OPINION ON DIY INJECTORS FROM ROSEWOOD

I have heard some horror stories about diy injector kits. I have a buddy thats thinking he wants to do a set. Is it worth doing it yourself or is it better just to buy a set thats already sone and flow tested?

I have heard he has Good instructions , but a clean work area where you can find small dropped objects is a big part.

Should be fine unless you have 200K miles on the injectors which if that is the case, senfdthem in to be rebuilt by Jim or anyone else. In any case, they can be flowed on a bench test and checked for uniformity.

Re: OPINION ON DIY INJECTORS FROM ROSEWOOD

I've done Jim's kits on higher mileage trucks. the biggest concern(or hardest to do) is correcting poppet valve clearance's on the oil side, they tend to be more worn on higher mileage psd's. Its kinda a pain in the butt to have to take six or five or even eight injector bodies down to a machine shop to get the tolerances corrected while you have the rest of the injector parts laying on your bench itching to get lost. But it can be done, you just have to keep track of what parts go where(like marking injectors) and put them back.
Probably the best thing you could do is to get on Jim's site and follow the instructions on checking poppet valve clearance. If most of them are out of wack and your nervous about fixing them then you should send them off.
I think that has long as you have all the tolerances correct and a new set of nozzle's, they will probably be pretty balanced.

Re: OPINION ON DIY INJECTORS FROM ROSEWOOD

How does this all work out cost wise?

Building your own having possible machine shop cost, having to send them off to be flow bench tested. Versus buying ones done by people that know every little thing there is to know and you know they are balanced flow tested and tolerances are GTG.

What is the actual cost savings of doing it yourself versus buying them built? this is really a question I am asking cause I do not know.

238 80% hybrids are say $2300

How much is the kit?

How much to get them flow tested and make sure they are balanced?

How much would any machining cost if needed?

How long does a rebuild generally take for someone to do if nothing goes wrong and they have good mechanical skills but this is their first time doing this?

Funny, I haven't heard of any.
Worst thing I have seen is of the several hundred DIY Kits I sell every year, I usually have maybe 6 or 8 customers mess something up. Then they send them to me for repairs and usually end up paying what it would have cost to just have me do them in the first place. You don't really loose anything, unless you totally screw up machining something and have to replace an injector.

http://www.RosewoodDieselShop.com, check out the DIY Kits and Injectors pages for prices.
I'm not sure if I can post actual prices on my stuff, but I generally charge $200 over the cost of a DIY Kit to build the injector set, and that includes flow matching and a 1 year warranty. To some guys, it's not so much about the savings as it is doing something hands on yourself on your own truck.

My 238cc Hybrids with 100% over nozzles are no where near the price you quoted.

And new for 2010 I offer an Armature Shim Pack that almost completely eliminates the need for injector body machining. These shims go under the Armature Plates and lift the Armature Plate up restoring the tolerance under it. I have worked on so many injectors in '09 from the big reman shops that use these shims, I went and found a place to make them for me so I can offer an easy, affordable solution for the DIY'er.

Re: OPINION ON DIY INJECTORS FROM ROSEWOOD

For 200 more bucks Id rather send them in and have them flowed vs building them myself then sending them in to have them flowed.

All the DIY Kits for Split Shots for AB and AD are the same, and yes they are different. But the Kits do the same for each, whether it's a basic overhaul, nozzle upgrade or Single Shot conversion.
