I work on diesels all the time and talking to truckers. As soon as you mention these 855s or 3406a there eyes light up and then get all kinds talkitive. Those 855s are easy to repair and nothing but raw torque.
The vacuum would seal that jug up just fine. A piece of thick rubber would be ideal. No mess from an extinguisher and nothing gets trashed in the turbo like a shirt or hand.
Hmmmm Caterpillar 3500 series diesel engine rebuilding is my real passion. I would like to share initial start up video clip of my own workshop engine after complete overhauling and deep machine work. We replaced exhaust flanges of both manifold along original steel seated exhaust gaskets, high temperature bolts and self lock nuts. Also replaced turbo exhaust housing couplings over size along machine work. So after all hard work nor a single fume if exhaust is leaking as seen resulting optimum turbocharger boost pressure.

@@machinist1337 Its not a cat. It looks yellow like a cat but cummins used to be a beige, cream color before the electric models came out and then they went to red.
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.
Sort of funny to hear my daughter.... an inventory control specialist. For Cummins engines....to talk about older Cummins engines. And newer ones.... the little girl I help raise😊
I actually found a blog where a guy was slamming versatiles and even the 855, then went on to read twenty others that said the opposite. I love my 525 N14, always pulling 90000 up hills past others!
+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'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?
Blue Big Cam NTC and NTE droven 400 hp, NTC little more pover, but also thirsty, NTE less and not so thirsty. Water pumps axle was the weak part. Next aftercooler. Othervice very reliable.
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
Nice to see a pre Obama diesel getting a second life. I have a few of these on generators and a little 4 cyl. version of it on a 50KW Onan, very nice, fix your turbo and keep those old diesels alive!
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 🤔
Yo repare dos motores de estos son muy buenos pero les puse un radiador y los probe todo el dia..un NT 855 Y NTA 855..testeando la presion de aceite y temperaturas....todo ok..
People say exhaust gasket leak, but I think it's the high temp molycot or copaslip which burn and giving smoke. 2ndly don't go for the color of engine, we are the engineers, diesel engine repairing inspects. Bother the color part, color doesn't matter to a engine.
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.
Class of 1986.you are right take apart put back together. I'm still turning wrenches. Not easy trade but you can make good 💰. I Brock 6 figers last year
People commenting about the paint...Manufacturers don’t own colors. I’ve seen red John Deere’s, white Volvo Pentas, white cats and Cummins, Black Yanmars and blue nanni diesels.And a lot of the Cummins in the power gen field are painted green. Some Perkins are black also in the power gen field. Marine applications are typically whiteIndustrial are typically yellowBut i guess it depends on whose holding the rattle can that day lol
@@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.
Looks like a community college HD mechanics class.... they prob don’t even put exhaust gaskets on because this engine gets taken apart and put back together 4 times a year... hence the exhaust leaks. Guys pass the hands-on part of the course if she runs...
+sTEVAL570 ILL GUARANTEE that CAT will outwalk that cummins anyday.Cat has far more torque..and runs cleaner as well.bet youget way better fuel milage as well. CAT RULES CUMMINS DROOLS..LOL
usaisalwaysnumber1 I get better fuel mileage, but he also has a 30+ year old motor...his truck will burn about a quart and a half a week...all motors are great if they're taken care of properly. I've seen shitty CAT, Cummins & Detroit motors, so it's all in the hands of the owner to make sure their equipment is maintained the right way...I'm a CAT guy though, everything I've driven that has a CAT motor, has always been the best available in its respective class. 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. A little cold blooded in the winter, but those motors pull like they do brand new until it's time for a rebuild.
