I have a 4-71 that runs our sawmill. My great grandfather bought it back in the 50s. It's been sitting for close to 10 years and it had 2 stuck injectors I did what you showed in your video and it worked perfect! Runs great again like it used to. Now time to put it back to work sawing lumber! Thanks for showing everyone your trick!
Thank you so much!! My brother and I have been working on getting our dad's 59 John Deere 440ICD bulldozer running this year. After getting it moved into the barn, changing the oil and a getting new battery and cables, we were able to get it to crank but it never would run. After finding that the injector control tube seemed to be frozen, we found your video. Neither one of is much of a mechanic but we were able to follow your procedure and after purchasing a brass punch and a can of FREE-ALL - BOOM! She started right up!
I have a bus with an 8V92 that has been sitting for 17 years. I watched your video and took off the valve covers to find 7 of the 8 were stuck! I did what you show here and got all 8 free, put the valve covers back on and it fired right up. Amazing!! You rock dude - thanks for doing this video!
Awesome video.i was having a hard time prying off of anything. I ended up welding a nut on the handle of my vicegrips. Then I clamped on like you did and was able to hit the nut with a hammer worked lie a slide hammer. Worked awesome. Appreciate your time
Thanks so much for taking the time to get video of this and explain it. There are still so many of these engines out there, but so few work on them (yours is one of the only videos on RUclips about the two stroke injectors.) This is such a common issue, especially for trucks and buses that sit. And a dangerous issue for the older style fuel rods (one injector sticks, and the engine can run away!)
Thank you for your tip. I actually used an eletric oven since the injectors were of engine. I didn't like the idea of using a hammer or any kind of vilence with such precision engine part. After 15 minutes, injectors start to work perfectly without any punch.
Well that's' going to come in handy. I've got a 653 in my fishboat that gets clean fuel, regular oil changes and run all the time, hope I never have that problem but then there's my landlord's buses, both 871's that have been neglected and sitting. He can take it out of my rent. Got to get a brass chisel. Thanks Bro awesome vid.
Thanks for the info especially the Free All spray lubricant. I'm going to go get some tomorrow. I have 5 - 9290 Detroit injectors that are stuck. I'm going to utilize your method.
I got 1 of the 5 injectors to free up so the rack moves freely, 4 more to go! I made up a jig out of wood to hold each of the injectors in place and I work on them one at a time. I got some Free All, the smell of it reminds me of aero gloss model airplane paint. It’s working thanks to you my friend!!
Thank you for your tip. I actually used an eletric oven since the stick injectors were off the engine. I didn't like the idea of using a hammer or any kind of violence with a such precision engine part. After 15 minutes at 190 degrees F. injectors start to work perfectly without any punch.
Just so you feel better, "you maniac" you butcher"! Lmao now that's out of the way THANK YOU SIR SO MUCH FOR THIS VIDEO!!!! You truly saved my a**!! 1951 6-71 inline reverse rotation bus. Sat 10 plus years. Wouldn't run. This is EXACTLY what was wrong. You method is proven! Thanks again!!!!
Thanks for the information will be getting a 4-53t out of a 1980 gmc grain truck that the valve cover is rotted and will need a rebuild and plan on pitting it in a 1985 chevy military k30. Will be my first detroit 2 stroke
@@Ol2Stroker I don’t know what the definition of runaway is however I exited my gate with a left turn at full speed with no throttle control other than max revs so I’m calling it a runaway… I hope I never experience that again…. If I narrow it down I’ll be sure to let you know
@@Ol2Stroker So you don't suggest priming the engine oil system with an OTC 6492 oil primer? The engine I have is a GOV rebuilt 4-53. I have no idea how long ago this engine was rebuilt, or how long it sat in the warehouse it was found in. It's a General Motors 53, 1957 to 1965. It's a unicorn. Lol
Well it definitely wouldn't hurt bud especially on something in the crate like that. Typically these trucks we mess with have a good coating of oil on everything still even though they've been sitting. You're probably not going to hurt anything cranking it through the starter but make sure the fuels shut off and dont start it till you see oil up top.
question,my 692,its heating up a little,the mechanic opened the blower and the turbines had oil and they moved like quarter inch back and forth,is that my heating problem?and should i run the engine with turbines moving like that
I have a can of Free-All, as I have been testing several different new-to-me penetrating lubes. I got a lungful of the vapor and I wanted to die. It hands down has the worst smell and harshest vapors of any I've ever used. The Starrett M-1, Deep Creep, and Zep 45 cans I've been using at the same time get used way more often, and I can't tell that the Free All is working better than the Deep Creep. The Zep and Deep Creep smell pretty nice actually. (To a guy who likes the smell of diesel and leaded race fuel burning, anyway)
Ahhh your a butcher, just kidding, that's a really fast great fix, like at a mine sights were the boss is like dam your badass and saved hella time🏁🙌🔧🏆🏆🏆
Rare to see a one man person unsticking and starting a runaway engine. Not everyone will run when it runs away on you while hot. You have it under control
My club just purchased a 1992 Prevost RV it has an 8v92, it will start and run but builds no power. Flat ground it'll hit 35-40 WOT, any grade and it slows down to 20 or so. Had it towed to a shop that worked on it for a week. They thought they found the issue, said it had mold in the gas, o e filter was completely black. They cleaned everything and still no power. They gave up, I am now having it shipped here to Ohio. Do you think it could be sticking injectors?
Whoever criticizes this has never worked on a 8 V 71 Detroit you couldn't hurt that truck if you tried built like nails they always told me how you drive a truck with a Detroit in it is both feet flat on the floor enjoyed your video
Michael McGrew It was explained to me when I started as a wash ,tire, brake , and thermoking mech in the early 80s , that your whole hand was to be slammed in the door .
Have 8v92 in a blue bird been sitting couple years but run it every 3 months but I did not crank it for 6 months still starts right up but it runs very rich and smokes now any help would be appreciated
This is for engines that have been sitting a year or more and if thats the case u need to pop the covers off and have a look or u risk a runaway and or pushrod damage. If ur engine is running and sticks one you'll definitely know it. If an injector sticks for any reason other than sitting a long time it needs to be replaced.
Hey , do you answer questions? I'm screwed, 8v71 in 46 ft shrimp trawler went swimming, water over the intake. Got it up and immediately pickled it with diesel till it ran out the dipstick, after draining the brackish water, turned it by hand a few rotations, I have two hot batteries in a checked out starter and it won't quite turn over, even though I can turn it over by hand although tight I know nothing about diesels or shrimping, I'm getting an education on the fly, I thought I would try pulling injectors and see if I can get it to turn over by the starter I don't mind yanking out all 8, matter of fact I want it tight cuz they don't have tow trucks up in the gulf, but I don't want to screw anything up I thought about going ahead and yanking the injectors and taking them and have them rebuilt, can you tell me the process so I don't screw up my whole life here worse than my boat sinking?
you need to remove the injectors and get the water out of the cylinders. pivot the rockers up out of the way by removing the fuel injector lines and the 3/4 bolts holding the rockers. Then there is a 9/16 bolt that holds the injector down. remove that and pry injector out. you should be able to remove them all without removing the rack or bending anything just rotate injector counter clockwise as you pull up and hold rack to no fuel. turn over by hand and get all the water out of the cylinders. i wouldn't be surprised if you bent a rod already it doesn't sound like you're too familiar with engines.
@@Ol2Stroker a rod? I'm not real familiar but I'm pretty sure that's bad I drained the water/ oil out and turned by hand maybe 8-10 rotations assuming I got the salt water out, then pickled with diesel to the brim, drained and put fresh out and filter. I can turn it by hand however it's a little tight. Had the starter checked by rebuilder and they said it should have no issue turning it over, batteries 12.64 volts a piece, yet something seems to be hanging up, binding like Could I still have water in the cylinders, or rust tightening , or you think I already bit the bullet on a rod or something?
You know I don't know but I think the brake free or that brake cleaner is what you need till it is free. The oil don't do nothing till the brake free has worked. Sure after free squirt any kind of oil you want
That was some nasty looking fuel coming out of them. I have a 3-71 to put in a 66 Dodge one ton. I would love to find an RTO 6610 to put behind it... They seem to be hard to find around here.
We had a leaking injector on a brand new 4-53T one time. Supervisor borrowed a hand pump from a Diesel shop (we were in the field)---blocked off the return line on the head, found it that way. Not sure if fuel was coming out from the plunger or it was cracked but fuel was seeping all around the injector on to the head. Basically do what "super pickle" says. Not sure why management didn't have the manufacturers of the machine fix it because machine was brand new and engine should of been under warranty.
I just bought a dump truck with a 6V motor and there’s oil lines coming out of each side of the engine block and they don’t go to anything. They just run oil out. Can you help me figure out what they’re for?
@@Ol2Stroker Thank you Sir ! You have just solved a mystery for me. I am busy fitting a starter to an 8V 71 in anold TEREX 82-40 DA via the inspection hole in the 1 inch belly plate and hit a dead stop when I found that 3;8" pipe. Thought the pipe came from the oil gallery and previous mechanic had dameged/broken an oil line. Shew! Thank You. Now I can go ahead.
I was thinking of getting of getting a truck it’s been sitting and he said the rack is stuck I’m assuming it’s this he wants 1500 do you think it’s worth it
I would like to add that after a procedure like this, make certain that your emergency shutdown is functioning correctly. You never know why an injector hangs up, whether from gum or a drop of water. If it's gummed up that's all well and good, but if it is a speck of rust, it will scratch the bushing or the plunger and the injector's days are numbered, even though it appears to function. Additionally, the whole idea of the spring-loaded levers was to negate the need for a shutdown flap, so your engine may not have one. Just for my own piece of mind, I would always prepare an easy place to put a board over the intake for that initial start, if what I was working on had spring loaded levers.
The emergency shut down is a last resort kind of thing. like trip and run. When you trip it on a runaway engine some times it will blow the seals and then suck the oil from the crankcase and keep running on that oil.. Only sure way is to have a shut off valve on fuel supply at the pump to cut fuel off from injectors. When a fuel injector is stuck fix it right. every see one of these engines coming apart from a run away will make make you learn to do things the correct way. Ever see a truck cab after a fly wheel has tore it up. Or the holes in the shop walls after a Detroit has slung metal through them . general rule balance on front of crank goes first. And depending on year model and type the old ones will come apart at less than 3000 rpm. i have un stuck injectors this way but i had installed fuel cut off before starting engine. After seeing a couple Detroit's come apart days latter. I now remove injector and repair proper way.A new rebuilt injector is only about 80 bucks.Or you can rebuild your own one. ..@@ASPCOT
always before starting up a detroit that has been sitting a long time. check the rack for ease of movement. turn the engine over slowly if possible. stuck injectors will stay compressed. the rack won't move either. i learned the hard way, an old engine started up wide open for a few moments until i hit the flapper. make sure the flapper is open and set on the trip
I have a opportunity to buy one of these for cheeeaaapp , 8v71 for like 350 been sitting in a barn for years waiting on a engine swap . How can you tell what these engines came out of? Easy giveaways ?
Lol ... ever loose one of the spring keepers like that ? Takes a bit of finesse, could drop a valve like that ... Someone's gonna hit the wrong spring & they'll blame it on your video .🤣
+jr cheat Hey man its visible to the rest of youtube may wanna edit your reply if yall got in touch. RUclips messenger is always messed up. Thank you for the video +Ol2stroker working on a 453T swap and 4 is stuck. Its going in a 51 chevy cab over hopefully everything lasts long enough to work out any bugs and justify removing the cab and rebuilding. It's a detroit it will keep on goin
If y'all want this to stop happening, use some 2 stroke fuel additive. Just google whats out there... just make sure it's not red in color (farm fuel is red, and you'll get a major ticket if they find it in a road truck).
Or filter and use a gallon black motor oil. Turns whole tank of fuel black and is legal.[ up to 10 per cent ] It would really take a lot of 2 stroke oil to make any difference in a tank of fuel. Yes farm fuel is red and easy to spot, But when they are checking your fuel they do not only go by color. Lots of dump truck owners buy and use old transformer oil [ from the transformer oil changes ] in there trucks. It looks like diesel. And is cheap. But if you get caught the fine is pretty high. But thousands of gallons are bought and used every year from electric service companies.
I use 2 stroke oil in the fuel in my normal old diesels. Usually it is 1/2 oz per gallon of fuel..... but have used a 1 to 1 ratio.. I am planning to get an old Detroit so I will have to check the injectors
"Ah F#ck it's getting on my phone!" lmao You drop the F-bombs like a champion... cussing in general is a fine art in your hands. lol Nice!

Thank you for your kindness in showing us this technique.
I used my heat shrink wrap electric gun to heat the injector, then sprayed Kroil oil in the injectors, worked fantasticly

sometimes you have to remove the entire control arm assembly and work each separately. not a tough job. heat, spray and tap back and forth

This is for engines that have been sitting a year or more and if thats the case u need to pop the covers off and have a look or u risk a runaway and or pushrod damage.

How do you short the injectors to see which one is bad?
Blue10AEMia on my powerstroke i unplugged each one while it was running id imagine it could be different with mechanical injection
Blue10AEMia - you push down on the plunger holding it in the down position.
12v71 diesel in oil can stuck injectors cause this or do i need to do something else?

yes and yes.
@@Ol2Stroker thank you, I plan on a 4-53T swap in my 84 M1008/K30. Crazy right? LOL
I would like to add that after a procedure like this, make certain that your emergency shutdown is functioning correctly. You never know why an injector hangs up, whether from gum or a drop of water. If it's gummed up that's all well and good, but if it is a speck of rust, it will scratch the bushing or the plunger and the injector's days are numbered, even though it appears to function. Additionally, the whole idea of the spring-loaded levers was to negate the need for a shutdown flap, so your engine may not have one. Just for my own piece of mind, I would always prepare an easy place to put a board over the intake for that initial start, if what I was working on had spring loaded levers.
The emergency shut down is a last resort kind of thing. like trip and run. When you trip it on a runaway engine some times it will blow the seals and then suck the oil from the crankcase and keep running on that oil.. Only sure way is to have a shut off valve on fuel supply at the pump to cut fuel off from injectors. When a fuel injector is stuck fix it right. every see one of these engines coming apart from a run away will make make you learn to do things the correct way. Ever see a truck cab after a fly wheel has tore it up. Or the holes in the shop walls after a Detroit has slung metal through them . general rule balance on front of crank goes first. And depending on year model and type the old ones will come apart at less than 3000 rpm. i have un stuck injectors this way but i had installed fuel cut off before starting engine. After seeing a couple Detroit's come apart days latter. I now remove injector and repair proper way.A new rebuilt injector is only about 80 bucks.Or you can rebuild your own one. ..@@ASPCOT
always before starting up a detroit that has been sitting a long time. check the rack for ease of movement. turn the engine over slowly if possible. stuck injectors will stay compressed. the rack won't move either. i learned the hard way, an old engine started up wide open for a few moments until i hit the flapper. make sure the flapper is open and set on the trip
I have a opportunity to buy one of these for cheeeaaapp , 8v71 for like 350 been sitting in a barn for years waiting on a engine swap . How can you tell what these engines came out of? Easy giveaways ?
Cuántos litros de aceite lleva el motor 2-71?
Im not sure what you said... but if you're asking if this procedure works on a 2-71... it should!
Lol ... ever loose one of the spring keepers like that ? Takes a bit of finesse, could drop a valve like that ... Someone's gonna hit the wrong spring & they'll blame it on your video .🤣
....and it starts up and runs away.
Shit I go to the butcher when I want the best cuts
I've found the video

+jr cheat Hey man its visible to the rest of youtube may wanna edit your reply if yall got in touch. RUclips messenger is always messed up. Thank you for the video +Ol2stroker working on a 453T swap and 4 is stuck. Its going in a 51 chevy cab over hopefully everything lasts long enough to work out any bugs and justify removing the cab and rebuilding. It's a detroit it will keep on goin
That is a Detroit, if force doesn't work apply more force
Nice job
Get a cameraman next time.
Post more then.
lol
LOL
If y'all want this to stop happening, use some 2 stroke fuel additive. Just google whats out there... just make sure it's not red in color (farm fuel is red, and you'll get a major ticket if they find it in a road truck).
Or filter and use a gallon black motor oil. Turns whole tank of fuel black and is legal.[ up to 10 per cent ] It would really take a lot of 2 stroke oil to make any difference in a tank of fuel. Yes farm fuel is red and easy to spot, But when they are checking your fuel they do not only go by color. Lots of dump truck owners buy and use old transformer oil [ from the transformer oil changes ] in there trucks. It looks like diesel. And is cheap. But if you get caught the fine is pretty high. But thousands of gallons are bought and used every year from electric service companies.
I use 2 stroke oil in the fuel in my normal old diesels. Usually it is 1/2 oz per gallon of fuel..... but have used a 1 to 1 ratio.. I am planning to get an old Detroit so I will have to check the injectors
Such a filthy mouth, every other word. But....
Thanks for the information.
Oooooooo your a butcher lmao
Foul language in the first 30 seconds? You're not ready for prime time.
