It has already been decided that the nozzles will be replaced. Before we can do that we need to clean what will be reused and measure these components to make sure they are still within tolerance. There has been a lot of talk in all this about 'pop' or 'crack' testing to ensure that the needle...

Right...before gaskets get popped....lets continue...

ok steady on..im not disputing that or anything wammers said. just hang on..I'll prove what im on about. It is simpler than you think. if you replace certain things. and nobody said anything about cheap poorly calibrated pop testers. Not the sort of kit I use. This is getting ahead of what I'm...

true..all true..but under certain conditions and with certain issues not addressed. I will explain in the case of THIS injector.

hang in there...these are a bit different. and yes. your right injectors do need to be shimmed correctly for crack pressure, this i do not dispute. but I am not giving away the ending yet! Right coffee in my cup!

and you will like these injectors better by the time im done writting up. ;) they are soooo easy!

ok so this got up my nose a bit I'll admit and this was the quote I meant to reply to.

lol just being polite and answering concerns raised. ;)

Right, so here we go! I wont go over why I am doing this, I think that's clear enough and the pics speak for themselves. Suffice it to say that I felt the need to change my nozzles in my 1997 Range Rover DSE with 119,121 miles. I wanted to go all technical and reference everything right down to...

For those of you that have read this far and have not seen the posting that follows, please be patient it is going to take me some time to put it all down for you but it will be worth it! I will not close till I have finished. I did not intend for this thread to turn into a 'how to' and that was...

wammers Ty for your input. As it turns out, in this case, shimming is 90% of the time unnecessary when replacing the nozzle assembly in this type of injector. Please read the rest of my posting today and I will explain with science! :)(sorry forgot to click insert quote so had to name you in edit)

Sorry it has taken me some time. It has been an effort to find the answer to this question as it turns out , nobody knows! I have sent an email off to Bosch to find out the answer as I dont like leaving things undone however I do have an answer for you. Please read the rest of my posting today...

some of the best mechanics and engineers I have worked with have never had a formal education. school can only teach you to read a book. experience teaches you to fix machines! That said, I am grateful for all this, I just bought myself a pop tester. will be here by next week and I wont be...

First of all, I am ASE certified, not a dyi mechanic so less of it. Unless that time I spent at college 25 years ago was all a dream. and second, I am sending them off to be pop tested. I am just looking for a base setting for the spring tension before I send them off. I also intend to match the...

I called the guy back and asked what the tor_ue seting was and he gave me a 'I think 60 nm should be fine' answer. Obviously that isn't good enough! The wrong tor_ue setting will result in incorrect needle operation and could make the injector useless. So I have called Bosch UK who were happy to...

pretty standard stuff for an horologist. Thats what I studied for thee years at university. I make all that by hand and to that standard. i also design it and blue print using drawings I make both by hand and with solidworks 3D modelling. to BS888 standard. 36 disciplines that I will spend the...

not yet. sorry forgot to ask the guy. im gonna call him when the nozzles get here. should be tuesday. Ill let you know when I do.

ANYWAY......lol there shouldn't be an issue..I'm cleaning a precision piece of equipment in a machine designed to clean precision equipment. As long as I change the fluids before cleaning a far more precise machine,like a watch lets say, there is no issue. :P So the results are in, I can clean...

lmao guys. she's mine hands off :P btw....there is a piece missing in my exploded view. the heat shield is a separate component from the nozzle retainer. I just found it after running the injector through one of my ultra sonic cleaners. I'll show a pic later. (of the heat shield...don't get...

I bought a brand new 2002 td5 110 double cab Black edition, in 2002, I got 35 mpg doing 75 down the a2/m2 route to sheppy daily. I was impressed for a barn door.
