Bobcat T770 Hard Start and Runs Rough. Troubleshooting and Repair

[@oiu7890]

The net use to be the info highway today it is sell you something or a waste of time highway!🤬 I could say I love your channel and I do further more I truly respect and find I learn at least 3 or more tips and use full info from each video on your channel . No wasted time petting animals or screwing off. The back ground skit of the boy drinking and walking off with the pot of diesel was great but it did not waste your or my time!🙂 I do not know who or why your are being censored I have not seen or heard any thing that would warrant it. Please keep up the GREAT videos. You tubers should learn from you how to make useful videos! 🥰😃 Your Tuesday evening tec talk is a favor-et of mine. Many question and answers I would not think of asking or looking fore.

[@jamesbailey7785]

What was the company name and where did you go to for laptop rental ? Tom

[@CenTexAg]

What program and adapter do you use to reprogram the injectors? Is it available to the public? That would be a great informative video 😉

[@CTSCAPER]

You make it look so easy. Thanks for sharing.

[@JohanKlindex]

This injector backleak test have help me many times. Very easy to do at field. Even if you dont have tubes with you hehe

[@KarasCyborg]

You a legend Brady! Because of the computer work, I don't think this is a DIY job. Since you had the whole thing apart, any reason for not just replacing all 4 injectors for peace of mind? Any way to have them rebuilt?

[@arcticmining23]

Great to watch you work

[@jeffmaclean7700]

Thanks for the great video I have 4 of these machines ,I’ve had to of these break scr straps and bracket hold down bolts

[@pawwaw2730]

Thanks alot, this kinda information helps alot

[@stevec4011]

Also I understand the reason for coding however if the ecm will eventually learn and adjust to the coding of new injectors I don’t see why that is mandatory or why it would cause any damage but I will take your word for it and code them.

[@Heidenryk]

I have a 863 bobcat, the do you have any videos on replacing those

[@andymora5595]

In which cases it is possible to clean and reuse injectors and in which cases they are destroyed? Does diesel engine cleaner which you put in tank really helps ? Would be a good to see a video for learning everything about injectors 😊

[@Saidi-zd3ot]

Can i cut off the high pressure line for rotary and inline injection pump or just this method used in common rail fuel system

[@juanfgonzalez2039]

On a bobcat t650 what would cause the injectors return line to build fuel pressure 🤔 and lines popping off when cracking and the line going down to injection pump on the return line

[@thomaslecour2462]

Hello I’ve watched your videos and am a big fan of yours in guidance to my bobcat equipment. I work on most of my equipment but I’m limited in knowledge. My machine is passing a code of m4404 2021 A770 with the MaxControl and I can’t connect to my iPhone now I used remote a month a go with a mulcher attachment since. If I disconnect the MaxControl I get no code and runs fine I’ve checked fuses, relays, and plugs directed by Dave Mokena Illinois service dealer What am I missing

[@NickCoppola-rd8qu]

Would you have to test the fuel system for any more contamination? Maybe why the injectors went bad my machine had the same problem and the Mechanic had to test the contamination of the system which was condemned bad so they had to replace the entire fuel system.

[@popeofwrenching4357]

That’s a nice gravy call .. $2400 worth of injectors alone .. gotta love doosan

[@Dirtdaddy953]

Just replaced all 4 of mine on my T770. Bobcat wanted $1050 a piece for the injectors. I found New OEM Delphi’s at a place in CA for $450 a piece. Shop around before you head to the dealer.

No fault codes showed in the monitor for this hard starting motor

[@ozarkarky]

So how do we shade tree mechanics reprogram the computer thingy after changing an injector?

[@tetradgroup]

Laptop rental or dealer can program for you

[@ozarkarky]

@@tetradgroup nearest dealer is 2 hours away (one way), but I have a laptop. How can I do it with my laptop?

[@MHolt3573]

I know it's not recommended but it will crank and run without reprogramming.

[@andyloebrown8250]

​@@ozarkarkyyou are going to need some special software on your laptop and possibly a special cable

[@Dirtdaddy953]

If you need to replace the injectors do some shopping around. Bobcat wanted $1050 a piece. I found new OEM Delphi’s for $450 a piece.

[@jrac863]

yup electronic injectors nothing but trouble.They need to get rid of common rail and go back to mechanical injectors.
