It's from in here http://www.aulro.com/afvb/local_links.php?catid=7

And Ian's tune up of the Bosch pump will have some useful info here http://www.aulro.com/afvb/attachment...ng-20rev.2.pdf

Thanks Rick,there's heaps of info on how to tune the pump but bugger all on how to fix them once someones stuff them up. Pat

I don't reckon the Bosch specialist measured the lift correctly in the first place because you said it was 1.2mm initially here. I've had mine changed from 1.54 to 1.6 (it's an auto, as per JC recommendation) and even that difference of .06mm made it sound and run totally different.

It is easy to set the diaphragm to factory. It has 180 degrees of adjustment, that is, if you start at the least offset position, the most offset position is half a turn, and the factory position is at exactly halfway between the most and least offset profiles.

If the starwheel and smoke screw have been fiddled with and there's no records, then its pump dyno calibration time to get it back to factory specs.

I think (I reiterate - I think) that the standard position for the diaphragm on mine was with the dot marker at about 1 or 2 o'clock (which is the same setting as 4 or 5 o'clock). The minimum setting is with the marker at 3 o'clock. As B92 8NW says, there's no telling where the starwheel and smoke screw were. Basically, if it's smoking (or smelling like raw fuel ) at idle or on take off before boost builds, start backing the smoke screw off about half a turn at a time (that's a quick and easy adjustment). If it's smoking as boost is building, start backing the starwheel off, maybe a quarter to half a turn at a time. It's not hard; just requires a little patience and time.

I pulled the lid off the conpensator and the diaphram was past 12 o'clock so I pulled it out and the wear mark on it had it in the 11 o'clock position.I put it back in at 11 and took it for a drive and there's no more smoke and it didn't smell of diesel this morning.I'll leave it alone and do some more driving and go from there.

I'm still narky about that. Pat

HI,
Before you go messing with the pump, have you checked all the clamps and hose from the turbo to through the inter-cooler and back to the engine?
I had a problem with no power and a black smoke screen and when I looked the top hose to the inter-cooler had come off.
Hope that helps.
