2. Inspect the mast (1) and identify the following locations:

   The upper horizontal edge of the top of the mast - The components for the satellite receiver assembly will be mounted on the upper horizontal edge of the top of the mast.

   The cable route, down the mast - The side of the mast for the cable route is determined as either the side of the mast with the cab or without the cab.

   Illustration 11 demonstrates a cable route (5) on the non-cab side of the mast (1).

3. Verify the following items for the selected mounting location and the selected cable route:

   • The components do not interfere with the operation of other equipment.

   • The cables do not extend beyond the electrical specifications for the cables.

   • The cable route does not prevent access to any access panels that are used for servicing.

   • The harnesses are routed and the harnesses can be restrained in a manner that does not create a trip hazard.

   • The components and the cable route are located away from heat sources.

   • The harnesses and components will be protected from mechanical damage.

   • The area is clean around the location of installation for the components and cables.

Preparing the Metal for Welding

All grease, water, paint, rust, dirt, and scale must be removed before welding. Any of these materials will discharge gas which will cause porosity in the weld deposit. Water and rust will cause hydrogen embrittlement. Hydrogen embrittlement causes cracks in the weld deposit.

Remove any oil or grease that is on the material.

Remove paint, rust, dirt, and scale with a wire brush or by buffing or grinding. Shot blasting all work areas can also remove foreign material.

Installing the Mounting System

Note: Welding must be accomplished in accordance with the specifications for welding that are outlined in the Special Instruction, REHS1841, "General Welding Procedures".
