- Now that we have gone through the majority of the fuel system on this machine, it looks like we're headed into another Fuel Injection Pump on an old Diesel engine!
This is a Denso pump which is very similar to a Bosch VE pump, but these are a BIT more complicated than MANY of the others I have repaired in the past, so I guess we'll see how this goes!
Sit back, relax, and enjoy everything we have to do to work our way through the fuel system and try and figure out what is causing this old Gehl to run SO poorly!

The Area Diesel Service guys are some hustlers. I like those guys. They get in touch with all the UA-camrs that work on diesels and use them to promote their brand. Those guys work their tails off.
I’m just in awe of your intrepid nature. It’s a genuine moment when you tell your audience that you made a mistake. Anyone who’s taken things apart will go through that moment for sure. Really enjoy watching your tear down / rebuild videos.
Can we just take a minute to think about the people who designed this pump, manufactured the parts and built it, all from scratch! Boggles my mind.
Those people were wizards. Nothing less.
I TOTALLY agree!
The original design of this pump was also most likely designed WITHOUT the use of computers... THAT makes it even more incredible!
@@SalvageWorkshop what you need is a ultrasonic cleaner not a pressure washer ;)
Great work Matt. Striping it all down and giving it a shot. The mystery continues.
Love watching your videos with the commentary.
I'm sure yourll get there.
Europeans and Japanese surely are the pinnacle of technology amongst human race. you can be sure these type of technology will never come from wakanda
I would like to thank you and other UA-cam's that put out videos like this. I just wish UA-cam had been out around when I was younger, because there's so much a person can learn by watching videos like these. Again, Thank You
So, here I am; a guy who sells wine for a living and I'm spending an hour + watching an injection pump rebuild and loving it. A testament to your ability to keep your viewers engaged, no matter the length of the video or its subject. Can't wait to see you getting this old machine running true again. And dare I ask: how's Red?
i agree with you
Cheers
Gotta hand it to you, you are not afraid to tear into pumps, engines etc. Heck of a good way to learn. Best of luck on this.
Lol... well worst thing that could have happened was not getting it to run, and we would be going to Area Diesel Service then too... why not give it a go!
Now I know a lot more about this machine, engine, pump, and can use that knowledge to help with whatever else I tear into next!
Incredible, that the guys from Area Diesel Servive actually offered help to you...I can't think of any other shop that would do that...really nice!
Thx a lot for taking us with you on this ride!
👍👍👍
If I was in the US, I know who I'd send my gear to.
The fact that any gas or diesel powered engine actually works is truly amazing. The complexity of every subsystem, and the tolerances for things like this. Just amazing.
Electric motors and the control systems are so much easier to understand, and so many fewer parts!
It's no wonder the first cars were electric!
That linkage flip!!! I tell people I train that mistakes are sometimes a gift. You get forced practice which costs time, but at least you gain the experience. Murphy knows just when to spring his law on you though.
I didn't know what I was getting into when I started watching this channel.
All I knew was these guys broke their brick wall.
Now suddenly it is one of the best DIY channels on UA-cam. I'm glad I found it.
You have the courage of a Spartan warrior to tear down and reassemble that fuel injector. I can't wait until your next episode!
Taking apart, no problem. Getting it back together correctly is my problem. 😂
Your not alone there...😂
This is one of those moments I look at the pump as I take it apart, apply lube to my rear end and take the pain of paying a professional to rebuild it or buy new. Kudos to you sir for the bravery.
An old machinist I befriended showed me a way of wrapping shim stock around weird shapes before using a pipe wrench. He literally used a strip cut from my Dr Pepper can, wrapped the odd fastener a couple of times around, pinched it in several directions with slip-joint pliers, then put on the wrench. Messed up the "shim" but the fastener was untouched. He also did not hesitate to modify Craftsman tools because 40 years ago Sears would swap anything.
I like the shim idea... I have plenty of cans around! I'll definitely have to give that a shot, thanks for the tip!
Gee, then we wonder why companies don't warranty things anymore
Thank you for doing this video. I haven't actually seen anyone film the entire process of building an injection pump. This was very interesting.
nice to see someone else that likes fire engines and construction toys like me! when i was a kid i played in the dirt with my toy road graders draglines and what ever else i had for hours at a time.
You and I are a lot alike. I taught myself to work on engines by rolling up my sleeves and getting my hands dirty just like you did. Engines aren't as scary as people make them out to be. I recently started filming content for my own channel doing small engine stuff, and my goal is to show people that anyone can do it if they are willing to do the work.
It seems a problem makes you jump thru the hoops by the numbers before you can an issue resolved completely. The good thing is when you do get the issue resolved, your going to have a nice little machine to work with and one boat load of experience. You can’t beat an experiential education, nobody can take it away from you, thanks for the tag along video young man
Drink every time you hear Area Diesel Service, good luck. 😀✌❤
Always a pleasure watching and listening to you. Learning a lot from your systematic analysis and problem solving skills! Thank you!
D24 typ
You are a brave young man to tear that pump down. I would never attempt it myself.👍😀
I was riveted to the screen. Waiting, wishing and hoping you had it. Smoke and acting like full choke on a gas engine busted my bubble too. I almost can't wait for the next video after seeing the HELL YEAH at the end!
Great videos! I'm on this 3rd video about this Gehl and I'm so invested, as you explain what you're doing I'm nodding my head in agreement!🤣👍 Just having a good Saturday morning watching you repair this Gehl!
Wow.... Nothing frightens you! Good job!
The thing I like best about this channel is its genuine. Great series on the skidsteer too.
You boldly go where I fear to tread!! To many small pieces to remember where they go great vidio thanks for all the hard work.
I'm from Poland and i work with cars for a living for like 4 years, and i watch US equipment channels from like 6 years. I find messing with equipment simpler than cars fun to watch and i swallowed all the videos from multiple channels.
This is first time i can see part widely used by EU cars manufacturers on this kind of channel C:
Great series, It'll be great to see it running with out smoking again.
Hey man as far as messing up the direction of that piece from the governor and having to backtrack., I always say if it's worth doing once, it's worth doing it twice! It happens to ALL of us..
edit: 1:25:45 front main (the timing cover seal) and yes it IS a good time to do that seal!! This is a great episode, really getting into that machine and she's beautiful. Hate the she's so smokey, I sure hope it's off by a tooth or 2 on the timing. Still not done the episode yet!
Everything happens for a reason, nothing is for not, always learn from what you do....Thanks for sharing!
Woah - props for working through all those special injection pump fasteners designed to keep Shade Tree Mechanics out, and getting the pump back together with no leftover parts. It will be interesting to hear what they find.
Great video! One of the things to look for is vane wear! I have taken apart gasoline fuel vane pumps that have a loss of pressure to find the vane edges are ever so slightly worn. The fix is to flip the vanes over to the unused side this presents a new edge to the bore! This procedure has worked for us in the past.
Definitely enjoy these feature length videos!!!
Well done for giving it a shot, thats how we learn anything new.
I love when you repair things and figure out how it works.
Matt, I'm very happy to watch you go through that fuel pump, but a man's got to know his limitations. So that's why I would. send it to area diesel so I wouldn't screw it up. You do good work, my friend.
I've been waiting to see this video since last week. I'm about 28 minutes in, you've got the unit almost totally apart, just removing the final eccentric fuel pump section out of the very insides. It's an astronomical amount of machining that goes into that fuel / lift pump on the skid steer.. to me it seems way WAY overengineered, but I suppose us gasoline mechanics just don't get the HD diesel life : ) Great video, thanks so much for sharing, I can't wait to see how it all works out for you!
More parts in this pump than in my entire drive train. The future is bright.
Watch that beard in those timing gears bro! 😂
Seriously though love your tear down videos, I’ve been a mechanic for 27 years and I still keep learning from things like this. Keep up the good work!
You have a hellofa good presentation.
And you have a hellofa lot of tenacity.
And you have a hellofa lot of knowledge.
Good on yuh!
Dude - right on.👍👍
*Well that was the best tutorial of how to pull it apart and then put it all back together. Roll onto the next video... with a lot less smoke aye*
Always admired your tenacity. You hate to be beaten and give everything a go. If I started that project. I would finish up with a box of broken parts and a hole in the wall where something got launched. No doubt it will all work in the end.
Lol... ive been there too! Thanks for the support Dave! I truly appreciate it!
Well Matt props for even going into that pump.Just the engineering and manufacturing of it makes my brain 🧠 hurt .😂
Looking to the next vid.
Thanks Matt
I really admire your patience, I think we're very much the same in that we like to know why something isn't working and will try everything we can you get it right before we have to call in the experts. Looking forward to the next installment Matt. 👍🤗
opening up a can of worms and keeping a sense of humour is one of your qualities well done
Gehl and Isuzu diesel Denso Japan are excellent quality some of the best .
👍 Excellent channel
PS That Denso starter and solenoid is on my New Holland skid steer .A 6.5GM diesel uses same only nose cone and drive is different.
Dealer wants $750 versus $50 at junk yard.
I found one of the brushes stick from rust low power to crank motor.
Also Injectors may be worn dribbling not spraying pattern low pop off to much fuel
21:00 "Not meant to be gotten into by..... me." Yeah, they should have tried harder!! 😂 In my experience, there's no such thing as "customer proof", it just comes down to how much time you have and how badly you want it open/off/undone!! I'm glad to see you value the same rules I like to follow 😂👍👍👍👍👍
Pretty damn impressive work so far!!! To dive in, head first, KNOWING that you're not really familiar with the pump speaks to your mechanical knowledge.
It's very cool to see!! 💪👍
I really like,that you first tried to fix it on your own properly. With your skills,you might should always try it that way. It is also nice,that you know your borders and bring what can't be done to some specialists. Thanks for your video!
Mate, you do good stuff. LOVE your t-shooting logic. Definitely want to see what they found!!
Well that certainly was deep into it. And you are still finding issues yet another great installment on the Gehl series.
Love your videos Thanks for taking the time to bring us along
The outer felt on the seal is considered a dust shield. I like how you go deep into your projects. Without challenge there can be no change. Peace
excellent video, your knowledge and patience is astonishing
I think a compression test would be a good idea if that is okay then it’s a pump or injector problem
You will see that in the next video!
@@SalvageWorkshop or air intake problem
Fuel contamination , sediment and blockage is normal for any engine setting for long periods .
Defiantly made for great viewing bro and thanks for letting us follow along on this. Safe travels
Great entertainment! Reminds me when I took apart my dads stuff just to put it back together again. If I couldn’t get it back together before he came home he either showed me how it’s done or gave me some with the little broom that comes with the dustpan. Daddy roulette.
My God man what a set of kshones, there is so many working parts.
I did all my own mechanics cause I couldn't afford anyone in the shop.
You sir have my complete respect,plus you have the patience 🙏 to explain what your doing.
Fan for life.
Nice job, altough not the result you wanted, but you and everyone can learn about this video. Keep up the good work. The boys at Area Diesel Service will show us what was "bad" anyway.
I think the problem could be those injectors maybe they need new nozzles or they ar stuck Open bc of grime or dirt, like always is a pleasure to see your videos it's awesome your encourage to tear apart all of that i wish You the Best luck to make it work flawless again
I bet it's both, worn injector pump parts and worn out injectors, we will find out🤷♂️😎
Thank you man, i learn so much from your videos - had no clue diesel injection pumps are so complex - even if i manufactured some parts for it in the past.
Hang in there you will get it thank you for sharing this six stars
More nerve than me to tackle the injection pump. Respect
I enjoy watching and listening to how you explain what you are doing.
wow you have the patience of Jobe. Great job although sometimes the Pro's have to be utilized. The end result is very rewarding.
I can't wait for the next part.
I like the way your videos are shot. Everything is really clear to see.
I learn a lot from them. 👍
Greetings from the Netherlands🙂
I don't do this type or work. It's nice to learn from masters of the trade. You are the man!
Very well narrated.
I admire your bravery to get into things u dont know about
It maybe didnt work this time but u learned a lot and so did we 👍
To help with the starting Id be checking the glow-plugs for operation first, remove the bar or wire across the top and check each individually with a hotwire or out a meter across each one. If you put a meter on the rail while connected it will only show if power is getting to the rail. Timing 100% needs to be checked using the dial type timing tool inserted into the rear of the pump in the large head-plug. Injectors would need checking too. Been rebuilding those pumps for close to 40 years now. Great lil units. Biggest issues are front seals going hard, o-rings going hard thru use and addition of useless fuel additives, advance pistons sticking, press reg vlavles sticking. And that large plug in the head of the pump comes loose and engines get very very hard to start. Tightening them up can and will help but they seal on a knife edge internally and really are a one time use part, but insaying that fir customers with not a lot if money they can be re-used but pretty much only one more time.
Or, all four glow plugs can be tested using the parallel resistance formula of Ohm's law.
True but on that Mitsi/Mazda based engine it would take all of maybe 1 minute to check all 4 plugs while still in the head with the rail removed. Being a 12volt system those glow plugs could range in operating voltage anywhere from 6volts to 11-12volts. Touching them with a 12v hotwire is 100% foolproof. If that Skid steer had been dropped to me first thing would be crack inj pipe nuts to see if its pumping fuel. Then check glowplug power supply then operation, check tappets, then pull glowplugs for cold compression test, then injector removal and testing then Id tighten the head plug on the pump to specified torqu and check its timing thru the same plug. And if it passed all those tests the pump would get slipped out. When he fired it up after the pump was installed it knocked and belted out white/black smoke which mightve been air but the white smoke is more likely to be compression or a timing issue and the black is more indicative of a faulty injector/s. But one or more dud glowplugs will cause same issue. It did sedm to clear uo a bit the more he ran it and the only yhing that can change there will be cylinder temps so compresdion may be low. Probly looking at a combination of minor things causing the issues.
Glowplugs, compression, injection timing, faulty injectors.
Well done!
Great video. Love your approach, you don’t have the exact fuel pump tools, but you find a way. Process of elimination to to getting this fixed. Good job.
It is such a pleasure watching you tackle any and all challenges and projects. Thank You so Very Much 😊
I appreciate your resourcefulness. I, like you, try to do it myself. Sometimes with a little help from others.
amazing piece of engineering
years ago I worked for a used tire shop and we had a Gehl skid loader that we used to load old tires into a trailer. It was an early 90s model, not sure the exact year. It had that same injector assembly on it also. it always had problems whenever we would pull it out from winter storage. My boss would just take the injector assembly off, hook it up to a car battery, and with some fuel lines he would pump STP fuel injector cleaner (red bottle) through it. after running it through for about an hour over & over, it ran perfect for the rest of the year. We never had to disassemble it at all. But I bet yours might be more of a mechanical issue rather than a gumming issue.
Excellent really enjoy your repair journeys a favorite channel of mine
Great video, I enjoyed every minute. I am looking forward to the next one
ADS are great guys.
Denso and Diesel Kiki injection pumps were made under license from Bosch. That's why they look like the do. Bosch owns 5% of Denso. Diesel Kiki was renamed Zexel in 1990, and was eventually bought out by Bosch in 2000. Kiki was made under license in Japan since 1939.
I just love this guy 🤩👍🏻🏴
@11:34 I think those are "retractor valves" that cause the pressure to drop off the fuel line quickly as the pressure starts to fall when the injector pops. This prevents the injector from dripping fuel that is not well atomized in the cylinder when it fires. If that valve failes, a cylinder should give you a little black smoke all the time. If you are running the engine, and you have some dark smoke, crack the fuel lines one at a time to see if comes from all the cylinders or just one. If it is just coming from one, then look at the retractor valve first. That is what you would do for an inline pump.
Hey Matt, even though you couldn’t get it right, I really enjoyed the process! I’m even happier that we get to see “the professionals!” You have to think that you’re increasing the value of the machine anyway. Thanks a lot, great series, appreciate it!
You are one brave man taking that pump apart - and you got back together as well ! I keep thinking the way it ran fine one minute but smoky the next should help pin down what might be causing it. Had a friend who struggled for ages only to find a small casting flaw had broken through and allowed a water heating passage in his inlet manifold to leak into the inlet tract causing a lot of steam out of the exhaust. Maybe pressure test the cooling system again ?
Area diesel service are good people fs , hope they get it all fixed up for ya 👌🤘
I do admire you if tried to take something like this in parts would be all over my shop.
a-ha! now i know what you meant further to my comment on a previous video about you working with Area Diesel!!!!! it's good though to systematically work through the obvious before spending the money out and look forward to seeing what the guys find
I enjoy watching your videos, seeing the process of getting things done, the holdups and the success. Time well spent! Thanks 👍
Thank for creating these video.
It looks like at the very end that you managed to get this problem solved... but I hope you do a follow up video. It is really easy to get discouraged when you tear everything apart and nothing jumps out at you as an obvious cause for the problem... so I gotta hand it to you that you stuck with it and asked for help when you needed it. I am eager to find out what the final diagnosis was and whether this problem is truly fixed now. I was trying to figure out how and why you have been so certain that it is a fuel delivery problem. I wouldn't know to rule everything else out... seriously. Anyway... this was grueling... and I thank you for sharing this with us. Something to think about the next time we get discouraged with one of our projects.
Great Job - you have confidence to pull apart such a complex pump.
Thank you for the cool video, Eric!
I enjoy your in depth videos. Good job tearing into issues trying to resolve them yourself! 👌👌
Another great and fascinating ride along video for us. Never had a doubt about your ability to figure it out.
I’ve watched every video over the last month😳. And think your channel is such an inspiration and enjoyable to watch. Love your tool restorations so keep them going. Machines are great also. Keep up the good work👍
Wow! I truly appreciate the compliment Chris, it means a lot! Glad you enjoy the channel, lots more to come!
Love watching the videos. So informative!
90 minutes again. I'm not going to sit through that long.
100 minutes later: I think I missed a part. Let's wind back again.
I'm addicted.
LOL.... I appreciate that you enjoy the longer videos! Thanks for watching & commenting!
Great job. Enjoyed every second of it !!! 🫵🏻💪🏻👍🏻
Great job , amazing patience and perseverance .
Very tight tolerances involved which makes it a good idea to put down some clean cardboard on the bench and wipe down the vise and tools used working on the pump. Good time to use the sonic cleaner. It can be very hard to eyeball the proper clearances that are needed to make the pump work properly so it might be necessary to go on faith and just clean it up meticulously. When you get to ten thousandths of an inch eyeballs can't quite calibrate.
