How to test, remove and replace a fuel injector for a Yanmar type single cylinder diesel motor / generator such as the Aurora Diesel Generators from EmergencyPower.com
Very helpfull and intuative video and great quality too. One thing though, please, please don't use those nasty "grip things" like at 0:04, get some propper spanner and not only will you find working on it easier but you won't round off all the nuts and bolts. Otherwise, great video and thanks for sharing it with us.
Important safety tip. DO NOT put your hand over the injector while you're firing it. It WILL shoot fuel through your skin, and you do not want that. That is a horribly painful and disasterous condition.
Yea holly crap I was furious to see they are teaching people to check without talking about safety. He already removed the high pressure line could have easily relocated it inside a bucket or something by removing the return line. That's what I did on mine.
If I saw someone using multi grips on the injection line nuts instead of a 17mm spanner, or at least a shifting spanner, I’d give them a back-hander in the mouth and tell them to go buy some tools and learn how to use them.
I cringe just using a shifter on some parts of my diesels. Couldn't imagine using that thing. Better grips (self gripping things that were advertised on TV) I could just tolerate maybe 😂
Spanners are better than toothed pliers for nuts. Marked nuts do not look so nice and resale value drops fast. If he undid the nut on the pump and the nit on the injector, there would be no need to bend high pressure pipes.
Thank You for the public service of making this video. I've subscribed. However, I have to say, I'm cringing every time I see you use those channel locks.
Thank you for this super simple lesson. It is made to a deisel Ignoramoose can figure it out.... I am a deisel ignoramoose.... I can't even spell deisel right....
Dear i have one question for you.....i have seen people modify a bottel jack for testing a desel fuel injector. Can we use this generator desel fuel pump to test the pop pressure of any desiel injector ?
I have one of these engines in my generator. I bought it new but it has been sitting in its box for over 3 years but won't run. The fuel pressure from the pump is very weak and sprays nothing like yours did. I took out the pump but it looks clean and the spring pushes in and out OK. Is that a problem leaving it for so long do you know? There is a strong flow of fuel to the pump's inlet and no air locks and the battery is new. Anyone have any ideas?
Hi I have a generator with a very similar engine to this one trouble I'm having is it is piping out of the intake when trying to start if you have any ideas what it could be thanks
Mas sy pendatang baru nih masih kurang paham kenapa kalu di setarter kok ngg bunyi kaya yg di vido ini melain kan grutuk deg gitu ms apa peyebabny makasih sebelum ganti oli di star ok setelah gati kok susah setar sy pake oli B40 apah salah oli mohon suhuu keteranganya
Mine is running for about 5 sec then cutting off , I have bled top and bottom and have good oil ? Could it be my injector , less then an hour of run time it's new . I have been running once a month for 15 minutes, puzzled?
Buenas tardes patrón una preguntita inyectores para esos motores generadores de diesel dónde los puedo conseguir si es tan amable de decirme lo que pasa que tengo malo el inyector y no este no lo puedo conseguir la verdad yo soy de aquí de Tejupilco Estado de México
Dear youtube, i have a similar engine (winsun type 192) as new but does not give proper output; Injection timing is okay, pump arm moves all the way to the right, but no smoke and bad cold start. I cannot find anything what causes the defect. Anyone an idea?
The very first thing we see is you putting channel locks on a plated bolt. Come on, Grade 7 shop students know better than that. Look at what it's doing to the bolts, they're already all chewed up. Awful; a how-NOT-to video.
What the hell kind of mickey mouse mechanic are you? Never, ever bend the high pressure fuel pipe, ever. You will weaken it and it could split at a later time. Don't be so lazy - undo both ends of the pipe and remove it. And get some proper tools for god sake, even for the sake of the video. Using pliers and locking pliers damages the fittings and is pure laziness. I sure hope you never get near any of my engines! Amatuer.
