The high-efficiency weld metal transfer eliminates electrode overheating.Įxhaust manifold repair is easy, time-saving, and money-saving when you use our useful kit. Meanwhile, the 77 rods are crack-resistant, with no need to pre-heat or cool in any special way. The flux coating doesn’t arc even after being heated.

The 72 has extra nickel content to ensure crack resistance and anchors into heat-affected exhaust manifolds. The quantity depends on the diameter that you select:ĥ/32: 2 rods 77 electrode, 2 rods 72 electrodeģ/32: 3 rods 77 electrode, 3 rods 72 electrodeġ/8: 2 rods 77 electrode, 2 rods 72 electrode The Cast Iron Exhaust Manifold Repair Kit includes both 72 and 77 electrodes.
Exhaust manifold how to#
Take a look at our video on how to weld a cast iron exhaust manifold using 72 and 77 rods. You can make this type of repair with a very small welder and still fix exhaust manifolds for a variety of vehicles, including cars, RVs, trucks, buses, and more. Let it cool naturally and even try to keep it out of the wind if possible to allow it to cool slowly. The 77 rods are softer than nickel rods, allowing them to stretch up to 300 percent more to prevent the base metal and weld from cracking.Īfter using the 77 to finish off your exhaust manifold repair, you can simply let it cool and you will have a stronger finish on your repair. The specially-designed coating converts impurities into slag. The 77 is crack-resistant, high strength, and porosity-free. After sealing the crack with the 72 rod, you can chip off the slag and then use the 77 rod to finish it off and reinforce it. If you have dirty cast iron that you need to weld, the 72 rod is ideal for bonding to the metal with its high porosity.
Exhaust manifold cracked#
It’s formulated to join contaminated and heat-affected cast iron, making it ideal for burnt and cracked exhaust manifolds. Kubota Exhaust Manifold Bobcat Part Number: 6599139 This part replaces 1959260C1 Local Store Availability. To repair your exhaust manifold, start with the 72 rods. These qualities make this the kit ideal to have on the road with you if you’re trucking, driving in your RV, or just traveling anywhere and want to make good time. There is no special heating or cooling required when using these rods, and no need to disassemble your exhaust manifold to make your repairs. This kit provides an affordable alternative to repairing an exhaust manifold that could save you hundreds of dollars. If you can reach the crack that you want to repair, you can fix it while the manifold is still in place. Using our repair kit, you can weld the manifold to make your repairs without having to remove it first. Also, in the world of high performance vehicles, tubular exhaust manifolds are called headers – and we’ve got the “header gaskets” to fit.The Muggy Weld Cast Iron Exhaust Manifold Repair Kit saves you time and money on exhaust manifold repair. Whether the application is a late model import or a classic muscle car – Victor Reinz has the right exhaust manifold gasket for you. Because Victor Reinz has a long heritage of supplying gaskets to original equipment manufacturers, we are uniquely qualified to provide MLS gaskets and other constructions that meet OE specifications on a wide range of vehicles going back decades. Exhaust Manifold Gaskets: Modern Materials for All Vehicles.Įxhaust manifold gasket technology has evolved immensely over the years, from the earliest fiber gaskets to graphite to today’s multi-layered steel (MLS). Victor Reinz exhaust manifold gaskets deliver peak performance in these tough conditions. And as manifold flanges warp in these extreme conditions, you need a gasket that can help keep things sealed. Exhaust manifold gaskets must withstand temperatures of up to 1400° F-and be able to stand up to wear and tear between manifolds and cylinder heads.
