help with removing radiator on H

The radiator needs to be taken out on the H. It's been leaking for awhile. Having troubles. A horizontal steering rod goes through the top of the rad, but I can't pull the steering rod out either side of the rad because it just won't come out the front end and won't come out the back because there is a small rectangular metal piece on the rod at the other end (closest to steering wheel) that won't allow one of the mounting pieces to come off that end of the rod.

So the only way I can see being able to lift the rad up and out is to take apart all the steering components (the horizontal rod and the vertical rod that's headed down to the front tires) in one big piece. Am I right?

There has to be an easier way to do this? Any help here would be appreciated.

The steering shaft comes apart at the u-joint. Take the bolt out, then the forward section of the shaft will come out of the steering sector through the front of the bolster.

The steer shaft isn't hard to get out. You take the cap looking part off then with the coupler/u-joint unhooked you just sort of screw it out. Yes yopu may need a pipe wrench etc to do it but still not that bad

Take the bolt out, take the big cap off the top bolster. Then just turn the steering wheel one way or the other, it will push out the front.

The bolt on the bottom has coter keys in them, you should be able turn the nuts to brake the keys

On the steering shaft at the light bar post are 2 collars with set screws on them. Loose the 2 allen screws on the collar towards the front of the tractor and move it foward about 6 inches. Remove hood and grill. Loosen the bolt on the u joint that is in the steering shaft. You may need to use a sharp chisel to spread the knuckle a little. Take a hammer and blunt chisel and drive the u-joint off of the worm gear shaft. Lot's of penetrating oil and heat may be needed. This is a keyed shaft so don't try to rotate it to get it loose. Once this is separated remove the large cap that is located on the front top of the front bolster. This is what holds the worm gear shaft in place. Clean the shaft up as well as you can and use some oil to keep from damaging the seal in the front bolster. If you ding the shaft with the pipe wrench use a file to knock off the sharp edges before you pull them through the seal. Use a pipe wrench to turn the shaft and once the worm gear disengages it will pull out the front of the tractor. Put some grease on the keyed shaft at the u-joint when you reassemble. It will make it much easier to get apart next time.
Some tips: Replace the seal that the shaft goes through. Cheap and easy to do with the radiator removed. The seal is readily available from the dealer. Sand,clean up, and lubricate the shaft before pushing it through the new seal. Pull the top cover and determine what if any lubricant is in the gear box. Mine was dry and dirty. I cleaned it up and packed with grease. Originally they had gear oil in them.
Install or replace the thermostat. Easy with the radiator removed. PIA when you have to take everything apart to do it later.
Hope this helps.

I dont loosen those collars or use a pipe wrench. Once I feel confident the shaft will slide out of the ujoint, I just turn the steering wheel and the shaft spins right out.
