TRYING TO UNSTUCK CAT D7 ENGINE!!!

[@robertlloyd7167]

A buddy and I used to fool around with these old Cats. When we found one stuck, we'd always remove the injector nozzles, pour diesel or Marvel into each cylinder, and let them soak for a day or two. Worked really well.

[@freelancerider100]

Marvel is great stuff

[@fortunateson9040]

It's never easy tow starting an engine . Ive been dragging around my chainsaw all morning and it still won't run

[@357bullfrog2]

Lol!!#

[@Bob-jw1pc]

My son and I freed up a 46a d8 ,,, pulled the injectors and put atf and acetone in each of the cylinders,,,, left it for about 2 weeks and used a long bar on the ring ger\ar to start rocking it,, It broke free after about 3 seperate attempts,,,, now to fire the beasty back up

[@gypsytraders]

best way to free up a stuck engine...these guys here are real idiots. I have used atf and acetone many times...

[@JimNichols]

It is your dozer, your video, your time and you share it .... but I am going to sit here in the A/C and tell you how to do it. .... with a keyboard.... I love KZbin.... live life man, enjoy this everyday you can!

[@JimNichols]

@Tsunauticus III it is as many dots as I wish... so there is three for you. ... as I was saying someone bitches about everything on KZbin. .. and actually there is no ac in my house in Thailand.

@Tsunauticus III what the hell are you a dot nazi ?????????? There are you some question marks to play with ...........and some dots too if that's your thing 😂😂😂

[@Troubleshooter-2.0]

My Grandad used to pull start his D6 a few times with an IH 806. Looked funny but worked like a charm.

[@Wildstar40]

Fill the crankcase right up to the top with diesel fuel and let is soak a day or two, drain, refill with oil then do this. Never try to turn a seized engine dry.

[@beboboymann3823]

Pull the injectors and dump automatic transmission fluid into the cylinders. Leave injectors out for the push.

[@gypsytraders]

@@beboboymann3823 50% atf-50% acetone,....let soak 2-3 hrs and good to go.

[@11secghia]

hand grenade- pull pin,drop, run like hell and never return!

[@mojostevo]

Turn the transmission upside down, shake, fill pistons with cream soda, turn right side up, then wait 4 months.

Man that turbo on the D7 is just music to my ears. I hope y'all get the other D7 unstuck!!!!

Love to see them ole girls still at it!! 👍hope she runs like a top for ya boys!!👍

[@dieselsforlife3847]

I’m not going to tell u boys how to do something but instead tell u how I have gotten lots of old engines unstuck most of the time. Pull injectors out use whatever u want for liquid u want for penetrate and heat up the water in the block to 180 or 200. Then let it cool off. The liquid u put it will get sucked in to the bottom of the pistons and will let loose most of the rust. And whatever water maybe in there will get evaporated out from the heat. Just a suggestion tho.

[@sherischneider2672]

Thanks for posting the best way to break an engine loose on this comment stream. Great idea to heat up the coolant. I haven't heard of that before.

[@alecfranklin522]

I bought a cat d6 9u with a stuck engine and tryed to free it up like this ended up rebuilding the engine then i found out y it had been sitting all those years. The hub that the sproket presses on to was broke ..... I got a good used one and im in the process of putting it back together

[@jefffaubell5271]

Get a 5 gal can of wd-40 and dump it down the stack till it's full, leave sit for a week and get on the flywheel with a nice long bar. If it doesn't move let it sit a little longer and try again. If it moves give it another day and bar it over. I did this on a d82u that had been "rain poisoned", took me about 3 weeks but I got her loose! Good luck and I hope you get it loose.

[@rodbambauer3041]

Ah yes, the sound of a 17A's turbo. Listened to that for years, years ago. Sweet machine with excellent power to weight ratio for it's time. Better than the D7E that were produced concurrently with the later model D7-17As. I agree though, some lube first would be a good idea. You probably did that though. Wonder if a high gear on the 7 would have been better than a low gear...just thinkin. Yes even reverse has multi speeds.

[@wilmamcdermott3065]

U cn pull more than u can push . But u need some fueloil and dextron to soak those pistons and rings

[@marklesperance1129]

Should have added a little lamp oil to each cylinder and let soak for a day or two

[@donaldbartram6315]

That 1st puff of black smoke says it all

[@Okanagan48]

Love that turbo whine.

[@amd65ak47]

Very nice track machines. could use some paint though

[@wilmamcdermott3065]

Tryed pulling it behind a newer d7 just skidded the tracks so soaked it fr three months with dextron acitone every couple weeks through injector holes

[@soupertrooper3864]

[@colonialroofingofnorthcaro441]

Never seen something jumped off backwards lol it worked

[@EL300B]

Love the sound of turbo 17A's.

[@vincentrolfe1384]

Question: was the stuck cylinder machine put in a higher gear to push from or a lower gear and thus too much torque required. Twas pushing a dual wheel truck one time (6 of us pushing forward) and the driver had the trans in low. I yelled "2nd gear" and away we went.

[@ElizabethMcGreevy-j2d]

How do I contact you about using a portion of your video in a nonprofit video?

[@albertcyphers1532]

Why do you not use the throttle when the machine bogs down? Instead you back off, when you get a good push going Throttle It

[@johnpullman3227]

Check out the humming bird that photo bombs at 5:45 into video. We drug an old John Deere Wheatland around the yard twice before I found the decompression lever. Then I got a shower of rusty water which turned into a run away engine. I've never gotten off a tractor so fast as that time in order to shut off the fuel valve.

something will give out and it's not the engine for sure hydrolock ftw

[@1glopz]

Note had the pistons been siezed it would have never started (review the term engine siezed )

[@charlienorton2337]

G Lopez that was a different dozer that started

I get the feeling that an engine as seized as that will need to be torn down.

Did you at least soak the pistons in penetrant oil?

[@DieselPowerTV]

We will soak the pistons with oil or rust eater liquid.

[@donaldhofman296]

My brother in law restored many old diesel Minneapolis Moline tractors that had stuck engines, he put diesel oil in the cylinders and let them soak for a couple of days and most of them freed right up! He has the complete set of Molines !

The D7H has been fixed. I probably won't see the D7H anymore because the person I worked for who owned the D7H has died and every piece of equipment he had will be sold.

You have to know what your doing to operate one of those old machines , I am sure they have done it a time or two .

I am not so sure...they don't know how to free up a stuck engine....what they are doing is stupid.

[@backyardbuilttrucks1]

@@gypsytraders Push or pull starting is common .

[@finndog2759]

Next time buy a head gasket. Remove the head, see why it's set up!! You can do more damage by doing stupid shit like this. If rings and piston set up, pour some sneakin oil in the cylinders. Let set a couple days. Take a 5lb hammer and a block of hard wood. Now tap on the top on the pistons. It will free up, just cool your jets. Once it is free, you can check the cylinders for wear, scratches, broken rings, ect. Lazy people!!!

[@DT-ge8gd]

Apparently none of them know what "throttle" is....

[@RustyorBroken]

I thought the same thing. Lugging that diesel at idle is a great way to have two broke diesels. My dad farmed for decades and ever since I was young he always said that when you're working a diesel there's only one position for the throttle, wide open.

[@courtneyparrish6918]

Yea, since when do you idle DOWN when stalling?

[@rickallen6378]

That is definatley not the way to do that. Those cylinders need to be soaked.

[@DieselPowerTV]

If soaking the cylinders doesn't free up the pistons. Then we can use another parts D7 for a engine swap.
