[diesel_mercedes] Lowering Compression

 

Only by removing the injectors or glow plugs and that's not going to help when you're trying to prime it .

If priming the system is the intent, is there a way to lower the compression in cylinders? Bill in Oregon

[diesel_mercedes] Help bleeding fuel system after filter replacement

 

A couple of ways to approach this :

I like to position the engine to TDC as indicated on the crank pulley then crack the # 1 injector pipe right at the injector _one_ flat only , pump away until you're getting fuel weeping out with every pump stroke .

Remember : if the hand primer pump has a knurled edge , you must first unlock it by turning the handle counter clockwise until iot clicks slightly as you gently depress it whilst turning , DO NOT forget to re lock it after you've pumped ! .

Then , hold the throttle to the floor and crank it until it not only runs but begins to overspeed the starter , let off the key but HOLD that throttle down until it clears out and begins to roar .

I assume you remembered to fill the new (spin on) filter with your choice of Diesel fuel or <magic>Go-Go Juice before installing it ? .

Hey guys,

After completing the diesel purge on my 83 240D, I can't seem to get the fuel system bled. I cracked the outlet line from the main filter to the IP and got fuel out. Cracked the other end of the line (input) line at the IP and got fuel out. I've loosened the injector lines and cranked in 20 second bursts and haven't gotten anything at the injector lines. Cranked so much the battery needed a recharge.

Am I missing a trick or do I need to just keep cranking?

Thanks!

[diesel_mercedes] Re: 300D car vibrates at idle

 

WELCOME NEWBIE ! .

First things first , it needs periodic valve adjustment else it'll shake like a paint mixed .

if it's really oily under the hood the motor mounts may well be shot too as Diesel contaminated oil attacked rubber and plastic fast , this is why it's so important to keep after the oil weeps & seeps and always shampoo your engine a couple times a year .

You're going to need some bent 14 MM open end wrenches to affect the valve adjustment , a new rockerbox gasket too .

Just getting familiar with the mercedes and have had no other experience with them.A new to me 84 300D vibrates very loudly at idle.
It is so noticeable that the sunroof is making a loud hum.
I just got the car started this weekend. Owner had said the trans quit working and had lost the ign key.
I picked up a key and ign at the junk yard and added some trans fluid since it was about 1.5 quart low.
car seems it will drive fine now but have only drove it in the yard so far.
when it is at idle there vibration all over the car so anything that will make a noise or hum does so.
Rev the car up and the hum goes away.
It is possible I just need to idle the car up.
It kind of reminds me of the vibration I felt in a TR6 I had when driving and it turned out to the a drive shaft to rearend U joint.
But with the 300D the vibration is at idle in park.
Has any one seen this before?

I have not checked motor mounts nor have I checked transmission mounts.

I remember forgetting to fill the primary (big) filter once after installing a new one. That was the last time I will ever do that. Almost wore the battery down trying to get it to start.
