Great video, but what would be the symptoms of a drained amplifier module? My car had a faulty return pipe and now the car wont pass the emissions test. I am wondering if it could be due to a drained amplifier module, which causes an injector to stay open. Is this palausible?
I did some further research, and found the answer to my question. It seems that a drained hydraulic coupler or amplifier will cause the injector not to inject.

Hi, regarding inside the nozzle theres a small spacer then a spring and another spacer which is bigger and also has a flat surface on one end and tapered the other end, which way round does this go please? Many thanks
Thank you, very informative video! I have a bmw with rebuilt injectors that keeps blowing the plastic non return valve on the return pipe. The report shows that the injectors are in good condition. What can be the problem?
I am very sorry but we cannot advise in this case. We specialize in the production of spare parts for injectors, and we have some experience of injector repairing ourselves, but we never work with engines as a whole thereofre we do not know what may be causing your issue.
Hello and thank you for this video. The mentioned draining of the amplifier module, can that happen only when disassembling the injector or also while performing a classic return quantity test? As far as i know, these tests dont use any non return valves..?!
It usually drains during the disassembling of the injector. During testing and operation on the vehicle the injector is connected to a backleak pipe wih a non return valve, the non return valve prevents the amplifier from draining.
It may not be sufficient to replace the valve. Generally, the nozzle should also be replaced, then there are all the other components, to check and replace as needed. In piezo injector, great care is also necessary when refilling the amplifier piston. Many different factors all concur to the final outcome.
The spraying pattern depends on the nozzle and it is fixed. If you use the correct nozzle, corresponding to the injector part number you are servicing, it will have the correct spray pattern.
Hi... sir good morning.. sir we have Bosch EPS 815 Test bench... how to test continental injector and continental pump (Delphi) on this bench ...or how to test on Normal Mico Test bench..if any specific toll we need where we will get sir .. please send me any suggestions sir...we have also Mico Test bench sir... please help me... the you sir 🙏
I am sorry but we do not know the part number 30750283 so we cannot advise about it specifically. The nozzle nut of other Bosch Piezo injectors is tightened at 56 Nm.
No, we do not release test plans. Every workshop should source a brand new injector sample, thest it on their own test bench and conditions, and take note of the results, possibly keeping the "master" injector as a reference for later comparisons. This is the only way to assure that the results are consistent and comparable to later tests made on the same equipment and conditions.
The fuel delivery of the injector can be adjusted changing the size of the spring shim, our kit 1 214 535. Please contact sales@redat.com if interested in an offer.
We specialize in the production of spare parts and tools, but we can offer rebuilding as a service depending on the type of injectors. Please contact us at sales@redat.com indicating all the details of tyour company and of the injectors needed, and we will advise.

Great video, but why after assembly piezo 115 injector nozle cap/nut it leaks on the thread? I have marked nozzle cap and it is 50lbs torque but after tightening to same mark it leaks, I noticed there is a thread lock/seal on injector body, do I need to use another adhesive/sealant?
Hello, the tightening torque for Bosch Piezo nozzle nuts is 56 Nm. We confirm that there is a seal that goes in there too, our reference 1 211 385. If you want to try and replace it, please contact our offices at sales@redat.com, and request an offer, it is in stock.

Hi, regarding inside the nozzle theres a small spacer then a spring and another spacer which is bigger and also has a flat surface on one end and tapered the other end, which way round does this go please? Many thanks
Hello! the flat side goes towards the nozzle tip, tapered side towards the injector body.

Hi. that small washer on 4:03 has on side flat another not, which side he put up?
Hello, flat side up towards the nozzle.

Hello and thank you for this video. The mentioned draining of the amplifier module, can that happen only when disassembling the injector or also while performing a classic return quantity test? As far as i know, these tests dont use any non return valves..?!
the non return valve is necessary also during testing, otherwise the amplifier will empty.
@@RedatSpAVideo ok thanks
Very nice video
Can you explain why the amplifier may drain? Also does that apply only to test bench or fitting in a car right away it will drain as well?
It usually drains during the disassembling of the injector. During testing and operation on the vehicle the injector is connected to a backleak pipe wih a non return valve, the non return valve prevents the amplifier from draining.
@@RedatSpAVideo ok understand, the high pressure pump have non return valve within it?
Great job. Are there any special precausions during instalation piezo injectors into the engine?
I am sorry but we focus on injectors and their internal components only, for the installation on the engine we cannot make suggestions.

Is iso oil a hydraulic oil?
The full definition is ISO 4113, it is a standard for oils to be used in calibration instruments, such as the common rail test bench in our case.
@@RedatSpAVideo Can I inject ISO 4113 alternative diesel fuel?
@@jejumsautocareaxis8470 No, you cannot use diesel fuel instead of the ISO oil, it is not the same.
I like to cook my eggs in the morning with iso 4113 oil.

hi can you explain why injector ot spray fuel? i open injector to clean nozzle and i put back everything how i found but injector is not spray fuel
It may be the amplifier, that needs to be recharged as we show in the video.
