you just need to note the position of the throttle spindal when you remove the pump top.allow your self a couple of hours to be on the safe side.

hi pete,
i had the same problem on my 405's pump after I changed the engine. Didnt notice it until it was in...
I dont know how bad yours is, but if you remove the 10mm nut on the throttle spindle and turn it back a bit with a flat blade screwdriver, then tighten it up again you should be able to tighten it down enough to stop the leak without a seal. Its tricky though as if you go too far you will hear the idle raise and you will have to start again.
mines been cool for over 15000 miles now though and it was really squirting out!
In fact from memory, the lucas guy told me it was a non repaceable bush, and that it was wear on the spindle itself, hence why i tried so hard!
Cheers

Theres a kit for roto pumps consisting of a bush and an o ring, easy enough to change, theres more than likely one for Bosch too, just clean everything off before you start.

Hi,
For the bosch pump. Take off the locknut so you can move the arm seperately of the spindle (the rod sticking out of the top of the pump with the screwdriven top). So that the splines are not contacting, you dont have to remove it completely. Then turn the spindle back a bit with a flat blade screwdriver. You will notice the idle has dropped. Then put the arm back on and tighten up the 10mm nut. It will pull up the spindle tighter against the seal, but make sure you dont let it turn too far or you will raise the idle. It may take a few attempts to get it spot on.

Yes I got it from a local diesel specialist for about £7 at the time, the kit was a bush, a new spindle and an o ring, remove pump top, drift out old bush drift in new one, refit with new spindle and o ring and no diesel fuel dribbling down the front of the engine, good luck sourcing the parts.

hi guys
Thanks for your info well ive just spent the afternoon replacing those seals and i was surprised just how small they are
took off the levers removed the top of the pump and replaced the seals on the spindles and as tonespeed said a very fiddly job anyway ive done it now and the leak is gone [:D] thanks stewart for your help it was that which helped me a great deal and also mrbump for your help. i went to one specilist and he was going to charge me £60 for doing the job and he said he would,nt sell me the the kit as people make a right mess of it! anyway i rang somewhere else who did sell me the kit for £5 now ive done the job and £55 better off [:D] and bit more experance all in all the job took me about three hours
anyway thanks agian
