6. Check the packer for vertical and horizontal movements. See Testing for Excessive Wear on
page 128 for correct procedure.
If the packer shows vertical or horizontal movement, wear pads need to be replaced. Extensive
wear on the hopper floor also suggests that sliding shoes require immediate replacement (see
Sliding Shoes on page 127).
7. Verify packer panel for knocking noises.
Knocking noises indicate that the Extend proximity switch requires adjustment (see Adjusting
Packer Extend Proximity Switch on page 202). Proper adjustment is necessary to prevent cylinders
from bottoming out under pressure.
8. Make sure that hydraulic cylinders are not leaking internally (resulting in insufficient packing
power). For more information, see Detecting Cylinder Internal Leaks on page 285.
B. Inspecting Packer - Standard Units W/O Loading Arm
To inspect the packer:
1. Check the follower panel hinges and verify that there is no wear on the panel surface (see Figure
3-16).

2. Inspect the scraper (nylon strip) at the bottom of both floating panels (see Figure 3-16). This
nylon strip wipes out dirt every time the packer goes back and forth.
Replace this scraper before it is worn down to the top of its holding screws (see Lower Wear Pad
on page 165).
3. Visually inspect both packer side rails and rollers (see Figure 3-17).
If signs of premature wear are apparent, replace the faulty parts (see Sliding Shoes on page 127,
Follower Panels on page 179, and Rollers on page 190).
