WVKid 08-30-2012 15:47:29 71.178.204.47 Report to Moderator	Wow!! The stuff I don't know about my NNA. lol I have a hydraulic oil leak in the bottom of the transmission pan and it was putting a nice puddle of oil on the driveway. I saw it coming from a cotter pin and said what the sam hill is it doing there? I go it out and coated a screw with JB Weld and fixed the leak. I then found out by reading an old post from 2009 that the cotter pin is supposed to be there and it's supposed to leak. The post said it keeps the clutch from getting soaked in oil. I'm going to replace the cotter pin but I would like to know if I can use a smaller pin? The old pin is about the size of 5/32" and seems to leak too much. Can I use a smaller cotter pin? Would like to know why if the cotter pin was in the original design? Thanks, WVKid [Reply]   [No Email]

Edit: If I was the dictator of all the world the first thing I would do is outlaw the use of JB Weld This post was edited by Ultradog MN at 19:23:42 08/31/12.   [Reply]  [No Email]

In the long ago time before weed spray, weed control was done by "shovels" (V-shaped devices) that just scrapped the DRY dirt between rows of crops (corn, tabaca) the cotter keys kept the tranny drain hole OPEN. Otherwize, oily dirt would clog the tranny drains. .........dirty Dell   [Reply]  [No Email]

Do you want to know which? Drain the oil from the trans and let the tractor sit for a few days and check the leaks. If its still leaking, its engine, if no leak, probably trans.   [Reply]  [No Email]

I drained it into a large pan and I am going to pour it back into quart bottles. Spec's call for 6 quarts. Old fluid looks milkie, and not sure what type to buy. Thanks, WVKid   [Reply]  [No Email]

Also your transmission could be over full.Pull out the bottom bolt on the round dipstick cover (by your right heal ) and let the transmission grease drain in a pan till it stops leaking out.Then put the bolt back in.   [Reply]  [No Email]
