Installing Delivery Valves

[Dave Remillard]

I did a search to find more information on installing delivery valves, but wasn't able to find the answers I'm looking for. I will be doing an install soon using the proper socket that is being offered by Piers. I would like to know approximately how much time this should take. I realize it depends on the individual, but keep in mind it will be a first for me and I tend to be very cautious when taking on a project that I haven't done before. I'm also wondering if there are any little tricks that any of you have or any precautions I need to take note of. I didn't ask Piers if there is an instruction sheet that comes with the valves. I can only assume there is. Perhaps the factory repair manual has good step by step instructions also. Thanks

I haven't done this myself, but I watched a Bosch tech swap a couple of mine. Once you remove the valve holder keep the area real clean. The next destination for any contamination is your injectors (nozzles). The tech used a lot of brake cleaner to flush things out. And pay attention to shims. Don't loose any! Other than that, it was pretty simple.

You'll need to remove your fuel lines. Your intake.



You may need 6 new steel sealing washer's depending on your model year.



You need the delivery valve socket, it can be ordered from Snap On ala carte.



Reference the Cummins service or FSM for torquing instructions and clenliness is next to godliness here. I'd use contact cleaner, that's nicer to the engine paint.



Finally when you are done you could blast the top of the pump, with the Cummins engine paint for a professional appearance.



Say maybe a half a day, if you really take your time.



Good luck,

I took my time cause like you, I didn't want to do it over. I think 3 to 4 hours for a first timer that goes slow and takes their time. Good instructions come with the kit I got from Piers. A nice easy job to do as everything is easy to get to. You will need a good torque wrench.

dont forget to soak the new ones in clean diesel fuel for a bit

just a good practice to give the lube a head start for the new valves

Soak them in fuel? There is a bit of fuel left in the pump area where the D-Valves drop back into. I would imagine soaking them would have very little affect. Just my opinion.



As far as the install, Piers instructions are excellent. For the extra careful first timer, I'd say 4 hours should do it. I have done it a couple times now, and the last time it took me less than 2 hours.



The only tip I have has been already mentioned, be very careful when pulling the barell to not let anything fall out.



Good luck,

I have a tip too... .



Get all that #@$%! waxy junk off the DV's before you even start the job. Do it while in the 'study'..... I bet at least 1/2 hour can be spent getting all that stuff off the DV's... ...

good thought Matt, but i dont have a "study" I have a room i call my library, but its not condusive to parts cleaning in there although it has plenty of plumbing and ventilation



are you thinking the wax is a bad thing, if left on. I was planning to do DV's in a few weeks. I'm glad you pointed that out.

 

[HoleshotHolset]

You'd be hard pressed to even get 'em into the pump if you left the wax on... .

uh Cooker..

Just another reason why i soak em in clean fuel.

Does the wax come off easier after you soak them?

 

[HoleshotHolset]

Try putting all 6 DV's in a bowl... . then fill to the top with #2. The wax isn't all that nasty... . but it's time consuming to take it all off manually without any pre-treatment.



#2 should help to eat that stuff off there... .

Just cut the wax on the side with a knife then it just peels of. The DV are coated with oil so the wax is not stuck directly to them.

A knife is handy once you pull out that little wire that is supposed to be there to "help" you get the wax off.....



Matt

 

[BigYellowIron]

I thought that the wire was used to dip them in the wax?



I dunno though!



Adam

 

[HoleshotHolset]

I just assumed that the wire was there to help you take the wax off... . or knowing Bosch it serves two purposes: To dip 'em in the wax... AND to help the end installer get the stuff off... .
