Injector nozzles

***99cumminsho*** · 10-06-2007, 11:35 AM

Im ordering a set of 100hp jammer nozzles and i've been reading that i need to have them pop off tested what exactly is that is it just a pressure test or is it more complicated than that? Im very mechanically inclined would it be simple for me to change out the nozzles myself?

its a machine u put the injectors in and push a type of liquid through to get the pop off pressure on the guage, pretty simple

so its safe to say that i have to get'em tested? How difficult is it to change nozzles?

I got a new vp coming from Gus at Farm Boys Diesel along with a set of 100 hp jammers. He said it is fairly simple to do. My buddy, CTD mechanic, is coming to help me do the vp install and injectors next weekend. Keep you posted on the easiness... ( vp is for the second time around so that will go fairly fast

So you can pop test your injectors at home?

injector swap is easy

you need the equipment to pop test them

Well i would have them pop tested by someone but i'm able to do everything else.

Swapping out injectors is an easy job. Time consuming, but, easy...

do believe they are the shim kind, more than a 2 min job, i have a poptester do lucas/cav all the time, the bosch unit need a fixture to mount them in.

this might help Injector Tool ??????????? - TDR Roundtable

You don't need no special tool, all you have to do is use one of the intake horn bolts. It'll just screw right into the top of the injector and use some vise grips and a pry bar. Give it a little pry and it'll pop right out, very easy. Also you might want to call around and see who can pop test them, around here in colorado, no one would do it for less that 150 bucks. Which is just outragous. I didn't get mine tested, I just tightened mine down as tight as they were when I took them out. They're running like champs, but I would still recommend getting them tested, I'm just waiting to talk to the right person to do mine for free, then I'll rip them out and just double check. Hope this helps.
