Seating injectors

[yzmatt]

Can someone please explain to me what seating the injectors involve? I bought the tool that ford says to use, OTC 6067, because I don't feel real comfortable hitting the injector solenoids with a mallet. All I can see is the mallet might help compress the copper oring on the nozzle. But doesn't the torque of the bolt actually do that. So when someone says to hit the injectors with the mallet is it just to get it past the humps in the head?

So is there an argument to not using Fords recommended tool and hitting the injectors? If just for the copper oring have a hard time believing that hitting it will compress it.

I've always tapped, not hit, with a dead blow , till you can HEAR it seat , I tq them, then tap them all again. After that one more tq then I check with a straight edge. I don't see the need for any special tool

wtf?

do you guys lack testicular fortitude to put them in by hand????

push it down, catch the boat on the anchor stud, and either hit the opposite side of the boat with a hammer or push it down with a pry bar.... I have never had to hit the solenoid to seat the injector....

Learned a new quote. Testicular fortitude. Anyways its for the last two on the passenger side bank, and the one back on the drivers. Other wise I do push them in but I had issues a while back and two friendly gentlemen told me I didn't seat the injectors correctly, because I didn't hit them.

So it is just to get the injectors to compress the orings to get past the humps.

let me guess, you were tossing fuel out the exhaust and a choppy idle, if it ran at all...

so your injectors probably looked like this...

this particular one was due to the fact the guy felt the need to hit the injector with a hammer.. knocking the copper off and crunching it...

do like i said, push them in as far as you can, than make the boat catch the stud, you may have to hold the boat onto the stud, but then push down on th eopposite side. injector will slide right in.... than torque it...


what torque did you go with the first time??? You can also use a straight edge and lay it across all 4 injectors to make sure they are seated...

Don't understand the problem with hitting them with a mallet. Tap, tap, thunk. Injector seated.

LOL... Some people.

Lube the injector body, stick them in the hole, tap them down by hand and a light tap with a dead blow and your done.

If you want to buy a special tool then by all means do, but your not going to hurt a damn thing by giving them a nice tap.

Dont feel comfortable with it why?

So you hit the injector too hard huh?? LOL. It's ok. Don't have to blame someone else JK


I hit them as well. Done many injectors. In fact the whole dealer does. I don't know of any who doesn't hit them with a small mallet.

You can set then by hand all you want. I like the security of knowing, and checking twice by tapping then re tqing. Sorry, pulling everything back out because it wasn't right the first time doenst sound like fun to me

Just tap it in, just tap in, lets do a little tap, tap a roo. LOL.

 

[DEEZUZ]

no it definitely was someone at our shop though... I asked how he got the injectors in there, reached into his box and pulled out a catawampus mallet...

he was mad cause he hates in general and I was the one who discovered the issue he caused.

you can have your 'security' of knowing they are seated all you want, but if you do it the right way the first time there is no need to recheck or double tap anything.

most of the times i dont even have to hit the boat with a hammer, i just press my thumb down and injector shoots right in

That's certainly your choice. But nothing pisses me off more than getting all the way done, ready to test drive and having to tear it down again. Sheet happens . You can eliminate that by being thorough god forbid you lose a whole 2 minutes

Boat or bolt???

 

[DEEZUZ]

the boat... technical name injector hold down. i call it the boat

 

[DEEZUZ]

let me ask you guys this just for clarification.. you guys are only removing the hold down bolt right? the outboard bolt, not the anchored stud towards intake...

 

[Alfie]

I only remove the outward bolt closer to exhaust manifold but you can remove the other bolt. As it has a shoulder and will stop. I just do the one just cause I'm lazy. Less work is king. As I always look for a way to do less.

Shoot. On 6.4 t stat I just remove the upper hose and fish them out. Do the whole job in like 20-40 min. Depending on my mood that day.

lol, is there any other way to do them stats besides that? lol


the only case in which I have removed the anchor bolt in a 7.3 is for #3 in an E-series. in that case the solenoid comes off too... but its an anchor bolt, use it as it was inteded, so slide the injector down by using the hold down(boat)

 

[CSIPSD]

Tap Tap... Ting... You know its done when you hear that "ting"...

 

[Alfie]

Believe it or not. I have never worked on a 7.3 van well for injector replacement I have done harnesses but never an injector. . Just 6.0 vans. Once my help installed a set of injectors on a 6.0 van. Don't know how many but I went on a road test as he left early. My dumb ass left my phone on my box and I broke down about 3 miles from the dealer. And this dealer was on the edge of town and I was in the fields. So I walked back like a dumb ass. Soo pissed off.

Oh it hydro lock with fuel. Haha. Good times. Can't say I haven't done that tho. Sucks it was a van tho.
