Packer Wiper Blades
These UHMW plastic wiper blades are located on each side of the packer. Adjustment of these wiper
blades may include the use of shims.
Replacing Wiper Blades
To replace the packer wiper blades, do the following:
1. Once the side rails have been removed as part, for example, of an upper wear pad replacement
procedure (see Preparing for Upper Wear Pad Replacement on page 136), take out the old packer
wiper blades with the use of a pliers.
NOTE: If a wiper blade is worn-out, you may add a shim or two instead of replacing it.
2. Insert a new wiper blade on each side of the packer.
The rounded part of the wiper blade must be facing the exterior of the hopper.
3. Adjust the newly installed wiper blades (see Figure 3-257).
Danger!
Do not enter the hopper while the packer is moving.
