diesel pump change
diesel pump change
My 1700 non turbo Bosch diesel pump has sprung a fuel drip from the head end..... the pump is still working fine...... Is it easy to change the seal?.....I have removed the pump now.... Or am I better changing the pump,,,,, I do have a couple of turbo diesel pumps...... Will one of these do the job with no dramas?

Re: diesel pump change
wow - finally got my 1.7 TZD back, with a leaking fuel pump and log back on to search the threads and see this No idea on the answer to your question but if you fancy selling one of your turbo diesel pumps I may very well be interested. I've never changed the seals on one of these but did do the seals on a diesel pump from a 2.2 toyota lucida, it can't have been too hard as I managed it. A little phased by the timing belt element on the BX, I'm hoping slow and steady works but any tips gratefully received.
good luck and hope someone can answer your question soon.

Re: diesel pump change
As you allready have the pump out of the car, the change of the front seal is a 5 minute job. Been there, done that. First tried it without removing the pump but it was impossible, as there was not enough room to get the old seal out and drift the new one in straight. When buying new seal you need to have the dimensions from the old, as there's two different axle sizes. My guess it's the smaller diameter, Xantia pump has the bigger.

Re: diesel pump change
Sooner or later the seals will leak on all BX diesel pumps if they're on their originals, which many probably still are.
eBay kits should have all the seals you need - the pump head can be fiddly, pump needs to be help upright as you do it IIRC so nothing falls out!
Might be better to bite the bullet and send it to Diesel Bob or a local diesel specialist who'll probably enjoy working on older mechanical pumps for a change! They should also, after resealing run the pump through a test sequence... I had a Bosch TD pump tested and the front and head seal replaces at around £170... I had Diesel Bob fully reseal and test an early Audi TDI pump for our £250 - they'll do it by post which is handy...
If you want a really quick fix though for the head seal you could run properly made 100% biodiesel as it tends to swell rubber seals and stop these sorts of leaks, whereas pump diesel tends to shrink them.. I got several years out of my audi pump this way - until the biodiesel though softened the driveshaft seal so it leaked!

Re: diesel pump change
Has anyone got a step by step guide on how to actually change these seals? I need to do the top seal in my pump & as I have never pulled one apart before it would be useful.
Also, would this seal leaking cause the car to run somewhat rough when first started or could I have another air leak somewhere?
Thanks in advance.

Re: diesel pump change
Well I can report a little more...... I too would like a guide on seal replacement! I obtained and replaced the head seal... Refitted the pump...... Car wouldn't run!!!!!! So in the end I fitted a turbo pump I had..... It works and the car is useable... But in my opinion only as a stop gap measure.... Somehow the car isn't really right... It needs the correct pump!

Re: diesel pump change
I have found this site, that explains in some detail how to rebuild the injector pump. Might be of some use.
