Re: [diesel_mercedes] Start of Injection Adjustment

 

Here's how I have done it . . .

Pull the line to the #1 injector and turn the crank by hand a couple of times with the pedal at full throttle. This will fill the output spout with fuel but not spray it all over you. Then use a lint free towel or rag and blot up the fuel in the little spout until there is just a very little bit at the bottom of spout. The "spout" is a tiny funnel shaped affair and you just need to have the very bottom of it just barely wet with fuel. (I say "lint free" just to cover my butt. I usually just use the corner of a double folded t shirt.) Then watch it carefully as you turn the crank by hand with a long breaker bar type setup. You should see the level in the spout just start to change at 24.5 degrees BTDC.

But you needn't fear the dissassembly process either. And the "U" shaped tube can be made from a salvaged pressure pipe from another engine. Just bend it around a 14 mm socket and cut it off. Don't worry about flattening it - they are very thick walled.

Hope this helps,
Bogy.

[diesel_mercedes] Start of Injection Adjustment

 

Has any of this august group attempted to perform either of the beginning of injection adjustment procedures as described in the the manual? I am not comfortable with the low pressure method without hearing from anyone with experience as it entails some IP dissasembly, and the HP method requires special tools not readily available but again experience may provide some substiturions.

[diesel_mercedes] Re: seat slide & Auto Envy

 

Y'know while this guy was hinting about buying the car, I got this real sense of "its my car" just like it is part of my family or even part of myself. I mean ITS MY CAR some folks will say but its only iron, but its my iron-- oh crap not good to get attached to material things eh?

Re: [diesel_mercedes] Glow Plug Question

 

Do the valves. When my Used engine was hooked up, it took a good 30 minutes to get everything rolling along, and the puff (plume) of grey blue smoke was cheered by everyone. Did not need any further tweaking, but like a heart transplant it did need some kick starting after 6 months of downtime.

you betcha bippie.  This is a COMPRESSION IGNITION engine.  If the valves don't open at the proper time you don't get enough air in and if they don't close at the proper time you don't have enough compression to fire the engine.  Actually in this case its more whether they are sealing properly on the compression stroke than any minor lead or lag caused by bad clearances.  There is of course also the possibility that you have enough burned, warped or otherwise poor fitting valves that it won't start without a valve job.  Adjustment is the first step.  If that doesn't work check the compression.

[diesel_mercedes] Re: Glow Plug Question

 


Try watching the battery voltage as the glow plugs are cycling ~ if it drops below 11.2 VDC at the battery while they're heating , either the battery is low charge & needs a deep , _long_ charge at 10 Amperes or less , or the battery is Kaputi or maybe just the terminals are corroded .

I assume you kknw that pumping the throttle on a Diesel engine whilst cranking , will prevent it from starting .

RE: [diesel_mercedes] Glow Plug Question

 

10.7 volts seems a bit low.  However, 70 degree ambient temperature seems plenty high enough to start without the plugs.


How are the valve lash settings?  Does the car do anything while trying to start?  A pop or chug?  Any smoke from the tailpipe?

sound like weak battery To test battery have someone else turn ket to start check voltage. If bellow 11  volts you need a battery.

Thanks guys, it isn't raining today, so will get my head under the seat today. Nate I understand not letting people drool on my car, but I swear he was ready to pay me at least twice what I paid.
But then I would just have to find another 300D.
