+Ching Zen-hua That's probably because the people who work on your diesels where you're from probably lack the engineering expertise needed to understand how to properly utilize and maintain turbocharged diesel engines. If turbochargers were so unreliable,then why does most of the world's major industrial engines pretty much only use turbocharged diesel engines anymore? Most modern diesel engine manufacturers don't even build non turbocharged diesel engines anymore except in smaller sized applications such as with certain specific compact car models,and even many of these cars today usually run turbochargers. Turbocharging technology has made quite a few leaps and bounds over the past decade or so.
I use to Dyno test to maximum load, hot set the valves and injectors, Make any necessary repairs, and rate up to 6 of these newly manufactured engines 5 days a week at the Cummins Engine plant in N.Charleston, SC None of them smoked as much as this engine. The max smoke that was allowed for a new engine then was 1% of the total emission. This one would have failed miserably. I'm also sure that some truck drivers really appreciated some of the engines I adjusted to 450 HP while staying within the established emissions control standards of the time
It’s not a new engine though, it’s not even a reman engine it’s a rebuild at a tech school. Who knows how many hours it has or how many times it was taken apart.
I was fooled too. I thought it was a CAT engine myself until I saw the comment and looked back 😂 added too much yellow paint. Need to be red or cream 🤔

im in wyotech for heavy duty diesels , we had to rebuild a dead engine. we had to tear it down to the crank ,and all of the engines that ran had to hooked to the vent system
The reason is there is very Lil knowledge in there but 2 teachers that's Wyotech heavy duty diesel that's where I went to school what sucks I paid 30000 grad for a name that ain't worth shit anymore cause of shit like this lmfao
I'm not a Diesel expert but I noticed it was cranking quite fast. Is that a lack of compression or a really good starter with plenty of volts powering it?

@@cs-gj3yf a cummins 855 takes more time than what would usually be considered normal for the oil to reach the bearings within the turbocharger. A characteristic design of this type of engine. Not a bad design...just something to keep in mind If you look closely you can see the impeller kinda sticking there towards the end. Also the engine is sucking in its own exhaust gasses....which are inert gasses. This would make the engine run poorly at low rpm.
I am offered a Crown Bus with 855 Series Cummins mid-engine Pancake diesel with a 3-stage Jake Brake, 10 speed manual transmission with overdrive. What concerns me though is, are there enough mechanics out there they can handle a engine like this if I need them, also is it even powerful enough to go places, I mean all kind of places, without an hinge or should I stay away, I myself have no experience with engines.
Here is what I don't get, they don't make these engines anymore or most any mechanical engines. (Other than small engines) So they should be working on electronic fuel injected engines and common rail engines. Then if they want to continue as a diesel mechanic they can learn the old school stuff too. But for now if you go into a truck garage 99% of the trucks that come in are newer electronic engines.
madsexymanofthenight I know man the only thing that those car companies have done is make everything electronic which is a royal P-I-T-A it's a shame that they only make the small 2-stroke diesels now

I drove a Volvo daycab for a year and it had a 525 N14 cummins in it. Awesome motor. But I'd take a 3406 mechanical 425 horse CAT anytime over that engine. Some guys are still running those old CAT motors because they are just the pinnacle in reliability.

I've never rebuilt a diesel, I've rebuilt turbo cars, before but seeing how diesels rely heavily on the turbo, At first start after a rebuild shouldn't you maybe check and double check that the turbo isn't dry and that it's getting oil? I swear I heard that one seize up at the end.
Tubo diesels don't need boost at low rpm or coasting the if they disconnect the turbo it would run fine. The turbo comes into use at high load situations without it it would role coal like a bitch. That's because the turbo crams more air into the cylinder to burn with the diesel
+12DUDE20ONE I'm well aware of that. Turbo'd car engines work the very same way. They all serve the purpose of more power under load feeding the engine more air. I worded my question badly. I was essentially asking, wouldn't normally after you rebuild want to double check the turbos oil feed, to assure its getting plenty of oil when you first start it?
lol the trucking company i work at our goal is boost at lower rpm for low end torque, build boost at high rpm also but that's the horsepower side of it, get the low end torque for the hill climbs, only way to do that is boost at low rpm
Dustoff85 they didn't rebuild Idk y they said that all I did in that class was pull a cpl pistons roll out the crank bearings and time it bc u have to use a weird tool called a swinny tool with a dial indicator...baisicly those are leaning tools so why rebuild it with all new parts every week
