By Cynthia Allen


A Cummins L series engine is one type of straight six diesel engines that are being produced and designed by the Cummins. These types of engine are displacing 10 liters. This was being produced in year 1982, referred to as L10. The L10 engine is produced based on its predecessor having 8.3 liters. This has being utilized in many applications. The displacement is 10 liters and is available in various forms.

The forms may include upright, for use in buses and in trucks, horizontal, for use in the under floor of trains and buses, and vertical. L10 is considered to be the very first type that is offered by Cummins as competitive in a bus market. The reason for this is because its earlier productions are very heavy and large. Also, this became a troublesome introduction to a market that have problems in sealing and high oil consumption. Here are the steps on the installation of aftermarket exhausts into the dodge 6.7 Cummins L engine.

Make sure that before touching the engine, it is already cool enough to be touched. This can protect you from getting harmed due to a very high temperature. When touching it, you can make use of gloves or any kinds of cloth to lessen the heat. Then start on removing the passenger side fender. Be sure that it is well removed for gaining access into the V band clamp.

The V band clamp can be found in the exhausts housing of a turbo. V band clamps are the connections to a downpipe. After the removal of fender, cut off the downpipe using either sawzall or hacksaw. This must be done first before a cross member is cut. With this, you can just easily get that downpipe our from truck.

Begin to loosen the clamps from the exhausts. There are hangers being attached into a vehicle frame, so remove these hangers. Remove as well as the factory exhaust along with the instructions. A factory spare tire heat guard is located in a tailpipe section of an exhaust. Cut if off then remove it. An aftermarket will be accommodated with a bigger size after removing it.

Begin the process of installing the new and the improved aftermarket exhaust. Start on attaching the previously taken factory V band to the downpipe. Then add several pieces of straight exhaust pipes until having to reach the muffler into the proper placement. Aftermarket kits usually are being offered along with pipe pieces having labels of 1, 2, 3, etc.

Muffler hanging. The muffler is required to allow an exhaust pipe to just slide inside it in any directions. This step may be considered as difficult to some, so they are suggested to make us of pliers to stretch muffler ends. Looking for a partner is also recommended when you hang the muffler.

Hanging over a tailpipe section and an axle pipe. Be sure to hang well all hangers. Using a penetrating oil is recommended so that the hangers will just easily slide to rubber brushings.

Do the reinstallation of passenger side fender and make that it is reinstalled well. Cranking up the truck. See to it that no rattling sounds are produced when doing this process. There maybe rattling sounds when an exhaust is loosely attached. Do some further testings and check if things are working out.
