TURBOCHARGER GP 7C5846 - Caterpillar

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.
Before carrying out arc welding on the machine or on any equipment attached to the machine, disconnect all power and ground leads from the batteries in order to avoid possible damage to electronic components.
Welding Requirements
Welding quality is critical to the success of the installation procedures. Welds must be smooth and continuous. Do not undercut the welds. No overlap is allowed. Grind the ends of the welds to a smooth radius.Prepare the metal for welding according to the next section. Refer to the illustrations in this special instruction for welding symbols and specifications.All electrodes must be dried completely. The electrodes can be dried by heating the electrodes to 300°C (572°F). The electrodes must be dried for at least 30 minutes.Do not weld in windy conditions. Do not weld when temperatures are below 16°C (60°F).Penetration characteristics may vary greatly depending on the following conditions:
Electrode diameter
Shielding gas
Welding current
Plate thicknessThe following items also affect the welds:
Geometry of welded joints
Surface conditions
Composition of the base metal and of the electrodeA root pass should be applied before each weld is finished.Maintain a 3 mm (0.12 inch) minimum root opening on all cross welds and circle welds.For more welding information, consult the Caterpillar Service Welding Guide, SEBD0512.Preparing the Metal for Welding
All grease, paint, and foreign objects 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 foreign objects with a wire brush, a buffer, or a grinder. Shot blasting the appropriate areas will also remove foreign material.Remove any oil or grease with a Caterpillar approved solvent.Note: After welding, allow all areas to cool to room temperature. After the areas have cooled, paint the area with primer. After the primer has dried, coat the area with Caterpillar 4C-4200 Yellow Paint.Required Parts

Updating ECM Settings: Reference the following description for selecting the proper "Quick Coupler Configuration". There are either one or two parameters to update, depending on the machine software and system installed.
Parameter: "Quick Coupler Installation Status" (ET) "Quick Coupler" (Monitor)
Not Installed: "Quick Coupler" control system is not installed on the machine.
Installed without Coupler Accelerator: This setting is the traditional North American setting that only applies voltage to the coupler valve when the switch is flipped. This setting is used with the "Center Lock" pin grabber, and new ISO CAT pin grabber couplers. This setting
