- This is how I free stuck Detroit injectors. Check out Old2strokers channel on freeing up stuck injectors as well.: • How to free up stuck 5...

This was a really good video. Nothing better than some WD40 and coffee mix for your daily health. As an industrial mechanic, I can totally relate.
I'm glad you liked the video.:) These injectors are still running nice in the 8V71.:)
I've watched this several times. Totally love how you laid it all out for us. very useful Vid my freind!
Thanks, glad it was helpfull.:) Thanks for watching.:)
Thanks for the update it's been a long time since I have been doing that to a injectors bring back old memories
You're welcome and thanks for watching.:)
Super thankful for your knowledge.
Can’t wait for that ole detroit to run!
You’re welcome, should have Jimmy running in no time.:)
Sure glad you posted this so much help
Thanks again
Your welcome and thanks for watching.:)
Thanks for the film , may be doing this on the 353 , and I'll do as you do , see you in the next episode !
Just finish watching ///// Nicely Done. Thank you!
Your welcome and thanks for watching.:)
Love learning from the best. Nice video!
Thanks.:)
Hey my friend...nice to see your going strong ...keep the videos coming....
Thanks.:)
Hello, this is very helpful for a first timer, thank you
You're welcome and thanks for watching.:)
Your videos have been a lot of help. 453 thanks
I'm glad they're helpful and thanks for watching.:)
You can let them soak in HOT cooking oil on the stove till depressed plungers pop(sometimes an hour) . Even works on stuck hydraulic lifters/ tappets although they're cheap
Thanks I'll try that out next time.:)
I'm going to venture into the depths of this technique and try a injection pump 🤯 see if it helps any. I'll try a turkey fryer and let yall know how it goes...

I'm going to try one of those sonic cleaners on my injectors.
@@brad3378 I've heard they work great, never tried one, but let us know how it worked please.:)
@@detroitgarage9430
Will do!
I actually bought my still-unused sonic cleaner to use on my new resin-based 3D printer (which is also unused). From what I understand, the 3D resin prints are considered Hazmat so they wear gloves and wash off their parts with isopropyl alcohol. Some clever folks in the 3D printer community discovered that they could conserve their expensive alcohol by putting their parts inside zip-lock bags with a small quantity of alcohol while using ordinary tap water (outside of the bag) to fill the rest of the sonic cleaner. I figure it's probably safer too, rather than agitating already aerated flammable solvents.
I'm going to try the same thing with my injectors with an appropriate solvent after I verify that it won't dissolve the ziplock bag. The best part is that my solvent won't be diluted by the water so it shouldn't require much. The bags will pay for themselves in unused hand soap.
Spot on!👊🏻🇺🇸
2Stroke Wayne introduced me to penetrating fluid---Free All--on applications like
bound injectors--dang near miracle fluid
Thanks
id love to see a detroit injector calibration video, thank's for the good video
I would love to have one, but almost impossible to find.:) Maybe someday I just might find one.:) Thanks for watching.:)
@@detroitgarage9430 yeah i guess they are rare but a guy like you could make one maybe with an old head and make the camshaft turn with an electric motor and use some syringe body to calculate the flow per minute. haha yeah it sound's crazy but it might work.
I really enjoy your videos, I have learned a lot. My friend has a Timberjack skidder with a 353, he was coming out of the woods two winters ago and the skidder lost power and quit. He wrapped it up for the winter and finally got back to it. We discovered the emergency stop was tripped,closing off air to the blower and the inlet fuel line to the injectors was blown off. We drained the fuel tank, put in clean fuel , cleaned emergency shut off, put fuel line back on, checked the fuel filter and got fuel up to injectors by turning engine over and bleeding air. We could not get one injector air free, air just kept pissing out. So after many tries, new batteries, good connections, recharging batteries, bleeding air, a little ether, it still just spins over and won't start. (Air in injector closest to skidder operator.) Any help would be greatly appreciated.
You don't really need to bleed Detroit injectors, but instead make sure both the primary and secondary filters are full of fuel and fuel is getting to the filters. Sometimes it take a little work to get the fuel pump primed, but once it is then the engine will start. It will run rough for a minute or so until the air is out of the system. Again confirm the emergency stop is in the open position and the fuel lever is in the run position. One last thing, confirm the rack is free before starting.:) I hope this helps.
What would you recommend as the best injector for a 4-53t marine engine? Looking to get more than 170hp outta them, but without sacrificing reliability. thank you for sharing your knowledge!!
The largest injector I can find for the 53 series is the 5840 that delivers 85-90 cc/1000. A common injector that a lot of 4-53T guys run are the 9A90's and they deliver the same as the 5840. With keel cooling and water jacket intercooling that should give you about 250HP. I'm running 7A77's @ 74-79 CC/1000 and am around 210HP with intercooling.
@@detroitgarage9430 thank you for the advice. How well will it hold up to 9a90's? I don't want to burn em up, but I do want to get more out of them. They do have intercoolers
@@dannyjones3840 I haven't tried the 9A90's, but from the guys I know running them they're fine. I can say for a fact the 7A77's are smoke free and max egt's are 850. I have a set of 9B90's but haven't installed them yet.
Good day..I have a 353t turbo engine which is slow accelerate when pedal is depress. I found the fuel rod to injector rack attachment point is out of alignment. Have to force the rod in place to insert the pin. I suspect a bend fuel rod. Question to you is it ok for me to reform the rod to remove that force?
Yes, I have run into the same problem and repaired the rod so it works correctly. In these cases it's best to run the rack again so it's adjusted properly. Thanks for watching.:)
I see a lot of different “families” of Detroit injectors. What are the differences between them and what are their respective applications?
Too many to list, best to search injectors and download the injector service manual.:)
I have a galion t-500a grader and im looking for the partnumber for the injector...
I posted some injector sizes and the part numbers, if you have a different sized injector let me know.:)
Hello.
I have injectors really stuck in my Jeep Wrangler unlimited with VM diesel.
What is the best most aggressive penetrating oil please?. I'm guessing Kroil?
Common rail injectors run at far tighter tolerances and higher pressures than the old Detroits. You could try Kroil or Archoil AR6200, but they'll probably have to be replaced.
@@detroitgarage9430 Yeah mine are totally seized in rock solid. It's really common with European diesels. The first modern Common rail diesel engine I ever seen was in 1993 on a Italian "Same" Silver ag tractor which was beautiful.
@@conmanumber1 About the only way to fix your issue is to exchange for rebuilt or new. Even if you can free them up, they'll probably not spray right. Did they get def or Adblue in them?
When injectors are stuck for many years, does it do them any harm?
No, as long as they are not rusted. These injectors are stuck from Diesel that's turned to varnish, so no harm done.:)
Hi what is the par number of this injector?
What size of injectors do you have? Here's some parts numbers: N55 is 5228785, N60 5228760, N65 5228900, N70 5228770.
hello friend how can i write to you?
You sure can, emails emerald310@gmail.com. Thanks for watching.:)
Ever watch Bus Grease Monkey? I think he's freed up a bunch in his videos.
Yes, but don’t remember seeing any where he freed them up. Thanks for watching.
Buen trabajo ,te sigo desde tijuana México saludos ,y bendiciones ...
Just a suggestion, put a mike on so that your voice level stays consistent and clear. Your voice is really low.
Thanks, that was the old go pro I had with a bad mic. The new mic fixed this issue.:) Thanks for watching.:)
@DetroitGarage already subbed. Question, what brand of motor oil do you like to use? I know that it must be straight.weight, low ash content.
@@hoost3056 I run Shell Rotella T1 40W year round. In winter I use both an oil pan and block heater.:)
