Hey! New guy to the site and loving what I see so far! I was just wondering if it would be possible for me to fab up an injector puller. I was going to fab up a piece to go on my slide hammer I have. The only holdup is I am unsure of the threadcount/size of the injector where the fuel line is screwed on. Anyone able to help?

 

You just use the bolts out of the heater block that you have to pull to get to the injectors anyway and screw them into the injectors, and now you have your injector puller.

 

if it is a 12v a lug nut off your truck and a 1 3/8 tall piece of 3/4 pipe will draw them out nicely

 

on a 24v just use the valve cover bolts they already have a slide hammer on them too

 

Another trick for a 12V - please specify what truck you are taking about:

"From a TDR posting - To remove 12V injectors, you can make this simple puller created by TDR member "Koa Man".

Buy a metric bolt 14X1.5 thread, between 4 to 4.5 inches long.
Do not use a bolt longer than 4.5 inches - it will be too long fo fit under the cowl on the last two cylinders..

Get the longest nut for that thread you can find. The longest one I was able to get was only 7/16 inch but it worked.

Get a big nut that will slide up and down the bolt but not go past the hex head for a slide weight. I used a 3/4 inch drive socket for mine.

Thread the nut on to the end of the old injector and the bolt. Use your little slide weight and after a few whacks the old injector comes loose. (I got this little trick from Joe D, who also supplied me the 370s)

The metric bolt and nut was hard to find here, had to go to a company that only sells nuts and bolts to find it. Home Depot, True Value, etc. did not have it. It was also expensive, $11 but I needed it now. In hind sight, I have a cheaper way. Just by the 14x1.5 metric nut. Get a SAE bolt (they are cheap) that will almost thread in and force it to jam the threads part way (make sure you have your slide weight on first) or you could braze or weld it on. Then you can thread the other end of the metric nut on to the injector. If you use a 3/4 in. drive socket like I did, make sure the socket end is facing down to clear on the last two cylinders. You will also love the 370s, big increase in power ALL over. No hesitation or infamous 1100 stumble in my truck. Joe D told me my 180hp pump should work just fine and he was right. I adjusted valves, changed injectors and AFC spring, all for the first time, including bringing out tools and clean up in under eight hours, which included my neighbor coming over and asking questions for half hour. and another half hour lunch break.

I've used a number of things from slide hammers to pullers to nuts and a big crow bar of all things and depending on how long they have been in there they all come out with the right motivation. Again, depends on the truck.

 

it all depends on what injectors ur trying to remove (12v, 24v, or CR) . using a slide hammer would be har to do, since u cant get a good angel on injectors 5 and 6. good luck

 

alls i did was weld a bit of rnd bar to a bolt to form a handle and pulled the injector out. didn't take a lot of effort. but 5 and 6 were hard to get the right leverage on.
