1941 Farmall H

Ive got a 1941 h and ive got a leak in it. Its leaking transmission fluid and its comin' from the belly of the tractor its in the back of the engine block and under the belt pully. Its leaking from a plate thats got 3 bolts on each side? and its right in front of the drain plug for the transmission fluid. Is there a seal or a gasket that went bad? Thanks

Could be both there is a seal and a gasket. Most likely its the seal and you can get one from Carter and Gruenwald. Matt

There are four seals that could leak into that space. In order of probable:
Transmission countershaft to Liftall drive shaft.
Transmission input shaft.
Liftall pump input shaft fitting.
Rear main seal on engine.
If it rear end 90wt gear oil it will smell sulfery and strong. If it is, it is (probably) the seal on the countershaft. Drain rearend oil. Remove the Liftall.(heavy and a floor jack is a good idea.) Use a solid hard square shanked tool to remove the drive coupling. Lefty loosy and very tight. Remove the fasteners, replace seal.
If that seal looks good, (and it is stinky gear oil) it is the trans input shaft seal. Same as above, but instead of removing the coupler disk, remove the clutch shaft, and front trans input seal flange. Replace seal.
If it is engine oily stuff, but pretty clean, it is the Lift all seal. As above, but remove the liftall drive coupling from the Liftall, and replace seal. A brass drift is placed into the gears of the pump to lock it for turning the disk, lefty loosy.
If it is engine oil, Usually darker. (matches a sample on white paper from the check cocks.)
pulling the tractor apart, and replacing the rear main seal (and clutch pilot bearing and T/O bearing for insurance against doing it again soon)
The process is more involved and both the archives "search For" box, and responses to your questions will get you through it. The plate with 6 bolts is not a oil reservoir, taking it off will not dump massive oil. It will be grubby. JimN

You said it could have something to do with the lift all the only extras there are on the tractor is a draw bar and the belt pulley.. is the lift all still relavent.. and im kinda new to workin on equipment.. the plate i was talknig about... thats what i take off to replace the seal???.. thanks so much youve been very helpful

The lift all is the hydraulic system. It is located in the belly of the tractor. A manual (from here, or bindre Books) is really needed. The pump would be located just befor that plate. There are controls and output fittings on the sides. It may not have them, if not it will be one of the three other things leaking. JimN

You should be able to find photos on my web site that will help
