Caterpillar part # 367-3070
Just wanted to say thanks for getting me interested in heavy duty diesel repair, I recently started an apprenticeship program with Cummins and I have been loving every minute of it!
Bad choice, I hear those engines are 'reliable'. You should be a Cat guy, as you can tell Josh has plenty of stuff to fix every single day 🤣🤣🤣
Those screws are from a C11/13/15 IVA solenoids. They are the "shipping" screws 🙂
The two pin connector, IVA, Engine Compression Brake, Injector, Cat makes a splice harness. As I dislike cutting wires, I try first is to remove the plastic part of the connector. Most of the time I just break it off. I then inspect the terminals and usually you can respring them as they get flat. So I push it back up and make it tight. I take a old IVA solenoid and push it onto the terminal and verify the connection is snug. Once I know the harness is good, I take the Cat splice harness, take it apart. Throw the wires away and take the connector and install it over the factory harness. If you like the little seal, Cat does sell it separately.
ole c7 you are a patient man at this point in your career. mind your biscuits and life is gravy
we have a special tool we use to remove c7-9 injectors its basically two long bolts that have allen heads in them(smaller than the injector bolts), two nuts that have some flat metal welded to the bottom of them that it folded upwards so you can hold it. The bolts go through the bolt holes on the injector and locate in the head. The nuts go beneath the injector mounts and you can easily unwind and pull out the injectors with a ratchet or allen key.
I made a fork that goes around the injector body under the hold down strap that attaches to a small slide hammer. It’s quick and easy to get them out.
Right tool for the right job. I have used them many times.
i always liked HEUI systems over traditional, its built in safety is if you have a base engine problem low oil pressure, or clogged filter or similar, a HEUI truck will shut down typically before your core is destroyed or major damage is done making what you have still salvageable or perfectly fine if its a small issue, vs normal common rail it will run without Oil usually. or low oil and destroy itself without much warning maybe a dash light, i like HEUI systems as well for the fact they're not as susceptible to poor fuel quality or even contaminated fuel as a common rail system yes you could break some injectors overtime, but you have only so many high pressure oil lines and injectors and the pressures of this system are far far lower than a high pressure fuel pump say a CP3 or CP4, and in most cases when a CP3 or CP4 pump fail all your downstream fuel componets are generally taken with it, with a HEUI system HPOP fails catastrophically which is unlikely since it gets plenty of lube it lives in engine oil, you endup with a system although has quirks once overcome i think far outlive common rail counterparts with less mind paid to fuel quality and just normal oil changes granted oil change intervals on HEUI engines should be MUCH lower than common rail but its a practice i think everyone should do instead of todays OTR trucks doing 25,000 miles plus on a single oil change seen guys doing 80,000 mile oil change intervals on new equipment.
At our shop, we have two allen head screws the same size as your injector hold down bolts and two L brackets with a nut attached to them. We essentially use the two bolts to thread down through those nuts in the L brackets and down into the cylinder head to pry up on the injector. And place the L brackets on top of the injector to evenly press the injector for installation. Hope this makes sense? Can send you a picture if you’re more interested.
Channels like yours are the reason I love youtube. Thank you for all this amazing content.
3:54 MAGIC!...man this channel keeps on giving
Love my skoolie with a 3126b been able to do all work on it myself thanks to you
Stiction is the term for the static friction that you need to overcome to get stuff moving. Its super important to have low stiction on high performance motorcycle forks.
Ain't that the truth about 'quick' disconnects!!! LOL😂 so true, more of a pain that anything. WOW!!! That picture of that gear train made me want to cry!! HEUI's are awesome for their simplicity and are definitely reliable. The metal contamination was an unfortunate, but a failure that has happened for sure. From one tech to the next that loves turning wrenches on anything and everything, thank you for sharing! Always enjoy your videos man! 👍👍💪✌😀
I have spent lots of time working on C-7s on Blue Bird school buses.
I have a puller for heui injectors and it works great . It only takes 3 seconds to pull out a injector.
Thank you 🙏 so much, need this for my bus 🚌
Love the sound bite from an episode of Farscape when Creighton is on a dying Leviathan. 😁
Love your videos man.
Use a small u-bolt through the intake side of the hold down bracket with the threads facing up. Bolt a metal plate across the u-bolt and pry up on the u-bolt pushing down on the rocker shaft.
As always..... great video. 👍
Had a buddy make a custom slide hammer attachment that worked pretty good on the injectors with enough head clearance. It completely ruined the old injector in the process but saved a lot of time
The screws go to a VVA solenoid and were removed after install , thanks for the video !!
I do diesel parts warranty, in my system the 10r8899 pump is just labeled oil pump. Pretty cool to see that it's the HEUI pump. I see those fairly often
You put out great content
I welded a slide hammer rod onto the adjustment screw for a vice grip. Obviously with the hammer on it beforehand. And I think if your able to clamp the vice grip on somewhere of the injector, you can get it out. But you need room above it.
I used the CAT tool when I worked for cat to remove the injectors. Its a little peice of all threaded rod with a nut that kinda jacks the injector out. But it strips the threads after a few sets of injectors. If I can find the part# on my MAC mini prybar I'll post it. I spent 6 years in the truck shop on c7 and 3126's
Hey josh.
Hello from isreal😁
In my experience with the c-7 i found that the best way to remove them is a peice of rope and a long pry bar.
You tie the rope to a circle and then you "choke" the injactor.
You slide the pry bar in the remaining rope, put one side on a high level peice of metal... hold the other side firmly and give it a good 'smack' up. (Like a c saw)
It takes about 3 minutes to pull all six...
Let me know what you think..
Thank you for your videos! You rock🤟
Thanks for sharing
On a trip, bumped into one of your fans in west Memphis, Arkansas. Yep there is such a place. He said he watched you regularly and enjoyed your videos. Another Cat/Adept Ape fan!
That's cool, usually I joke to my wife "theres my biggest fans" whenever I'm at a hardware store next to the ceiling fans. I think she is getting tired of it lol. Thanks for watching Larry.
@@AdeptApe Funny…from nowheresville Oklahoma.
I’ve found if you rotate the injector, sneak a heel bar under the hold down and on top of the head bolt. They pry out fairly easy
Ha josh those 4 little screws look like there from the round cap on top of an injector🤷♂️ love ya vids, there hairs fine as winter is on its way and you may need the extra thatch to keep warm😂👍
I laughed the entire time u were trying to remove the injectors and saying they are the hardest to remove. That's exactly wat I say evertime I have to change c7 injectors.
I have a pair of injector removal pry bars that I think were intended for Detroit injectors. I wonder if they would work for popping those injectors out. I don't remember when or where I got them. I think they are snap-on.
DOTW has definitely improved, may need some more flames or flying parts
VVA solenoids screws. Holds the solenoids together before install. Or those are the install screws as the are two sizes. Depending on serial number prefix.
Stiction might be the word for that bound up friction ( which is measuring moving resistance)

Thanks for always leaving nice comments Nick.
I always pulled the valve cover base and replaced the harness. Seems like any heat cycling on that harness and the plastic turns to dust. It also makes removing stubborn injectors easier with longer pry bars and such. Are you using the new line with the check valve in the kit?
My own homemade tool for those particularly asshole-ish injectors: If they are trash to begin with I have a small pulley puller over the injector head, held the fingers loosely in place with a zip tie, with a small slide hammer welded to the other end of the puller. A bit butch but they always pop right out after the 2nd or 3rd pop of the slide hammer and nothing gets hurt. If the injector you're pulling doesn't have a whole lot of flange depth for the puller fingers to bite a hose clamp over the puller fingers works like a champ too
For injector puller…. Have a small plate witb holes that matches top plate on the injector with a nut welded to it, small slide hammer threads into nut. If you’re replacing injectors completely it works good. Never had the balls to reuse
Slide hammer with special homemade fitting on top injecter
Też bym użył.Ale problem sie robi gdy jest brak przestrzeni nad wtryskiwaczem. Ale można próbować ze ściągaczem typu trawers
I have used a small gear puller with bolts threaded though the injector hold down clamp on both sides and a slide hammer.
Were the first generation HEUI systems less problematic? Like the ones that used the same injectors as the early DT466E, T444E/PowerStroke, 3126
Another Good video. I have a completed skoolie with a 2004 C7. Any suggestions for after the winter
being parked for 4 months spring start up ?
i do enjoy watching all of your videos, i would like to ask if you can do a video about HEUI pump vs Common rail please
on the injector extraction, i am assuming the hold down bracket is the safest location for applying force. If you made an adaptor for a slide hammer to go through that backet. that could possibly speed things up. and insure a good removal angle.
No room on the back 3 cylinders for a slide hammer. The cowl is in the way
works great !
Small screws are shipping screws for IVA solenoids. Two per unit.
You said "front butt" right at 12:29 🤣🤣🤣🤣
Could you loosen the 2 injector bolts a couple of turns, disconnect the injector wiring loom and turn the starter key to turn the engine a few revolutions? Maybe try it off camera in case it goes wrong.
Could the first injector be difficult because of suction in the oil or fuel system or is that not possible?
Internet troll answer to your question of "what do these screws go to" = YOUR MOM :) - great channel keep the vids coming.
Hey thanks I really enjoyed watching your video over the past couple years but I’m also wondering could you do a video on the caterpillar 1693 injectors and turbo
I've been waiting 3 weeks now for the oil feed line for a Marine C7.. not sure why it's special but it was coming from Japan.
Thanks for this video - very helpful. Did you make the install video part 2? Can't seem to find it.
You could probably make a slide hammer attachment for pulling those injectors
A question, wouldn't this be the time to add the Huey Pump filtration kit?
Thanks for doing these videos. I own an RV with a C7 and have really enjoyed your videos and they have really made me much more comfortable working on this engine and helped with PM knowledge.
It's called a Cat oil filter 🤣🤣🤣
@@MacPoop actually over time it is possible for the heui pump to receive unfiltered oil
I used to put a socket under the hold down and use my pry bar and they are not easy to remove either way those are a pain
We have bad parts problem also, waiting for a DPF sensor set for 4 weeks (C7S) Yes, I still have 5 .
What was the solvent mix you were using would like to make or get some.
Thanks
If the injectors are in the cylinder would cranking the engine over with them unplugged and hold downs loose help? Ford designed spark plug automatic change intervals and put a safety hood just in case.
Now I'm replacing my o-rings on my and as far as the placement of the o-rings. The kit came with 1 o-ring that is green. And you can see in your video that that o-ring goes at the top of the injector next to the square o-ring and I'm wondering is that correct?
I was definitely taught to pull fail plugs first and Evac all the huei oil first before pulling injectors. And as for pulling the injectors I use a heel bar with the base pushing off from whichever head bolt is closest and or a socket underneath. I also dip the inj and orings in 15-40 first.
The tiny screws to the IVA solenoids on a C15 acert
For preventative measures, would it be alright to use LiquiMoly diesel purge in a Cat C7? Not sure how the Heui pump would react to it but but I heard it's effective for other diesel engines.
Question.......
The o-ring issue, loosing huei oil pressure, is that a problem on the 3126 as well?
Also..... I have a 3126 the has an issue starting, Allison auto, 2001 C6500 Kodiak/Topkick, 26,000 GVW. Engine was swapped from a 2000 F650 w/Allison.
Recently it started this flutter, missing, weird thing at steady speeds, it also will yield white smoke if you let it continue. If you back out of the throttle or mash it to the floor it stops doing it and runs fine. Also it idles and starts great. The other day I decided I would make a run with it 75 miles away to pick up a Ram 1500. Now this truck is not my normal truck, it's driven by a part time driver, and she had only noticed the weird fluttery miss. So, as I was getting to my p/u the flutter became much deeper pitched and it would start loosing speed and RPM. Back out of the throttle and it would be fine for awhile. Also when the engine was swapped (about 7500 miles ago) I installed mechanical oil pressure 40psi at idle and temp guage 170 degree F. Normal and never seen it get over 200F. I've had people guess all kinds of different things, but if I listen to them and they are not CAT mechanics, it would be torn down to the pistons and rings, just to find out the the injector o-rings or the valves are hanging up or way out of adjustment.
That's what I was thinking before I hit the like button.. 😂😂
Make a grab end (if necessary) for a slide hammer to pull those injectors.
It seems to me that a tool that incorporates a slide hammer with a fork would be good for the injectors. But lift up on the injector evenly should make it easier, because just lifting up on one side can cause more binding on the other side.
Caterpillar part#367-3070 - C7 / C9 injector removal install tool - best tool for inject removal
Going to check out that part number on SIS on Monday.
Strap and a bar works
3:19 *laughs in ISO 16028 hydraulic quick connects*
What about making an adapter that would screw into the top of the injector connected to a slide hammer. That would seem easier to pull the injectors, especially if you work on those engines all the time like you do.
the little bolts are from a 10R 7302 ACTUATOR SOLENOIDS KIT ON C-15
The solenoid that mounts on top of the fuel injectors
All my Thomas C2’s in my district all have Cummins 6.7 ISB engines. Kind of sad not even a single one of them use the C7😢😢😢
Do your screws go to intake actuators?
Looks like the screws for the intake valve actuator
Were those screws to the injector spool valve coil retaining screws?
hi try to use two pry bars to get the injectors out . one pry bar on each side . then you push the injector upwarts ,
insteadt of using one bar and push the injector to the side and not upwarts .
Intake actuator screws when there new need to remove when installed
What would cause extended cranking b4 it starts ? Sometimes it fires right up other times its crank crank and crank only when its sat over night. Once warmed up it starts right up.
Did you ever get your issue solved ? What did the magic trick ??
intake actuator I know there on the C13's and C15's
so Josh I ran a regen on a straight truck with a b6.7 cummins and I believe it's got a blown egr cooler. regen took 1 hr and 15 mins. now the egr codes are gone?? could it have been a failing egr that plugged the dpf so quickly???
and why did the egr codes go away after I ran the regn???
Need to check the cross drilling in the intake air connector. Are you loosing coolant? If you suspect the egr is leaking remove the cross over pipe and take a look. If it is leaking I've seen those things lock up engines via hydro lock. What code was set?
Those look to be the screws that holds the Cat brake solenoid to the Cat brake.
What did the wait time on parts end up being?
I'm just starting to learn and this may sound silly, but can you show the tool you used to suck the grime out? How does that tool work? What do you flush it with, does it need to be totally dry after? I just can't tell if its a compressor set up or a ball you squeeze
Vacuum brake bleeder, just google it, has many applications
Compressor setup brake vacuum, like for disc brakes.
I save one screw, and when I remove a solenoid, I place one in it. So when it comes off it is assembled and not risk dropping the darn thing into a engine and falling apart.
IVA/VVA solenoid shipping screws
Solenoid screws sir?
So if it was a smaller bus would it be "baby huey"?
top of the injector
IVA solenoid screws
Tiny screws are for vva solenoids on a c15 accert
You are correct.
Screws are from injector solenoids of a c7 or c9
Solenoid screws?
😎👍
Those small screws look like the screws I removed from the Iva solenoids on a c13 that keep them together and falling apart during shipping
You are correct.
Joshua those infact are IVA solenoid screws.
Those little screws are from an IVA solenoid aren't they?
Is there a part 2 of this?
