Leaking trans/hydro fluid

[Nute]

Just bought my first 8N tractor and am in the process of fixin her up and have a leak that needs to be taken care of but not sure how to fix it. Can anyone tell me what keeps the lower link support shaft from leaking fluid? The I&T shop manual (Page 81 #22 also page 138 #21)doesn't show anything as far as a seal goes to keep this from leaking. Thanks in advance for your help.

Nute.......yep, thats the lower link pin leaking and unfortunately you'll haffta remove the rear axle trumpet to gitt to it. Its a tapered pin that seals tight when torqued to 150ft/lbs from inside. you haffta remove the cotter-keyed castleated nut to do it. Iff'n you letter go too long, the hole in the trumpet gitts wallered out and will never stop-leak. Its not a too bad job, just remember to swipe yer trumpet gasket with HOTWATER to relax it so it fits over the diffy studs (torque 40ft/lbs) ......Dell
