This is amazing. After graduating from pakistani rebuilding videos, to an english annotated rebuilding video, and then a cutaway demonstration video, i see this and now i finally know how the leaking pump in my van works. Baby steps, baby
Leave the full load adjustment screw alone !!!!! Hmmmm.... I would want to, but I'm so tempted of power on one hand and extreme fuel economy on the other hand. Thanks for the video, it explains a lot.
It doesn't increase power just makes alot of smoke. Over fuel does not increase power unless more air is also pushed into combustion chamber with extra fuel . New CAT Cummins no smoke 600+ Hp dual stage variable geometry turbo push huge amounts of air into engine with more fuel to make more power. Not just extra fuel dumped in.
@@Nudnik1 fuel makes power, not air.. air cools the charge and makes it burn clean. unless you increase fuel, a different turbo isn't going to make any more power in a diesel. Yeah, what's the displacement of those new Cat Cummins? My 5.9L 12V makes more power than that so it's not exactly impressive. Also, increasing the full load screw setting doesn't really affect fuel mileage unless you're always using that additional fuel, at cruising speeds, your fuel delivery is set by the governor
Bjr moi g démonté pour la deuxième fois ma pompe pour vérifier que j'avais bien tout remis comme il faut mais cependant à la clé la pompe tourne d'un cran d'un côté et d'un cran de l'autre et même en forçant sur la clé on peut pas faire deux cran est ce normal je suis pas sur si tu pourrais me montrer en vidéo en tournant l'axe de ta pompe à la clé merci
Hi, great videos I'm learning a lot. I have a ZEXEL VE pump but need it to operate in the opposite direction. Whats parts do I need to change to achieve this? Thanks
Yes they are good videos. However, does anyone have the data sheets to set these ve pumps up...or is there a link....l cannot find one. I need help, l have rebuilt mine and need to double check the gaps etc.. But not having much luck Also the timing should be taken from the pumps TDC ie max movement of the plunger...that is clear and not BDC....this can be a bit misleading...but the video shows TDC...and then you work backwards. However, l may be wrong. Maybe l could be corrected. Thanks
From what I can tell, those are closely guarded trade secrets that the certified shops do not want out in the public. They want you to need them to calibrate it for you. I just sent my pump to the Bosch diesel expert in North America to be upgraded and rebuilt. I was going to try resealing it myself but saw how much there is to calibrate them correctly. After seeing what options I had, sending it in was the best option. Although it is not the cheapest option in the short term, it is in the long run.
@@davidparker9676 When I resealed mine years ago I just measured with a dial caliper and recorded everything and put it back exactly as it was. Purrs like a kitten.
@@1320fastback My pump developed a vacuum leak on the driveshaft bad enough to prevent it from running anymore. The main driveshaft and bushing were worn so badly they had to be replaced. Sending it in for the rebuild was the best option for me. I had the pump upgraded and converted into a turbo pump along with the injectors. When I get a little free time, I'll install the turbo components. I'm looking forward to the extra boost in power the turbo will add.
garbage ,,, common rail was the death of everything a diesel engine was , and all the things that made it great ,,, then came emissions , since they have tightened the emission standards engine life has gone down hill rapidly , in the 2000s a bog standard petrol engine would do 300k easily and a diesel more , now in 2024 a petrol wont usually get to 80k and a diesel is lucky to see 60k , and they call that progress ... I dont really think its moving forwards at all.

Please tell me how you have the source of this video, I would like to buy it. And thanks so much if you share for me full serial. Please and thanks again.
ERREUR de sens de rotation de la pompe !! 👎🏻 Dans la vidéo, elle tourne en sens horaire (vu de l'arrière de la pompe) alors quelle doit tourner en sens ANTI horaire !!
It’s always amazing to me how much of the sound of the VW TDI engines came from the injection pump itself!
Das ist eine "normale" Saugerpumpe und keine TDI.
@ many TDIs had rotary pumps, eg my 98 and 99 Jettas.
Love these films, please keep them up and post any others you have or find. Thanks!
Certainement un des meilleurs documentaires sur le fonctionnement des pompes Bosch Ve !!! 👍🏻
Super bien expliqué et détaillé !! 👌
Excellente vidéo !!

@@Nudnik1 Exactly, that's the whole point! I bought a new turbo charger better than the old (oem) one .

@@Rx7man Ohhhh, someone has a NEW cat! Fancy.
I like my first gen.
@@poppaluv I've got 3 of them now.
00:40 Damn when I heard that reminded me of my golf MK2 TD....
i would pay money to see manufacturing of these parts/pumps
Amazing how things were engineered before computers took over
"never adjust the full power screw while pump is on the vehicle" 🤣🤣🤣🤣🤣🤣🤣
It's best done on the vehicle.
🤣

'Leave the full load screw alone'....so like uhhhhh? That doesnt translate into thai.
amazing stuff
thanks, just what i needed
ดีมากครับ

I always want to adjust my 4jA1 engine pump until I watch this video, it does not need my amateur skill to do so :D
Thanks
Thanks you so much
Instructions unclear just bought a p pump
This would be way more understandable with an animation.
Technology is the best
If you were paying attention you’d notice the video is dated 1990. This was the best they could do at the time.
Thank!
Bravo
I don’t know what it is with these old diesels. They sound like they’re a bad pot hole away from blowing up.
Mine sounds good, no problems.
A diesel well tuned diesel engine sounds great. Music to my ears.
New common rail computer control Diesel s make all this obsolete .
New tech much simpler more efficient easier to troubleshoot also.
and far less reliable
Not to mention EUIs and EUPs
HEUIs....etc

Whan in tapit clearance in bivaid in 90 digre
Thank you so much!!!!!!!!
Seems very different from VE pumps on first generation Dodge Cummins.
If you've had one apart they actually seem identical.
It’s all exactly the same, only difference is the Cummins has the LDA controller on the top of the pump
OPEL PUMP.
Das ist eine VE-Pumpe für den VW-Golf
