- Bobcat with Doosan D24 is hard to start when cold so we are going to do a compression test on the cylinders and also check the glow plugs and glow plug circuit for proper operation.

Thank you for producing a very well done video series. Camera work, narration, easily understood explanations are some of the best out there.
Best machine videos on TH-cam. I enjoy them , thanks for the work you put into making them
Love your workshop/lab and vital second test
Ohmd my plugs a couple days ago and they were fine, I will pull them and power them up to verify. Thanks!
More useful information. Always a joy to watch your videos.
This guy is awesome, the shops have become too expensive.
Thanks so much! Your videos are great. I have a T595 and your channel has helped me immensely
I actually have this same kit for my mt55 engines. Now I just got a 2015 t590 but it's only 1600 hrs and runs great. It's a little hard to start in 8 degrees but it works.
Excellent video and content! Thank you for sharing your knowledge and time!
Great Tutorial!!!
As always Master doing what does best !!!
Thank you for your great explanation.
Thanks , Have a great day
Just great man! Thanks for sharing your experience and knowledge, well appreciate it! 🙏👍
Hey I just want to say thank you for sharing your troubleshooting knowledge. I have always ohm things out it’s not always accurate as you mentioned
Thank you for the video it help a lot...
Wow thats crazy 4 bad glow plugs .How could that have happened.I have seen 1 or maybe 2 on the kubotas but never 4.Great video and troubleshooting.Also I wish the Maddox diesel tester was available a few years ago because I bought the big Pittsburg tester and it does not have 8 mil adapter.Time to take a trip to harbor freight thats a nice set u have there
That was a fantastic video! Thank you for producing it. I can see an awful lot of people benefiting from this “lesson”. I routinely send your videos to guys on the skid steer forums that have that specific problem and recommend they subscribe. You’ve made me sound like I know what I’m talking about when I try to help them through their issues. So I hope I’m adding to your followers. Quick question, will you do or have you done a video on “ if you were going to buy this skid steer, this is what you would want to check”, that would be so useful to a lot of people. Thanks again you are the best! Your parents have got to be very proud of the son they have raised, and I hope you are teaching your son everything you know so he can be your assistant in a short time.
I can't thank you enough for the kind words and support my friend. Thank you for the idea, I have thought about that considering how many skid steers I buy and sell each year it shouldn't be hard to make.
Same here.
You got me with that glow plug LOL
Thank you for the good knolage, great videos, to request on videos, I have T590 Machine is the N series has had problems with the right joystick ,I'll be thankful if you can do a video in this issues.
What would cause a 10.5 volt reading at the glow plugs with a fully charged battery ?
Damn you got me 😂
You really test them the hard way dude.
All you need to know is how many amps each glow plug draws, most pull around 10 amps@12 volts.
So I just clamp an amp meter around the wire feeding the glow plugs.
0 amps they're all dead, 10 amps 3 dead, 20 amps 2 dead, 30 amps 1 dead, 40 amps all good.
Define the dead ones usually all you need is a incandescent test lamp you can tell by the illumination once you get the hang of it.
At what temperature is the block heater needed?
What would cause a loss of pressure while cranking??
Another GREAT video!!! Quick question, Is it safe/ok to use "diesel 911" on common rail systems, D24 ?
In my experience 911 causes more issues with the common rail fuel systems. I really like Bobcats tier four diesel treatment, works best for me in the winter.
What an awesome find on TH-cam! I bought a 2019 t590 this past fall with 444 hours and so far so good. I use it in the winter for snow and so far its been fine in the cold but have a new block heater to install and thanks to the video I found the plug. I do have 2 unrelated questions if you dont mind...After it warms up where should the heat needle be at (mine is about 2 needle widths above the cold mark on the gauge (kind of like the 1/8 mark on a old fuel gauge) and getting good heat. 2nd question, my heater switch has 3 settings and there is no difference in low and med. and when its on high there still isn't much more air blowing out but I can hear what sounds like another fan but again hardly any more air coming out. I've changed the switch and replaced both cabin air filters, any idea? Thank you for these video's!
Question 1- The machine should run at about 190 degrees. Question 2: As far as low air flow, don't forget to check your recirculation filter behind the seat and it is a good idea to raise the cab, remove the cover for the condenser and heater core and use an air compressor to blow out the heater core and condenser. If it is hard packed dirt, you might have to wash it out with a water hose. Also make sure the drain holes in the cover are clear and free of dirt and mud.

What about a hard start on warm days? Same engine in a 2015 T450. Thank you
That is common with a bad injector, sometimes they leak by more when hot
Did you have the link for the adapter?

So do I understand correctly, glow plugs are really only needed in colder weather?
They can be used as starting aid at any time but primarily they are used when its cold outside.
seems odd to me that all 4 glow plugs are junk any reason why that would happen?
It is odd, seems they only last a few years on these machines for some reason.
Ever have an E000731-20 Accelerometer Fault ?
Yep
@@tetradgroup what can I check or do I need to take it in to the dealer ?
@goinsexllc the accelerometer is a knock sensor. They are located on the block below the intake manifold, they are a round sensor with a bolt thru center. You can loosen and retorque to spec. The torque spec is crucial. Also check plug and wiring because it's very rare one goes bad
@@tetradgroup awesome ! It was just in a month or so ago for a whole new fuel system and turbo, got it back from dealer and glow plugs started faulting and then got the accelerometer fault one day all of a sudden !
I appreciate you and your time sir ! Keep the great content coming !!!
@@tetradgroup wasn’t able to locate the torque spec in the manual but have checked the wiring n plugs
So minus twenty it's definitely not low compression your cylinders are probably interference locked to a negative value. And thus compression should be good ... The speed of rotation is lower because it's way tougher to spin harder thus your pump is spinning slower and not activating the pressure valve for you on the rail... yes glow plugs... And if you don't preheat your bobcat or at least engine the temperature difference in-between all the different types of metal wil expand at different rates and thus creat metal.... So please preheat the bobcat. Minus 20 yikesss
So are you sure Mercedes is 4 volt lol I'd bet it's not.. just saying
