I want to start my dad"s allis chalmers wd tractor.
However it probably has not been started in over 10 years.
what steps need to be taken to start a tractor like this ?

thanks
 
Battery or Mag ignition?
starter?

I would:
1. Drain the oil and replace with new
2. remove the valve cover and make sure none of the valves are stuck.
3. remove the spark plugs (note the firing order) and squirt some oil into the cylinders and then turn the engine over with the hand crank (if available) to recoat the cylinders
4. Check your wiring (plug wires, others)
5. check under the distributor cap to make sure it is clean
6. drain any old fuel; put some new gas in and open the carb drain to see if you get a good steady stream (dripping is not enough) you may have to clean the fuel system, and the carb (if gas was sitting in the carb when it was last parked)
7. try pulling it around with the fuel off (prime the oil pump and get everything relubed
8. turn the fuel on and try pull starting it
 
#1 I would make sure the engine is not stuck from sitting that long.
#2 I would fill the cylinders with ATF be sure to put the plugs back in and let it sit that way for a week or so while you do the other things I will list.
#3 depending on if battery of mag ignition I would at least replace the points.
#4 check all fluids and make sure they are full of what should be there not what should not be there.
#5 Check the fuel tank and fuel system for leaks and other such problems.
#6 I would make sure that the carb is not full of rust and that the float is not stuck. I would do that by pouring a little bit of fuel in the tank and watch for problems and also after letting it sit say 30 minutes that way pull the carb drain plug and see if you get gas out of the carb
 
I know after I worked with one that had sat for 5 years, the water pump had gone to crap (or was when it was parked there -- leaked like a sieve when water was in it), and the gas tank had to be removed and cleaned, the valve to the sediment bowl was plugged with dirt, all the fuel lines were nasty, the air filter was gunky, the air hose between the filter and the carb had rotted, and the carb itself was full of varnish crap that needed cleaned out and the float was bad.

So... If you get lucky, not all of that stuff. Provided nothing is stuck in the engine compartment, of course, which is even worse.
 
In addition to ALL of the other items mentioned in the replies, I would recommend that after you change oil that you pump the same type and grade of engine oil that you are going to use in the engine into the engine at the "T" on the right side of the engine block until it comes out of the valve rocker arm pivot shaft and rocker arms and until you get at least 15 PSI oil pressure. (I use 10W- 40 Synthetic oil in all of my equipment.) Be sure to FILL the crankcase to the FULL mark on the dip stick. Most tractors take more oil than auto engines. Install a new oil pressure gage (of the proper pressure range) if there is any question about the old oil pressure gage.

I also recommend that you run the first tank full of gas through it with a "chain saw" gas mix of 50 to 1 with synthetic 2 cycle chain saw oil in the mix.

When checking the valves to be sure that they are not stuck, oil them and the rocker arms & pivot shaft very well.

Be sure that the clutch is operational (not stuck) for safety.

When you install a new oil filter be sure to install the correct kind and type or you will not have proper oil pressure.

Hope this helps, Gordon
 
Before I would ever do a 2 stroke oil in a 4 stroke engine I would do a ATF treatment in say 3 gal of gas to 1 qt of ATF. 2 stoke oil is just a plain and simple lube oil where as ATF is a very high detergent oil that eats carbon and rust
 
Remove and flush out carb. We eliminate fuel supply issues buy getting a plastic tank off an old riding mower, and tying it up high to the air breather on top of the hood, for good gravity flow. This gets rid of varnish and rust issues in the old metal tank. (You will need a 1/4 nipple for carb., and 3 or 4 feet of rubber line.)
