- It's time for a PHAD farm service call!
This GEHL skidloader turned into a crank no-start shortly after a recent engine swap....and there's cow manure to be scooped ASAP.
PHAD to the rescue!
Enjoy!
Ivan
I have meet this dude. Stumbled across his videos and absolutely loved them.
this was the first skidloader i learned how to drive when i was 8, hearing that starter brings backs memories💯
Thank you for helping your neighbors out. You are a gentleman and a true American
Your investigating skills are intact my friend. That was a great diagnosis.
You are the man! I have the same problem on a gelm 4625 and I am going to follow your troublshooting procedure. Thank you soooo much for sharing. Absolutely excellent video.
Must have been a brand new rebuild, well done. Nothing like the smell of Ammonia in the morning.
Haha... now, now he said it was "mud"
Way to put safety 3rd Ivan!
Hell yeah Eric I knew you would approve xD
Lose one finger, he still has 9 left. :D
That looks like a job well done!
Much easier than working on a modern car, that's for sure! Have room to work!
Nice being on a farm rather than in the city, IMO. Can't beat the sounds of spring. Finches, geese, and redwing blackbirds (must be a swamp or pond nearby) I heard there. Love it.
Never heard of that brand skidsteer before. Those things are little workhorses. Amazing what you can do with one. We did the whole foundation and drainage in my yard here for the shop addition, with just a tiny 6,500 lb. excavator and a Bobcat! Crazy - I didn't think it was possible until I saw it happen. They definitely need that thing around the farm!
Great vid Ivan. Thanks! 👍
thank you . its me , hope you remember me . i met you at TST seminar in NY .
Ivan your so unconventional when it comes to finding the problem with a piece of machinery that's why I love watching your channel and I get to benefit from your diagnostic process. I learn a few things that help me in my own mechanical work.
Thanks alot.
Thanks Phil!
Great diagnosis!! Glad u can still post with new job
Drilled out the pop rivets on an outboard motor starter solenoid one time and cleaned the contacts and it stayed working for years. Don't know if that would have worked on this or not. Great video and diagnosis.
Interesting diagnosis!! But I've never heard of the that plunger pulling in once you start. But I learned something in this!!! I think it's sad for me as I didn't work or learn on Kubota diesels, as when I was younger, we had Ford's, Rover, Peugeots, Citroen mostly etc. Since you know I'm from England!
Great job. Your an excellent teacher.
Very cool Video Ivan. Great testing on this and as always something interesting to watch.
Nice diagnosis Ivan...you definitely run the gamut!
Now that's different to the vehicles you normally repair, simplicity is nice for a change :-D.
I'm sure it worked like a champ once you replaced that double coil solinoid.
Logically the higher resistance coil is the hold in.
You do look like a Ninja now :-D.
Ivan, you are a diagnostic beast! That was a fun one. Thanks!
way to go Ivan. excellent diagnosis man. you're #1
🤤🤤 I need to see this on the whiteboard 😁
Nice one Ivan. Thx 👍
I quite approve of the ninja cow lot diesel doctor look!
At the beginning of Winter, check cars for codes and ALL important systems to prevent trouble during the freezing Winter. Do tuneups and oil changes and other things to get them thru the Winter.
Ah the old fuel cutoff plunger!! Crazy how tight that is in there. At least its not in sideways like a Bobcat!! Now you can add "diesel" to your knowledge base!
You are awesome!!!
Another well thought out video. Sounds like spring has arrived there. Snowed 2 inches yesterday here. Tired of it.
Should be balmy next week :D
Ivan I am proud to say I bought that same amp clamp and its great. The L.e.d back light stays on when you press the button. I take it on the road with me. It was becoming difficult to find that meter in the store's. Found mine on craigslist.
Cool! One of my favorite tools :)
You are amazing! And that's the exact solenoid I have on my cat excavator. Now I know how to test it. Thank you!
You do great work down the farm Ivan :)
when key is on run/start, the hold coil should always have power! "key start" supplies power to the pull in coil, that is when the solenoid actually opens. So a low/weak battery or out of spec. coil may not pull in when cranking(chinesium!) bad connection, wire, weak ignition switch or relay could cause low current and no pull in also. just things to keep in mind :)
Nice job "Farmer Ivan"
as soon as you said engine swap i knew what was going on. willing to bet they got a wholegoods engine which is less expensive. they typically are the same base unit yet the "accessories" are often configured differently. then i seen the old sollenoid. that one was set up for an external bracket and linkage that operated an arm on the governor cover not an internal one like that engine had. when swapping those engines EVERYTHING that is not identical needs to be swapped over. those pull in coils are notorious for frying if juice is applied for too long of time. most likely the original was a gehl part not kubota. it could be that the original engine configuration was no longer available. but still everything needs swapped. just because a pigtail fits doesnt mean its right lol
I deal with that engine in trailer refrigeration units and get that problem from time to time, it shorts out the pull in coil and normally blows the fuse. the old engine that came out was a older model that had the kill lever external
NICE VIDEO IVAN, YOU SHOULD BE TROBLE SHOOTING FOR NASA. KEEP THEM VIDEOS COMING.
You never know what ya gonna see on your channel Ivan 😂
If you cut that solenoid apart you'll see a set of contacts on the pull in coil.As soon as the coil is energized it opens the contacts on the pull in coil to keep it from burning out.Power is maintained on the hold in coil until you turn off the key.Iv'e burnt out two of these coils and haven't found the problem yet.For some reason the contacts don't open on the pull in coil therefore frying the whole coil.I have a fuel shut off cable on this machine so I'm using that to stop it for now.Anyway from one gear head to another keep the videos coming Ivan.
I was just looking at a 2015 TI paper on 'Detection of Plunger Movement in DC Solenoids'. They were proposing a relatively simple circuit that detects the solenoid current peak and valley to sense the plunger movement and then possibly use that to reduce to a hold current rather than have separate coils. It would remove the hold circuit in the video. And of course, offer up a nice electronic failure point in to the mud and muck environment. This circuit didn't use a computer but it could be something the ECMs start monitoring.
They used to have a mechanical cable which was even less failure prone!
Great Video Ivan
Thanks for the comment :)
Nicely spotted.
Use De-Oxit on bad solenoid, then retest. Might get the loader back to work while waiting for the new solenoid, which may be back-ordered for weeks, if Murphy’s Law is still in effect in your locale.
interesting diagnosis. thanks
This may be a bit off topic but, you look like Jaqen H'ghar from Game of Thrones. Oh yea, by the way, thanks for the video.
What do you NOT work on?
Excellent video brother : )
Just like a GM starter solenoid! There should be a three wire replacement solenoid or an adapter to go from three wire to 2 wire and external case ground. Part 2 coming?
You're called out to service some of the darnedest equipment -- cherry pickers in the Midwest, a skidloader on a farm, ...
I doubt that Eric O. ever deals with stuff like this. His exotica is limited to the occasional snowblower.
I worked on heavy equipment for 7 years. Lots of skid-steers, dozers, loaders, dump trucks, excavators, tractors, backhoes. I just choose not to these days....
I stand corrected. Your shop is so full of cars nowadays -- and you seem to have such a detailed knowledge of them -- that it's hard to imagine that you ever worked on anything else.
It wasn't so scary for us as it was for you, since the Hero usually turns out OK in the movies! I wonder if the original solenoid could work if the mounting holes are enlarged?
What would your guess be if I don’t get the engine trying to crank but battery is good and it was starting fine. I can hear something behind me on the left side clicking when I turn the key. It kind clicks with the key as I turn the key on it clicks and when I let the key go it clicks, but no fire. Not a mechanic 😕
The test light... where can I buy those connectors (the red ones). I want to make those!
Great video!
so what was the thing that was wrong? and why did it run after if that was removed?
I work with reefers and Thermo King has the same solenoid and every one I have changed have failed on the pull in coil. The hold in is fine and if I don't have a new solenoid I manually push it in to get the unit started and to make the unit stay running I manually tell the controller to not shut off the engine when it reaches setpoint. The new solenoid from Thermo King is $170. It is a little more tight spot to change compared to that engine though.
I have a GEHL 4840 SKIDSTEER it’ll start but then the next day it won’t and this only happens in the winter then when I try again a week or two later it’ll start and then the same thing the next day it won’t start do you know what the problem could be let me know thank you
Where was this ? I live in Spring Mills right outside state collage dude
Ivan had to laugh when your car was full of smoke....
I have a 332d Jd and I clean the air filter while engine running when I put it back 10 seconds and it died what could it happen....help
You are like Dr. Pol but for vehicles.
I gess there is normaly closed switch inside for pull in coil like on starter motor. maybe bad contacts on that switch.
I tried to be first....typing one handed slows me down!
Take it easy :)
HA! 🤣
Spoiler alert. It wasn't the distributor cap.
+Vladimir Putin editing footage for the next vid, of course ;-)
quite a DIFFERENT unit-so your diagnostic baffled me
-will new assembly be better? or will another different unit with H/D form "C" switch work?
What if all I hear is a click and no crank at all? Starter?
Since there are no spark plugs on a diesel ( just glow plugs) there has to be a way to stop the engine. Fuel is normally off at the valve so to run the coil pulls and lets the valve open. Ivan reached in and manually pushed the valve closed to stop the engine.
I have a John Deere 312 GR and I’m trying to replace the starter because it gives me a error can you help me
Good fix, wondering what the cost of the new solenoid was, Kubota is usually pretty proud of their parts. I own 5 of these engines in older machines. Wonder what was wrong with the old pull out kill cable? Everything has to be so convenient anymore. I bet my cable cost a lot less than the double coil solenoid, even sounds expensive huh. Hope your new job is going well.
Old cable was much more reliable for sure! It's all about the safety cutouts these days...
Mr Fix it !!!!!
Those things are difficult to work on. Doing a starter on my JD. Nightmare. Too much stuff in too little space.
T1740 getting fuel but don’t run where is the senior location
Hey Ivan, if the new cutoff solenoid with 2 wires is wired to the old 3-wire controller/switch assembly/wiring harness, how sure are you that it's wired correctly? Could it be that Pullin and Hold are swapped around? Normally, initially both go on, then after starting the controller releases Pullin but keeps Hold activated. But if those are swapped, it'll start OK, but then it will release Hold while maintaining Pullin. It looks like Pullin is designed with a built-in limit switch to kill the pullin circuit when it reaches the Held position (normally to be held in place by Hold). So with the swapped wiring, the overall effect will be that the solenoid will oscillate between fully pulled (opening the limit switch) and slightly released enough to close the switch and pull it in again etc etc. Hence buzzing, and an extreme workout that might have messed it up -- eg messing up the limit switch.
The wires matched up fine if you look at the plug. Must be made in China haha
I think you're saying that the connector was mechanically a fit? Question: You report that When working, the new solenoid buzzes -- why is that, and is that as intended? I say it should not buzz, and that the improper buzzing indicates that the wiring harness/controller is continuing to activate the Pullin circuit instead of the Hold circuit.
Zip tied The fuel shut off open till it starts to verify
can you help me with my gehl skidsteer
im trying to get it running
What does that solenoid actually do? How does that system work?
It just disables the high pressure diesel pump :)
Bobcats are so much nicer to work on
U look like your going to have a day with the navy seals,😂
If the belt catches your finger you likely will lose all your fingers, not just one, as the one will pull the others through, if not the whole hand. There was a guy who was at the auto part store almost every time I was there, and that is what happened to him. All he had on one hand was a thumb. The sight of his hand was enough impetus for me to never try something so risky. He could still work a screwdriver with the palm and thumb.
lol you look like a ninja its great. auto diag. ninja.
I THINK YOU ARE LIKE I WAS WHEN I WAS YOUNGER AND IN THE CAR BUSINESS ,ONLY NOW ELECTRONICS HAVE CAME A LONG WAY . ITS GOOD AS LONG AS IT WORKS. IM SORRY IM BACK FROM DECEMBER WITH MY ISSUE WITH MY 2009 GMC 2500HD WITH THE OVER CHARGE QUESTION. I JUST HAD ANOTHER BATTERY INSTALLED LUCKILY UNDER WARRANTY. I THINK IT BOILED THE BATTERY SINCE DECEMBER I HAVE A DIGITAL VOLT METER IN MY DC OUTPUT IN MY TRUCK AND IT NEVER GOES BELOW 14.5 VOLTS. ITS ALWAYS ON 15-15.3 WHEN STARTED AND EVENTUALLY DROPS TO 14,5. FOR SOME REASON FROM WHAT I HAVE RESEARCHED THAT IT IS IN CHARGE MODE ALL THE TIME WHICH GM SAYS IS BETWEEN 14.2 TO 15.5 MY TOW HAUL WORKS JUST FINE.EVERYTHING IN THIS TRUCK WORKS FINE. I REALLY NEED SOME HELP. I WISH YOU JUST LIVED DOWN THE STREET. YOU REALLY KNOW WHAT YOUR DOING. ANY IDEA. FRUSTRATED GARY C.
Hold in coil next to a nut buddy video, SHAMELESS.
One more time......the black label was labeled what ?
Mud with Cows :)
Boy, That was a tough one. NOT. Good thing you do not work flat rate.
Anyone know where that loader was manufactured?
Ryan Kennedy In a manufacturing facility somewhere in this world would be my guess. Lol....
Soux Falls SD
JerseyBoy 34 Probably not in Sioux Falls as they don't manufacture them here unless someone's setup shop here lately. Yankton S.D. has a plant for Gehl loaders and other stuff.....
Dale N
The 25, 35 and 40 series were manufactured in Soux Falls during the 90’s and early 2000’s. I attended dealer training back then at the plant.
Mess around and loose a digit reaching in there
🍺🍺🍺🍺🍺👍👍👍👍👍
Safety third
Are you special force where is weapons 😀
"Let's think safety"??????? What would be the fun in that? Losing a finger would make your video go viral. :)
Had to switch off the video, the whiff of fresh cow dung was too much. Hope the diagnosis went alright and ye was'nt gored by a bull.
Bypass it is faster
