How a Diesel Injector Pump works CAV DPA Build Part 1

- เผยแพร่เมื่อ 17 มิ.ย. 2017
- Rebuilding a diesel injection pump can be intimidating, but these CAV DPA rotary injection pumps are very doable with a good kit and some good video instruction. This is Part 1. It's about like playing with a fidget spinner once you know what to expect.

Briansmobile1 you must be a diesel tech of some sort and if you've got a second, I've got a question about these CAV pumps.
My old Long 350 is getting diesel at both fuel filters and when I get to the injectors, it isn't squirting out quite like the low pressure side of the pump.
My CAV pump has bleeders on both the low side as well as the high side and they squirt diesel good; however, when it comes to the injectors... It's a pathetic trickle of diesel and not spraying out into the air as it should be.
Bled filter #1
Bled filter #2
Bled CAV low side
Bled CAV high side
Bled injectors and it never amounts to much of anything spectacular, weak run-out.
Would you assumed that my CAV injector pump could have gone bad and if so what area would I be looking to rebuild? That's assuming I can find the parts for it, but I need a second head on this one... She's not a spring chicken, but it's spring and I've got to break ground, about 2 weeks ago.
I cannot seem get a constant start, just one hit starts and instantly dies out... I appreciate your videos!
Thank you sir.

Even if I can't use the information about the item your explaining, I come here for the enjoyable editing! Your videos are easy to watch and I end up learning something anyway.
You never know what information is going to come in handy. You could find this info useful when working on a sailboat, London Taxi cab, or any number of tractors.
interesting, enjoyed
good job man
Good work
Magnífico video! Bravo!!!
Una pregunta: la bomba del video se diferencia en algo con las bombas CAV que usan los viejos land rover series??
make sure you take apart on dirty work bench and floor. Then put together with cigarette ashes in it.
Then send to me to rebuild .
Must be clean clean work area!
I see you know that. Excellent work thanks!
I like! Keep it up!
Thanks!
Hey, wow. great information!! I've driven CAV pumps over the years in the old days. I've wanted to know how the inner workings of the pump! I have many questions to ask, but don't know where to start lol. I'll start with one, how is the governor is powered by? spring, amount of fuel?
Video excelente, gostaria de um video instalando Bomba Delphi 210 na bancada para teste pricipalmente a intalação do medidor de avanço, medição de pressão, solenoite etc.
Great video. This pump seems really complicated. Hope next videos will focus more on the subject.
I've got piles and piles of footage. What would you like to know about? I'd love some input and questions. I've got information overload.
I need info on the flyweight retainer replacement deal. Older versions from 60s used a vinyl container which can come apart in pieces and that might lead to loss of throttle control if 'not idling down'' symptoms are ignored to the point of way past stupid. Replacement retainer is metal and doesn't come apart, so we should really get in there and replace it while replacing leaking throttle shaft seal which just spills the top half of the fuel tank until that o-ring gets renewed from inside.
hey thanks for sharing. i wpou;ld like to know more on the inlet. is there a spare parts list? what is the assembly sequence?
great video, have a question, if i lost my governor spring settings and have no markings that id them where do i start? I took an educated guess and it does crank and run but does not fell like full throttle and it will shut off at half throttle with the fuel advance lever not using the shut off pull. which way to go? or change to set spring right?
brian pleSE PLEASE PRETTY PLEASE WOULD YOU DO A REBUILD ON A BOSCH VE TYPE PUMP as a little sideline project maybe - I am in the uk - been an avid watcher for years, keep up the good work - you are far more meticulous than I am - commendable dude!
If I get the chance I will. I don't have one here at the moment.
Man you do a great job describing things and great editing too...i really need your help,im gathering info on rebuilding a dc style roosa master which if i understand correctly the cav was designed after, could you please help? Its a little more complicated cuz it has 4 rollers and pistons...
I️ am trying to find the fuel regulator. Where did you get it ?
I have similar pump but I'm getting tremendous pressure returning back to fuel tank that it blows fuel out the breather hole in the tank cap or it blows apart the return lines from on top of the intectors
Brian, how difficult is it to start these Pumps once they have been reassembled?
Should they be spun with a drill etc before putting on the engine.
Is it possible for this to get blocked and shut off fuel flow, I am thinking this is what has happened to mine since I can't get her to run due to no fuel coming out and up to my injectors?
The diagram at 4:45 of this video shows the "roller shoe ear" placed upside down from how you installed them in part 2 at 0:39. Which is correct? Maybe it makes no difference?
the vane pump nut that holds the vanes has come loose what torue do you tighen it to
That intro was actually kinda impressive, hw many tries ? :D
I did it off camera first try and like it, but it was slower. On camera it was 5th or 6th try going faster.
Good morning dear I have a tractor mf 165 engine Perkins 4.203 The diesel pump was damaged There is a part of it (cam ring) I want to replace it and I do not know the code. Can you write me the original number. I live in a war zone where there is no service
Parked my mf 165 for years and would not fire up now. Lots of fuel. The pump is just not putting out. Stuck fuel cut off ?
How does that fit in the back I'm confused
I need help finding information on adjusting main fuel on a pump lile this one but the pump seems to be pretty rare it's on a perkins 6.354 can you help?
That's one of the Perkins 6 cylinders right? There are manuals you can download all over the internet for the 4 cylinders. Are you talking about the max fuel setting on the rotor?
Yes max fueling I'm trying to get some more power out of it and I've found a few videos on the same but with different pumps I'm having a hard time finding this one ...are most rotary pump similar? I just need a general idea of how to do it
The fidget spinners got you too Brian???
I've got kids right?
I really wish you had not time-lapsed the regulator assembly - I need to see that in detail ...
Exactly wat i needed
@@wadeadams2775 That's what I mean; using those words makes it political.
My Cav is similar (JD5300) with the shutoff solenoid instead of the internal kill valve. I can not get mine to prime. when I try to prime it the manual lifter pump works for a bit and then gets too much resistance. I took out the solenoid and fuel gushed out from that place. I was able to remove the plunger shaft from inside the solenoid and reinstall it but still can not pump it to prime. I am wondering if you had any suggestions- thanks
Is it possible that this IP has a backflow valve at the return outlet? at the arrow in this screenshot : www.screencast.com/t/xB0TnHDJKJH
Hans Rose is the metering valve stuck or did you check to see if the solenoid was actually working?
You hear folks go on about Diesels being so much simpler on account of no ignition systems. Ever notice how those same folks never acknowledge the existence of injection pumps? Diesels always have me thinking 'stinky Rube Goldberg[1] device'. (Unless one's a run away, then I'm thinking stinky dangerous/treacherous Rube Goldberg device...)
[1] For those under 60, see Wikipedia.
The injection pump here is super simple except for the anti-run away parts of it.
