Refer to Disassembly and Assembly, KENR8727, "795F AC and 795F AC XQ Off-Highway Truck Machine Systems" to remove all four resistor elements and the intake screen.
Personal injury or death can occur from heavy components falling during removal or installation.Properly support the component with a suitable lifting device during removal or installation.
In order to prevent damage to Electric Retarder, use proper lifting device to support during removal process.
With the grid assembly still laying with the 293-2208 Electric Retarder Gp down, locate and remove the bottom five mounting bolts. Then, locate and remove the existing weld nuts on the inside of the Grid Fan Support Structure. Use a grinder to remove the paint and any remaining weld material around the existing hole.Note: Removal of the five mounting bolts will allow the 293-2208 Electric Retarder Gp to become unsupported by the Grid Support Structure.

Personal injury or death can result from fumes, gases and ultraviolet rays from the weld arc.Welding can cause fumes, burn skin and produce ultraviolet rays.Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing area. Wear eye, ear and body protection before working.Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death.Read and understand the manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts.
Do not ground the welder to electrical components such as the ECM or sensors. Improper grounding can cause damage to the drive train bearings, hydraulic components, electrical components, and other components.Clamp the ground cable from the welder to the component that will be welded. Place the clamp as close as possible to the weld. This will help reduce the possibility of damage.
Insert the new 8T-5911 Weld Nuts into each of five holes with the smaller diameter in the recessed area of the hole. Assure that the weld nut
