Unstyled b mag flange gasket

Is there oil in the drive lug area and does the flange gasket seal oil in the govenor? I removed the mag and then the left govenor case cover to check govenor timing. Slightly tore the mag flange gasket and now have a small oil leak at the mag flange. Honestly I don't recall seeing any appreciable oil in the drive lug area when I had the mag off. Do I just have a bad flange gasket? Or something else?Tractor runs and sounds normally.
 
Not much oil in there, no directly slung oil anyway, mainly just oil mist from crankcase. But it may be gathering into a puddle right at the torn portion of the gasket. Some of these were critical as to gasket thickness and require a pretty thick one (or two) in order to prevent the drive lugs from riding the drive slot making the mag move visibly while running. Hard on mag bearings for one, avoid this situation if possible.
 
Take it off and measure with a caliper. Get gasket material at local autoparts store thats close to your old gasket thickness. Its more of a shim then it is a gssket.
 
There is no seal there. Oil makes it way past the bearing on the drive flange. That's why there is a drain hole.
 
Along this same line, I have short lug xh spec 1042 but the drive coupler has no markings. Anyone know if drive couplers were a certain degree coupler? 25-30-35? Thanks
 
The bearing has a seal. Do you think it was actually designed by Deere to leak all over the top of itself? If oil were ever meant to be there the drain hole would send it back inside the engine. The hole is in case moisture gets in there, namely rain, since most sat out in those days, being that very few farms had tractor sheds.
 
You can buy the gasket for a couple dollars- making that one is not ez. Some tractors I've had do not have one in there at all because it got lost or broken but still work fine. As long as the mag mounts up tight without pressure on it's shaft that's all you need to care.

Think there may be some misunderstanding here. I understand the mag itself should not have any oil present and agree there is a seal there. However the govenor shaft/ coupling only has a bearing, cup, and cone with no formal "seal" per se. Looked closely at my tractor, a disassembled complete govenor from my parts tractor and JD parts schematic. I find it hard to believe all three of these examples are somehow missing the mystery seal.
