DOC
Connect the welding ground cable directly to the DOC brackets or the DOC that will be welded. Place the ground cable as close as possible to the weld. This location will reduce the possibility of welding current damage bearings, hydraulic components, electrical components, and ground straps.Note: If electrical components are used as a ground for the welder, current flow from the welder could severely damage the component. Current flow from the welder could also severely damage electrical components that are located between the welder ground and the weld.

Weld blanket
Illustration 6 g06519272
Use a weld blanket draped over the engine to protect the engine from weld splatter. Likely need 2 or 3 blankets to cover between DOCs and the entire engine from splatter.

(1) 536-5400 Plate
Clean the top surface in the two locations where plates (1) will be welded in place with either a wire wheel or a flap disk.Note: Failure to clean the weld area could result in poor weld quality.

Set the plates on the top side of the housing and line up perpendicular to the front face. Position the plates to dimension (D1) from the front edge of the top plate.
Position the plates to dimension (D2) from the far edge of the rounded plate. There is a chamfer and fillet weld that will make measurements less precise. Use a tape measure to position.Note: Etching marks may also be present on the top of the unit and can be used for further positional guidance.

(W1) Tack weld
With the plates in place, add tack welds (W1) to the plates shown in Illustration 12. Use 308L weld wire.
Illustration 13 g06519408
(W2) 50 to 100 mm (1.969 to 3.937 inch)
Skip fillet weld (W2) down the side of each plate and then weld at the ends of each plates. Use 308L weld wire.
