406 lucus diesel pump

Does anyone know if it is possible to reduce the amount of diesel the
pump delivers to the injectors, on the 406 2.1 fitted with the lucus
pump. and if so how

 

Give Watson Diesel a ring on 02088793584 -02088793861 they are very
helpful..

 

IIRC
There is a large plastic disc on the side of the pump.facing the
radiator,unscrew this disc,
inside is a bolt with a Allen key head, I think its 4mm
and its also very tight so don't use the ball ended type Allen key, use a
small mirror to locate it,,
please be aware, there is no actual setting for this adjustment, its purely
trial and error, but I have done it many times, looking for more power,
you will need to turn the bolt ANTI- clockwise, to reduce the amount of
fuel,
it may take a few goes before you notice a depreciation in performance, or
until you achieve what your looking for,

in the haynes it states,The maximum engine speed and transfer pressure
settings.together with timing access plugs, ARE sealed by the
manufacturers at the factory using locking wire and lead seals.DO not
disturb the wire,Also do not attempt the timing procedure unless
accurate instrumentation is available,for carrying out pump timing
should be left to your main Peugeot dealer.SO IN THE WORDS DONT PLAY
WITH IT UNLESS YOU KNOW WHAT YOU ARE DOING...

 

Totally agree Chris,
I don't think the dealer will make any kind of adjustments to the pump
though,
basically because main dealers do not have a training schedule for pump
maintenance and repair,
so most technicians don't know what goes on inside the older type diesel
pumps, unless the tech, has studied it himself,
The earlier suggestion about visiting a diesel specialist is the best
option,
IMHO

So why did you suggest a possible solution 2 days ago? Just asking out of
curiosity.

Hi I've had a look at the pump and there is a round disc with a plastic
centre and also a very large nut with a pained seal on it would either
of these be what I'm looking for ?
respects

 

haynes,says that that is the plastic disc which you do the timing.so i
think it should be left to a person that knows about diesel pumps and
timing. if you play with it u might muck it up and you will have to pay
lots to get it put right.

 

Thanks for the advice but does anyone know how to ajust it.

 

YES DONT TOUCH IT!!!!!!!
