As one of the backyard mechanics you mentioned, your content is highly valuable. Please keep up the good work.
This guy has been a bible for me, I recently started my own business and somehow, I started getting a ton of Bobcat coming in the door. With little experience on Bobcat, this guys videos have saved me, I look forward to many more. !!
Thank you so much
You are God Sent

There is no one that educates us better. Many many thanks I’m hoping you end up with a TV show doing this stuff one day!
That’s probably the best repair video I’ve ever seen! You are truly the bobcat Jesus!!
This video helped me immensely with repairing my t450 that I rely so heavily on. Thanks a ton!!
I am currently watching all of your videos. No one has ever explained the function and repair so well. Greetings from Germany and many thanks.
always enjoy to see professional people do their job. I like your simple injector test tool .well done mate.
My guy! Man I cannot thank you enough. Definitely helped with my T550. You are a GODsend. Keep up the phenomenal videos.
I appreciate all of your videos! Thank you for taking the time to help the backyard guys.
You bet!
Thank you so much for your videos. I bought a old bobcat to help me manage my large property- your videos have saved me in time and money
Wonderful statement at the end ! If everyone thought the same it would make the future so much easier for us all
This guy is thorough, excellent instructor
Thank you very much
Great video!
Appreciate your efforts in posting these.
I've never worked on or even needed to repair a Bobcat. I just watched this with your brother for entertainment purposes only. And holy smokes! I am pretty much an expert now. Start working in the field tomorrow. You the best!
Please add more video like this, I learnt a lot from your channel.
Big thanks.
Thanks for your videos. I have learned a lot from you . I’m an automotive mechanic and this year I started working on construction equipment and is another kind of bull , I like it’s good $ to be made . Thank you again .
You will like it much more than automotive.
Love seeing what you're doing man. Love the videos, I work at a Doosan dealer and have a whole lot of bobcats rolling through. Great info Keep it up!!
Glad you enjoy the videos!
That service van is the best I have seen
Impressive video, very useful hints. I get so bored with most repair videos, I watched yours all the way through.
Thanks for watching!
Great video. I feel you treat customers machine like you would your own. Thanks for the lesson. John
Thanks for watching!
awesome Videos! working on my 2016 T550 fuel problems and fixed u r a good man! thank a lot!!
Very nice work and really enjoyed the video!
Another great video cannot believe I waited this long to check this one out
Like always pretty professional thanks for your time and your knowledge
I appreciate that!

Thank you, and let me know if there's anything specific you would like to see.
Great video. Thank you for sharing
this is another great video. this kind information really help me in order to repair my s550. thanks a lot. congratulations sincerly.
Glad it helped
Dude you’re the best!!!
I have a T650 that has that code, I’m definitely getting the tool made and check my skid steer out.
I’ll let you know what happens.
Thanks from Texas.
Heck of a mechanic you sir are awesome
Awesome vid with clear explanations as you work thru. : Tom
Man these video's are awesome! This is another great video! Really like that you get right to it and don't waste a bunch of time. Can you recommend some quality hex wrenches?
Thank you for making this video. Great informations
Thanks again for another great video. I have a new e42r2 so Im not sure if it’s a lot alike but this seemed like good info for when mine gets to be aged. Thanks again.
Thanks for sharing your knowledge 👍🏼👍🏼👌
Vey good information thank u lot for what u do Keep up the good work
Good Job. Thank You for the info.
Great work. Very informative. Keep it up.
Great video !! Do new injectors need “coding” with bobcat software ? Thanks
This vídeo rely help me to try to find this kind of failure in a s550, and solve it, thanks a lot
Greatly appreciated for your time.
My pleasure
Good job I have the same problem with my skid steer
Lovin these videos…I’m having a fuel issue with my S770…93 horse kabota
Collapsed primer bulb…won’t even draw out of a remote can
I don’t even own a bobcat new enough to have these problems but love watching how to diagnose and repair I really appreciate these videos and strongly hope you keep them coming
Thank you for your information
This guy is awesome thank you foe taking me back to school
"Hopefully that helped"...you are so humble man. the info you share with us is priceless. For those of us with Bobcats, alot of times we feel very alone with no support. Your videos are immensely helpful to put it mildly. My T300 loses power on very cold days in northern Canada if I leave it out overnight, even if it's plugged in overnight. I squeeze the primer bulb and it doesn't readily fill up until I start the machine then it seems to. Also, it takes a few squeezes to get fuel to come out the vent above the fuel filter. I've even opened the purge nut and I have to squeeze the bulb several times until fuel comes out. You think it's water/ice in the tank?
Thank you for the kind comments. Depending on which fuel pickup tube you have in the tank it is possible for ice or gelled fuel to build up around the pickup screen. Have you noticed the primer sucking flat when you start to lose power? That would be an indication of a restriction in the tank. Also check the condition of the lift pump by opening bleed screw on filter housing and turn the engine over with starter and you should get a good strong stream of fuel from the bleeder while the engine is turning over. Sometimes a weak lift pump can case similar issues.
@@tetradgroup Thank you so much. Warming up to -8 tomorrow so I'll try the lift pump check. Was -40C today with windchill. When the unit dies, the primer is empty but not collapsed because of the cold I suspect. I've watched so many of your videos, I'm going to open the cab up tomorrow and see if I can get the pick up line out and replace. Watching your videos has given me a real sense of confidence that I can at least begin to troubleshoot issues.
Mine was doing this in Saskatchewan, had to put a new pickup in
Your info is very,very helpfull. Thank you a lot
Awesomeness video well done
You are a legend, thank you so much!
Well, thanks!!
Great job
I work at a bobcat dealer and one of my favorite jobs is doing injectors, dont know why but I love doing them. I can't tell you how many machines ive done where the customer will put injectors in and then bring the machine in because it runs rough or whatever. Quick bit of coding, mdp learning and send them back out. I dont know if this is the proper way but its how ive always done it, i put a little bit of grease on that fire ring to hold it on the tip of the injector and then slide it in
Very good information and good to know
Glad it was helpful!
many thanks for the infromation
Thank you God bless you...
Thanks so much
Absolutely killer video!!! Touched on a lot of very important points!!
wanna thank you so much was very helpful
nice to meet you
Just have a word for you, thank you.
Thanks!
Bro your the best 💯
Great information ,
I had one injector leaking the same way. Changed all 4 and now it still won’t start but my low pressure code went away . I pulled sensor and it cranked normal then it actually sped up instead of slowing down.. the metering valve is working and I did not find any noticeable material
Thanks it help me lot.
Glad to hear that
Thank you please any help will Appreciate...
Thanks again
Amazing
Very nice video. Thank you!
One Newby? : why is there a fuel hose going to the injectors and a return hose? Why return? Is the how a car works?
Excellent question. The injectors work very hard under extreme pressure and it is necessary for the injectors to have some fuel leakage to help actuate, lubricate, and cool the injector.
dude u rock
Just wanted to reach out and say thank you for taking the time to post this very detailed video. Found the cause of my no start it was a stuck open injector clear hose test worked great! I'm now chasing another issue where I need to bleed the fuel filter in order to get it to start. Almost everytime.... After bleeding the top screw on the filter cartridge it fires up and runs great, Is there an inline check valve or something that has failed on my machine? not sure where this air/ loss of prime is originating. Even ran the filter inlet to different fuel tank to isolate it being a cracked line further up stream. Any ideas??? Thanks again!!!
Vince
Thanks
Great Video and easily understood! I apologize, for being off topic, but I don't know how else to contact you. I have a 2017 T-770 with an L 7404 error code coming on - It runs (at idle only, won't rev up) for 30 seconds or so, and then the headlights come on as the unit shuts down. I sure would appreciate any clues you have, or advice. Thanks so much, Bob
You are the best
Nice videos.👌 Do you recommend buying Diesel Laptop or Jaltest?
Man you do a great job explaining what you’re doing!!! We have a T590 with the same engine. The water wasn’t drained out of the fuel filter and the machine stopped running. I replaced the filter and went through the sequence of bleeding the air out. Still no start. Do you think I would have a contaminated pump or rail? What’s my next step the clear hose on the return lines to see how the injectors are performing?? Any help is appreciated!! Definitely followed and liked!! Thanks
Start with removing the drive belt. If it still will not start, then the the leak test. Do you have any active codes?
Love your videos , I am a dairy farmer and own 7 bobcats . I put 500 hrs per month on some of them . Just wondering if you have ever had trouble with drive Moter carrier bearings going out which then the seal goes out and fills the gear case with hyd oil .
Yes, not uncommon failure. There was a design chang on many of the M series skids due to seal failures in the carrier and not necessarily bearing failures.
What is the torque specs for the hold down bolts?
great video Have a t450 no start fuel flows out all 4 return lines right away 3 seconds new injectors and fuel rail installed fuel also coming out return lines pulled off any thoughts
Fuel should not back flow thru return lines unless there is a problem with the pump or a restriction on return line going back to tank.
Is it possible for the fuel rail sensor to go bad and trigger full pressure? Working on a s590, hard start. Replaced fuel filter, upgraded style. Doing a 1000hr service.
It has problems starting especially when it's cold. It smokes when cranking so I know its getting fuel. Seems like bat is bad, tested 2x. Good bat. Really really hard cranking. Will test starter also.
Great vids. Bet bobcat loves you!
Thanks for the comment. With out software to test the injectors I would start with a compression test on the cylinders. I don't think the rail sensor is bad because it would code out and not fire the injectors and since you have smoke then it sounds like rail pressure is satisfied and injectors are firing.
I just got a 2017 T595 that doesn't start and has no code popping up. What valve is the most common to create the trouble where the machine won't start
I have a 2017 t550 I replaced injector. And it ran fine then died could a clogged pickup tube cause it not to start
do i need to plug off the injector return lines? i start to get a lot of air in the output of the injectors with the return lines unplugged. 2018 T770 d34P
hey question I have 2016 bobcat t650 with D24 engine my machine turn on im getting E0000157--22 code and E000094-11 I did replace fuel filter and put new fuel. where should I start do leak test ?
What computer scanner are you using to program them? Link please to purchase
Hello sir, where are these engines made. They seem to be very close to the Daedong engine that is used in Kioti tractors.
Great video man.
I got a bobcat dead in the middle of no where. It doesn’t start I did that injector test and I got diesel coming out of all injectors but a lot more for injector 1 and 2. Is it safe to say they’re all leaking?
They are supposed to leak a little, to much and it won't start. You could try replacing 1 and 2 and test again
I have just tested mine it only starts with starting fluid, anyhow three of them fill up that fast. Do you think it is 3 bad injectors? And should I replace the whole fuel system? Bobcat wants 7500 for a fuel system kit including the pump. I found one on expert diesel online for around 3200. What are your thoughts on the two.
thats a brand new machine
What is the wire that goes to the top of the injector? What does it do?
Hi there! I have been sharing these videos with my husband he has a T590 skid steer. Your videos are extreme helpful especially when talking about the injectors! I'd like to ask you about the fuel tanks and cleaning those is there a cleaner Bobcat sells that you can put in them and cleans or whats the best way of doing that?
Great question, I'm actually working on a video talking about fuel and fuel treatment. Bobcat sales their own fuel treatment which is a proprietary blend and and highly recommend using to protect your fuel system. Best place to purchase is a bobcat dealer but it is available online thru Bobcat parts but they require a case purchase.
@@tetradgroup okay thank you so much for the info! I just have one more question does the pistons gotta be top dead center to time it? He has timed it twice and have had limited time working on it and have some free time. This machine only has 300hrs on it so you can understand the eagerness of wanting it running!
@@nikkithornton1002 # 1 has to be TDC but does not matter if it's on compression or exhaust stroke
@@tetradgroup okay thank you for the info. Man if that's all it is keeping it from running right he will be so thrilled lol
What if the moter does slow down when you have fuel rail sensor unpluded
Hello, had a low rail pressure code. S570. Replaced injectors, it started once for about 10-15 sec. Made a slightly funny noise and shut off, now it is a crank no start with no codes. Pickup and all lines where replaced as well. This will likely end up at bobcat as I don’t want to throw more parts at it but definitely had at least one bad injector. Any suggestions or insights? Thanks
Probably a contaminated pump
Need help with my Mt85 that won’t shut off.
Thank you for the great vid, very informative. Have a similar issue with a track loader(same d24 system). We tested the pressure sensor by un-plugging it and cranking it over with no audible difference in resistance from fuel pressure being “wide open”. Also static(leak) tested the injectors from the fuel return as you did. Had #4/3put out appx 4” of fuel to 1/8” tube, and injectors #2/1put out appx 3” of fuel to 1/8” tubing(same setup you used). This happened in appx 5 seconds, which seemed to be quick) . Wondering what to test next. Seems as though not getting enough pressure as there was no “resistance” upon cranking with pressure sensor unplugged(sending unit/pump?) or could all injectors be bad(highly unlikely but they all put out similar amount of fuel fairly quickly? but completely possible in my world 🤦🏼♂️) The fuel system has been completely purged and cleared. It did have water issue that came from a faulty fuel cap(😫😫😫), and that problem has been diagnosed and corrected. New clean fuel/filter/all things good now. Just not sure where to go from here. Any help/advice would be greatly appreciated!! Happy New Years!!
It’s a 2017 t595 w low hours and never had any issues with it whatsoever until now(obviously the water in the fuel) thanks in advance
How long did you crank to get the 4" of fuel? Can you send me a picture of the tubes after 5 seconds of cranking? bobcatissues@gmail.com
It was appx 5/7 seconds- seems like way too much fuel for such a short time- that would mean all the injectors are bad, yes? I understand the water could have damaged them, but all of them seems kind of crazy…. But would just be my luck as of late😆😫
And this is the only vid that simply explains how to test w/o software…. You’ve probably helped thousands of severely frustrated Bobcat owners who aren’t driving around with the kind of money it would cost just to get a diagnosis, let alone fixed… again, thank you!!
And just kind of wanting to know what else I can test myself before I go buying 4 injectors and then it still won’t work..👍🏻
Also, to test each injector individually, can you “cap”(1/8” tube w plug) to test each one? Will that cause any unwanted damage to any of the injectors?
Hi I did the test with the clear hose and my injector number 4 had zero fuel come through inject 2 and 3 2 worse than 3 dumped a ton of fuel out of the return
Here in Europe we have much more experience with Diesel engines ,,Most of our cars have diesel than petrol engines,,And it's been like that from the mid 1990s,,,And I can tell you now that you don't have to replace the high pressure lines going to the injectors once there is no damage to them,,,They can be used over and over ,,,
got a bobcat 322 excavator , it has a fuel starvation problem,,, runs for about 5 minutes then starts to dog out... go to the squeeze ball and pump it up and it runs like a champ again, but only for a few minutes.... i have changed out all the fuel lines, cleaned the fuel tank , new filter, new pump, even put a sediment bowl in the line before the fuel filter... stlll looses prime and dogs out. it is acting like old style vapor lock, cant find any leaks anywhere.. it does run longer with the rear door off but that only extends the time before it looses power... check the sediment bowl, it is low on fuel, squeeze the primer bulb and it picks up again but only for a few minutes.... any suggestions ? it is sucking in air somewhere but i cant find it
Pre fill your fuel filter? If the injector can plug with something so small should you not pre fill the filter out of your Jerry can?
It is not recommended to pre fill the filter from a can. Install filter and use primer bulb to fill filter.
would that cause the fuel to flow out of all injectors like your video
No, how many inches after 6 inches?
S590 bs4 mc have problem water in fuel we got water in coman Rai ..all water clear start the mc engine have abnormal sound and and 1500rpm only no more incrise rmp .. have erore coad also fuel pressure low .. what is the issu may fuel pump fail or injector fail ..can u help me
Appointments for consultation can be made at www.4tetradgroup.com
So you say you don’t need to program the injectors immediately but it won’t work at peak performance. So once the problem is solved with new injectors is the next step to get them programmed by someone with the software?
That's correct, the sooner the better.
I got a dead 2015 s590 w/Doosan. Died while operating. Cranks, no start. Replaced fuel filter. I cracked the line from the pump to the fuel rail and cranked... no pressure from the pump. Took the fuel meter valve out.. cranked. And fuel shot out of the opening... do I got a dead fuel valve?? Can it be tested?
That's a tough one, it can only be tested with software and it's almost $1000 to replace valve. Do you have any codes? What exactly were you doing when it died? Try not to crack any lines on fuel system. Try to remove drive belt to eliminate any possibility of hydraulic load on engine.
@@tetradgroup was just pushing dirt around working on getting a pad ready for concrete. Noting really tough. Never had a problem with this machine usually runs like a top. Only code I'm getting is a low battery from cranking it. I put a charger on it. I saw that price ugh..lol. desiel pro has then for $200. Weird it's not throwing a code though.
I just ran your test and found the return side is producing fuel causing a disconnect from whichever injector has the weakest clamp
