T-bolt clamp removal

I still need to go back to my last post and respond to the questions about my CAC failure due to damage from loose cover.
In the meantime, I'm about complete removing the CAC to get it repaired or replaced.
Right now I'm stuck at getting the hoses free so I can pull the cooler out. Holding the tubes to the inlet and outlet are spring tensioned t-bolt clamps. I've got the springs untensioned but can't seem to get the clamps loose.
What's the secret/tip/trick?

Take the nut completely off. That should give you enough "expansion room" to slide the clamp out of the way.

that did the trick. Now to try and pry the hoses off. Is it possible to have any less room back there?

well! After struggling for half a day to pry the flex hoses off the CAC header ... I've made not a millimeters progress. So ... since there's zero room to work from the ground up, I finally gave in and unbolted the access plate inside.
There's a metric ton of t-bolts holding the flex and steel hoses together, but it appears to me as though the only way I'm going to get anywhere is to use the only two short connections - inlet and outlet at the turbo, and then remove the flex hose from the CAC once I remove it and the connected piping?
is there a better way?

I think you answered your own question

You could cut the hoses off, I assume you'll be replacing them anyway when you replace the CAC. New hoses should be a lot more flexible to install.

Actually, I found it easiest to work from inside the coach ... pryed both intake and return hoses off the engine.
BUT ... then I got confounded because the fan shroud didn't give me enough room to pull the CAC out. Tried every position variation to find enough give to wiggle it out but no joy.
So ... I figured I would just unbolt the shroud, since the top of it was already unbolted. That way I can move it Round the fan shaft to get all the space I needed.
Of course, plans never survive the first contact with the enemy. So far 1 broken bolt, 3 rounded, frozen, very small bolts. They're hidden away well so extremely hard to get to and a weird size. The broken bolt has a 3/8 head. The bolt on the opposite corner rounded immediately with the 3/8 socket ... 11/32 seemed a better fit. The 2 middle bolts appear to be more like 5/16.
So far bolt extractors failed, vice grips failed, penetrating oil hasn't helped. Can't use heat with the plastic shroud.
I figured my next step, assuming I'd be able to line it up enough to get some action going, was an impact screwdriver ... so I used the dremel to cut a groove in the head of the corner bolt. And then discovered that my impact screwdriver kit was missing the bit holder. Sighl
Heading into town to get another kit.

no room for the impact driver.
I guess my final solution is to get the Dremel in action and cut the bolt heads off, and drill new holes for self tapping screws when I replace the CAC.
The heads are just too shallow for vice grips to bite, and too soft for bolt extractors to get a grip.

Have you been soaking these bolts with PB Blaster every day? Some here swear by using transmisison fluid and acetone mixture too.

If there’s anyway you can pry the lip of the hose up enough to spray WD-40 under it then wiggle the hose in an effort to spread the wd-40 around the inside of the hose. it seems to work for me

PB Blaster did nothing ... usually more success with Liquid Wrench which I've used over the past 4 days to the tune of 1/2 can. No joy.

Took 3 hours yesterday to dremel/grind off 2 of the bolt heads. Need to get some more grinding discs this morning to get that last one off.

Can't say that working under the back of the coach on a gravel driveway is my favorite activity. Getting to old for this fun

PeteandDeb, I really feel for you. I have suffered similar circumstances back when I farmed, only I was working on cold wet dirt, and when I owned semi's. Then it was cold wet slush.

Perhaps, this is why most truck repair shops want nothing to do with rv's.

Get set of these to get the hose loose from the tubes.
Are you sure the bolts aren't metric. It sounds like when you say the standard sockets don't fit.
Also I have that using a large piece of cardboard on the gravel helps.

yep ... using cardboard on the ground since there's not enough room for me and a creeper. Still feel the rocks thru the cardboard and clothing.

The problem with the hooks you posted are that they require me to be on the other side of the CAC ... and I ain't. Managed to remove one hose with a tjin prybar but zero room on the other side ... which is why I'm trying to free the fan shroud - to get enough room to wiggle/pry the road rside of the CAC out ... the curb side is free.

Progress: 3 bolt heads cut and/or ground off ... shroud is free. The problem with not being able to use sockets or extractors was the head design. Very flat design and slightly beveled ... so no surface to get a bite. I'm guessing the engineers figured once the shroud was in place, no sane person would ever want to remove it. One bolt seemed to fit a 9mm socket, another seemed to fit a 5/16 better and the 2 outside bolts seemed to like 3/8 sockets ... but none fit well enough to turn without rounding (and, yes, only quality 6 point sockets used)

burned out with too many muscle aches to finish (or trying) removing the cooler today; fingers crossed that tomorrow is the day.
