[diesel_mercedes] Injector Pump Elements

 



Indeed ! .

O.K. , here's how it went :

I got home and set up to clean the new used elements and parts , they were four of one typ and one of another.... all had the same part number but the machining on the one different one was clearly done differently .

All in good looking shape and fitment but all had a thin coating of fine black film , easy to clean off , I always clean the middles of the springs too as crud likes to hide in there and cause problems .

I took the # 1 fuel pipe off and the element out , (I bought a nifty telescoping magnet thingie to easily remove the elements with) , swabbed down inside the IP and lo ! no dirt .

I guess the startron I've been dosing it with got it all out .

The element in the car has a slightly different shape than the ones I got from the Junk Yard so I chickened out and polished it and re installed it with a third different Junk Yard fuel pipe , buttoned it all up and started it up , it still weeped in pulses so I shut it off and gave the 17 MM nut one last yank with the wrench , wiped up the leakage and tried it again , success ! no more leaks .

Sadly the left side engine shock absorber mount died from the Diesel fuel dibbling on it , these are NOT CHEAP but I'll have to find some new ones , maybe aftermarket .

It still smokes of course , I need to find a good clear image of how the elements are assembled as you can install the ring part upside - down , I don't *think* I did but I'd love to make sure before I go back in and change all the current elements out because there's RUST on them ~ . I knew this car had water in the fuel when I bought it , I polished the rusty area as best I could but we're talking about really fine clearances here so I'll give it one more go and replace all five elements , valves and springs before I give up and change out this old beat up injection pump .

I'm at least happy it's not leaking anymore .

It smokes mostly when the turbo spools up and boost passes 5 # .

I really need to figure out how to take macro pictures with the iPod , or get Tom to come by with his new digital camera as the details of the parts I am sure would be fascinating to all here .
