reb78 Posted February 7, 2012 Share Posted February 7, 2012 On my way up the m1 this morning, I noticed that I'd only got 90 miles out of half a tank of diesel! Performance seemed fine but I pulled over to check it at the services. I'm sat waiting for the rac now as I have no tools with me. It appears that diesel is spurting from a plate on the side of the pump near the engine mount. It looks like one of the allen screw that holds the plate is loose. I guess we'll try tightening it up, but has anyone got any ideas as to why it might have come loose and what other problems it might indicate?

vulcan bomber Posted February 7, 2012 Share Posted February 7, 2012 Thats a new one on me Richard cant really begin to think of a reason for that to happen.. I think there torx bolts though as opposed to allen keyed. Quote Link to comment Share on other sites More sharing options...
reb78 Posted February 7, 2012 Author Share Posted February 7, 2012 Thanks David. I'm definitely stumped if you are! I'll have to have a closer look when I get home. I wonder what's behind that plate? I'm still waiting for the rac 4hours after calling them! I've only got spanners with me, no Allen or torx bits. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted February 7, 2012 Share Posted February 7, 2012 Its where the bits for the timing advance live and the cold start if the pumps fitted with it... Tdi's arnt. Quote Link to comment Share on other sites More sharing options...
reb78 Posted February 7, 2012 Author Share Posted February 7, 2012 7 hours at Watford Gap services before i finally got home! What a rubbish day! Is the leaking plate and whatever is behind it removeable/replaceable in situ or if i take it apart will it need setting up by a specialist? I was talking to a diesel specialist near me earlier, and if they understood the part i was on about correctly, they reckoned there was an upgraded side plate that they fit to these and that i should be able to do it with the pump in place. I need to go see them in person so i can make sure we are talking about the same bits, but i';d like to take the bits with me if they are ok to remove so they can match them up.

vulcan bomber Posted February 8, 2012 Share Posted February 8, 2012 a spring, a plunger and a seal iirc.... If you were closer i'd let you dismember my bust injector pump before having a go at yours. Quote Link to comment Share on other sites More sharing options...
reb78 Posted February 8, 2012 Author Share Posted February 8, 2012 Thanks. Nothing fell out when i remove the plate (thankfully!!) I think the spring is on the other side and the outside of the pump seems to have the end of the cylinder that sits in there. Here is a pic of the offending plate on the pump. (you can see the diesel everywhere!) This shows the problem along with the replacement seal and a modified plate: The modified plate has a lip that sits inside the seal - i guess it ensures the seal is in the right place and doesnt get pinched. The other modification also seems to be that the replacement bolts are about 3/16" longer than the originals This is the replacement in place before i nipped the bolts up. I put some threadlock on the bolts, although i'm not sure it'll work too well as it was difficult to get the surfaces/threads clean of all of the diesel (plus it was bloody cold and my fingers were numb)! I think that the plate outs some pressure on the cylinder, so with the spring on the other side of the pump, perphaps this should stop the bolts shaking loose again. The diesel place thought that one reason why these may have come loose could be due to air in the pump - apparently that would make the cylinder that sits across there chatter against the plate when in use and could loosen the bolts. I've bled everything though and i cant see any reason for air in there now. Taken for a test drive and all seems fine. Quote Link to comment Share on other sites More sharing options...
JST Posted February 8, 2012 Share Posted February 8, 2012 glad you got it sorted. my last tank full did 68miles on half a tank - that will teach me to check the filler is on! Quote Link to comment Share on other sites More sharing options...
reb78 Posted February 8, 2012 Author Share Posted February 8, 2012 glad you got it sorted. my last tank full did 68miles on half a tank - that will teach me to check the filler is on! I had to console myself that since I did the return journey on a flatbed I wasn't paying for the fuel to get home! The diagrams Chris came up with on your thread were helpful along with VBs advice.

reb78 Posted February 9, 2012 Author Share Posted February 9, 2012 Well, in my normal OCD fashion, I was worrying about the loctite not being good enough on the bolts. So, I got up early to go out and check them this morning and thought I’d remove them one at a time, clean the threads properly and re-loctite them to stop them shaking loose again. On replacing the second bolt, I managed to mess up the head completely as the torx bit twisted in the head because i had it at the wrong angle. Luckily it came out ok and I put one of the originals back in. Now the OCD has kicked in that the 1/8" less thread (not 3/16" as above) is going to make all the difference with keeping the bolt in place! Bloody thing – if i'd not touched it today, I suspect it would have been fine!! I shouldnt worry, but i need to go from London to Taunton and back later today, so i need to make sure it gets me there and back! Quote Link to comment Share on other sites More sharing options...
stephensmith Posted May 10, 2013 Share Posted May 10, 2013 Hi Reb78, do you have a source for the modified plate then? I suspect I have to carry out the same task. Thanks. Quote Link to comment Share on other sites More sharing options...
reb78 Posted May 10, 2013 Author Share Posted May 10, 2013 Ok. James (JST) post that i refer to above is here: http://forums.lr4x4.com/index.php?showtopic=74279&hl= GBMUD posted some useful links in there that will help you ID the part easier. I rang Wade Diesels in Hoddesdon for the part: https://plus.google.com/117299679238326421375/about?gl=uk&hl=en#117299679238326421375/about?gl=uk&hl=en they dont have a website but are very helpful on the phone. I think if you describe it as an 'upgraded side plate for the bosch VE injection pump' they should know what you mean or be able to find out - its the modified side plate, a new o ring seal and slightly longer torx bolts that you need - they sold it to me as a kit and IIRC it cost around £30.

stephensmith Posted May 11, 2013 Share Posted May 11, 2013 Many thanks for the reply. I'll be away for a week and can then get back to the problem. Thanks for taking the trouble to post up the info. Quote Link to comment Share on other sites More sharing options...
stephensmith Posted May 20, 2013 Share Posted May 20, 2013 Does anyone have an exploded diagram showing the components of the VE4/11F 1900R347-1 injection pump for the (1993) 200tdi? I'd just like to check the position and number of O-rings on the screw that locks the pump spindle. I've ordered a kit for the upgraded oval plate from Wade Diesels, Hoddesdon ( info from REB) but it looks for all the world as though the fuel is dripping from this lock screw. Just moving on to whether a couple of copper washers will at least confirm this. My locking screw came out with one green O-ring but.....maybe there are more in there! Thanks.
