Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools in order to perform these functions properly.

Required Tooling
NOTICE |
---|
Keep all parts clean from contaminants. Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components. To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly. Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination. |
The following tooling needs to be used with the hydraulic tank in order to prevent loss of hydraulic fluid:

- Remove the hydraulic tank breather from the hydraulic tank.
- Install the 311-1362 Vacuum Gauge Gp (AA) into the hydraulic tank.
- Attach an air supply hose onto the 311-1362 Vacuum Gauge Gp (AA) .
Apply 138 kPa (20 psi) in order to prevent damage to the hydraulic tank. This procedure will pull a vacuum on the hydraulic system.
Welding Procedure
Personal injury can result from flame cutting or welding on painted areas. The effect of gasses from burned paint is a hazard to the person doing the cutting or welding. Do not flame cut or weld on painted areas. |
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 paint, rust, dirt, and scale with a wire brush or by buffing or grinding.
Remove any oil or grease that is on the machine with a Caterpillar approved solvent.
- Lay out dimension (A) 170 ± 2 mm (7 ± 0.08 inch) from the end of frame support (CC). Lay out dimension (B) 110 ± 2 mm (4 ± 0.08 inch) from the inside edge of the frame support (CC). Lay out dimension (C) 50.8 ± .5 mm (2 ± 0.02 inch) from the center of dimension (B). Center punch the intersection of each dimension in order to locate each boss. See illustration 4.
Use a transfer punch with the same diameter as the internal diameter of the threaded hole in the 4E-3956 Boss (10) in order to center the bosses on the marked locations. The transfer punch helps to hold the boss in place for tack welding.

- Locate a 4E-3956 Boss (10) to the frame. Insert the transfer punch into one of the 4E-3956 Bosses (10). Insert the tip of the transfer punch into the punch mark. Slide the 4E-3956 Boss (10) to the frame. Tack weld the boss in place. Ensure that the boss is square with the frame before any final welding is performed. Repeat this procedure for the second 4E-3956 Boss (10) .
- Ensure that the threaded holes of the 4E-3956 Bosses (10) align with the 141-1481 Shuttle Valve (3) mounting holes.
- Weld around the perimeter of each 4E-3956 Boss (10) with a 3 mm (0.12 inch) fillet weld.
- Clean the area around the welds and paint the area in order to inhibit rust.
