    Default 504 Ti cold mixture adjustment

    Hi all,

    Have had my 504 front injection pump overhaulled by Geoff Battersby in QLD (who seems to have done a great job!), and then took the pug to my local for an oil change and "tune-up". It seems that once my mechanic touched the mixture he couldn't seem to reset to how it was.

    It occurs to me that Geoff must have tuned the mixture when it was cold and the pump was off the car. Anyone know the exact setup of the mixture screw and idle bleed valve?

    Cheers,

    Have you contacted Geoff about this? Or talked to the guy who did it to find out exactly what he changed?

    i personally can't see Geoff doing the job incorectly after servicing peugeots, and especially the older ones for so long. So i would say like you said it would have been a great job.

    we know the Battersby family personally, and i can atest to the fact that they are great at what they do.

    as for the mechanic who serviced it, was it a peugeot specialist.. knowing the problems all be it reversable ones, i would never reccomend taking a 504, let alone a Ti anywhere near a mechanic that didn't know what they were doing around one.

    Luckily enough we know these cars inside out, but aparently the 'rambo has allready steared you in the right direction so i will leave it at that.

    Geoff did a great job, I'm not contesting that. He's in hospital at the moment (best wishes to him) so he was uncontactable. The guy who did it is a French car specialist. And he took it through the whole mixture range and could not get it back to where it started. Anyway, hopefully Pugrambo has info that will help without specialized tools.

    Cheers,

    Chris.

    I don't understand why the injection had to be touched... was there something wrong with it?

    You seem to say it was a good job... and the cold start adjustment is one easy adjustment, readily reversed if you get it wrong.

    ok i can't find the other documentation i was looking for so i'll go through it for you

    bear with me as it could be long winded

    you will need a flat piece of steel 8mm thick

    now asuming no one has touched the throttle butterfly i'll leave that at the moment but if you think they have then let me know

    now then you can't adjust the idle mixture cold on these pumps, just doesn't work that way

    they need to be adjusted at operating temp with the fan engaged preferrably and then turn the engine off

    you should be able to place the 8mm piece between the enrichener lever and the locknuts

    if not then adjust accordingly

    once that is done restart the engine

    now with the engine running and idling at 900rpm (if it isn't let me know) you need to very slowly raise the enrichener lever by hand and the engine should raise it's idle up to around 1050 before dying again

    if it goes above this then it is too lean and below this it is too rich

    if it is too lean then you need to locate the other screw there that comes out next to the enrichener but near horizontal and screw it in 1/4 of a turn at a time and repeat the above process

    if rich then you need to screw it 1/4 of a turn out

    repeat untill you get the results as above

    once all this is done you then need to adjust the air bleed back to 900rpm if need be and then don't touch it

    if you need any more help then don't hesitate in asking

    this is THE way of getting the mixture set on the 504 TI engine

    all of this is of course so long as all the ignition system is in good order otherwise you are going to be chasing your tail

    ensure you have a plug gap of 26thou no less no more

    no problem

    just ensure the ignition system is in good order and ensure you run a good quality coolant/rust inhibitor as you don't want any thing corroding away

    also ensure all rubber lines are in good order and if you haven't put some hose clamps around the rubber unions between the inlet log arms and the manifold yet do this as well to prevent sucking in any unwanted air

    these rubber unions perish over time and loose some of their sealing

    i always used to place a little jointing compound in them then put it all together and then hose clamp just to make sure

    the only air you want to enter the system is through the throttle body in 2 places, the butterfly and the air bleed idle circuit of which you have to be careful when and if you pull the big plug out as there is a seal in there with a very small orifice that can be lost easily and if it is lost you will have no end of trouble trying to get it to idle properly nor be able to adjust the idle

    very simple system but one that can be very easy to get wrong if you aren't careful
