Thank you everyone for your responses and knowledge to help me out! I did get the Operator's Manual and read through that thoroughly; I got a lot of info to help me as well. I got the pony motor carb rebuilt and spark plugs will be installing those this weekend. Just got back from the CAT dealer with the following:

Fuel Filter Elements
Oil Filter
20 gal of 10w-30 oil
5 gal of 85w-140 gear oil

They didn't have the "Large Button coupler" adapter for the grease gun, so I will take a look online and get one.

Here is my plan:
  1. Drain and replace the pony motor engine oil
  2. Clean, blow out gas tank for pony motor and place in-line fuel filter
  3. Drain small amount of the engine oil to verify no water/coolant in oil
  4. Top engine oil/coolant
  5. Grease all points
  6. Top off transmission and final drive with the 85/140
  7. Clean both air cleaners and add oil
  8. Start pony engine and main engine (Per the Operators manual and the points everyone above mentioned)
  9. After letting the dozer run for a while, let it cool to warm.
  10. Drop the engine oil and replace oil and filter
  11. Replace the Fuel Elements and re-prime fuel system
Am I missing anything?

Thank you for the explanation of the oil filter! Mine has the T handle.

Yes forgot to talk about the grease. I am guessing to late to look around for grandpa's bucket grease gun. Because he sure had one if he really used old Cat's. Just look up Alimite grease fitting and figure out what size is on your tractor. Then use a regular grease gun and buy "corn head grease" in the tubes. The seals on the roller will blow out at a very low pressure so don't use a battery powered grease gun. Just pump carefully and at the least amount of resistance STOP.

It seems your dad and grandpa would of had it greased before storage so maybe just a few pumps so you know there some in the roller would be good for several hours of putting around.
 

Unfortunately the older grease cart with the fitting was sold off with the rest of the items. I did order the adapter online that will fit on my normal grease gun, so thank you for the info!

Well I forgot about the points. Tried to clean them up and used the aluminum foil trick, got some spark, but not enough. I'll have to get that ordered. Drained and refilled the pony engine Oil. Checked the main engine Oil filter, it's the metal screens so I'll take them back and give them a good clean. Fuel injector pumps are frozen, so I'll have to take them apart and clean and reinstall. Checked the main fuel, it's got a lot of rust on the walls and the fuel is bad so I'll have to drain the tank and clean it.

When you checked for spark were you just looking at the points themselves or at the electrode on the spark plug itself? I have had a few points/mags not produce any spark at the points and have good spark on the spark plug. If your points are gapped correctly try it and see what it does.

Not getting consistent good spark at the plug. Points were set 0.020 per manual.
