Nope. When timing mine, there were no washers, seals, or gaskets to be replaced when I pulled #1 DV.

get a couple spare green o-rings from your Bosch shop for the delivery valve holders. You may tear one when screwing out the holder.

Agreed... ... . I keep spares in the glove box.

O-ring was smooth on mine so I left it alone. If I had replacements on hand, probably would have changed it. Did not and no problems so far.

Some DVs have a thin gasket down at the bottom. we always change the o-rings out on the DVs at work. o-rings and gaskets on the DVs vary from year to year, I'm not sure which years have what.

I agree, I would have the O-Rings on hand.

I was lucky to not to have to change mine out, but not saying you should not keep spares in the glove box, like Jim Said... Always good to keep spare parts!

Installing DV'S

Is there any certain torque value these delivery valves need to be torqued down to?

Wow Jim, that was a quick response

191 dv install

When reinstalling the dv holders, do i need to lube the threads on the dv holder before installing them into the pump? If so what do i need to use?

 

[WadePatton]

I didn't. Don't think you need too as they are brass.

 

[Joseph Donnelly]

Most folks just use diesel fuel as lube but a bit of grease is OK so long as you don't get a gob of it inside. The holder is cad plated steel, not brass.

Joe -



How do you know all this Cummins minutiae? Maybe a bookcase full of service and parts manuals, tech white papers, etc. in the throne room?

 

[WadePatton]

Wondered how they got the brass so hard.
