I agree with old on using a cheap oil to get it up and running/flush the engine out. An H holds 6 quarts of oil.

When you are going to put some "good" oil in it, I would go with a quality 15w-40 diesel rated oil. Why diesel rated? Diesel engine oils have the zinc in them that a flat-tapped camshaft needs. New gasoline rated oils do not because the zinc harms catalytic converters.

Check the rearend gear oil to see if there is any water in it. Should be brown or black - if there is water in it there will be a "milky" appearance.

You can pull it with your pickup/SUV to see if it turns over. Only use 5th gear on the tractor for this or you will spin the engine too fast. Make sure the brakes are in good working order!!!!

Once you have it running, warm it up good to be sure the cooling system works well and that it holds good oil pressure even when hot. My overhauled H will run 70psi all day long, even in 100 degree weather. At idle hot it comes down to 60psi. They were factory spec at 75psi oil pressure.

Once you know you have good oil pressure, then you can shut it down and pull the spark plugs and do a compression check. This will help verify that the engine is recently overhauled.

Other things to check when it is running... listen for any whines, clunks, bangs, knocks, etc. Check to see if the PTO engages and works. Drive around in every gear listening for a clunk that would signal a chipped or broken gear tooth. You can also check to see if it pops out of any gears.

Drive in first or second gear and make a couple sharp turns each way listening for noises again. Noises while turning would signal a problem with the differential gears.

Oh yeah - take LOTS of pictures! Always snap a few shots right away when you get it home so you have good "before" shots. I always seem to start tearing down before I get a good picture...

I'm sure others will chime in with more things to check...
