TRYING to FIX the MAGIC Fuel Box... This one is COMPLICATED! ~ 1995 Gehl 5625sx Skid Loader P3

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!

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.

[@frutt5k]

Those people were wizards. Nothing less.

[@SalvageWorkshop]

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!

[@NurdRage777]

@@SalvageWorkshop what you need is a ultrasonic cleaner not a pressure washer ;)

[@diggiz22]

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.

[@lordjaashin]

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

[@larrydavidson3402]

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.

[@SalvageWorkshop]

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!

[@davidaylsworth8964]

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.

[@jesterr7133]

The Area Diesel Service guys are some hustlers. I like those guys. They get in touch with all the KZbinrs that work on diesels and use them to promote their brand. Those guys work their tails off.

[@robkarnosh117]

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?

[@mariocardamone1846]

i agree with you

[@willtricks9432]

Cheers

[@Cartrik28]

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.

[@cadthunkin]

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.

[@benjaminohloff7819]

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! 👍👍👍

[@KrisDouglas]

If I was in the US, I know who I'd send my gear to.

[@chrisbartrum3201]

The thing I like best about this channel is its genuine. Great series on the skidsteer too.

[@gtnaylor5870]

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!

[@tfatcher]

You have the courage of a Spartan warrior to tear down and reassemble that fuel injector. I can't wait until your next episode!

[@Nordmende01]

I love when you repair things and figure out how it works.

[@BobOBob]

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.

[@SalvageWorkshop]

I like the shim idea... I have plenty of cans around! I'll definitely have to give that a shot, thanks for the tip!

[@giggiddy]

Gee, then we wonder why companies don't warranty things anymore

[@terryrogers1025]

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

[@GaryDavis-ir6fh]

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.

[@jazzerbyte]

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.

[@michaelgardner800]

I would like to thank you and other KZbin's that put out videos like this. I just wish KZbin 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

[@jesterr7133]

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.

[@SciPunk215]

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 KZbin. I'm glad I found it.

[@jackanderson1418]

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.

[@tdtvkc1]

Drink every time you hear Area Diesel Service, good luck. 😀✌❤

[@jesterr7133]

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.

[@larrylane6512]

Love your videos Thanks for taking the time to bring us along

[@alanjarvis8777]

Wow.... Nothing frightens you! Good job!

[@walterwhitaker1395]

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.

[@michaelhess4825]

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!

[@tomasjosefvela1]

Everything happens for a reason, nothing is for not, always learn from what you do....Thanks for sharing!

[@johnnyroberts6291]

You are a brave young man to tear that pump down. I would never attempt it myself.👍😀

[@anthonyblacker8471]

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!

[@T_B]

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!! 💪👍

[@everestyeti]

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. 👍🤗

[@shawnzalewski1917]

Definitely enjoy these feature length videos!!!

[@MichaelSmith-dg3kr]

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.

[@bruceprosser4283]

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

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.

[@anthonyblacker8471]

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!

[@jb_makesgames2264]

Great Job - you have confidence to pull apart such a complex pump.

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.

[@petroshalk814]

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!

[@poprawa]

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:

[@nena4215]

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!

[@HansWeberHimself]

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.

Hang in there you will get it thank you for sharing this six stars

[@rhiantaylor3446]

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 ?
