Transmission fluid leak

damianhaarhoff · Apr 11, 2013

Greetings. My 9n is leaking transmission fluid from where the right arm attaches to the tractor (not sure what it is called, but I attached a photo). I removed the one bolt (the smaller one) but the big one just seems to turn and turn without coming out. Does it just pull out? How do I get this part off so that I can replace the gasket (assuming that there is a gasket here)? Alternatively, would you recommend a JB weld around it instead? Thank you for any help you can provide on this issues!

there is a gasket.. but I reccomend you check your explode dparts diagram while getting some cribbing ready.

save the jbweld for gluing bolts to the tops of soda bottles.

damian........while there is a gasket on the lower 3-point link, the lower link is actually held inplace by a BIG nut INSIDE yer axle trumpet cotter keyed and torqued to 150ft/lbs. It should be intuitively obvious, you will haffta remove all 10-nuts that hold the axle trumpet to the diffy.

NOTE: the 8N has a taper'd lower link pin that semi-solved the "leaking" problem, but it still can be wallered out.

While JB Weld is good stuff, you will haffta drain 5-gals of hydro-tranny fluid and CLEAN the trumpet hole so the JB will stick and cure. Many times the lower lift hole is WALLERED OUT and the ONLY way to seal the no long round hole is to J&B it. (still torquing the inner nut to 150ft/lbs)

I saw a sign the other day, "Harleys don't leak, they just mark their parking spot". Yer 9N is marking it's spot. Iff'n it really bothers you, a clever shadetree mechanic could figger out a way to bailin'warr a tuna fish can to catch the drips. As long as you have at least 4-gals of hydro-tranny oil, yer good to go. ........dripless Dell

What Dell said and the pictures show... You'll have to remove the wheel pull the axle trumpet to get to it from the inside. Can't fix it from outside. Considering that, you might grow to like a little leak, but it will continue to get wallored (sp?) out more and more as time goes on, so if you plan to keep it you might just bite the bullet (if you can find any bullets anymore!) and do it right, and do whatever else needs done in there while you have it apart.

Its best to leave small leaks alone.My truck has a small leak on the rear seal.Fixing it would be a major job.Some things are best left alone.

Thanks to all of you who responded. You have been very helpful and I think I know what to do now. As always it will be fun to learn something new about fixing this tractor. Since I am not very experienced but eager to learn, I sure do appreciate all the help!
