the pics from "clueless on a farmall tractor"

James A. Nicholson PH.D. Technology Education, and Technology Management, St. Cloud State University, MN.

In your top picture you can see everything that you need to change the oil. You can see the oil filter canister, the drain plug fitting on the bottom of the oil pan, and the oil filler tube attached to the valve cover. You removed the filler cap/breather to get the hood off.

If you look at your last picture where it shows the oil pressure gage and dipstick you can see the oil filter canister. It takes a 3/4" wrench to remove the bolt on the top of the canister. That bolt is about 8" long since it screws into the oil filter canister housing at the bottom of the filter. If you gently tap on the side of the canister it should come loose. Take a small screw driver or other sharp instrument to remove the old o-ring from the groove in the housing. It may be so hard that it feels like metal in there but it should come out. If you put the new o-ring in the groove and if the o-ring doesn't drop down below the top of the groove then you definitely have an old o-ring in there.

The oil is drained out through the drain plug on the bottom of the oil pan.

The oil is poured in through the oil fill tube attached to the top of the valve cover. You may think that you are pouring the oil in the pistons but you are just pouring it on the top of the head. There are oil return passages to drain it back down to the oil pan. 5 quarts should put the level above the lower petcock. 6 quarts should fill it to the upper petcock.

Regular 30W oil will work just fine. If you live where it gets cold and plan to run it in the winter you may want to go with 10W-30 or some other multi-viscosity oil. About the only oil that you can get these days is detergent oil. That is ok. After running the tractor for 10-20 hours you may want to change the oil and filter again, just in case a lot of sludge has loosened up.

Your oil pump is not in the housing next to the oil pressure gauge and oil filter canister. The oil pump is located in the bottom of the oil pan. The pan is the lowest point in the engine so that is where the oil drains to. The oil pump sits in the oil to get its suction.

GET THE MANUALS. And sitting on a tractor and driving it for years does NOT make someone mechanical. It just means that you can operate the clutch, gear shifter, throttle, and you are able to steer it. These little engines were used in the A, B, C, Super A, and Super C with minor differences. They are about the most basic engine and very easy to work on and maintain. Randy

It says on the side of the hood you have a Super A, however it doesn't have a Super A engine, unless it is a Super A1. It doesn't have a Super A torque tube. You have a C-123 engine, used only in Super A1, 100, 130 and 140 offsets. It's not a 140 engine as the dipstick on 140 is forward of the oil filter. It also has lights that were used on SA1, 100 and 130.

If you truly want to identify what you have, check out all these items, and when I say ALL, I mean every damn one of them. None of this jumping from one item to the other without resolving anything, like you did on the other thread. Each casting has a casting date code, about 1/2" high digits and are day and month by number and year by letter cast in place. Between each of day, month and year it has what looks like a round head blade type screw cast right into casting. The letters are X-1952, Y 1953, Z1954, A-1955, B-1956, you can go forward or back from there. Don't bother with all of them, just do engine block, torque tube, hydraulic unit and transmission-rear end. The results of those will help identify what you have. Just an example on the hydraulic unit in your photo it shows numbers. The larger numbers on top are the part number, just below it is the date code.

Next go to engine just below number one spark plug on engine block casting. Clear away dirt and you'll find a machined flat surface. You will find letters and numbers STAMPED, not cast in place. Give me all those letters and numbers in order.

In the earlier thread folks advised you to look under seat on left seat support for serial tag, and that is true until sometime in 1954, after that the serial tag moved to left side of clutch housing. I suggest you look there for a serial tag.

If you give me everything I listed in the last three paragraphs, I can identify exactly what you have. I agree, I came down quite hard on you. I should point out, most of the respondants of the other thread, made one basic mistake, "Trying to give you advice without finding out exactly what they were giving advice for." Just one of the pitfalls on forums.

BE careful with the attitude. You came here looking for help and advice and got very good, sound advice from people who know the tractor that you are trying to work on.

Many here can help you with their lifetime of experience with these tractors, and from their lessons learned from the school of hard knocks.

If you cop too much of an attitude with the guys here they"ll clam up tighter than the bark on a tree and you won"t get any help at all!!

A very wise old sage once told me to be careful when you climb up the ladder, not to piddle and pooh on the rungs as you go, "cause sometime you may have to climb back down.

That being said, one thing that you may do is to look and see if your Grandfather has a manual for this tractor. If he had it for a long time it"s very possible that he had an owners manual for it.

From the looks of the tractor in your pictures, it looks like he must have used it a lot to cultivate with (lots of caked on oil and dirt). Take a screwdriver or a pick and scrap the dirt from the bottom of the "silo" in front of the oil gauge. Loosen the bolt that is on the top and gently tap on the side with a rubber mallet. It should break loose and you"ll find it"s a canister and it should have an oil filter inside of it.

Good Luck. Edward

Looks like I'm not the only early bird around here. Getting snow here in North Central MD, supposed to start sleet and freezing rain any time. Don't mind the snow but they can keep all of the ice.
