TESTING A DIESEL INJECTOR NOZZLE 

Welcome Stitches and Camera Lady! Nice seeing the new additions to the crew :) Keep up your good work.

Nice test setup...it's always amazing to see a bad injector verses a good one.

your a very clever bloke, interesting and informative, glad I found you on the tube.

Nicely done, couldn't have come at a better time for me. Tomorrow I will be checking my latest acquisition over, a 1950's Kubota diesel, my first diesel stationary engine.

That's freaking cool to see the injector in action. Thanks for sharing

This video helped me a lot !!!!!! I could not get my new injectors to work, also bought a new injector pump also, $$$, I bleed them a lot .but none of the kubota repair books I purchased had the simple adjustment on the top of the injector you showed in this video , I did this and tractor starts right up , and runs smooth , thanks I love working on different projects that I know nothing about and youtube is so helpful

Acquiring Buda is how Allis-Chalmers got into the diesel engine business.

my old boss had a fancy diesel injector tester,he showed me how to use it and NEVER put any body part near the nozzle when testing. same goes when cracking a injector line when bleeding air or diagnosing a driveability issue ,2 -3000 psi will blow a hole in your skin and cause blood poisoning which could lead to death

Cool demo on how an injector works ..The tester is a nice tool to have

This is good stuff, I’m a Master Mechanical Tech. and I love learning new stuff. Thank you.

Nice set up. Thanks for showing us that

Very cool Mike . Keep up the good work It was nice to meet you and RK at jack town a few weeks ago

Loved the way your girlfriend drifted the video to stitches near the end while you were still doing your piece to camera and I'm sure she really was interested in the nozzle test.......😄😁...! Don't forget the CAT updates👍

Good video! Dribbling injectors cause smoky exhaust and if extreme will wash lubricating oil from the cylinder walls. Often it's caused by worn surfaces in the valve or bad o-rings. Sometimes lapping the valve disc and seat will restore sharp cutoff. But, for a show engine, it's not really too critical.

Lol Good stuff Mike. She's a keeper. cheers.

Interesting video for sure. Thanks for posting!

Good just like I was taught in diesel systems class. I don't know if you did this we used to polish the injector pin and point with very fine (not sure I spelled this right) rouge and a felt pad. I think you can very carefully relap the pin and seat with the rouge just make sure you get it cleaned up good. Its been 20 years since those classes. Good luck.

Owe my god when the video hit 2:40 time, My misses made that sound in bed, Does this mean her pressure builds up gets to 1700 psi before she releases. Got to be separate beds for me and her from now on` she may blow a hole in my skin lol Great Video but safety glasses and masks you do not want to be breathing in all that fine mist to often all else your be sounding like that when you breath. You should also catch all fuel with measuring bottles to measure each jet, to see if they deliver all same level fuel

Excellent video

Interesting share Mike , That should work as a show piece . Sure is good to have a camera girl , My wife & daughters are handy for that . Good looking dog to man !! Thumbs up..

This is a very good video,thanks,i have one cyl. knocking from the injector, (Iveco DI 8140.21 2445 cc on a 1987 Sea Ray Seville CC ,here in Porto , Pt )have to remove it,too bad i still don't have a setup to pressurise it; i shd have made one like yours long time ago lol

I converted a porta power pump. Had to make my own adapters, but works well.

That's a neat tool!

Good video and good Camera work!

Neat Gadget Mike .

Thanks for the vid mike. On your caterpillar genset, I would like to see those nozzles

Good job Mike canned that also be used with fuel gas fuel injectors ! 😎👍

I have three diesel engines (one even runs!) but I have to profess ignorance. What would be the disadvantage of a higher cracking pressure? Too hard on the pump I guess? Mine all have unit injectors driven by rockers. Not sure what the test procedure is for those.

cool demo.

Well explained. Good setup. You should teach.

How do u find time for a missus

That's right, don't tell her how to do her job ;) Great video.

Can you lap the parts in so you can either reduce or stop the leak

Can you test bosch injectors on this. The ones with cable attached?

GOOD JOBS MAN

My uncle have injector tester inside him he make the same sound.

Can it be sent out for repair?

No one is mentioning how to prime the tester, I think i have bought a dud? any one link me to a pop tester priming video?

Cute pup, there a story behind the name Stitches? Nice camera work by the lady and concise mini-lesson on injector-testing, fascinating stuff, thanks Mike!

good Camerawoman!!

What injector was that?

hi mate, wondering if you could help me. I've got a turbo diesel, all mechanical. the turbo isnt making more than 4psi of boost, it should be 11 psi. i know the turbo is okay, and theres no leaks etc. I know its down to the fueling - so my question is, would a dodgy injector cause almost no boost but still get aload of black smoke? Im at the point where i know i neeed to check the timing and then injectors, just wondering if you think it'd be an injector too ? I know its fuel, just not sure on it being an injector or timing. Im almost certain its not the bosch ve injector pump at fault. as far as turbo/actuator/boost leaks and hot side leaks, everything is fine, which is why i know its down to fuel, just trying to get others opinions on injectors failure causing black smoke but no real boost? Cheers mate

Sure wish I had one of those nozzle testers.

Camera lady has attitude

yup she a keeper like.

2:37 A-10? :D

Hey, Stitches.

I don't believe you have a big problem, you obviously was pushing the handle down much slower than the injector pump will be building the pressure. I have helped test injectors, but don't remember ever trying to build up to cracking pressure like you did. We were looking at how the injector spray appeared. I was a welder who helped the mechanics when they needed a hand, so this is only my opinion, not from an experienced diesel mechanic.

I'm watching this with a weird Buda generator and Bosch injectors like these.....

It farts a lot

Fffttt. It wasn't me...

You might want to invest in a fluid filled gauge it would dampen the stutter.

Stupid gas lamp! You hung it too low!
