Removing Oil Pan 4500 backhoe 3 cyl diesel

I have a 1972 Ford 4500 3 cyl diesel backhoe. I am trying to remove the oil pan. I have removed all retaining bolts visable, and four 5/8 bolts which were at each end of the pan going into both the front end, and the lower transmission housing. This pan is cast iron and I expected it to be an easy job with all the weight. I cannot get any movement from the pan. Did I miss something? The service manual I have is for the 2,3,4,5,,and 7000 models, but the oil pan does not look anything like the one I have on my unit. If the gasket is seized to the block, is there a way to break it loose without damaging the block? Help, help, help, winter is coming on soon.

Have to roll front axle/support forward about 4 inches. This means propping up hoe subframe,draining hyd oil,hyd line going to hoe, draining coolant,hyd pump grive shaft,power steering lines, trans cooler lines if shuttle shift,air cleaner tube. Proably missed something else.

If you reread his post, he can't get the pan to even wiggle on the block. He might need to do all you suggest after he gets it loose???

If you're [b:86a57989e6]sure[/b:86a57989e6] you got all the bolts out, take a putty knife and drive that between the pan and block, into the gasket, and start working it around. I would leave a couple of bolts loose on the pan so it won't drop loose and bust you in the head....

In trade school I was tearing down a 350 Chevy engine. Guy had used non-detergent oil for 100K so the sludge was so thick it almost buried the valve springs in the head. We dug thru the sludge looking for the head bolts, got 16? out and the head was still tight. A Cheby fan told us to dig into the sludge in a lower corner and there was another bolt there.

There was. If there is any dirt still on the pan, dig thru it and make sure nothing is under it....

I have a 1971 Ford 4500 TLB, there is 6 pan bolts (4 in the front, 2 in the back) that look like all the other bolts that hold the oil pan on. The heads of the bolts tend to get covered up with oil dirt because of their location (indicated in red).

If you already have those bolts out it can still be a real pain to break loose. I did mine out of the tractor while it was on a engine stand, and even with all pan bolts out the gasket was sealed on good. (I thought I was going to break the oil pan). I took a thin chisel, started going around between the block, and oil pan, and it finally started breaking free when the gasket finally started to tear in half. I spent at least an hour getting the oil pan off, I don't know what they used for gasket sealer but that sealer is some strong stuff. You may want to space the front axle support forward just a little bit if you haven't already. Hope this helps.

Can't thank you guys enough. If you want to know something, ask a guy who's been there, and done that. And you are right about the gasket
sealer, that is some strong stuff. Haven't got it off yet, but with your advise and help I'm sure I will. Never would have found those four
bolts at the front without your help. One picture is worth a thousand words. Why didn't they put one in the maint. manual that matched the
engine I have.
Thanks guys.

I got that picture from the parts book, I don't have the industrial supplement shop manual for the industrials. I would assume the industrial supplement shop manual would show the industrial style oil pan.

You just need something to get in between the block, and oil pan to get the gasket to start tearing. While I was working on mine I was hoping I wasn't going to hear a snap sound, and see the oil pan bust in half.
