Hello,
Finally , my swap from Lucas CAV to a BOSH VE is a success ...
This is my post in French ( for pics) :
https://forum-auto.caradisiac.com/topic ... /#commentsIt's a party, because the truck finally restarted with the BOSH VE type pump, I didn't believe it anymore, but it restarted straight away!
So, in order I first reassembled yet another Lucas CAV pump, which started to restart very well every time,
this one consisted of a front part found at the right place at a discount on an H.S pump and the original hydraulic module, of which I had unseized the 4 pistons.
On the other hand, curse, the pump remained fully accelerated, all the time, nothing to do, she didn't want to know anything. However, it seems to me that I have reassembled the part of the acceleration arm correctly, I don't know if it's that or the front part which is causing this. So I had changed all the seals, it was no longer leaking, but accelerates fully, I don't know why, but starts flawlessly.
So, I said to myself "Okay, I've had enough, I'll try the BOSH VE injection pump" which I found cheaply on LBC.
So, in the meantime, I'm rebuilding another Peugeot Boxer truck from 2003, because I thought the transit wasn't going to start again.
Then, I bought AGAIN another rather expensive BOSH VE pump, rebuilt by BOSH Germany, but not too expensive anyway (around four hundred), because I had sworn to myself never to abandon this truck.
Then, 1 month later, I fitted the first BOSH VE pump for 160 euros that I found, no longer believing in it at all, I had to tighten the timing belt a little by pushing the tensioner roller, because the pulley is not quite the same on the BOSH, it has 4 holes, but the same number of teeth. Note that I used more than 100 Rylsans collars in total, to block the timing belt each time, so as not to lose the adjustment and I carried out perhaps 12 or 15 reassembly-disassembly of the injection pump LUCAS CAV, all in all, an exhausting thing, whereas with the BOSH, it would have started again straight away...
Note that I bought mecarun and injected it with a little diesel into the BOSH P.I using a bulb and waited for a month, if so, it played a role in the success .
After doing my research on the Ford Transit forum in English, I understood that the BOSH engineers must have created this pump for this engine, and that it was compatible whether it was the LUCAS CAV, and the BOSH VE Pump, except that the teeth of the PI pulley are something like 0.3 mm instead of 0.25 mm. We see in the following photo that the teeth of the belt do not go "all the way".
Then, my fear was that the BOSH VE pump was very hard to turn by hand, normal because it is not at all the same system as the Lucas pump, there are big springs inside it seems.
but I was afraid that it would break the belt, or fatigue the starter, well no, the D-day arrived, an hour ago and it started in 2 seconds, after carrying out the bleeding procedure on the 4 injectors ( Start loose injectors, then retighten)
The important thing for transit owners is not to confuse the LUCAS CAV pump from 1990 and the electronic LUCAS EPIC pump which, it seems, was not too good, I had a LUCAS CAV, which seems to be reliable, but can leak and in these cases, it's annoying. As I was a bit nag at the beginning, I tightened too hard without taking into account the torque and I damaged the original pump, whereas I could have started again by being more careful, just by changing the seals.
Well, I haven't driven it yet but the VE pump already has a better idle than the other, and makes a nice noise, it's a party, I'm on cloud nine!
For the hoses that weren't long enough, I just bought some and it fit into the usual rigid hoses with a rylsan. You also need BOSH tubing instead of LUCAS.
I had bought an electric pump on ALI, just in case, but there was no need, it started, and it accelerates!!
My question is that I hope that the belt which has smaller teeth will not jump, because they say that you also have to change the other pulleys so that they are all in 0.3mm, but will find a pulley like that in 2024!
So either, you have to strain galore, but I don't dare, or I leave it like that and try to ride...
So, I find myself with a VE pump reconstituted by Bosh Germany and 3 Lucas CAV pumps which are not working well to resell...
Thanks again to the good person from the South of France who sent me the whole package, VE pump, Bosh and Pulley tubing, without that, it was ruined!
I think the Lucas CAV is a great piece of material, and starts really really nice, but I was a rookie and did not do things well to fix seals.
We can see that the Lucas pump started well because even when turning by hand, a jet comes out through the 4 outlets, step by step and it is noticeable. I have been able to acquire a lot of know-how and delicacy in handling the injection pump since these 4 months of breakdown. I now constantly work with vinyl gloves and change them constantly (Packs of 100).
pulleys should be ok ?
