I did this job in cab last year. I bought a super cheap injector cup puller and installer on eBay…worked great!

I'm convinced you don't need a fancy, expensive tool to do this job. They do make it easier when you have the remover, and something to press it in.

Hey guy, really nice video and explanations. I dont even have a 7.3 (YET), but between watching you and that Cox fella I'm pretty sure I could successfully replace/upgrade some injectors and cups. Thanks for the great content.

The safe way to avoid hydro lock is when the glow plugs are removed, replace the valve covers with a couple bolts, then hand crank the engine several revolutions by the main shaft. Important to put the valve covers back on or it will spray oil everywhere!
@mygarage.3 жыл бұрын
Very good advice! I cranked it over by hand with the glow plugs and injectors out.... It got the fluid out of the cylinders but pushed some back into the cups. I also strongly recommend putting the valve cover back on. I just covered the holes with rags and ended up spraying my work bench!! 🤣 had to edit that out of the video. 😏

@@mygarage. Just costs "8 sense" to pull cups .. lol 😂 ... I DO thread cut all the way to the bottom, and then back off 1/2 turn... because it is possible to try to pull a cracked cup (and a lot of them Crack just above the first bevel at the weak point) and have the cup separate during the pull... Bottoming out, seals the penny to the bottom of the cup further protecting the hole from shavings falling on in. And reinstalling rule#1 ... CLEAN, CLEAN, CLEAN, CLEAN, CLEAN ...

What keeps bristles from the wire brush out of the cylinder when you clean out the heads?

That's a good question. I was using a new brass brush, much softer bristles than the steel wire ones if they do fall into the cylinder.

When you clean where the injector cup sits what stops the debris from falling in?
@mygarage.3 жыл бұрын
Once you get the cup out, there isn't much left in the bore. I used a cylindrical wire brush and sprayed it down with brake parts cleaner. Nothing big goes into the cylinder.

Im just replacing my injector seals do i have to pull the cup out? And i dont have the tools to move the shaft to pump oil out of the pistons! Can i just put injectors back in and just crank it a few times, i had oil in my fuel so asking how they drained those, i just put new oil in b4 the seals went bad,
@mygarage.8 ай бұрын
You don't have to pull the cup out to do injectors. I would recommend installing the injectors, removing the glow plugs and crank the engine over.... It's going to make a big mess, but you will need to get the oil and fuel out of the cylinder or else you will hydro-lock it.

So if someone didn’t drain the coolant before pulling the cups out -like you specifically warned against- and the coolant went into the engine, what would be the appropriate next steps to take?
@mygarage.2 жыл бұрын
I would drain the coolant, and the engine oil, pull the glow plugs out, and replace the injector cups. Then install the injectors, then roll the engine over by hand to "pump" the Coolant and oil out of the cylinders, re install the glow plugs, add oil and coolant, and fire it off.

Hi i have engine 7.3 1996. but i have a problem. Frecuently be mix oil with diesel and change new orings and works again by some time. do you think that my cup is broken or need replace?
@mygarage. Жыл бұрын
Usually a crack in the injector cup will put fuel into the coolant. Oil and fuel mix has to be within the injector, or oring, possibly the fuel pump failed and it's leaking from the pump pushrod.

How do you clean the injector bore hole before putting in the new injectors without pushing a bunch of debris down the hole?
@mygarage.2 жыл бұрын
If you get the injector cup out without getting coolant, oil and fuel in the cylinder, there isn't much debris to worry about. I used a cylindrical wire brush on a slow speed drill. Basically like a shot gun barrel brush. Not really any debris was in the bore. Sprayed with a small amount of brake clean, and blew it out with compressed air.

@@mygarage. Dang, I found a good article with dummy proof photos so I figured it out. I have the injector bore brush but my loc tite was rock hard lol.

@jeremybarbieri51503 жыл бұрын
Yeah, its normal to have it fill with fuel, and oil. You HAVE to drain the coolant too or else all that will go into the cylinder also. Having fluid go into a cylinder isn't a big deal, you just need to crank the engine over with the injector or glow plug out so you don't hydro lock it.

I am not sure. The Engine serial number was a 98 production. So obviously was not original to the donor truck (it was a 97) the donor has 324k on the clock, but the engine looked relatively clean inside, and had even compression between 375psi and 400psi (Measured cold @ 6,000 ft elevation) I know it wasn't the correct way of checking compression, I was only looking for good even numbers.
