 Topic: B questions oil and such.
Posted: 04 Nov 2016 at 9:04am |
|
Just got a 1950 B. My question is there's a drain plug in the torque tube right where the left brake pedal crosses under. It was loose and oil leaked out. Where is this oil coming from ? I stuck my finger up in there its full of crud. Also reccomended oils for a full front to back change ?

First Congratulations on obtaining my favorite Allis Chalmers tractor - the B. You will find it to be a very dependable and easy to work on unit. In answer to your question the torque tube does not have an oil drain plug. There is a drain plug on the bottom of transmission and on the bottom of the PTO housing. The torque tube has a shaft that transmits power from the engine to transmission. There is an opening in the clutch housing so that the throwout bearing can be greased and the fingers adjusted. I am not familiar with the plug you describe cause there is no oil in the torque tube. As to the fluids used in the transmission it depends if you have a hydraulic lift on the B. When I sold them we put 20W NON DETERGENT oil in the transmission and PTO. It fills from the plug located just behind the clutch pedal. However, with today's newer oils many use hydr trans fluids there and reports indicate it is very successful. As to the engine. If this is an older unit not rebuilt I would stick to non detergent oils. We used 20 sometimes 30 wt oil. You can check the age of the unit by finding the serial number. It is located by the shift lever. There is a listing of serial numbers on this site so you can determine the age. Be certain to clean the serial number area so you can get an accurate reading. You will find all the assistance you need here from extremely qualified individuals. Do not hesitate to ask. Would love to see pictures of another B. Take good care of my favorite. Good Luck! Bill Long

Thanks for the info. The plug I am talking about is at the end of the torque tube where it bolts to the tranny. What confused Me was I didn't think oil should be coming from there. It didn't at first it sat in my shop several days and never leaked a drop. I got it out and drove it around then parked it. The next day I noticed oil on the floor it it came from this plug? I removed it and a tiny bit more came out I stuck a air hose up in it aand could hear air blowing out up around the clutch end. So I'm wondering is this oil leaking out of the transmission into the torque tube. I plan to put a belly mower under the B and use and enjoy it. She's a little rough and has a homemade drawbar and the lift doesn't work. However the engine runs like a sewing machine. As to your last comment I wasn't in the military buthave lots of family who were and still are. I always heard Ky and TN boys got a rifle. Ever heard the term Kentucky windage. Thanks again.

If the oil is coming from the clutch inspection cover and if it's not grease but oil then it can come from two sources. One of those being the rear main engine seal and the second is the transmission input shaft seal. A few drips is no big problem as this is a 50+ year old tractor.

everything Stan and Bill said is correct... Oil in the torque tube has to drip from the motor rear seal ( or wick) , or the transmission front seal. There is no drain plug in the torque tube as it came from the factory. Drains are in the center bottom of the transmission, the differential, and the pto housing as Bill said......... you fill all 3 housings from the 1 inch plug by your left foot... about 8 quarts of universal tractor fluid or Hytrans.

Hello oldways, I'm glad you asked this question. I recently purchased a B myself. I was changing the transmission fluid today and I noticed the plug you're talking about. However there was on plug in mine, just the hole. The plug may have been lost, but I figured it didn't have one because as stated above the torque has on oil in it. Mine had oil and gunk in it as well. I assume the oil was from the transmission since the hole is right in front of it, but I guess it could be from the engine (maybe both). I used Traveler premium universal transmission fluid from tractor supply in mine. I only used 5 quarts, it seemed full. I'll check it again tomorrow, I'm sure Steve knows more than me. Wished I could have more help and good luck with your tractor.

Oldways, is there any way you could take a photo of this " drain plug " in the torque tube? It might clear up a few doubts. There is no "
drain plug " in my B torque tube.

Here's my question...my 39 has about 3 hours on it since I got it. I don't know the history, or if it has detergent, or non-detergent in it.
What should I put in it? I doubt that it's been rebuilt...

1939, several will disagree with me, but what I have done is put 10w30 detergent oil in the motor. Run it 10-20 hours while checking the dip stick to see what the oil looks like. If it turns black, your getting some of the old crud broken loose. I might drain it after 20 hours and refill......I have never had " the crud will come loose and plug up insides"...all I have ever had it the motor start to cleanup and run better. I use to change the motor oil once every spring, and run about 20-30 hours during the year... These days I probably don't get to the change but every 2-3 years.

Yeah Steve, clear this up for us. My B has a hole in the same location. Right above the brake crossbar, just in front of the seem between the torque tube and transmission. Mine didn't have a plug like oldways. I put my finger in the hole but didn't notice if it was threaded or not. Oldways said his tractor was a 1950, mine is a '49. I noticed most of you all have older B's. Maybe it was something added later on. Good job on the photos Oldways. Ranse

I just split the tractor and the seal on the main shaft coming out of the transmission is beyond bad. That plug just goes into a little cavity in the torque tube. I don't know why its there. I guess an inspection hole. Anyway the oil is coming from the transmission into the torque tube. Stan It wasn't a few drips it was a puddle under the tractor. The drips were when I took the drain plug out.

You know, that is not a bad looking B. Interesting drawbar and seat. After all these years it is interesting what some modifications are made. Also, I do not remember that opening being there. I did not note a rear lift bar. You have the hyd but looks like it was not used. Tractor just for pulling. Heavy Duty drawbar. Steve Ill, we had several B's where a person put heavy duty detergent oil in them. It removed the crud and caused them to "pump oil" and really foul plugs. Put non detergent 30 oil in them and got quite a few more hours before overhaul. 1939, on that old a tractor I would put 30 wt non detergent in it. Ranse, You may want to set the B uphill for a while. There still may be a gasket dam between the PTO and Differential that keeps the oil from running away from the hydraulic when going down hill. Can also prevent a new oil fill from getting to the rear. Thank you all for what you are doing to keep my favorite alive and well. Good Luck! Bill Long

This might be the oil seal you need but you better check the AGCO parts book on-line to verify.

this is the generic number for the transmission input seal... I think... National #450162
-
-I have several tractors and have never seen that plug on the bottom... but most of mine are pre 1948.
I have heard the stories of detrgent oil causing problems, but I never had that.. and 30wt would be very thick in the winter... I still go with 10w 30 detergent.

Thanks guys. Hate to keep on causing trouble but how about the bearing behind the seal ? Also anyone have any pics of the hydraulic lever how it hooks up mines missing and the lift is pretty much all gone. But if possible I'd like to see if I can't get it going again. Needs some descent back tires also. I need a parts tractor haha.

Just one last thought on the mysterious hole in the end of the torque tube. I took a close look at mine again today and they are on threads in it. I don't believe there ever was. Out of curiosity I crawled under my D10 and looked, sure enough an identical hole in the same location, and it was unthreaded as well. I can't imagine why anyone would go to the trouble to tap and plug this hole, but I believe it's simply an escape hole to let oil out and alert the operator of a leak. Anyway, that's my opinion. I'd be glad to post you some pics of my hydraulic lever, but I haven't learned to post pics on this site yet. Good luck Ranse.

ok heres some pics of the tractor the second one of the hydraulic pump I posted because I would like some info on how the hydraulics work. the last two are of the " PLUG " or bolt in question
