Pop testing and DIY reconditioning diesel injectors

[@andreyzagoruyko5390]

Stopped all my injectors from leaking; God bless you abundantly!

[@Big.C]

Cheers buddy was looking for a quick explanation on testing with this tool This fits the job 🤙

[@59silvereagle]

Awesomeness, thanks man very informative for a diesel injector ! 👍😉

[@suburbanrapper]

may you live a hundred years... god bless you for your help

[@colinaglae9753]

Thank you, Sebastian. It was a very informative video !!

[@Sounddoctorofficial]

Aside from the knowledge...Ur very funny/entertaining mate. Earned yourself a subscriber

[@TheRealKlinky]

Love the Bahco adjustable spanner...best ever made👍

[@sam40901]

Cheap electromagnetic injector stimulator is a step-down transformer 12v ac 5 amp with one rectifier. It's called half wave . Will give 30 cps pulse output. It works.

[@tonyschmood8587]

Awsome video dude much likey!!

[@ingergriggs4626]

Like your video. Never thought of lapping the inside of the tip. Never tried it but I heard that you can use tooth paste for tip cleaning also.

[@calvinkalmon6746]

Your funny as shit! Really appreciate the info.

[@fixingstuff8117]

Thanks, great info on crappy video. Not that I am much better. I tried toothpaste few years ago, will try some polishing stuff. I want to increase my injector pressure also a little. And want to gey some chatter if possible. Thanks.

[@JoeNunes345]

Great info, especially on the lapping of the tip. Do you think that type of injector can be set to 250 bars? Many thanks, Joe.

[@findvoltage]

hope you had a boot on the other foot at least or was they matching green socks?

[@alexpanzer632]

What is the right pressure untill the nozzle starts to sprayng?

[@enquire422]

'Mer' as an injector cleaner. You learn something new everyday on KZbin! Some good quality nitrile gloves would do wonders in protecting your hands from future misery.

[@DaveCovert]

I learned that Brits call lamps 'torches' (already knew that) and blow torches 'blow lamps'.

[@ryancamilleri9473]

Thank you for all the info btw is this good for bmc 1500 engine? Tks ryan from sunny malta

[@hamish2202]

Helpful thanks

[@anthonyheredero9823]

Dude, how much pressure is the opening pressure of that kind of injector?

[@FiglioBastardo]

Great video! I think you should do a new version of this with a higher resolution camera. You did this subject great justice for sure!

[@loveyourself1759]

just get an ultrasonic cleaner I recommend the mineral detergent from emag, got my injectors nice and clean, all the holes are free now, checked it with a flashlight put em in storage tho cuz I installed larger nozzles for some more horses :D

[@MrTsonkov]

Hi Sebastian, nice and so helpful video. But what if we have electric injectors? do I need to connect to the battery? Can you explain, please? Thank you

[@johncollins8304]

I can afford new nozzle(s), 'cos I only need one on a monocylinder Hatz E75 (on an ancient dumper), rope start. But I would like to know more on how they work. And specifically why a new nozzle I left lying around for a couple of years but have a sonic bath failed a test at the garage. I'm yet to find a close-up of the end of the pintle showing the holes. Someone here said he can test that they're clear by using a torch. I don't get it. I've got some wire-drills from 0.1mm up. I imagine the holes are much smaller than that. Thanks for great vido.

[@commercialfishingnet2188]

Remember that it's not a toy, must have protective clothing and gloves you could get gangrene, that's a lot of pressure

[@napper1496]

Know a guy who has lost his thumb thru putting it over the end of an injector

[@housedaz]

Hey great video.. can u tell me how you prime the pump please. Im geting no pressure from mine

[@1768ify]

I tilted mine forward and kept pumping. Took a while. Some of them have bleed screws.

[@howtocreatesculptures6713]

Nice video i learned a lot : ), can you tell me what adding shims to injectors does ? Does it make the fuel flow easier or what ? Thanks and have a nice day.

[@ww07ff]

It increases the load on spring, increasing the injector pop pressure.

[@howtocreatesculptures6713]

@@ww07ff thank you ! : )

[@myharris]

How do you set the black thumbwheel on the right of the tester? I have one of these which came without instructions and I can't figure it. If you tighten the thumbwheel up, you can't move the handle at all. If you slacken it off you can, but where are you sposed to slacken it off to? Is there a technique for this? cheers for your help

[@1768ify]

It seems that you can open the wheel a few turns, and then use it to add small bits of pressure by turning it closed.

[@myharris]

@1768ify Thanks 👍

[@godwindavid3646]

Can this cause high diesel consumption?

[@TheSubpremeState]

Can you test injectors with the cable on the end on these pop testers? Bosch piezo etc.

[@plumbteam]

Sadly not

[@TheSubpremeState]

Sebastian Hibbert Damn. Is there some kind of voltage regulator thing that you can use along side this pop tester? Probably too expensive.

[@TheSubpremeState]

I found this in the mean time. Theres a decent looking one for around $230 also. m.ebay.com/itm/CR508-Diesel-Common-Rail-Pressure-Tester-and-Simulator-For-Bosch-Denso-Tool-VBQ-/253414351948

[@plumbteam]

It’s not just electrically - common rail injectors are running at 1700 bar not the 250 pop testers produce

[@TheSubpremeState]

Sebastian Hibbert ah right. Shouldn't be too hard rig one up from a fuel pump and higher pressure gauge. Maybe

[@napper1496]

Why faff about with needles when you can just buy new nozzles. They’re not as expensive as you would think like 5 or 10yrs ago. Even new nozzles need set up though. But a tip to others….don’t buy one of these testers. If you don’t want holes burned in your pistons etc do yourselves a huge favour and go hand your injectors into a diesel specialist and get them to source nozzles and pop test and set them up professionally. There’s a lot more to it than just opening pressure. Most specialists will charge £20-25 per injector to set up. Well worth it trust me. I always take mines to diesel place in Cowdenbeath Scotland. Davie has 40 yrs experience and has the Bosch tester machine etc.

[@austinharrelle]

Torch tip cleaner and ultrasonic cleaner.....,..

[@Urmza]

What is that Mer stuff? No clue so far

[@chillstar]

The word POLISH on the front of the bottle is your clue.

[@kittukittu3665]

Lap your old injecter with FINE past, clean it and fit in your machine

[@johncollins8304]

£40 off ebay? Maybe when you made the vido but now 100! To test and regulate (??) an injector, a shop wants 30€. You've said elsewhere you've not bothered messing about with shims when you've changed a nozzle. I've never even handled an injector, nozzle, pintle until recently, on an ancient monocylinder Hatz E75 on a dumper. But thinking about it, my tractor is diesel, my digger is diesel... Hmmm. Trouble with eBay is that there are no reviews, unlike Amazon.

[@darn7451]

Some of your tips are good, some of your tips are bad. Pun intended.

[@macindoe]

Hi Sebastian. Here are is how my testing went. kzbin.info/www/bejne/nXmqZ5R3as-ffLs What do you think? Injector 2 looks pretty leaky. Is it worth trying to fix? Also, would the next step be to test it with my fuel pump? I'm guessing that would now give me a fairly good indication of whether my fuel pump is working or not?
