On the left side below the headlight there is a 3" pressed in plug. It came out and so did a lot of oil(hyd oil) I reinstalled the plug along with some sealant. I filled the hyd reservoir and checked the dipstick ok. My question is what is the purpose of the plug and should oil be in that area it seems the hyd reservoir is separate.
 
On the RIGHT side (ahead of the brake pedals) underneath the right headlite is a four inchish plug that is for the belt pulley. Hydraulic oil will run out of that hole when the plug is removed. Hydraulic/transmission oil for a modern day tractor works just fine in that compartment.
 
Thank you I should have said right side. Now that I know its only Hyd oil and I replaced
that I feel its ok to use it.What is the purpose of the plug? Is it so you can have access
to something inside?
 
If the dipstick says its full of oil, it is absolutely OK fine to use. The plug is installed to keep the oil inside the tractor ! If and when you ever use a BELT PULLEY, you'll remove that plug and shove the belt pulley attachment back in the hole.v
 
That little dip stick is for the hydraulic level only (10 wt. hyd or motor oil) which is separate from the compartment you discovered. If I remember right there are 3 compartments counting the hand clutch & Transmission & rear end. To check those level's the fill plugs are down on the right side and are at the full position and it takes 80-90 wt gear oil. People can use what they want but I think what the book recommends would be best. cleddy

Thank you all: One More thing. on top of the housing above the plug there is a fairly long
bolt with a lock or jam nut it has a tapered end and extends down into the compartment what
is that for? What drives the belt pulley?
 
You pull the plug out and install the belt pulley assembly in the hole. It slides in and the lock bolt on the top holds it in place.
 
Going from memory I think there was a dimple for when belt pulley was pushed in to engage and one for when it was not in use and pulled out and you used the foot clutch to engage & use. We had a WD with a special spiral Mechanism that allowed engage&Dis-engage the pulley from the seat with a rod. I always wondered if this was an Allis-Chalmers option or a "Farmer invention improvement"? This old tractor seen a lot of changes in its life trying to make it more like a modern tractor?Cleddy

The pulley from the factory is slid in and the ring of holes in the tube adjusts back lash on a set of bevel gears using the one large tapered set screw. A few aftermarket companies came out with hand operated slide lever setups. I have one on my WC. The pulley is turning if the foot clutch is not depressed.

Wow cleddy, that looks like a little greenhouse mounted between the fenders there, neato. Glad I'm not the only one rolling with a pumpkin colored front wheel, lol.

What are the odds? And the same side too. So many people end up painting their Old tractors
the more modern Redish-Orange and when they are done to much invested not to like it that
way. I wanted to do a test of Persion Orange ??? to see if after a while I was satifiyed
that it was the right one. I think it is pretty close.cleddy

Dang you have a pretty great shade of orange there, I'd be mighty happy with it. All I could find was some rattlecan "AC orange", and they didn't even have 2 shades of it so I figured I'd be less than impressed. But dang, your tractor there looks purty!
