One of the biggest challenges surrounding CARB Compliance is the ability to find accurate up to date information that is specific to the nature of your business.  The best place to find this information is the California Air Resources Board website, but the site is very large and can be a challenge to find specifically what you need since the site covers so many different industries.  Kustom Truck has taken the difficulty out of locating the information and below you will find direct links to various CARB pages that are associated with the EPA Compliance of the On Road regulations.

If you are not able to find the information you need in order to understand what regulations apply to you please contact Kustom Truck and a sales rep will will be able to point you in the right direction.  Please keep in mind that regulations change from time to time and what you may have researched six months ago could already be updated, check the links above prior to starting any compliance jobs.

Now that the 3rd segment of Kustom Truck converts a 1988 Pete 379 to meet the California Air Resources Board compliance through the year 2023 is complete, let’s show what was done.  In the 3rd part we dedicated it solely to the Diesel Particulate Filter (DPF) integration into the chassis since this is such a major part of the project.  Not taking anything away from the engine conversion cause that was a huge hurdle to overcome in itself.  To complete the engine swap to include plumbing and wiring took roughly a weeks worth of labor, no small task.  The most labor intensive was obviously the wiring since the chassis came with a mechanical engine and had to be converted to accept an electronic motor that the cab was able to communicate with for all the necessary engine monitoring functions.  With that said it’s time to detail how the DPF was installed and take you through the process.

First things first a mounting location had to be chosen to house the DPF.  Where to put the large filter assembly that’s roughly 45″ in length? The passenger side step box …

We chose to custom build a step box that would be located on the passenger side of the cab, just below the door and replace the existing factory box.  The inlet comes in the front side of box through 7″ hole

The back side of the new step box was left open so we have easy access to the DPF filter as well as heat transfer and to provide an easy outlet so we can tie back into the factory exhaust system.

Once Kustom Truck bolted the step box back into the existing location of the old box it was time for a mock up of the DPF to make certain fitment and dimensions were adequate with no clearance issues

Now that the custom step box along with the DPF filter are in place it’s time to get to work on plumbing and piping to get the exhaust from the engine and out the exhaust pipes.  The turbo down pipe was first, the pipe runs down the inside of the frame rail and exits just behind the rear leaf spring hanger.

After some carefully placed bends the pipe was ready to be welded up and attached to the inlet of the DPF filter located inside the step box.

The DPF is bolted into place, the plumbing is complete, all exhaust has been custom bent and hooked up

Here is a shot from under the cab so you can see the DPF mounted in the box from the backside.

There was some custom pipe bending that had to take place in order for the DPF outlet to hook up to the factory Y-Pipe in order to make the exhaust fully functional

And finally a few shots of how the project looked once the lid was installed back on the step box.

Only one more phase of the project is left, Part 4.  In the final stage Kustom Truck will show you the conversion as a completed project, only a few loose ends still need to be tied up before we start the truck and take it on the test drive.

Now that is how a DPF should look! Stay tuned Part 4 will come early next week ….

Galindo Construction based out of Walnut Grove, California came to Kustom Truck with a dilemma.  The California Air Resources Board (CARB) recently passed regulations making pre 07′ EPA engines non compliant to run in the state of California.  Since Galindo Construction had a 88′ Peterbilt 379 they either replace the truck (which was in great mechanical working condition) or find a way to upgrade to meet current CARB compliance.  One phone call to Kustom Truck and the problem was solved; upgrade the engine to meet current CARB requirements, better yet meet CARB requirements through 2023.

The 88′ Peterbilt 379 Extended hood came to us with a 3406B model CAT Engine that met CARB compliance through January of 2012.  Behind the CAT engine sat a Fuller RTO-14613 transmission.  Galindo Construction opted for a 07′ platform Cummins ISX with a DPF Filter system rated at 475 HP @ 1650 Torque that would meet CARB compliance though 2023.  Since the old transmission was no longer within torque spec there was also a transmission upgrade in store for the old Pete, a Fuller RTLO-18918B would do the trick.

The Galindo job shows up with the 3406B model CAT engine that was no longer compliant in the state of California … time for an upgrade!

First up is to get the cooling package removed, disconnect all the hoses and lines, drain the necessary fluids and get the engine ready to be pulled

Time to get that old iron outta there and get the engine compartment cleaned up …. Notice the passenger side step box, this is where the KPI DPF interface will be installed in Part 3

Now that the engine compartment has been cleaned up, time for the project to start gong back together

The customer wanted the engine to match the paint code of the red on his truck … so the Cummins ISX was stripped to get ready for a repaint

Stay Tune for Part 2 where we will be installing the 07′ EPA Cummins ISX
