Bosch VE injector pump leak out of the breather. Can it be fixed?

[@206898195311]

My pump was leaking just as described and sure enough when I took it apart everything Mike said was spot on. I decided to take it to a professional who had it done in a day. He explained to me how he done it (punched the shaft out via the ball bearing and reseated it). Personally this is best left to a pro and focus on something I can fix. Thanks for the video Mike.

[@gazzafloss]

G'day Mike it's been 50 something years since I was trained on diesel injection pumps at Tech College. If you were closer I'd send you a stuffed pump to play on, I have some spares ranging from re-sealed and ready to go complete unit to spare bits only. I've always found the Bosch VE full mechanical pumps I've tackled pretty easy to work on, not come across the problem of that diaphragm chamber flooding, but I have heard of it before. I have been re-sealing pumps for a few mates, fellow Landy owners, over the years to keep their vehicles alive, for $20 au, you can buy a kit to replace every seal in the VE. The pumping elements seem to go on forever if you keep the filters serviced. Some good advice, don't "muck", (or a word that sounds similar), with the factory pump settings.

[@BritannicaRestorations]

Totally! I can build pumps blindfold but setting them up needs a test bed and at C$600 to set them up I might as well buy a recon Bosch pump! ( which is why I have so many used! ) I think guys have to get this into perspective that these pumps are over 30 years old now and parts/seals wear out I am now getting one a month questions on flooding hence the video

Hey would you know any websites that have rebuild kits for 1L Toyota diesel motor

[@gazzafloss]

@@TonyTguerrero sorry, don't know a lot about Toyota, I thought they never needed parts because they are so reliable and never break down...

[@russellbeck7596]

I had this exact problem. As a temporary fix , 5 years 😅, I removed the rubber breather and the special bolt it fitted to. Replaced that with a banjo bolt and piped it via a T piece into the fuel return pipe. As I said that lasted 5 years until now, but the O ring under the pump head is now leaking so an overhaul is needed.

[@BritannicaRestorations]

Good tip!

[@MrRobmellor]

I never did like working on a DPA pump, always sent them to the shop. The old in-line pumps could be pulled in pieces very easy so I always worked on them with great success. A good common-sense video mike. Stay safe mate. Yorkshire Rob.,

[@BritannicaRestorations]

These are pretty easy to work on but need a test bed to set them up

[@phildon5]

Thank you Mike. That explains everything perfectly. I will have a look around for a pump workshop nearby. Thanks again Phil

[@BritannicaRestorations]

Glad to help!

[@shunter3670]

Hi Mike , my 70 series in Cameroon had this problem it was a substantial leak, never new the cause until now. I got round it by fitting a return line to the tank from the breather , I also had to fit an electric supply pump to supply enough fuel. The car ran fine like this for over 5 years until I managed to bring a second hand pump from the UK. another bush fix by necessity as there was no specialist workshops

[@BritannicaRestorations]

Yes it has no effect on the performance - just an annoying leak!

[@jamesmiller3963]

Thanks for the help...just tore one of these down today and i surely went the extra steps and punched it out myself. Not an option to even buy the boost control anymore, so yes no parts available to fix...however in my various kits of o rings i did find the perfect one....also on another not the pin itself on mine had some etching so when i put it back in i flipped the pin so the wear is now inside and not on near the o ring....i did however get the throttle linkage wrong when putting back together so it had a high rev...no biggie just move a few grooves all back to normal. This was surely a pain to get out....just dont punch one ball all the way through go as far as u need to get one out and flip over and do the other....also dont have to completely remove the pin to get the arm out of the way. Ive never even worked on one of these before, with the help of this video i had it off and back on in a few hours....btw i only took the top off instead of removing the whole thing from the machine....had to make several tools though shorten an allen to get the back screw out...and also u need a 4.5 mil allen to remove the cap holding the pin in...i ground the same 5mm i had cut short and ground other end down to fit the odd size allen set. Thanks agian for all the help....literally saved me thousands.

[@peterjohnson2245]

All that and a hair cut too :)!! Thanks so much for the 2nd row door dims in your video the other day for the 110 SW, just been fitting my new B/C pillars. Turns out they had jigged them up wrong and the gap is 30 3/4 rather than 30 1/4. So cut and weld time :( If I hadn't had your info I would have been stuffed!

[@BritannicaRestorations]

You are so welcome!

[@simonrowlands7472]

See if the plug or ball is soft and drill or maybe tap to fix extractor, great vid mike

[@BritannicaRestorations]

Looks like a ball bearing to me so it will be hard

[@GregPalmer2]

Talking about pumps.l remember adjusting the mixture screw and leaving that wire locking the mixture screw dangling. I wondered why l kept on blowing the fuse on the pump stop solenoid,it was dangling hitting the top of the solenoid shorting the fuse,it took a week to find that short.

[@BritannicaRestorations]

Lol! Easy done!

[@adityapartap]

On top of the fuel linkage shaft and linkage, there are a few cuts. You need to keep track of which sets were lined up. Just take the fuel linkages off and take off that bolt. I know it's a lot of hassle to go through. And you might end up screwing up your pump if you don't know what you're doing. Plus it'll be a lot easier if you have the pump off the engine because putting the fuel linkage on is not a very easy task. It's frustrating really because you have to pull the shaft up as you push the fuel linkages down. If you don't pull up on the shaft, it'll just slide into the pump. You have to do all that whild holding the springs in place and also keeling in mind to line up the lines on top of the linkage and shaft i was talking about earlier. Bosch could've easily solved this by putting a circlip around the shaft. But i think they didn't do that because they didn't want you taking apart your pump yourself. At the end, one simple advice. If you're taking apart the fuel linkage yourself, remember to take lots and lots of photos of everything along the way. Too many photos will never hurt, you can always delete them later when you're done. If you are not able to do it yourself and take it to a shop, the photos can help them do it (useful for uncommon pumps when you don't know what notch it was set on from factory)

Hi Mike i have removed that shaft by punching it through there is a bush around the pin you can get it out with a t30 as it is a inbetween size hexagon under it there is a cup and a square cross section o ringthat i could not match i cut the cup down and added a washer to crush the o ring

[@SiCrewe]

Regarding the shaft that needs drifting out, what's it look like? Would it be possible to replace it with, say, silver-steel rod with an internal thread cut into either end so it could then be secured using a couple of small allen bolts? Add a couple of washers and you could also fit an o-ring in each end to seal it. Might be a nice little earner, supplying a serviceable replacement shaft.

[@BritannicaRestorations]

I have no idea as I have not had one of these shafts apart

Yes, but you have to get into the O ring position first without destroying the body and making more leaks

Mike, I have a generic question about a VE pump. I have a Cummins that will not start and noticed there is a tear in the diaphragm. Would you agree that this would cause it not to start? I am excited because I think I finally diagnosed it but second guessing my self while waiting on the part.

[@BritannicaRestorations]

It should still run - that is the diaphragm for the excess fuel when the turbo kicks in

[@Stu1-68]

@@BritannicaRestorations That is what I was afraid of. It’s a new pump. It was locked and I timed all gears. Bleed lines excessivly. Fuel is coming to all injectors and it will not attempt to start. Checked FSS. Will start with a snort of either.
