4.
Check out for leaks on hydraulic hoses and tubes.
Tighten leaking connections and/or replace defective hoses.
5.
Verify cylinder rods:
5 a.
Make sure that cylinder rod ends are clear of debris.
5 b.
Make sure that cylinder rods have no scratches that may cause the cylinder to leak oil.
Should you find oil leaks, the cylinder must be replaced immediately.
I
MPORTANT
:
During the warranty period, do not attempt to change cylinder seals and packing.
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.
C. Inspecting Packer - Co-Mingle Units W/ 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 - 18).
