Nilram 09-10-2012 08:16:39 208.123.15.242 Report to Moderator	I have a NAA that I'm trying to put back together(the parts came to me in a box) When I poor the lube into the fill hole on the steering sector it appears to flow into the tranny. Is there a plug or something that is suppose to prevent this from happening? I plan on filling the sector with grease but I don't want it to drop into the tranny as well. Thanks for your help [Reply]   [No Email]

I put RTV on the welsh plug,rtv on each mating surface of the shims,and also installed new orings on the side covers,and new sector shaft seals. If it still leaks go to john deere and get corn head grease,and pump the housing full 3 tubes I think. I still have the corn head grease handy but,havent used it yet. I discovered my steering box leak replacing the oil pan gasket. Billy [Reply]  [No Email]

Leakage will go into the bell housing, or down the side of the tractor if it comes out along the sector shafts. [Reply]  [No Email]

On the SOS the sector closes the transmission itself. I'm thinking the 5 speed does as well. It does appear that I'm in error on the 4 speed, however. My apologies. :oops: [Reply]  [No Email]

Beginning 1/59, during the production of the 01 series, it changed to a 3/8-18 threaded plug. Therefore, you need to get a measurement (I'd take a wild guess and say it's likely 3/8 as well) and go to your favorite auto parts store and get one. The guys are in error about any sector leakege going into and out of the bell housing, You are correct that it will leak into your transmission. [Reply]  [No Email]

IE.. OUTSIDE and ahead of the tranny. 2nd pic is of an 8n trans I have in the barn. notice the trans cavity.. and thent he clutch bellhousing cavity.. and that the steering box sets above that empty cavity. hard to see how a drained steering box is gonna run into the tranny???

I know my 660 does and I think they use the same steering gear. Is it there? If not, the oil will drop into the bell housing and come out the drain hole on the bottom (the hole with the cotter pin). The oil should not be getting into the transmission. [Reply]  [No Email]
