Good morning Bob. I have found that if you do hinges and pins or bolts that you need offset hinges for the pins to clear the frame. It is easier to use a couple of pieces of angle iron as a bed frame and drill a couple holes for bolts before welding in for alignment. If you are installing by yourself a floor jack and longer than needed bolts will get it started then shorter bolts for final install. It can get tricky with pins trying to align by yourself especially with new rubber supports. It does help to loosen the 4 top plate bolts in frame but leave installed.

Can the radiator frame be cut with a small air cut off grinder. And not damage the radiator tanks? Then put some pull pin hinges in a the cut for install? Bob Dunahugh

Bob,
Talk about a "Yee-Hah", we did that with Nick Chapkis's coach last year. I didn't a satisfactory air tool, so we (I - offered to let Nick and he declined) made the cut with a Sawzall - Very Carefully.
We put the stainless hinges only about 8" up from the turn in the bottom of the frame. Far and away, the worst part, (excluding the nervousness sawing the frame) was get the upper coolant and four cooler lines loose. Apart from those mentioned, getting the radiator itself out and back in was not difficult.

For those that cannot weld once the radiator is dropped, one can use bolts to the angle iron and make it work

Bob - I removed the bottom of the frame >carefully, with a cutoff wheel, and put hinges on each side of the 23'. If you have time an patience, unhook all the hoses (6 of them) and unbolt the bottom half of the frame at the top. Drop it and the radiator. Set the radiator aside, and then drill and bolt a hinge on each side centered front to back and such that the bottom of the hinge as above the curve of the housing. Remove the hinges and cut the housing between the bolt hols. Reattach the hinges and drive the pins out. Bolt each part of the housing back in place. Now all you have to do is stuff the radiator back (don't forget the cushions!) in place, put the bottom under, and drive the hinge pins in to hold it. Some folks replace the pins with bolts and nuts, I haven't seen the need.
I haven';t doe the 26' because when it fell it hit on the radiator frame. I straightened it with a sledge... but there's stress on it yet so I didn't cut it. If I have to remove the radiator again I'll try to find another bracket bottom off a parts coach. The current radiator is a recore from a year ago, it may not need removing in my lifetime. I hope.

I really don’t find it all that hard to raise the front of the GMC and drop the radiator out without cutting the frame.
We did Ken Burton’s at a GMCMI rally in Delaware and I recently (in Jan) replaced my radiator by just unbolting it and dropping it out the bottom.
It didn’t seem very hard and probably was a lot less work than cutting the frame and welding in hinge pieces.
Larry says he has had his radiator out “several times” since 2004. I have had mine out only once since I have owned it (37 years) and hopefully will never have to take it out again.

When you already have the radiator and support frame removed from the coach
is the best time to modify the support frame. Personally, I prefer two
pieces of 1" × 1" angle iron bolted together rather than loose pin hinges.
The angle iron bolts together, and each piece is welded to the support
frame on either side of the saw cut. That way, the nuts can point towards
the ground, easily accessible. I usually tack weld the bolts to the top
angle iron, it then can guide the lower piece into position during
reassembly, and you only have to handle the nuts and washers.
But, to defend Emery and Todd, how often are you going to be taking
the radiator in and out? Couple of extra pumps on the jack, and the whole
thing comes out. It is a heavy sucker, though. Use a floor jack.

I have had mine out twice. The first time Emery and Colonel Ken plus more than a few other observers helped at the Harrington rally. We called is a seminar because we weren't suppose to work on coaches there. The second time more than a few GMCers lead by Rob Mueller stopped by my hangar on the way to Amana Colonies and did it. I left town for a had to go trip to Cincinnati while the GMCers took care of my problem. When I got back it was done. We had GMcers from Indiana, Michigan, Ohio, Ontario, and Australia there helping. Several others later said they would have stopped by but thought there would not be a place to park when they got there.
Neither time did we bother to cut the frame. Both times I said why bother I'll never be doing this again and it was not a bad job without it.
As a side note, the second time we pulled it, there was a mis-diagnosis of the problem on my part and it did not really need to come out.
It was amazing how many GMCers helped out both times.

I'll add a point to ponder on JimH's technique, learned from working feedlines on tall towers. Run the bolts through the angle with the nuts and washers on top. Now, should one loosen and the nut come off, there will be a hole which you'll see from above when you're checking the oil and coolant. If the bolt points down, you won't see a missing nut from the top when checking. Hopefully, seeing the hole will keep Bad Things from happening. This alignment lets you also check every bolt on a tower from the ground with a telescope.

So, bolts in from the bottom? You make a valid point, Johnny. I guess, it
should not make any difference in clamping. Should help on the visual
checks.

Hmmmpf -- use Captive nuts on the top so you don't have to try to put two
hands where only one will fit -- like on my split fan shroud. :-)
(You can still use a telescope.)

Any time you use stainless fasteners be sure to use anti seize compound. The stainless has a characteristic of 'cold welding' itself together. Most noticeable when the connection is stainless to stainless, but also there with stainless to aluminum. Also, stainless hardware is MUCH weaker than the same size steel fastener. Rick Shoop
