300Tdi Injector pump throttle shaft leak

My injector pump is leaking fuel from the throttle spindle where the cable to the pedal attaches - see pic. Its been "damp" around the spindle for months, but it now drips fuel. Not so much when the engine is running but more when its just stopped - I guess there is fuel inside it which is at high pressure.

Anyway I removed the torsion spring bit in the pic but the seal is not fitted from the outside but from the inside of the pump. So can a specialist replace the seal or not, or is it a new pump? It looks like the pump body needs to be dismantled to get at it - I'm not brave enough to attempt that.

Anyone know a specialist they can recommended in the Portsmouth /Soton area? I can feel another wallet busting episode coming on again, on top of the cylinder head costs... :angry:

Good grief! I knew and injector pump was complex but when you see that 1st "exploded" pic... :blink:

Looking through the article, the throttle shaft on that one looks to be just a bushing rather than a seal. There also doesn't seem to be much complex stuff in the top cover.

So, do I take the pump off entirely and all that associated faff and get it rebuilt, or.. do I just leave it in and whip the top off and have a look, once its all timed and locked up???? Choices, choices, it may be quicker at this rate to finish rebuilding the series 3 b4 the 90 gets back on the road - 3 wks laid up and counting... :(

Me thinks it might be worth a trip to the scrappy and having a go whipping the cover off the pump of on an old Renault or Peugeot as a trial run..

take the pump off sod trying to save the timing

I did and it had to be redone as the pump pulley moved once the pump was off.

there's an Electro diesel on Exeter

try calling to get an estimate.

a mate of a mate did mine for reasonable £ not someone I know personally or I'd ask him for you for an estimate.

Found this on google:

Looks like the shaft is fitted with an O ring and this runs in the bush. So it might just be a case of taking the top off and changing the o ring...

Anyway looks like tomorrow is going to be spent phoning round :rolleyes:

Exeter is a long way from me, seem to remember passing an Electro Diesel in Reading, i'm up there tommorow anyway so i'll check.

Well the pump is apart, throttle shaft is worn to bu&&ery, no wonder its leaks... Panda fuel injection place at Broadcut, Wallington, Fareham have all the parts on the shelf, so will pick them up 2moz. Lets hope it all works when I put it together again.. :unsure:

Les Hanson style how to do it post with pics will be on here sometime over the wknd. :D
