Injector Lines - Steel Soldiers::Military Vehicles Supersite

Squirt-Truck · 11-20-2011, 19:38

So the IP has got to come off and go to the shop..... it leaks everywhere.
Does anyone have any suggestions for getting the injector lines loose at the IP head?
So far I have destroyed two wrenches (yes appropriate line wrenches) and have only two of the line nuts off.
They are currently soaking in kroil, but they are not dirty, rusty or such. All the weather caps were still in place. They are just .......tight.......

I am open to suggestions.

I faced the same issue with mine. I ended up removing all the lines from the injectors first. As I recall, I was able to get 3-6 lines off first and out of the way. That offered up enough room at the hyd. head to use my nice vice grip wrench on the offending nut. Kroil might help, but the lines/threads are designed to seal off the thread area. You might actually try tightening the nut slightly to "break loose" the rust.

Can you clamp a set of visegrips over the flare nut wrench? I have done this on other similar situations with success. Not sure if there is room for this though.

Is the IP junk? Can you apply direct heat?

If it helps,

I had a lot of good luck with flare nut crow's feet wrenches (craftsman brand). I was able to put a breaker bar on about 12 inches of extension on it.

I really thought I was going to break something, but it finally let go and loosened up.

I think the biggest help was being able to apply the torque where there was plenty of clearance for the breaker bar.

Good Luck!

I have an old open ended wrench that is much more stout than any flare nut wrenches or other open ended wrenches that never fails me. I can send it down if you like. PM an addy.

Mark might have to tap it with a hammer, but I have taken off MANY stuck lines with this one.

Mark,

I have had a few of those here,I did as patracy said, removed the line from the injector,then slipped the box end of a combination wrench over the line down to the IP end of the injector line.

This usually works,and you can always double wrench it this way if needed.
Hopefully your 5 ton has the later style fenders and not the early gasser fenders,either way,it's a lot easier with the power steering tank out of the way.

Squirt-Truck · 11-21-2011, 18:37

Well thanks for all the suggestions guys. I am hoping to avoid cutting the lines and going to a socket......
And yes.....it still has the gasser fenders that are bears to remove and that darned tank is VERY in the way.
Gimp, I also have one of the old open ends, I will give that another shot...

Wish me luck, 2 done 4 to go.....

What's leaking? HH or lower?

gimpyrobb · 11-21-2011, 19:45

If you can turn the wrench with all your might and it doesn't "open up" to round off the corners, tap it with a hammer 3-4 times(tap, not slam) it should free up just fine.
