Or at least injectors started going bad, but I would need to buy all 6. Other then injectors, they're good solid trucks. Sep 8, We run a lot of dirt roads, farm roads, etc and we're paid by the load.. The Macks are solid for tough work.
I've driven Petes and KW's in the oilfield that were about equal in dependability. Petes and KWs may have a few more creature comforts but I like the Mack too.
One thing is for sure, we don't have a terrible amount of emissions related problems with the MP8. The co. Just a guess, but my guess the Cummins have 10 times the emisions problems as our MP8s.
They handed me the keys to a brand new Pinnacle just a couple months after hiring on and it just topped k in 2 yrs. Its been an awesome truck, still tight and solid for the most part and we run em hard and rough. We have 1 Mack with the Mdrive transmission and all of those IHs came with ultrashifts. There is no comparison. That Mdrive is awesome! Off road, rougher work.. I have no problem recommending Mack because they do have an awesome emissions compliant engine with lots of low end torque and the availability of an awesome auto transmission.
My truck did have 1 injector issue at around k, but none since. Enuff said, unless someone can give me some technical reasons why MP7 worked, and MP8 doesn't, I'll save my words until our next contract renewal. Jon Kaufman Sr.
And while Secure Boot may not have been supported with the Maybe when Jon Kaufman has finished working with his engineering team, he will have all the answers that we seek.
Sorry Jon, no pressure or anything. Our drivers our signed, just not the way that is neede for Secure boot. Please see the following article regarding this issue. Thanks for the link to the article Jon. While this makes it "official" that MP8 will never install on a Win10 machine with Secure Boot enabled, the question still remains as to why MP7 works just fine, but MP8 doesn't. It seem like Symantec would strive to do their best to support their long standing customers Unless there was a technical reason for doing this which so far I've not heard of none then I believe it was a management call to neuter MP8.

Support case created Rising back pressure caused by plugging the exhaust system decreases fuel economy and reduces engine efficiency. It is necessary to clean these filters from time to time. The filters can be regenerated to continue in use. The high temperature needed to complete the process exists in the exhaust itself. For vehicles that produce and maintain adequate exhaust temperature, the soot and ash are consumed at a rate that prevents clogging the filter prematurely.
Setting a DOC ahead of the catalyzed DPF in the exhaust stream reduces the temperature required to regenerate the filters. However, the process is not complete. For vehicles that are unable to develop or sustain adequate temperature, there is more than one system for supplying sufficient heat. An aftertreatment fuel injector AFI Figure 31 , adds fuel to the exhaust stream as it leaves the turbocharger. The temperature of the exhaust at this point is hot enough to ignite the fuel which then produces the temperature required to clean the filters.
If needed, the discharge recirculation valve DRV reroutes some of the turbocharger output back through the turbocharger. This helps to maintain high exhaust temperature. The engine electronic control unit EECU controls the cycle based on information from back pressure sensors in the output stream. As with passive regeneration, the process is not complete. Remove the filters and physically remove the remaining material using the special machine for cleaning. The filters are reusable.
Any time the engine is running and regeneration is not taking place, air is purged through the AFI. Air for system operation is drawn from the chassis secondary air system. The pressure regulator reduces chassis air pressure to the approximately 32 psi level required for the air purge system operation.
The double check valve assembly, which has both air and fuel ports, directs the flow of air and fuel to the AFI while preventing fuel from entering the air system and air from entering the fuel system. This results in elevated exhaust temperature. The exhaust system reaches extremely high temperatures. Ensure that the system components are clear of all combustible materials. Ensure that personnel are aware that the surfaces are extremely hot.
Failure to heed this warning may result in severe personal injury and property damage. Above this temperature, sulfur can become sulfuric acid. These filtering systems are practical only on vehicles that use ultra low sulfur fuels. It is required that diesel engines operating in conjunction with a DPF system use ultra low sulfur fuel that contains 15 parts per million ppm , or less, of sulfur. The exhaust aftertreatment system EATS usually operates in one of five modes.
In the Normal Mode, the engine is controlled by its regular calibration. However, the filters can be self-cleaning through passive regeneration. Heat Mode indicates that active regeneration is in process. In Passive Regeneration Mode, the engine creates sufficient exhaust temperature to convert the gases and regenerate clean the filters. In Active Regeneration Mode, exhaust temperature is artificially raised for short periods of time to convert the gases and clean the filters. The applicable controller reacts to data from back pressure sensors to start and stop the active regeneration process.
A system in Service Mode is being inspected for accumulation of soot and ash in the filters to determine whether they should be manually regenerated or removed for external regeneration. The space saver unit attaches to the outside of the right rail under the cab Figure Either of these connects to the engine exhaust system behind the turbocharger.
Fresh air enters the intake above the back of the cab. Plastic duct work leads the air to the filter assembly mounted on the bulkhead under the hood. An impregnated paper filter prevents foreign particles from passing through. The assembly design permits the addition of a second filter if needed in extreme environments. The brake system air compressor also draws fresh, clean air from this same pipe. Welcome to ManualMachine. We have sent a verification link to to complete your registration.

Lubrication System A gear-type pump at the rear of the engine, driven by the crankshaft gear, draws lubricant from the oil pan and supplies the system. Oil flows from the pump through the distribution housing to the filters, to a gallery at the right side of the engine serving the crankshaft journals, to a gallery at the left side serving piston lubrication OIL PUMP.
