Bobcat Fuel Injection pump replacement on a 763 with the Kubota 2203,

[@RobertJ.Morrow]

Thanks for a clear and detailed video; without any music or frivolous babble.

[@jimkline8080]

I m really impressed with your bobcat videos they help a lot very clear and informative thanks for taking the time to make them.

[@stevea6722]

Excellent explanation describing the finer points with the injection pump replacement.

[@chriscadman5715]

Excellent video. Simple, linear and easy to understand. All injection lines being the same length is a nice piece of info. Thanx!

[@tetradgroup]

Glad it was helpful!

[@jan_phd]

The pump manufactures 'pulses', so the length must be matched to assure phase coherency (the time it takes for fuel to get to the port). It's the same with exhaust lines too. For you radio/microwave people, think of those lines as, 'wave transmission' lines.

[@deano6188]

I reckon the lines are the same length so the factory only has to order/make one line and bend accordingly... money saver. Great vids can learn a lot from you.

[@stevea6722]

Fuel delivery in accordance with equal timing for all cylinders.

[@dmc31405]

Thanks for sharing. That tip about the lever on the rack on the fuel pump being lined up on that notch in the opening and on the throttle linkage, made all the difference in the world in me being able to remove my fuel pump. You did an excellent job of communicating all the important details.

2015 E50 D24 fuel pump and injector replacement. I just bought one last year and followed your starved for fuel video because it quit on me. And yep one injector is leaking by faster than the others when I swabbed the fuel rail came out black just like you said it might. So I bought a new remanufactured fuel system. What tips or pitfalls should I be looking out for before I go after this project? I would like to thank you for all the work and effort you put in to these videos you have likely saved me countless head aches and more than a few bucks so thanks again! And I’ll keep watching because I have an old 743B that just won’t quit but she’s getting tired so well done sir keep up the good work.

[@rubenshartman]

Bless your heart bud, you just saved me a lot of money. I'm working on my welder machine S4L2 engine

[@markm0000]

That was so easy to follow and learn. Thanks

[@bunkvids3861]

Man that does sound smooth. Great video. I always enjoy watching and learning something from your videos

[@shorty48shorty]

your the man! you know what is going on like factory trained veteran kind of way?

[@scottoutram]

I'm doing an injection pump on an S160 and your video was a great help. Thank you.

[@M.R.C.R.]

Very good explication!!! Tomorrow I will have to time my bobcat 753, have lots of black smoke after complete overhaul. I hope it will get it better.

[@davidtown6825]

Thank you

[@guitaristglenmagic6845]

Hi there, We have a Bobcat 825 recently rebuilt the fuel Injection Pump and replaced it back on it though it cranks but not starting yet. There is diesel on both filters, also in both release fuel Pump valves, no yet on the injectors

[@dan-rr8dc]

What a great, FREE, resource you are! My 743 B is leaking at the #1 location. Can I just disconnect the line to the injector, replace the o-ring, and be good? I know there is a small spring under the threaded connection into the pump, so if I'm careful about it's, replacement will it go back together without issues? Guess I'm asking, do I need to remove the whole pump to stop the leak?

[@johnkritikos7450]

Thanks very good information. Just bought one. 763 on the engine it says 1999 series. But the seller told me was a 1997. Will research.

[@SteveDoesEverything]

Very very helpful video.

[@albertovalentinuzzo5142]

Anche se non capisco la lingua, ho capito molto bene guardando il video, ciao e grazie

[@brandongrimsley9581]

I replaced the gaskets in the pump and reinstalled it. I can't get it to prime. The ball doesn't get firm. The motor vibrates when trying to fire it up. Definitely need advice if possible.

[@WatchRichRebuildsChannel]

Great video 👍👍

[@travisdegroote9131]

Does the injection pump rollers run on the can all the time or only when the lobe comes around? Hope that makes sense. I have a 773 bobcat

[@gyffjogofl7676]

That sounds amazing

[@Brian-uh6dq]

How long would that take you if not filming? Thanks for these videos, they are extremely helpful.

[@tetradgroup]

Thanks for the feedback. I can do that job in about 45 minutes, if it's your first time I would say it's about a two hour job.

[@gabrielwillingham1642]

This was actually helpful

[@mrglabs4778]

Very good tutorial on pump replacement. I have a Kubota MX5100 with a V2403. It ran some water in the fuel at 215 hours on the machine and now there’s no fuel out of number 3 delivery valve. Any suggestions? Does it come off the same way with the rack linkage slot as shown in your video? Thanks

[@toddtwenter3242]

The best Bobcat videos I've seen. Thank you very much for sharing....I susbsribed today.

[@markboltz7721]

Great video, I have a 753 series g bobcat and it smokes black smoke real heavy, I have replaced the injectors and have done a valve adjustment but still smokes heavy . Do you think I may need to replace my pump or any other thoughts you may have would be appreciated.

[@leroycastensjr.1930]

I actually bought new governor springs but haven’t had a chance to R&R them yet. I will let you know if that repaired my issue. Thank you very much for your reply.

[@tonydiesel3444]

Whats the problem?

[@toddtwenter3242]

Why have the pump rebuilt? Is there something about these that you don't feel is repairable on your own. We have had a couple apart and just cleaned and put in new crush washers. I "think" they were OK afterwards. It definitely got each pump delivering fuel again.

[@wade7920]

Thanks for all your videos. Super helpful. Have an 853 with 4700 hours. Been my source of income for 15 years. I do most repairs myself unless it’s above my pay grade. 19:32 Just did all three hydraulic cylinders with seal kits, new hoses, & pins. Big job for me. Still finishing it up. My left-front axle seal is leaking again. Second time in about 4-years. Could the axle bearings be causing accelerated seal wear? Also, my injection pump recently is getting all wet. Was dry before. Do I need to have rebuilt or buy new one, or is it a seal kit? Thx

[@victorhernandez769]

Thank you...

[@joshuaphillips1867]

Length of line is the same simply because the injector pump has to displace the same amount of fuel for each cylinder. If they were longer or shorter, pump would have to alter delivery sooner/later and less/more fuel depending on length, thus making the timing and injection pump overly complicated.

[@tetradgroup]

Exactly

[@jan_phd]

Yup. The pump manufactures 'pulses', so the lengthes must be matched to assure phase coherency (the time it takes for fuel to get to the port). It's the same with exhaust lines too. For you radio/microwave people, think of those lines as, 'wave transmission' lines.

[@x.x..x.x]

wonderful. thanks

[@robgrasso1605]

Nice video. That is an easy injector pump install! If you have any tips on the 463 with Kubota D1005 fuel system I’d be interested. I bought a non running unit at auction. Previous owner replaced fuel timing relay and shut off solenoid. Getting fuel to injector pump but no smoke at all when cranking. Just cranks and cranks. Pick up tube intact but I noticed some water in screw in fuel gauge to the tank. Now I wonder if water got into the fuel. I drained the tank and there were bits of white debris and even some ants. I assume the filter would catch some of this? When I drained the fuel/water separator a fair amount of water did come out. I now suspect water got all the way to the injectors and hopefully has not ruined the pump. My plan is replace injectors flush fuel system and then check timing.

[@walterroseboro6763]

I have a fuel issue on a 843 perkins 4.154 suspect bad injector pump do you have a video

[@cueball1591]

Where you located?? I think I learn something. Excited to see if this fix my issues..

[@tetradgroup]

Hope it helps, I'm out of Utah

[@cueball1591]

Oh.. little far..I have everything new on my 337 Excavator, head, radiator, water pump, injection pump , injectors, run real smooth but. No power. Bogs down real fast ..

[@tetradgroup]

@@cueball1591 typical issue with the 337, your engine may be a little low on power due to age and the hydraulic pump torque limiter needs to be adjusted accordingly or the engine will bog down and feel like an engine problem when it's actually a hydraulic problem.

[@cueball1591]

You got me? Have no idea where that is?

[@cueball1591]

It was doing great till I ran it hit and crack the head. Under a load blow black smoke a lot..

Do kabota injectors leak fuel in cylinder when sitting overnight hard starting first thing in the morning then run and start fine the rest of day glow plugs good can't figure out what else could be

[@bradleyscurrie1209]

Great informative video. Thank You!

[@albertoybarra3388]

I replace the fuel pump on a 2019 bobcat t650 but I wanna make sure if that pump has to be in time?

[@ealtherr3]

I've got an air compressor with a Kabota V1702 engine that needs a new injector pump. Is the installation the same?

[@norvellabente-desabajabuil3289]

Can you help me pointing where can I find the plungers ? I have the exact same model but can't seem to find the right plungers for thr injection pump Thanks a lot

[@ciscothecisco2792]

Hi there great videos you’re definitely the best…i’m trying to do a timing on my 753 but when I turn the engine I only get fuel from two and three nothing comes out of 1 and 4…does that mean I need to replace the injector pump? Thanks

[@tetradgroup]

Did you turn engine over several times? Maybe used to start her and turn the engine over to see if any fuel comes out of one and four. They're on an opposite stroke than 2 and 3

[@shawnc5728]

Great video, thanks for your efforts. I have a 773F (V2203) with BOSS. I had the engine out and replaced all the gaskets and seals. I also pulled the engine harness and repaired several cut and burned wires and removed a pair of wires that were ran from the harness to the ignition switch, which appeared to be installed to jump damaged wires. Now when I turn on the ignition, the fuel shutoff and glow plugs are not getting voltage. I do not have any coolant in it, the brake is not plugged in, and the the steer handles are not installed, would any of these conditions prevent voltage from getting to the fuel shutoff or glow plugs? Do you have any thoughts on what is going on? Problem with the BOSS Module? Any guidance is greatly appreciated.

[@Redneck_Engineer]

I just rebuilt a stuck kubota injection pump. I'm wondering if you put any oil or assembly lube on the roller tappets or cam, or anywhere else on the pump for that matter, during assembly?

[@tetradgroup]

I just use a little engine oil for installation because it's a roller assembly.

[@johndoshier6825]

I've got a 1997 751 bobcat with a a Peugeot diesel that starts weak after cranking a lot . It only idles and if you move the throttle it doesn't speed up the engine and usually dies . Put a new pick up tube in a few years ago and primed the filter and to the injector pump as well as put in a electric fuel pump which really didn't help much . It idles pretty smooth once it starts wherever the throttle is set and if you raise the boom or move, it usually dies . Acts like it's not getting enough fuel but the electric pump is putting a lot of fuel to the injector pump . Any suggestions on the Peugeot engine ???

[@Jamestreeman]

These videos are awesome

[@johndeere0930]

Would this pump cause low power under load? Especially with in spec (adequate) fuel flow and new injectors? Any help I appreciate much thank you

[@tetradgroup]

I could but have you replaced the lift pump yet?

[@johndeere0930]

@@tetradgroup yes sir! New lift pump 5-7psi new pickup in tank with check ball Idles up slow when taken to full throttle then if you turn fast or scoop into a pile of dirt it just falls on its face and if you wait RPMS will come back up

[@johndeere0930]

Throttle not very responsive. At idle then right to WOT it’s like it’s sluggish to get up to “speed”. Thank you for helping and responding!

[@michaeltoner2794]

I have a MT 52 walk behind bobcat. It pours black smoke out on starting. Once it warms up it calms down a little bit. Would you say this is a injector or injector pump ? Or is it getting too much fuel and is there an adjustment for that. I enjoy your videos.

[@elirivera3223]

Oh man he hasn't replied as of yet??? Mine smokes all the time but does calm down after a while. Hoping he replies soon.

[@stumper798]

does the valve on the injustion returne line have to be open or close when the engin is running, or what is the purpose of it.

[@tetradgroup]

Closed when running, it's a bleeder valve

[@benvarguzisier3181]

My kubota svl75 stayed on full throttle. Is this a big issue to remove the fuel injection pump? Thanks

[@sprintcarracer77]

[@andrewblessing9969]

I have a 763H that seems to bog the engine down when moving the machine. Seems to run the implements ok. I changed the fuel filter and hydraulic filter and it was a tiny bit better. Could the injection pump be the issue?

[@tetradgroup]

Could be but probably a fuel delivery issue to engine. Have you checked lift pump?

[@victorhernandez769]

Thank you for the video gracias...

[@Jason11885]

I just rebuilt and trying to install fuel injector pump and when I get the bolt almost tightened down the shut off slide won’t move anymore feels like it’s hitting the pump have you ever had a problem like this

[@tetradgroup]

Did you line up the rack pin to the notch in the governor linkage?

[@Jason11885]

Yes it slides until the bolts are almost tight I took the side but off that has the spring and checked to make sure it was sliding

[@ElmigranteNews]

Hola donde puedo encontrar esas bombas ?

[@drkbltn]

Any input as to why the motor would runaway after installing a rebuilt injector pump?

[@tetradgroup]

Rack pin might be in front of governor linkage. Pin has to be in linkage slot. Remove stop lever plate and inspect rack position.

[@drkbltn]

@@tetradgroup I figured it out, the governor was just stuck wide open for some reason. When I released the linkage and manually idled it down it was fine.

[@colebrown9522]

The 743’s and 742’s have the Kubota 1702. Do they have the same pump as the 2203?

[@tetradgroup]

Identical pump and same process for the V1702

[@Modernexodus1]

Is this basically the same process on a Kubota 2003TE engine? It is in my 341 Excavator. The pump is leaking at the base. The pump seems to be working fine, but the seal at the base is leaking. Can I re-seal it?

[@tetradgroup]

Same process for the 2003.

[@Modernexodus1]

@@tetradgroup Thanks for the quick reply. The pump is leaking fairly bad but the machine is running great. Can I keep running it?

[@tetradgroup]

@@Modernexodus1 you can run it until you have time to fix it. My injection shop usually takes 2-3 days but lately it's been taking over a month due to parts shortages. Depending on wear and or damage a rebuild cost me anywhere between $500 - $700. You can probably find a reman around the same price to help minimize down time.

[@leroycastensjr.1930]

I have a 763 and the engine starts fine,low idle is fine but my high idle will only go to 1400rpm. I checked the throttle linkage and the fuel stop linkage. Could I have a governor issue?

[@tetradgroup]

Possible, I'd check the governor springs to pump control. It's a spring inside a spring and if one is damage you will not get full throttle. Remove the stop lever plate and you should be able to see where spring attaches.

[@103regan6]

Mate got 753 if iv taken them 2 shims out so now it’s got none will that stop it from starting up I took em out to advance timing would not start. Then replaced head gasket still won’t start

[@tetradgroup]

It should still start without the shims. Are you sure the lift pump is working and you have fuel pressure to the injection pump? Fuel solenoid is pulling open? Try a small shot of ether or brake clean into the intake and see if it tries to start, could be a mechanical failure. Also remove hydraulic drive belt to make sure it's not a parasitic load on engine. Have you checked compression?

[@juansoule8032]

Hello I have problems that the Kubota V2203 engine in hot state does not start, what problem had my pump?

[@tetradgroup]

Lots of possibilities, is the fuel pull solenoid opening when you try to start? Next would be a compression check. Try to start with a tiny shot of ether, if it starts you may have low compression. Also check lift pump, open bleeder on fuel filter housing and try to start engine and see if fuel flows from bleeder screw.

[@Juan-bw3jp]

@@tetradgroup It has the engine with good compression and the low pressure fuel pump just replaced.
