May have found the source of the shake (123 300D)
 

So my dads 85 300D has always shook, a lot. I posted about it a while ago, but lost interest in looking for it as other projects came up, and he drove the 240D daily this summer. As we are about to put the cars away for the winter in Ohio, we figured he ought to drive the 300D for a week or two get it some exercise before it gets put away again.

I had some new lemforder motor mounts, so I put those in. I have already checked for air leaks, replaced all the rubber hoses, diesel purged, replaced the filters, adjusted the valves, and installed the updated primer pump. I was out of ideas, and the mounts on the car were obviously collapsed.

Put in the new mounts, and it entered a whole new world of shaking, it's incredible how much it shakes.

So I started cracking injectors, 2-5 all make it even worse. With cylinder 1 cracked, the motor runs smoother, not firing cylinder 1. Tighten the line back up, goes back to shaking like all hell.

Moved injector 1 to cylinder 2, and 2 to 1. Same situation runs better with 2-5 hooked up and 1 unhooked. So that points to the IP.

I'd heard of stuck delivery valves, so I popped out the cylinder #1 DV and found...

That's all permatex that I dug out of the threads and out of the different pieces of the delivery valve. The bottom part of the DV was totally stuck in the chamber, used some smooth plastic tools to jiggle it out and dug out even more permatex.

The stupid things people do never ceases to amaze. Ordered new copper crush washers from the dealer today for $.85, hopefully this makes a dramatic improvement now that #1 DV isn't glued in place halfway up.

Why'd you order those expensive washers?

Well dealer called back 000-074-17-59

is actually NLA, so duct tape is becoming a possibility.

Try a Bosch fuel injection shop for the washers.

Yikes

Did you ever find the washers?

I had no luck with the dealer; parts no longer available from MB.
No Bosch Shop in Tampa; called Bosch, they referred me to a bankrupt closed shop in Lakeland Fl.

Did have luck with ADF Diesel Montreal Inc

Took a week to arrive from Canada at .96 each.
Received them today via regular mail with no shipping charge.

Hope this helps

Beautiful!

Please let me know if the shaking disappears, mine is extremely annoying.

Masc do you have a part number for the Canadian company? I will call tomorrow.

This site is a parts interchange site but you need to be carful with it. I think has the Bosch Number

Car Part MERCEDES 000 074 17 59 (0000741759), Seal, injector

1 410 105 020 for the Bosch I will try to verify that if I can.

See post #47 It had the Mercedes and the Bosch part number for the Crush Washer

1410105020 is the correct part number. (Thanks to Cho from previous postings)

They are indeed the correct washers.

Last time I found delivery valve crush washers, I had to order them from a Bosch shop. They were a few bucks a piece. They are not easy to source online.

I have noticed a lot of delivery valve problems lately and often causing a shaking condition. I experienced this myself with my newer 300SD not long ago. I wound up replacing all 5 DVs after a lot of troubleshooting and like magic, the shaking went away.

I thought that Frypower also sold the Washers?
