Leaky delivery valve on your OM617? Easy fix! Follow along with this video and replace those leaky crush washers!
Side quest: My OM617 has had a little shake right off idle, and I've tried replacing the injector nozzles, adjusting the valves all to no avail.
We inspect the old delivery valves and discover they are stuck, so I put a different set in and find the car is drastically smoother.
The crush washers are part number 0049974540, or Bosch 1-410-105-021

Pretty cool I’ll have to take a look at mine are you able to buy those components brand new ? You said you picked up a use set

@trythistv Жыл бұрын

I've not found brand new DVs anywhere, A bosch pump shop might be able to source them, but I wouldn't bet on it. at least the crush washers are still available.

congratulations for the work. I haven't really seen a delivery valve video on the web. I know that the injectors work with 140 bar. what would be the ideal pressure that delivers these injection pump valves? obs. the platform is not warning about your videos. hug from Brazil

@trythistv 11 ай бұрын

I hadn't seen much of anything about them either, the main purpose of these is to keep fuel flowing in the correct direction and cut the fuel delivery at the right time. I'm not sure there is any kind of rating as far as pressures, my understanding of delivery valves is quite limited but modifying the shoulder (with high precision, very expensive tooling) would result in more fuel or different timing on the fuel delivery event, but the pressure would still ultimately depend on the injector shimming. Hopefully someone more knowledgeable can chime in if anyone else has insight into delivery valves function

Are you asking about the axle shafts themselves? I'm sorry I don't quite understand.

@AlexOnParkwood Жыл бұрын

Do you have any part numbers for the original delivery valves? I can attempt to source these from Germany and get a link for you.

@trythistv Жыл бұрын

I do! The Bosch part number should be 1 418 512 008 The Mercedes part number should be 000 074 51 84 I've found a few sites that claim to have them but they are sites I've never heard of that I hesitate to recommend just in case they are shady or something.

Where can I find some of these valves? Been looking everywhere

@trythistv Жыл бұрын

Finding them new is near impossible from everywhere I've searched. Used ones from a junkyard motor like I did or perhaps a bosch pump shop might have better connections.
