Has any one ever replaced theses injectors sleeve? Is this a big job? is this done with injector replacement? Getting fuel in coolant 2002 7.3 one ton. Thanks Den

 

Its much easier with the heads removed. There is a "slide hammer" tool that threads into the old cups, and pops them out. Then pound the new cups into place. The cups are relatively inexpensive, but the labor isn't. You could try and pressurize the coolant system with the injs removed and see if one is leaking, or pull both heads and do it on the bench.

Ford tool numbers are as follows
removal kit
303-DS105 old number D94T9000B
Install tool
303-D109 old number D94T9000C

 

Brian is there any pattern to why those cups give up? Overheating from a coolant leak or anything you can put your finger on?

 

We have seen some older broken cores, newer trucks, but its hard to pressure test them, so now we change them out as a standard practice on each new build.

As for the root cause, we aren't sure.

 

Ok, thanks.
Sounds like a crap shoot then. Most of them are good but once in a while...........

 

I have done it and its actually not that bad. I was lucky enough to have a buddy who works for a dealership snag the sleeve tool its just a big tap with a sleeve that keeps it strait in the injector sleeve. If you can find the tool its not hard its just an 8 to 9 hour job. And as far a pressure testing them, your better off replacing all eight.

 

In my area, I had trouble even finding a shop with the tool. One shop said they would buy the tool if they had to do the work for me. There is an install tool as well .I went to a ford dealer to have a look then built my own tools. Like WonderDoney said, cheap parts and a lot of hours.

 

You need a puller i have seen people use a body puller and thread in through the bottom of the cup. Then you need to use a tool or an old bad injector to pound the new sleeves in. Just some tips drain the coolent before you pull the sleeves or you will fill the cylinder up, you will get some coolent and oil in the cylinder so you will want to pull all the glow plugs seat the injectors and then manually crank the engine and watch your eyes.
