 ⁄ 16” and horizontally by more than 1 ⁄ 8”. If
movement is greater than the values indicated above, check for excessive wear on both packer
sliding shoes and on the wear pads under the side rails (see page 56).
Preparing for Sliding Shoe Replacement
Follow this procedure before proceeding with sliding shoe replacement:
1. Start the engine and engage the hydraulic pump.
2. With the joystick, extend the automated arm to get better access to the hopper area.
3. Push the yellow button on the packer control station to fully retract the packer.
4. Turn OFF the hydraulic pump and the engine.
5. Lock out and tag out the vehicle (see Locking Out and Tagging Out the Vehicle on page 12).
6. Go behind the packer and, with a grinder or cutting tools, remove the welds on both sliding shoes
(see Figure 3-37).
Danger!
Secure the area around the path of the automated arm when performing maintenance
or repair.
Danger!
Never enter the hopper while the packer is moving.
