205 TD : dépose pompe d'injection

Bonjour à tous !

C'est pas encore fini avec la 205TD. La distribution est déposée, mais je ne
vois pas comment je peux déposer la pompe d'injection : le troisième écrou
est quasiment inaccessible. Les deux autres OK, mais celui qui est en bas
(vers l'alternateur) c'est pas facile... Quelqu'un aurait la procédure ?
Est-ce qu'à enlever la poulie je risque de décaler la pompe ? J'ai bien la
procédure dans la RTA mais elle m'a pas l'air très claire.

 

Hi Jeff,

Pleast to hear from you again

Ok, here's the story... I'm still facing problems with my brother's '91 205
DTurbo, there's a fuel leak on the Diesel pump's driveshaft, this involving
the fuel to leak on timing belt down to the floor. Not fun.
Now I've removed the timing belt (it was a bit playing with my nerves :-( ),
but the procedure to remove the Diesel pump isn't that easy : they say I
have to remove the three front screws (the ones which are on the belts side)
and the back screw, OK I can see them all, but the third screw, which is
rather on the bottom-side seems impossible to reach with a wrench:-(
Do I need a special tool ? Do I need to remove whole engine (I hope not) ?
Another point, now the pump's driving gear is blocked, could I remove it
(the 2 little bolts + the big bolt) without losing the pump's advance setup
?

 

Hello,

Of course I typed with my fingers not on the good keys Read "Pleased to
hear from U again".

 

or you can sometimes "just get onto it with a 13mm socket and wobbly type
extension and ratchet
once its loosened you can spin them off with your fingers
for what its worth our diesel specialists here in the uk change the seal
with the pump fitted after removing the pulley

 

Hello,

Thanks. Finally I managed to remove the whole pump mounting (it's just
secured with 4 13mm bolts) using a 13mm wrench.

 

I had trouble getting at the third bolt too. After trying (and failing) to
get a spanner onto it for 20mins I took the alternator off and then it was
easy to get at with a normal spanner.

Hello,

I didn't need to put the alternator out, as I finally took the whole pump
mounting plus the pump out. The problem was to take the fourth bolt out
(13mm too), because a hose was in way, and a a 13mm spanner was just too
long (hitting the metallic timing "cover"), but I finally took it out with a
little unbolting angle (due to the steel plate, which was agressive just
where I needed to put my hand).
Finally took all this out, and still have 5 fingers at my left hand Now
I've done it once, I guess the refitting will be a kind of joke, say 1 hour
for pump & pipes... a lot more for timing belt :-/

 

you dont have to remove timing belt when removing pump
leave the pulley on the timing pins/bolts

 

Hi Jeff,

Sorry, I haven't seen your post...

I thought it was necessary. Well, we replaced the timing belt, of course -
not the biggest part of the bill, servicing a Diesel pump costs a lot (it
was around £400 exc. VAT, most was labour (~£300 exc. VAT). Ouch !
BTW, we kept the tensionner, as it was just some thousands kilometers old.

 

no worries as long as your happy with the repair
as a rule these engines run forever
did you see the article about the 309 that had done over a million miles?
think it was a french one

 

Hello,

Works great, took its mot, my brother's called me today, still no problem.

True. Oh, you certainly know I'm a XU/XUD enthousiast

No, I haven't heard of something concerning a high mileage 309D. I've heard
of such a case concerning a Golf Diesel (which makes me think a 1,000,000 km
Golf can't have its original gearbox). I guess a 1 million miles 309D is at
least as possible as a 1,000,000km Golf. Damn, I guess I really hate VW

 

Hello Jeff,

BTW I can tell you why there was a fuel leak on pump's drive end : worn
shaft seal. Not amazing for a leak, huh. But the seal destruction was caused
by the use of a Bosch output screw on the Roto (Lucas) pump. You probably
know the Bosch output screws have a really smaller hole for fuel return,
compared to Rotos. This causing an overpressure, which finally blown the
seal. C'mon, buy a used car :-(
Really a stupid fail, IMO, but why would my brother (had a B-Tech 1st as an
auto mechanic) have a look to the fuel return screw ?
