Build Hydraulic Tanks


 * [1] Cut 1/4"x6"x12" tube for hydraulic tank
 * [2] Cut 1/4"x6"x12" end closures
 * Secure 3 bungs - 3/4" for filler/breather, 1" for return line filter, and 2" for suction strainer (extender plus bung proper)
 * Torch out 3 bung holes as in last step
 * Grind tank edges and bung edges clean wherever bead will be welded. This is a critical step that helps eliminate pinholes after welding.
 * Clean edges and bungs
 * Ream bungs as necessary for cleaning and fit
 * Lay out on welding table
 * Close off bungs with fittings to prevent spatter from destroying threads
 * Tack everything
 * Weld
 * Assemble tank
 * Test hydraulic tank with air pressure and soap solution
 * Plug 3/4" and 1" bungs for air tightness
 * Screw in suction strainer and reducers down to air hose fitting
 * Connect air hose
 * Fill air into suction strainer opening.
 * Grind and weld any pinholes, retest, iterate if needed
 * Assemble return line filter assembly, with thread tape as needed, and screw into side bung of the hydraulic tank.
 * Screw in suction strainer assembly, use thread tape as needed, and reduce suction strainer down to 3/4" NPT hose barb
 * Cut section of 3/4" suction hose
 * Screw in filler/breather cap into top bung.
 * Take off return line filter assembly and filler breather, plug holes, and cover suction hose barb - in preparation for welding to frame.
