What a great video! Very helpful and also hilarious...at the 6:56 mark. I would assume your son walks in the background and samples your diesel fuel. Im sure he replaced your jar of diesel used earlier in the video with pickle juice. I was laughing so hard! Hilarious 🤣🤣🤣🤣🤣🤣 I love humor.. what bright young man.
Awesome video, immensely helpful. Thank you!
If the primer bulb won't prime odds are that the flapper valves inside the bulb are worn out or stiffened up with age and they need to be replaced or the bulb can be replaced entirely. You should not need to finger block the hose to get it to work.
You made it so easy before it was terrifying.
On an 863, do we have to pull the tank out or no?
No but it sucks, you will have to remove motor mounts under cab and use a long pry bar to lift pump side of engine to access to pick up tube. Use a helper to work pry bar while you wedge the engine up. My first one took a couple hours but much easier now that I know exactly what to do. I really sucks but definitely doable.
Great video. Very detailed. Hope your helper doesn't go peeing on a fire anytime soon ☺️
Lol, I saw that! Diesel fuel?!?
That's fake. Nobody is that stupid...
@@MFallon303 of course it's fake. It's just humor
@MFallon303 not a chance, that's raw number 2 diesel fuel, definitely not lemon lime Gatorade, surely no mechanic, or his kid, has enough of a sense of humor to make misleading side shows, get real, it's on the internet it HAS to be face value and true!
Ha ha I just saw what you were talking about
Your son is running on diesel.
If you ever get the chance, I would like to watch a quick video of an engine bay clean out. It would be nice to see how someone who does it often gets it clean.
I was just thinking that same thing
OMFG!!! I laughed SO HARD when the kid drinks the diesel fuel!!!! Great humor!
Finally a video with step by step audio and video. I learned a lot from this video....I wish everyone on TH-cam would do video's this well
Lol... first day with a bobcat and here I am wanting to drink some diesel. Excellent vid :)
Huge, huge help. Thank you for taking the time to do this. I appreciate it a lot!
Nice funny son😂😂😂
Mmmm, biodiesel is good stuff. 😉
Great video, kids hilarious 😂.
Thank you, your explanation is excellent
I really enjoy watching your videos. You learn a lot and they are very well done. But this video is a highlight when the young man comes in the background and drinks from the glass with diesel..... Something like that should be included in a video more often. Thank you for this great fun.🤣😂🤣
Thanks for watching!
Awesome Video...Your helper was hilarious too! Thanks
I appreciate your well informed in detail video plus the fun entertainment on the back thanks to your helper buddy. I hope he uses regular diesel Flex fuel diesel I don't know if you going to blow up a gasket or something's going to go wrong with his exhaust pipe😅jk thank you very much once again and you guys have a great day
Thank you for this video. I had a no start on my 763 and after watching this I realized I wasn't getting that "click" when I turned the key. Bad fuel solenoid which I'll be replacing. Thanks again for the informative and well made video.
Check your Fuses first 😮....
Love the video it was very well detailed and in-depth on a no start
Duuuuuude!!! I’m about dead watching that kid drink diesel 😂
Just love all your videos, your bobcat knowledge is unsurpassed, your experience shows up in the videos when you demonstrate HOW YOU DO IT and make it look so so simple. I do have a question for you, in an 863 the fuel pickup is located further forward, in what seems an almost impossible place compared to the 763. Is it possible to replace the tank pickup tube without removing the engine?
I remove the engine mounts on the 863 and have a helper use a prybar to lift the pump side to gain access to pickup tube.
This video brought me directly to my problem and got me up and running. Great information 👍
Perfect! Glad it helped and I really appreciate the support!
My 863g lost its fuel pickup tube during a snowfall of course. Luckily my bobcat mechanic was out on another machine callnearby. He said he'll be able to move the bobcat by going through the fuel filter and a gallon jug of fuel. He had me out of the way in matter of seconds. Do you know about this? I thought it was the slickest thing I saw. For a couple dollars to replace a fuel pickup hose, I replace my hose every fall so there is no problems. Thanks for your videos and help.
Great video! Occasionally my S185 will die out with the primer bulb sucked flat and not restart into I let it sit for a while. Biggest clue was when I removed the fuel cap and heard a whooshing sound as air rushed in. Apparently my tank is somehow pulling a vacuum and not venting. Is there a breather vent somewhere? I've searched online and cannot find and information on this. Thank you sir.
Great video...easy to watch and understand. Really appreciate the professional advice. Thank you
A tech from Bobcat did return my call. On my T630, they recommend the fuel line itself be cut to 16.49"
My 753 right side drive is just barely moving? No leak. All other hydraulics works fine. Just had a seal kit put in the drive motor but still just barely moving. Any suggestions?
Thank you very much for your video
It’s very helpful I really appreciate it thanks again
Thanks I just fixed 325 excavator that was the problem I just paying almost $600 and the dealer by in the solenoid and all the parts and it was the hose
Thanks for sharing! It helped me get mine back running. Is that your son drinking out of that jar. He looks like my grandson.
I have that problem now , But I got a reconditioned engine put into it 751 Skid steer 2years ago and where the Stop valve and rubber gramet fits down in the tank can’t find it , They must have put the tank in backwards, must check if there is a side plate so I can see in
I ran out of diesel in my 753 and tried starting it after refilling it with no luck. Tried priming by getting air out of the fuel filter but just kept pushing out air. I tried starting it a few times. Is it possible there is too much air in there?
What do you do if you can't get the primer bulb to pump up?I put a new one on and still can't get it to pump up. I put a new check valve in it. The old o e was still on there.
753, replaced pickup tube, replaced lift pump, runs and idles fine, primer never collapsed but under load seems to starve for fuel. Any clues?
kid drinking diesel was really mtn dew? right? lmao. anyways loved the vid. good job bro your helping me alot
Like always great job there, l just wondering how that boy likes that diesel limonade lol 😂😂😂
Remove the fuel cap remove the primer bulb from the line coming from the tank blow into it with your mouth. If you hear gouging from the tank your check ball is not seating if you can easily blow back and hear the air sound coming from the tank then your pick up tube has come apart.
I’ve got a 7775 John Deere not getting fuel from the pickup tube I’m trying to see if it’s okay to unscrew it and take it out or is there something that would break down there with me unscrewing it?
No mention of the length of pick up tube. Bobcat says it needs to be cut to length, but what length?
Great video sir 👍 how can I get in touch with you I have same problem on my bobcat 763 in what state do you are located?
I have a 763 and the push button electronics will not light up do you have any idea what it could be?
That kid is for real, he has diesel running through his veins. I've got a 463 that won't start when it's hot. any suggestions?
your son drinking from jar is funny .I this a few times.watched
Hi, this is a fantastic video! Thank-you for the taking the time to educate your viewers. I have a similar problem with a Bobcat 864 and hoping you might have some suggestions. The machine was running fine and then it just stopped when sitting at idle. I discovered both the pickup line and return line were in fact completely broke off in the tank. I went through the repair as you instructed, but now I am having difficulty getting the engine to run right. I bled the line on the top of fuel filter per your instruction, yet when the engine is started, it blows a lot of black smoke and runs rough. It has the Deutz engine so it doesn't appear to have the jet valve you shared in the this video. Any suggestions on next steps would be greatly appreciated. Thank-you!
Make sure the lift pump is working by opening the bleeder screw on the fuel filter housing with engine running or while trying to start and see if you get a nice steady stream of fuel from bleeder screw. The black smoke is a little concerning, because black smoke is unburnt fuel which is caused from too much fuel and not enough air. Again first check the lift pump if it's working you might need to check the turbocharger.
Thank-you! Lift pump is working great. Loved the tip on black smoke caused by not enough air. I changed out the air filters, which were pretty dirty, and the machine is working great again. A little smoke when starting, but then the exhaust turns clear with a nice idle. That did the trick. Not sure why it wasn't doing that before the fuel line failure but it seems to all be back in harmony now. Thanks again for your time and posts. They are life saver! Now to follow your other video on changing out the timing belt. Again, thank-you so much!
Thanks for these videos, they very educational for a recent bobcat owner like me. I have an 843b. The tilt linkage bar runs under the pump with a pivot right in the center. The bushing is so worn it basically won't work. I have gotten the nut off the bolt but there isn't room for the washer to come off. 1) Where is the head of the bolt? 2) Do I need to loosen the pump to make this repair. Thanks again for the videos.

What type of Oreilly hydraulic fluid are you using in that bucket sitting there?
HOW???? how did you raise the arms of the machine if it won't start?
Great video exactly the problem that we had and this helped with being able to fix this on our own. Thank you!!!
Can you do a video on troubleshooting a controller on a g series 773?
Thank you gracias for the video...
Your son must've found the happy juice 😂
Good video. What if I don’t have a hand pump?
Fantastic information keep them coming
So no one is going to talk about the kid drinking diesel like it's kool-aid??
Can you do this on 863 without pulling the engine?
Great video! Thanks! Question! I believe my fuel shut off selonoid is bad. If it is bad, does it stay stuck in the 'OFF' position? The only way it starts is if I have someone in the cab turn it over and I manually move the shut off valve to the right 'off of the 'OFF' position, but then the key will not shuit off the engine. I can pull the key right out and it keeps running.? Thanks
Yes, if the solenoid was to fail it will fail in the off position. There's actually a stiff spring inside that pushes it to the off position. It sounds like the plunger is probably rusted and not moving freely. If you disconnect it from the shut off lever you should be able to push it in and it should pop right back out under spring pressure. Try that with the key off. With the key on if you push the solenoid in to the right it should hold itself via the electromagnet. The red wire is constant 12 volts with key on. The white wire is only for the pull and is 12 volts momentarily.
Another great video .From beginning to end very informative.
Thanks!
Bulbs hardly work much usually need replace
Is there an easy to get to drain plug on the fuel tank?
Thank you. I was able to fix my Bobcat 873 due to watching this. The fuel pickup tube is nearly impossible to get to in this model so I drilled a new hole in the fuel tank for a new fuel pickup tube, and plugged the old line. She's running like a champ now.
Excellent job
Having a fuel starvation issue on a 2012 t770. Primer is collapsed. Removed fuel line and blew through line. Was clogged. So I know there's debris in tank. Where about is the drain?
No drain on the T770. You can drill a hole in bottom of tank and add a plug however
Haha that cracked me up! Well done!
Hey I am back again...I have this pick up tube issue and am currently repairing with your help. Question I have a 2001 763 G series, I want to change the fuel filter. Do you have a video on this?
Disregard, stupid question. But I am going to change the Hydro Filter if you have any videos for that.
thanks you fixed my 763!! One question, what's the best way to get a bucket off that's never been removed for 10+ years and the bob-tach plate and bucket pins are solid rust?
I use an air hammer from the bottom. In extreme cases I have to cut the bottom off the pins to remove bucket and use lots of heat on the pin boss
Great job Thanks , A job I have to do!!
I really need some help on a no start t250 no start
I really like your video, you explain so well and so detailed. Someone with very little knowledge like me understood perfectly. Keep up with your video.

Very good thank you. Can you do a video on alternator replacement on a 2007 s 130?
I'm actually about to do a video on an alternator install on a 763 which will be very similar to the s130. Thank you for the suggestion
I had a hydraulic leak on my 743. Had to pull the motor, got it fixed, replaced the motor, and now it takes 5 to 10 minutes to get started. Just turns over, until finally it'll hit a little, then more turning over until it eventually catches enough to run. Any ideas? I've replaced my line from the tank to the fuel filter, primed it, bulb got firm. Then was gonna replace the line from the fuel filter to the pump, and it was full, so I left it. Bought a new fuel pump (or lift pump maybe), but haven't put it on yet.

Forget the skit steer how your son doing lol
I have a 2018 T650 after about 30 minutes it shows a code that it's not talking to the computer system how do I fix this
You can contact us @ www.4tetradgroup.com for a consultation. Ill need to know the exact symptoms and code you are getting.
I have a T300 with fuel starvation.. it does start and run but fuel primer ball gets flat.
Whats your suggestion
Start with pickup tube and check the 90⁰ fitting in the top of tank, they like to clogg up at the 90⁰
Hello, bobcat s650 doosan skidsteer, can I access the fuel pickup tube from under the cab?
Should be able to, the difficulty depends on serial number and options the machine is equipped with. All the pickup tubes can be changed from under the cab and some are just more difficult than others.
Lol 😂drinking the Diesel
hey i have been watching your videos and ihave sibsribed to your chanel you don't have any information on a 751-C series
Thank you so much for watching and subscribing! I truly appreciate it! The next one I get, I will try to get that recorded! If you have any additional questions, please contact me at www.4tetradgroup.com
Agree a great video... thanks
Awsome video.. hope it'll help me get my 753 started.. my little brother didn't pay attention to the fuel when he borrowed it and ran it dry..put Fresh fuel in it now itll run and just stall like it ran out again
Great video Thanks.
What about the fuel filter?
Do you have any experience with fault code m9314- it’s on a Nearly new 30hr e48 bobcat mini excavator.
Probably the electric fuel pump is faulty, kinked lines, or fuel delivery issue. sometimes new machines will have some debris in the tank from manufacturing that causes problems. I would make sure the priming pump is working when you turn the key on.
Lift pump was replaced , machine was ran with out issue by bobcat then returned to me - ran for 1hr fault returned - shut off - restarted -after verifying water separator was drained - started back up and has been running without issue for nearly tanks ??? lol I guess it’s good now
great video thanks
Why don't you crack any injector lines 😯...?
It has also 2 other places to get fuel out and get the Air out besides the Cracking the Injector lines, one of them is on the top of the Filter Housing and the other one is a Little Small Wheel 🛞 that you can turn it and then squeezing the bulb will get the Air out of the Line...
I'm a 69 yr old female flower farmer.
I hope I can fix my Bobcat myself
It does start but won't idle properly. Feels like fuel supply. I guess I should check the fuel filter first
Great help
Bless Have you ever a video about a T190 having false overheating problems, when it’s not really overheating. Great videos
I have a 773g. I was able to solve my problems with it because of this video. The biggest thing was reinstalling the grommet. All the other videos made the process so difficult.
What happens when water gets into system via bad fuel? I have a T250 that got some dirty fuel and now the only way to crank is to spray starting fluid to fire off, bad injectors? or injector pump?
I think this is my problem on my 863, although I think pick up tube is intact but there is probably a lot of contamination in tank. Also lift pump is leaking from cap so I think it is either going or apparently I have heard a screen in there needs regular cleaning. I will drain tank and check screen tonight once I get machine thawed out.
I have a 2013 t650 with the kubota that collapses the primer bulb only in the winter. I googled the tube and it looks like it could be metal? I was going to replace the pickup tube and primer bulb to try and solve the problem. Runs fine in the summer.
Depends on winter, When its near 0 or below any moisture in the tank will freeze around the metal pickup and cause the symptoms you are describing.
@@tetradgroup thanks for the reply
That actually really makes sense because when it runs for a while the heat from the engine must melt the water at the bottom. It's always when it sits overnight and you start it that it wants to collapse the primer bulb. Going to drain the tank and see what i get. Thanks again!
EXCELLENT!!!!!!!! EXCELLENT video. Explained very well. Wish I had this video 3 years ago and I would not have to redo it again. Thanks
Thanks for the entertaining video. I'm working on a 743, which is somewhat different. It is close enough to get me thinking about things that helped resolve my problem, which was all the proper steps to properly prime mine after a filter change..
Dog gone! Don't blow compressed air into fuel filter, et al (back into tank!) -- that explains a lot regarding my mower! Good tip!
My pickup tube had fallen off before i got the machine, it's a 7753, so i just have a 2 gallon tank hanging off the side, so there can't be much fuel that returns back to the tank or my tank would be over flowing and i don't see fuel on the ground, but i need to fix the pickup, i have watched other videos where they fight the grommet back in the hard way and it put me off, thanks for the video, now i'm inspired.
Great video.
Able to fix my 873 on my own.
Hydraulic cylinder fix next, using your video.
Thx so much!
Great video! Now I won’t ever blow air back into the tank again thinking I’m clearing the line! Ha, ignorance is bliss right? Thx for another education.
Excellent video! That's my problem, from blowing compressed air on the tank to unclog that tank filter.
Great video and thanks for posting....quick question, if the engine won't start what is the best and safest way to raise the arms so you can raise the cab to get to the fuel tank. Thanks!
