I can dream of hearing this version over a video of players fidgeting before an NHL game, especially at the end when a player is inside the net nervous.
I guess this was before tredeau fucked us all for the next forty years…. Did you know he changed the anthem? Then put a picture of himself in our passports? And his mother is a whore
I've been around MACK TRUCKS since the thermodyne an the maxidyne so can somebody explain it to me what is the difference between the Robert Bosch injection pumps and the American Bosch injection pumps.
is there someone on this video that can answer a cav question i have about our case580e backhoe? the engine will only run when i operate any hydraulic, as if the hydraulic load causes the pump to work i guess? somehow i find this pump very complex and want to understand before i take it all apart, this is my current job and i dont know what to tell the boss
nice job,,,,in the test room, is the test done with a prototype injector? or what the engine has...how will we measure the pressure of the transfer pump? and how will we know if the hydraulic head has lost its performance..thanks
@@nikutb6798 That is a very good question. On the vehicle its not going to be easy. Given that, in a conventional diesel engine, the injection system isn't trying to maintain a given fuel/air ratio (as it has to in a petrol injection system). The action of the governor probably masks moderate levels of leakage in the high-pressure pump. At a given throttle setting, if the RPM drops slightly because leakage is reducing the delivery to the injectors then the governor will open the control valve slightly and increase the fuel being delivered. I suspect a badly worn high pressure pump shows up first at idle where there is more time for the leaks to have effect and the fuel delivery per pulse is low. Back in the 1960s I did, as a kid, spend about a week watching what went on in a fuel injection repair shop and the pump testing was done without injectors on the outlets but with the outlets simply piped up to a set of measuring cylinders so that the flow rates could be measured. Presumably the assumption was that the pump, having been refurbished, wouldn't have any excessive leaks that would affect the delivery under injector back-pressure. Wear in the transfer pump is, I suspect, not a major issue. The transfer pump on a DPA pump, from my calculations, circulates through the regulator valve about 15 times the volume delivered by the high-pressure pump under maximum load. So the system should perform fairly normally even with moderate wear in the transfer pump.
never mind Perkins engines, we used dpa pumps when i worked at AEC ltd on the av 505 engines and on some av760 engines dependant on customer requirements,
Very useful video. What I don't understand is how a worn pump can be reconditioned. As it wears presumably the fuel pressure within the pump housing increases and so inevitably the drive shaft seal will eventually be overloaded and leak into the sump. So unless all the worn components are replaced there will be no improvement in an old pump.
The purpose/reason for me to be having/possessing a Pluto TV cellphone app is that: I'm someone who has been searching for adult reality TV shows, and that stage holds no contest. Therefore, there's to be no competition in these reality TV shows. Jersey Shore was like that.
The regulator valve allows the pump to be primed using the lift pump priming lever as far as filling the pump casing and the transfer pump but not the high pressure pump or the injector lines so the final stage of priming requires cranking to operate both the transfer pump and the high pressure pump. The lift pump priming lever is missing on my tractor so I have to do the whole priming job by cranking. With a fully charged battery this is no problem.

Fun facts: not only do present day so-called 'Europeans' have absolutely no genetic relation at all to the earliest people of Europe, but also that various people(s) of Europe had it all to themselves for over 40,000 years and in all that time had practically zero meaningful technological achievements despite having more than ample time. So what's all the fake news of an imaginary 'migrant' 'crisis' about then when the present day illegals aren't even _the first?_
Hi all, I am trouble shooting a Bristol Taurus crawler (1950s era) which will only operate at full RPM. Perkins 3cyl engine, CAV BPE injector pump. Wondering if anyone has advice what could be causing this issue - the engine had been run out of fuel immediately prior to this issue arising so I am wondering whether something from the bottom of the tank has blocked/stopped something in the fuel injection pump? Many thanks

Love how they say beware of injector pressure easily perforating your finger whilst at the same time telling you to test the end of the pressurised injector for leaks with your bare finger.
Every other video about fuel injection pumps should be required to have a link to this original Perkins technical sales/support film. The real question that everyone has is how do I get air out of the thing so the motor will start. Now I know what is going on inside the pump.
Excellent video, thank you very much! I am in a process of converting my marine Perkins 4.108 into a generator work horse and was trying to find information on CAV DPA hydraulic (which my motor has) and on mechanical pump (which I think I should get for generator use). This video explains all I need to know about these two types of CAV pumps.
