Cummins ISX


The Cummins ISX is a I-6 (straight 6) diesel engine manufactured by Cummins for heavy duty applications—primarily: Class-8 over the road trucks (long-haul), Class-8 over the road day-cab trucks, heavy duty vocational trucks, and motor coaches.


Originally, the ISX was called the “Signature” series.


The ISX is available in power ranges from 430 hp to 620 hp (2050 lb-ft).  (A few specialty  models of the ISX engine fall outside that range.)


There is a off-road version called QSX; which is used for industrial, marine, and other off-road applications.  (Cummins manufactures a limited number of speciality engines in this series.)


In 2001, EPA regulations made the Cummins N14 engine obsolete.  The ISX is Cummins’ replacement for the N14.


From 2001 until 2010, the ISX had a Dual OverHead Cam (DOHC), with one cam for intake and exhaust and the other cam for high-pressure, mechanical injectors.  This was called High Pressure Injection (HPI).  The HPI system had a one piece valve cover made of plastic (chrome plated steel on older models).  This system had a separate, low-pressure fuel feed system—called the Integrated Fuel System Module (IFSM).


In 2002, Cummins added cooled Exhaust Gas Recirculation (EGR) which takes exhaust gas and recirculates it back into the intake of the engine lowering the combustion chamber temperatures—limiting the formation of NOx.


In 2008, Cummins added a Diesel Particulate Filter (DPF) which traps the particulate matter (soot) produced in the engine. The ISX uses a Diesel Oxidation Catalyst (DOC) to oxidize the soot, and covert the soot to ash in a process called regeneration.


In 2010, Cummins changed the ISX DOHC to a Single OverHead Cam (SOHC) by eliminating the cam used for HPI.  The high-pressure, mechanical injectors were replaced with a common-rail-fuel-system.  With common-rail-fuel-systems, the fuel is pressurized up to 35,000 psi, and stored in the rail until needed.  High pressure solenoids control the flow of fuel to the injectors.


Also in 2010, the ISX was changed to a Diesel Exhaust Fluid (DEF) system.  With a DEF system, DEF (urea and water) is heated, then pumped into a decomposition tube, which reacts with exhaust reducing NOx.


Cummins ISX Overhaul Kits

Rebuild Kit

There are two basic different kinds of rebuilds: in-frame and overhaul (out-of-frame).



An in-frame rebuild does not require the engine be removed from the truck.  An In-frame kit does not contain all the gaskets for an overhaul, only the parts necessary for an in-frame rebuild.


OVERHAUL (Out-of-Frame)

An overhaul requires the engine to be removed from the truck.  An Overhaul Kit comes complete with all the gaskets for an overhaul..


Prices Single OverHead Cam (SOHC) with pistons:

In-Frame Kit:  ~$3,200

Overhaul Kit:  ~$3,600


Prices Single OverHead Cam (SOHC) without pistons:

In-Frame Kit:  ~$1,800

Overhaul Kit:  ~$2,200


Prices Dual OverHead Cam (DOHC) with pistons:

In-Frame Kit:  ~$2,700

Overhaul Kit:  ~$3,100


Prices Dual OverHead Cam (DOHC) without pistons:

In-Frame Kit:  ~$1,500

Overhaul Kit:  ~$1,900

Buying each part separately -vs- Buying a kit

It will cost almost twice as much to buy an entire rebuild kit one-piece-at-a-time -vs- buying a complete kit.  Add to that the aggravation of ordering every little piece one-piece-at-a-time—and the possibility of forgetting to order something—there is little reason to try to save a few dollars by ordering each piece separately.


If you are a professional mechanic, and you rebuild dozens of of these engines each year—there could be a good reason to keep a few extra parts.  If you are only rebuilding one engine, everything you need is in the kit.


Kits come boxed, sorted, and ready to go.


A lot of parts need to be removed in order to do a rebuild.  Make a list of all the little issues that your truck needs, but you have been putting off.  Discuss these items with your mechanic before you start.  While your mechanic has everything apart, it might be a good time to do a few of those deferred repairs.  Any part that needs to be removed or disconnected is a good candidate for replacement/repair.


When you get the engine apart, you might find that there are other issues.  Be prepared to discuss additional repairs and service with your mechanic.

One piston

If an engine has only one bad piston, it is possible to repair that engine by removing the head and replacing that one faulty part.  Or replacing the piston, bearings, etc of that one bad cylinder.  Then the head could be replaced and everything bolted back together.  This could, potentially, fix your engine’s problem—and save some money today.  However, if an additional problem were to develop or there are other undetected issues—you would have to take the engine apart a second time.  Each time you hire a mechanic to tear an engine down, there are labor costs.


You need to balance the potential short-term savings of only repairing/replacing the parts that are in immediate need of repair -vs- long term costs of having a mechanic disassemble your engine a second time.


Also, there are hidden operational costs in having a truck out-of-service a second time (or multiple times).

Things to think about

When you have repairs done to your truck, you should always very carefully keep the packing lists and repair records.  You never know what small piece of paper will be important years after the repair is finished.  You don’t necessarily need a fancy system of keeping records—just keep the papers in a file-folder, or stuffed into a large envelope.
