Installation
This manual is used for installation on the VBX and
Forge spreaders. Illustrations may vary .
Determine the left and right sides of the machine from
the normal operating position.
Note: Use pipe tape on all threaded connections.
Installing the Frame Rails
and T ank
1. Park your vehicle on a level surface, engage the
parking brake, shut of f the engine, and remove
the keys.
2. Disconnect the spreader power/ground cable
from the wire harness.
3. Use a 500 kg (1/2 ton) minimum lifting device to
raise the spreader and place it on jack stands;
refer to your spreader Owner ’ s Manual for the
location of the lift points.
4. Remove the spinner assembly; refer to your
spreader Owner ’ s Manual .
5. Remove the rear cover according to your
spreader:
•For VBX spreaders, remove the plastic clips
securing the rear cover to the hopper ( Figure
1).

6. Carefully pull away the rear cover and unplug
the cover harness from the control module.
7. Slide both the long and short frame rails under
the legs of the spreader ( Figure 3 ). If you are
installing the kit onto a VBX 6500 or Forge 1.0
spreader , you do not need the short frame rails.
If installing the kit onto a VBX spreader , use the
wide L-brackets for the hopper legs closest to
the pre-wet tank.
