How do you remove lower water pipe to get water pump off of a John Deere 720 ?

Remove bolts in elbow at rear of tube.
Should be a drain plug in the elbow
When I put mine back together, I expected it to leak, but it doesnt

If it's been there "forever", it takes cussing, blood, sweat, and tears, and when all that failed, a smoke wrench to heat up the castings where the hard, brittle, rusted O-rings are enough to burn them out.

I think on those you can remove the water pump, pipe and casting at the head in one chunk. Then you can take it to the workbench. Heat on where the o rings are to burn them out saves a lot of time and aggravation.

Always inspect the tube rust lurks in them. I use
sandpaper clean oring groove and where it slides
in very smooth,then coat oring with vasoline and
the area where it slides in. Apply generously.
Use vasoline not pressure grease.

I use silicone sealer on those O-rings. It aids in assembly and once dry it fills in the pits and helps it seal.
