Well, what do you guys think? Did I do ok?? Will it run??

[@Military-Museum-LP]

Of course!

[@Military-Museum-LP]

I think the idea behind the injector tubes curl is to get equal length, maybe?

[@Onemanstrash1]

I know it will run , but I have a question for you. I recently switched content , to myself doing my car (my occupation is bodywork) How do you get anything done while shooting footage of you doing it ? I am finding it to be a royal pain in the butt... editing it , well thats even more of a pain in the butt

mineral sprits is what we used in 1970 to remove the Cosmoline from VWs when they came off the ships from Germany!

[@Military-Museum-LP]

Excellent paint job.

[@dieseJL]

Thanks! Color turned out pretty nice.

[@tdotw77]

22:03 The loops in the injector lines are because they all have to be exactly the same length so injection timing doesn't get messed up. Takes a certain amout of time for each fuel pulse to go through the lines from pump and get to injectors. So if one was longer than others it wouldn't be perfectly injected ontime. Those fuel pumps are the real magic boxes when it comes to these things! How those things shoot exactly where & how much to each cylinder with ignition advances and all, throughout the RPM range, under loads is crazy. Also i like the " basically witch craft" comment about what happens inside a turbo when you were describing it. 😂 I love turbos, especially diesel engine turbos! The Magic box & witch craft makes me happy!👍🏻👌🏻🚜🛠️🔩🔧🛢️💥💨

[@tdotw77]

I don't think you can go wrong with Rotella T-6 after the break-in period. It's not like this is a high reving race engine or something. Maybe even the Rotella T-5 semi-synthetic would be fine too. I don't think the full synthetic oil is absolutely necessary in an engine like this.

[@dieseJL]

Yeah lots of guys are saying just run the t4 since it’s a flat tappet engine 🤷🏻‍♂️

[@ekkarzbastlirny5769]

That's right, the exact reason for this is that diesel, like other liquids, is incompressible only in theory, in reality it compresses by up to one percent at the pressure that is normally injected into the cylinder. With pipes of different lengths, this would be enough to cause such a large inaccuracy in the timing that the engine could be started, but it would not rev up - or in the opposite case, it would practically not be possible to start, because it would only achieve regular operation at higher revolutions. The secondary advantage of this method is that as a spare part it is enough to carry only 1 pipe between the injection pump and the injector - in the event of any malfunction, the spare one simply bends and does not need to be shortened.

[@Military-Museum-LP]

My oil of choice?, Rotella.

[@dieseJL]

Thanks! Yeah he was born with the same disease I have 😬

[@gejanssen3022]

A well deserved smile again. This was a better one then the tractor last year. The reason why the high pressure diesel lines are bent like that, is to make sure that the length of the line is the same, in a way they have all the same pressure-loss/delay.

[@adrianorourke2893]

Also the bend lets them flex with the vibration to stop them cracking.

[@dieseJL]

Thanks! It’s definitely bigger than the tractor lol

[@chadlazarus3586]

Great job on the build. The bends in the injection lines are to make them all the same length.

[@eddygoodwin7089]

I am jealous, I would love to rebuild an old diesel like that. I have an old Oliver tractor with a Waukesha diesel that is stuck we have dumped all sorts of crap in the cylinders trying to free it up. Haven’t spent too much time on it after that. For painting you can use grease on areas you don’t want painted and it just wipes right off.

The reason for the loot and bins in the line is there identical links, so it gets the same amount of your in each shoulder big Ed coming to you from Central City Kentucky. Have a great day.

[@adrianorourke2893]

You finally got there. The older stuff usually isn't compatible with modern oils and coolants. There are companies that make the fluids with the right additives so as to not damage your engines and transmissions. Here in New Zealand I use Penrite products but I don't know what companies over there offer the right products.

Sounded good and even. CTP seemed to provide quality parts. No issues, not even minor. They were sending parts to a guy building a 3306 in a residential garage. 6 months is reasonable deliverable. LOL.

[@dieseJL]

Fair haha, but I did tell them sooner so they had reason to be concerned. Super cool though I hope I get to work with them again soon 👍🏻

[@jazzerbyte]

Injection line loops: so that all lines are the exact same length to maintain the timing relationship cylinder to cylinder.

[@jimmysurfed]

Congratulations ! You stuck with it thru thick and thin, and it fired up nicely !

[@dieseJL]

Thanks!

[@buckethead9861]

Never a doubt

[@olegrumpy4519]

Always have a board that you can place over the air intake, that will shut a runaway engine down. that is the quickest way to stop them in that case.

[@resto_roller]

If you ever want to stop a diesel run away, get yourself a Co2 fire extinguisher. Very effective, more so than the block of wood as you could have an intake gasket leak which will still suck air and keep it running.

[@jorgesaavedra9158]

That was great. Great content. 👍🏻

[@dieseJL]

Thanks! 👍

[@patrickhile1019]

What kind of crazy brake-in does this need!? My last rebuild was an International DT466 and the break-in procedure for seating the rings, in my opinion was impossible without a dyno. It was something like 75% load and cycle the cooling fan half a dozen times as soon as possible no idioling or messing about. Start it check for leaks and smash on it!

[@ashleywallis4138]

You should be proud you yourself Tyler, brilliant can't wait for the follow up fitting in to the crawler No

[@MegaDirtyberty]

Fricken ae!, you have done it, Tyler. Always a good feeling when you have rebuilt something to hear it run again.

[@dieseJL]

It is, after I get over the nerves haha

[@russwabuda1556]

ty, the bends are in the lines to make them all the same length. unlike electricity, the pulse of the fuel takes a calculated time to arrive at the injectors. if the lines were at different lengths, the timing would be different at each cylinder.

[@russwabuda1556]

do you have goose bumps? i do. so good, so real, so really good.

[@dieseJL]

I was just really nervous lol

[@morgansword]

Nice work and satisfying to watch ..... Mind boggling yet doable for you... even a career should times change and college doesn't go the direction that you studied for.

[@jazzerbyte]

Thanks to Costex - sounds like a solid runner! "Past nap time" - did he sleep through all that noise? One alternate trick I've heard to prevent a runaway is a block of wood over the air intake. Verifying the fuel shutoff as you did is the best though.

[@dieseJL]

He did, somehow. I guess I insulated the garage pretty well hahahaha

[@ShainAndrews]

21:50 Timing loops. Each line needs to be the same length/volume to minimize timing variation between injectors. Now before somebody says you can't compress a liquid... there is a boat load of entrained air. There is a boat load of surface area of the line that deflects for each injection event. Uniformity improves engine performance.

[@jaygee999]

WHAT GOOD DAD YOU ARE, TYLER ! --- The paint job you did is boss ! -- That timing fixture is armed robbery (without a gun) Thanks For Another Great Video ! SHE SOUNDS SWEET !!

[@dieseJL]

Thanks!

[@geofferyshanen7758]

I googled the loop in the injector lines. Just as I thought it’s to absorb engine vibrations and movement. Thanks for your content, I love your video content. Thanks Tyler!!

[@ShainAndrews]

Equal distance for all lines means the timing is correct for all cylinders. If you think through your theory you have to explain cylinders 4-6.

[@dieseJL]

Thanks for the support!!

Injection lines need to be all the same length that's why the short ones have the bends

[@johnbullwinkle4111]

Love it you did a great job. And your not a expert huh must think on that need 🔥.

[@technicalitems731]

Coincidently I've been working on my caterpillar d6d 4x series with a 3306 turbo DI. Wonderful engines. The small block Chevy of diesel equipment engines. Parts sources worldwide! Costex/CTP, china, usa, Italy, and beyond.

[@dieseJL]

Yeah the parts availability is amazing. This one was precombustion

[@rasungod0]

the loops in some lines are for length matching. If some lines were longer than others the pressure would be different and the injectors might not fire from low pressure or fail from too high pressure.

[@Vic-td7hp]

Water is the best coolant.

[@weird1600]

the bends in the lines are to ensure that they are all the same length!

[@Falconurbex]

They put bends in the line because of the pressure they bend and flex and may fracture if its just a single straight line so hence the bend ie the loop it gives them more strength when under operation

[@cullen9017]

I usually deal with Michigan turbo. They do good work, fair price and usually have everything quick.

[@dieseJL]

Aren’t they on the west side?

[@jimedwards9310]

Hell yeah :)

[@denissavoie4123]

Injection lines are all the same length so the ones closest to the pump would be looped.

[@peterduffy3871]

My humble opinion on oil, CAT DEO. I won’t run anything but CAT oil in any of my CAT equipment. I’ve had some not so pleasant experiences with other oils. Great job on the rebuild. 👍

[@dieseJL]

Thanks!

[@user-pi8us8dp3b]

I have watched plenty of your videos thus I offer the following.... Raise the fuel tank above the engine. The engines I have seen you work on do not have lift pumps. They put the tank at or above the level of the high pressure pump and in this case especially you are expecting a pump that PUSHES to SUCK. and that is not the same. In this case you may have started at the bleed screw on the filter and fill it from the top down. I can not stress enough that pulling fluid is not pushing fluid and any air between the pump and injectors stops all flow. cheers. you are great mechanic and raising another one too. Bless you for taking your son to the shop and working with him on an engine NOT sitting in the house watching TV and the net. Keep him away from iphone as long as you can. The net is not on your side when it comes to raising a kid. Go Detroit

[@dieseJL]

Yeah I fussed with it for way longer than I would like to admit before I got the lift pump out lol. But thanks! And the only way I get to work is if he’s with me in the garage or napping hahaha

[@thesmallenginekid]

The high pressure fuel lines on mechanically injected engines are bent so they are all the same length. If they were different lengths the timing would be off.

[@dieseJL]

I see that. But later models are not so I’m not sure what it up 🤷🏻‍♂️

[@eddiezackery4819]

I would run the T4 Rotella is small for the older engine was flat tap it cams. The T6 synthetic is for the modern roller game engines. Just my opinion big Ed coming to you from Central City Kentucky. Have a great day.

[@dieseJL]

That’s what I will run then 👍🏻

[@Vic-td7hp]

Mobil ran synthetic in a diesel truck for 100,000 miles without changing it (decades ago), no wear.

[@anthonywilson2346]

Hi. Basically the turbo is an axial flow jet engine - only different- the hot end drives the cold end - (the compressor) 😮🇬🇧

[@ShainAndrews]

Are we to ignore the fact the fluid does not flow axially?

[@varoonsingh1111]

Use white spirits to clean off cosmoline.

[@jjseibert]

What all did you do to the engine for it to take nine months. I started on a 955L with a cracked head, pulled the engine and tore it down to the block. New complete head, six power packs, water pump, exhaust manifold, turbo, and bearings. On the afternoon of day 6 had it back in the loader and running.

[@ericwhittaker8191]

The fuel lines are all the same length so the closer to the pump they will be bent more.

[@user-fx3dq9cb4u]

How u going to pick it up u barley got it picked up in pieces before sounds great

[@dieseJL]

That’s a great question. Maybe I’ll buy a forklift or something

[@sergueiothonucci1638]

😃😃😃

[@Blast357]

i used to put only the most expensive oil in my vehicules and i realised couple year ago that i should use only what the manufacturer called for. these Cat engine can do 15-20k hours on regular mineral oil... not saying full synthetic isnt better. im saying, are you planning to do 15k hours on this engine? there is a big difference in price in regular vs full synthetic. cannot even bring the point "regular driving vs race driving"... these engines were meant to run full throttle all day long hehehe.
