Removing Cylinder Head Off CAT D8 Dozer
HTML-код
- Опубликовано: 25 дек 2024
- This dozer has had pressure in the coolant system so we pulled the first head and switched it with another one months ago. In one video you could see that pressure was still present. In this video we are pulling the second head to see if it's cracked and investigating further to see what the problem is.

You can tell that engine has been worked on not too many years before this by how easy the bolts came out of the exhaust manifold.
Il suffit que les écrous soient vissés avec de la graisse graphytée... ils ne seront jamais collés!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!......................................
Blessed are they who take things apart and have no "extra" pieces left over when it's put back together
You and your Pop are livin' the life, man. This is so cool!
These two men are very good mechanics. No muss No fuss, just get on with the job. Git'er done!!
If the head isn't cracked, check and see if you don't have a precup that's letting combustion leak into the coolant.You need a special tool to remove the precups, and there will be a small thick steel ring or spacer under the cup. These sometimes get pitted and you will get pressure in the rad from this. Clean or replace pitted ones, and make sure to get the same thickness spacer. Last resort is check for a cracked liner.
That's all right Pop. One day that wooly youngun' will be easing up and down too. The old 8 I ran had a pressure gauge for the cooling system but it was a newer model. Had seems like 3 ranges that went with the same colors on the temp gauge. When it got up it'd spew out a little but never got hot or really lost any coolant. But you had to be rooting hard on a hot day for it to do it. looks like it's got the brackets for ripper teeth on the back of the blade maybe? The green 7'E's had them. Good video too!
Removing that head is a big big job,putting it back on should be bigger job!! Hope you video that also thanks for sharing ;-)
Just rebuilt a Leyland 154 the head was so heavy but we had our grandfather an experienced deisel fitter been doing it for decades so he knew what he was doing
Hi,
And thank you so much for your kind upload of this D8 video.
Take care and good luck on whatever you are going to do.

Thank you for the trip down memory lane, 70's- mid 90's we used to run 15, 22 & 68 A's ive done this so many times with the old man in the middle of a field up to my knees in muck freezing my nads off on a Sunday morning , they were fuckers for cracking heads, they can be welded once I think, your rad looks like it could do with lifting out and jet washing, it may be why she is cracking heads ? oooh just remembered we used to use two screw in eye bolts on the heads with a span set from each to either a scaffold pole so we could dead lift it up and some one shove a plank on the head bolts or shackle to a back hoe . good luck with the old girl please post a vid of her back to life.
Nice video. Does driving that wedge under the head damage the matting surfaces?
Good work
Real men at work here.
Liner Projection is off, time to cut the counterbores
Snap on or cp air tools are perfect on this job
How
How
i know someone who wants an air ratchet for christmas.
How did you determine which head to remove
what part of Texas are yall in?
Do you have any problems finding a head for a 14A?
no
Really nice video!
Sir what is the part # of cylinder head block of d8
hope those wedges didn't put no Grove on surface.
the block could have a crack in one of the cylinders if a different head didn't solve the problem that mean one of the cylinders is bad and you will have to do a liner change
These two " mechanics" are ignorant. Your using an aluminum fuel filter housing to pry against. I was a CAT mechanic for 26 years. There are so many things wrong with this video , that I dont know where to start. USE THE PROPER TOOLS !!
Air tool are for flat rate repair of late model machines. Sometimes you need to feel these old rusty bolts by hand instead of twisting them off with an over powered air tool; who wants the noise of a gas powered compressor rapping away. There is no Cat shop in this country that would work on a machine half the age of this one; let alone this one....
Why wouldn't a CAT dealership work on it? It's a CAT product, I don't see a problem
Caleb Boyett ......I don't understand it either but that's how it is!! Go buy an old machine and find out for yourself.....
Bug Bomb I work at a CAT dealership and we work on plenty of old model equipment, there are "Classic" CAT parts for a reason you know?
Caleb Boyett do y’all stock anything on a cat 977h
@@calebboyett6591 That may be at the dealership you work at. The Cat dealership near me won't work on a D8H that I own. I was told that they have a Cat certified privately owned heavy equipment shop that works on anything older than 1990. The Cat dealership will haul the pre-1990 equipment to that shop, supply all the Cat Classic parts to them then add on 15% to the bill for subcontracting the work out. That dealership also wasn't very helpful in helping me find the right parts either. They flat out told me that I just need to buy a new dozer when I was looking for new o rings for the 2 oil filters. I haven't returned to that dealership since then. May just be a bad parts guy or him having a bad day but I just order all my parts online now so I won't have to drive a 2 hour round trip just to hear a guy complain about having to look something up or order something for me.
What does this guy do just collect these for hobby to tinker with and how many he got all together.?
Nothing like a pisé of wood between the head!!?!?
You guys made me grimace, the way you work. Lack of hoist. Poor disassembly skills. Spilling diesel all over the place.
i think the amount of work these guys do on youtube shows they have the proper skills. why dont you post some videos of your jobs so we can see how bad you are!
Typical douche bag answer. You just suck so bad. Hey dumb fucks. Diesel school. Top of the class. Anything else?
yeah you suck we know it
Doesn't matter you can just wipe down before starting it i like to you do it with non high tech tools
Two-year diesel school, Grants Pass, Or. 1985. Top of the efin class. Nuf said. Why don`t you learn how to work, instead of answering on You-Tube? Caterpillar would be proud of you.
hope you got some air tools for christmas
what is it ? a 2u?
Did you take any mechanics classes?
Find the culprit yet?
+2boredfortv Uneven cylinder sleeve tops is the culprit.
What the hell hand tools??
D-8 heads don’t crack. Just need new caskets in it.
Oh man be careful not to damage the Kaniblic Pins.

old d8s has many blown head issues...
That's why if you see an operator shut one off hot, you fire them on the spot. Keep them full of antifreeze, warm them up before putting them to work, and let them idle for a while to cool them off after working them and you won't have a head issue. We have owned many D8's and haven't had a cracked head. We still own 8 of them
Man y'all couldn't work at a dealer ship. Where is the air power tools. That's cave man working. Great video tho.
D MCCORD they need a cordless impact wrench, like the ingersoll rand W7150
Power tools don't work up here where i am from. we get -40 below zero on the regular in the winter season. good luck starting your compressor in that even, worse with battery tools they aren't a fan of the cold either. best done by hand. my speed doesn't change winter or summer lol
Did not Alvin and the chipmunks repaired CATs!
Why do you look like a GTA V character? lol no offense, just genuinely curious...
Chip and dale repair a bulldozer. ;-)
Wouldnt give u 2 cents for any of those studs to be any good after u pulled that head off like that
U ARE ABSOLUTELY RIGHT THERE IS NOT A MECHANIC IN THE WHOLE BUNCH
Yeah, that was rough as guts. No finesse.
Cv. Merci. D8k

They sound like munchkins !
