    C250 TD 1998 heavy black smoke after seal change fuel pump pressure valves

    >>(don't ask me how I know!) Is this a tale to be enjoyed with Albinoni's adagio playing in the background? [If so, I've plenty of those to share..... one day perhaps!!]

    C250 TD 1998 heavy black smoke after seal change fuel pump pressure valves

    In this thread, http://www.mbclub.co.uk/forums/engine/55297-delivery-valve-seal-tricky.html There's an extremely helpful post by compress ignite where the exploded diagram of the delivery valve is shown. The lower face of part 7g is a very finely lapped flat surface, and this mates and seals...

    C250 TD 1998 heavy black smoke after seal change fuel pump pressure valves

    Although it's crude, at least it's quick & cheap! I found it on a Bedford CF diesel engine I was working on - for some reason, I cranked the engine over without the fuel pipes on, and a spray of fuel was pushed back out one injector by the compression. I removed and pop tested the injector -...

    C250 TD 1998 heavy black smoke after seal change fuel pump pressure valves

    A quick way to check for an injector being stuck open is; - run the engine - stop it - take the injector metal feed pipes off, but, don't clean or blow the fuel out of the injector tops - ask an assistant to crank the engine while you watch. - if any fuel blows back out of the injector top, it...

    W124 0m606 flywheel sensor

    In document 07.1-2005, for the OM606-910 engine, the sensor (L3) is described as "starter ring gear speed sensor". If you do need to swap ring gears, you may also need to swap the starter motor pinion too.

    W124 0m606 flywheel sensor

    No, but, the EGR, the idle speed control, and perhaps resonance flaps in the inlet manifol don't need crankshaft position to be sensed, only crankshaft speed - counting flywheel teeth can provide this.

    Boing!

    Looking at the end of the spring, it wouldn't surprise me to find that this wasn't the first time this spring had snapped. However, it is best to fit MB springs, as they will be better tailored to the mass of your individual car. MB springs are graded using a points sytem based upon the engine...

    W124 rear wheel bearings

    As I mentioned above, ask the garage to check the outer diameter of the drive flanges carefully. If they're damaged (and they might be if there's so much play), then, you'll never get the bearings to run properly - there will always be play.

    W124 rear wheel bearings

    If they're so bad, don't be surprised to find the drive flanges are damaged on their outer diameters. It may be better to see if you can buy good S/H hubs.

    W124 rear wheel bearings

    As per Graeme's post, this really isn't a job to attempt to DIY. The bearing is fitted very tightly, more so on the estate versions than on the saloons. Attempts to remove the bearing without a hydraulic press and a good selection of drifts and supports will be futile. However, removing the...

    fuel economy of larger diesel engines

    The "road load" verification is described in here; http://www.unece.org/fileadmin/DAM/trans/main/wp29/wp29regs/r083r4e.pdf Appendix 4a - Appendix 1 describes dynamometer requirements In short, as stated above, aerodynamic drag IS included. There's no technical problem in collecting exhaust...

    e300td lift pump

    >>is that i think the tank isnt breathing, No, it's normal. If your tank really were not venting properly, it would collapse. Clean the strainers, fit the O rings, and fill the secondary filter with clean diesel when you change it, buy your fuel from the petrol station, and not the chippy...

    e300td lift pump

    If you fitted the new fuel filter dry, then, it will take ages to fill when you're cranking the engine over. If this is the case, there's possibly nothing wrong at all. If you haven't done this already, then, I would suggest renewing all of the O ring seals in the low pressure fuel system -...
