3606 start-up after rebuild without rocker covers. see also a movie about the latest overhauled Niigate engine roughly the same type. • Niigata 6L28HX start a...
I just love those that old school Mechanical Fuel Injection. No electronics to run it no Multi fueling cycles just 3 lobes on the cam intake fuel & exhaust. Mechanical engineering at its finest.
this engine was rebuilded in the workshop, and then transported to the dyno, then loaded on a truck. transported to norway where it was reinstalled. so to take the lifting eyes of so many times is a bit over the top. yes after installation onboard they where removed so that the head studs could flex. on the dyno the nuts where loosened. happy now?
The plunger that is pumping the fuel has a spiral groove in the side of it. The spiral groove is in alignment with a port in the barrel of the pumping mechanism. By rotating the plunger in the barrel, the spiral groove passes the "spill port" at a different position of the pump's stroke. There is a control rack that turns a gear on the plunger to control the amount of fuel delivered. The engine can have different options for a governor.
Yes the push rods and valve stamps are lubricated by a channel in the rocker and this is lubricated by oil comming out of the rockershaft. Oil is still cold during the filming engine is just started.
yes, you can pull one head, one liner, and one piston, I have done it way too many times lol. Almost all of the larger diesels have individual heads and inspection covers that allow you to pull power packs individually. These you also have the stretch the rods to get the nuts for the heads and main bearings off. They are pretty cool to work on
(continued) There is a linkage inside the engine that connects the control racks of all injectors to a common shaft. That shaft is connected to the engine's governor actuator. One type governor monitors the engine speed electronically and others use centrifugal force. Either way the governor is moving the linkage and therefore all injectors' control racks.
No problem! I'm also a Caterpillar Marine service tech (like the owner of this video) and these engines are my passion. This system is safer in a marine environment, becuase there are no high-pressure fuel lines to burst and create a fuel mist in the ships engine room. All the high pressure is contained within the injector. There is a set of linkages inside the engine that moves a control rack in each injector to control the amount of fuel.
first we removed all cover to check that there was lubrication, all OK. When we where installing them we decided to make a film about it so we left the last 2 off and started the engine again just for the fun but the lubrication was fine.
@mrcobus86 cat 3600 series is my favourite engine , the electronic version of this has come. Anyway are you working with cat dealership too? just to have some exchange.
As far as marine engines go they are quite a young design, only been around 20 years or so, and the early ones, at least the industrials, were troublesome, luckily the crankcase openings are big enough to get a shovel in to clean out the trashed rod bearings.
Is that true that you can rebuild a cylinder one a the time on those kind of engine? I'm a truck mecanic so I have never seen those kind of engines on trucks.
Without rocker covers, I'd think that oil would spray everywhere... Does this engine not pump oil up there? If so, how are the rockers and valve stems lubricated?
hahahahahahaha i find it hilarious that you say that because caterpillar 3600 series engines are actually the most reliable marine diesels on the market! they are very well built and very well engineered.
Normally I'd agree, but these are meant to stay on, you would have to change the head studs if you wanted to take it off. New MTU's are the same lifting gear is permanent fit, makes sure the engine is lifted from the correct place.
Hola buenas noches después de un top end de un cat 3606 la unidad a quedado trabajando pero con temperatura de refrigeración altas 200 °mi pregunta es cual podría ser el problema
What rpm is that running at? Did you have the oil supply hooked up? Haha cool video. I take care of a couple g3616 TA's tried to remove a cover at 900 rpm. Did't take long to realize I wouldn't have seen anything but oil spray onto the 500 degree exh manifold !!!
the engine ran 300 or 350 low idle with small throttle up to 400 rpm. yes prior to start we prelubed the engine with a standby pump. engine is relatively cold as we just run it for 15 minutes to check the crankshaft bearing temperatures.
I commented on this a few months ago.. I received an answer. He said because this engine was just started, oil had not reached up there yet. It was still cold.
The CI of a 3606 is 6,773.. The 3600's were the biggest engines Cat made while my dad worked there in the 80's to early 90's. Here's the spec sheet: img.nauticexpo.com/pdf/repository_ne/19997/cat-3606-propulsion-spec-sheets-52923_1b.jpg

oh and by the way it's a four valve head. the rocker arm presses a valve bridge which then presses the valves.

It`s 1 of 2 engines from a tugboat.
There is quiet a big turbo on it. it runs with 34 psi boost

Man, that CAT sounds like an ALCo 244! =D

Is it ME have integrated LO tank sir or still need separate LO tank from doublebottom and pump?
lol this is because all caterpillar engines have a signature sound that sounds great when they run!
@mrcobus86 cat 3600 series is my favourite engine , the electronic version of this has come. Anyway are you working with cat dealership too? just to have some exchange.
runs good like a Cat should, I dyno them at the factory where 3600s are made.
Listen to that kitty purr.... Love it.
Third rocker operates the fuel injector. Each injector is it's own fuel injection pump, and that middle rocker powers it.
just a test run or warm up for dyno? awesome sound, even better than pielstick

Thats pretty interesting. How is the fuel metered?
sounds like a cross between a alco/ge locomotive and an non turbo emd
Is that true that you can rebuild a cylinder one a the time on those kind of engine? I'm a truck mecanic so I have never seen those kind of engines on trucks.
you wouldnt happen to have a vid that shows more of the testcell? specially the engine testbed... taylor dyno?
2 valves, the one in the middle is the injector! Nice engine, beautifull sound! :-D
whats that thing installed in if its using an Air starter? Boat? Sounds naturaly asperated too.
left is for the exhaust valves, middle for the unit injector(so fuel pump and nozzle in one) and right the intake valve.
Without rocker covers, I'd think that oil would spray everywhere... Does this engine not pump oil up there?
If so, how are the rockers and valve stems lubricated?
What happens to them rocker plates if they dont go back excactly wher the came from?
3 valves per cylinder or the middle is for the injector?
the 2 outer rockers are for the valves the middle is for the unit injector.
hahahahahahaha i find it hilarious that you say that because caterpillar 3600 series engines are actually the most reliable marine diesels on the market! they are very well built and very well engineered.
yes that is correct I am a Cat Engineer for Pon Power Netherlands.
Why doesn't the oil spill without the head caps?
@87cr250r what makes the engines reputation so bad? just curious.
@jbigbike
Weight aprox : 16 Tons.
Length about 5 meter.
Height 3 meters.
Engine bore 28 cm.
Engine stroke 32 cm.

According to Cat the stud nuts can be removed 13 times before replacing both
and what do you have thats better?
That is so cool, thanks for posting it!
It doesn't really matter whether or not you leave the lifting brackets on or not it doesn't effect the studs
I’d like to see the adjustment of the valve & injectors

Wrong thermostats?
this is my favorite sound clip on youtube
You can even ear the compressed air starter at the begening of the video

wow 350 rpm, mine idle at 700, there is no way I could start one like this without spraying oil everywhere
is this a marine application?

Buenas tardes mencuentro laborando enun generador modelo 3606 cat como puedo regular la inyecsion del actuador o regulador
what is the size of this engine?
Whats tickover and full speed revs.
Wats with the 3 rockers arms?
How big is this motor?
how many cubic inches or liters?
Hotrodx199 it's pretty big they are used on ships as generators, and in railway locomotives

listen to that cat purr...:)
Neat sound! Thanks for posting this!
that thing sounds awesome
@darkskyline95 3000HP or 2240KW@1000rpm. engine torque 22030NM or 16250LB/FT@900rpm
read comments please
4 valves.
2 intake
2 exhaust
middle for fuel injector.
grtz
@JGMagoo thanks, i never thought of that.
The 36 series Cats are not particularly old and are not well know for their durability.
this is warm up before dyno test 1640 Kw @ 950 rpm
very smooth
Nice odd to see 3 rockers per cylinder on a mechanical cat
why three rockers
tzaca-tzaca! long life caterpilar
The 3606 Clatterpillars are good but Id rather have a 12L Series 60 DDEC.
The engine should never be started with the lifting device mounted on the engine.. That is so bad as it can get......
Rockers .... yes ...... more rockers ....... yes ...
middle one is the fuel injector.
excelent engine
thanks for the info
Some more valves noise on this engine.
souns like locomotive
nice
souding perfect
@kennjohnsen correct
i dont
ah ok
*looks at your nick*
“1,245”
“1,238”
Make that "VALVES".
^^ya sarcasm, it's pretty harsh actually. :D
Take the quote from the film Apocolypse Now by Col. Kilgore and sub in "Diesel" instead of "Napalm"...lol
5/5
@mrcobus86 Thats a terrible motor.
Klutuk klutuk klutuk
Hmmm... Okay.
Check mine out @ M/V Mississippi . Great machines
how many hp on it ??
3 Valves?
