Let's find out if we can build a DIY diesel fuel injector pop tester! We need to pressure test our Yanmar tractor diesel injectors to make sure they open at the proper pressure. This is the best way to tune a diesel engine. If your diesel tractor is running bad this will help! PARTS BELOW ↓↓↓↓

● Pipe: amzn.to/3IC8E15
● 3/4" Reducer Bushing: amzn.to/3D9s4ZP (I'd find a bigger one to screw in)
***All of the pipe fittings have to be hydraulic pressure rated. DON'T USE CAST PIPE FITTINGS. THEY WILL BURST!***
***High pressure diesel is DANGEROUS and can HURT you! Be careful and keep your eyes and hands away from the fittings and injector nozzle when performing these tests!***
These injectors open at 2275 PSI or 160 BAR.
This is a Yanmar YM2000B Diesel Tractor.

I rebuild diesel injectors pretty much 24/7 and Ive got to say that without a doubt Yanmar bodies are the hardest to hold while lapping the sealing faces. One thing to be careful of with the Yanmar injectors is the thickness of the copper washers that go on each side of the return rail. Too thin and it allows the bolt to go down onto the adjusting shims bootin the injector pressure thru the roof in some cases. I machine an amount of rach bolt if they come with the injectors and always inform the installer to use thicker Dowty type washers or thick copper ones.

Thanks for the info. I will keep that in mind for the next Yanmar engine I work on. I see exactly what you're saying. That would throw off the PSI big time.

Just to be clear are you adding diesel through the fill port in the back? Thanks

@MattsShop 6 ай бұрын

Yes. I top off the jack cylinder with diesel through the fill hole in the back.

How much fuel should come out of the fuel lines before the injectors? I can get fuel to come out injectors. I have already made sure the needle valve moves freely

You mean to tapp in the adapter which you welded in 2:16? Thanks

@MattsShop 2 жыл бұрын

I would tap the top of the jack and not weld anything. The part with the nut on it that screws into the top of the bottle jack.

I need to make some shims. I'm in Hungary.. No idea where I can buy them but I can hire a machinist to make them. Do they need to be made of some certain type of metal?

@MrRacerhacker 3 ай бұрын

not really, get some steel washers, can also use steel shims from gauges, can do it also with a small piece of plate steel as well just sand it down
