Oil leak under trans on TC29D

[DONOTDELETE]

My TC29D (hydrostat) has an oil leak coming from a cotter pin that hangs down from a hole that's near the center in the bottom of the transmission. It only leaks a few drops while it's parked, but I don't know how much it's leaking while I'm using it. The tractor only has about 40 hours on it. Has anyone else had this leak?

Danny,

The cotter pin is there to keep the drain hole clean. DO NOT REMOVE! That cotter pin has been used on a jillion tractors. The hole is for draning of any fluids that may enter the bell housing.

The most important thing to do is try to identify the oil. Engine oil means the rear seal is leaking. Hydro or rear end oil is input shaft or other gasket leaking at the front of tranny. Check all dipsticks closely and see which one is going down. If it was bad enough with a stick shift, you may notice the clutch start to slip. I would monitor closely and let dealer know right away. It is good to notify even if it was to stop after a few hours more on meter just to let eveyone involved know. Drip pan will let you know how much is leaking when parked. A diaper would let you know what is leaking during run times. I would not ingnore or procrastinate on it. Good luck and keep us up to date on any resolve.

PS, don't let anyone talk you into a seal swelling additive on such a new tractor.

Danny, when I first read your message, I wondered if you weren't talking about the bell housing. I do believe that Hawgee has given you all the right answers. Contact your dealer, as he said, and let us know what happens.

I just got to add this story. Most have heard one close to this. If not, you are now warned.
New farmer thinks cotter pin is stray loose one and removes it. After cleaning out drainage ditches for the fall weather and parking the tractor for winter, youm guessed it. Water had gotten into bell housing and hole got plugged. Nothing but rust when he went to run it in the spring. Clutch had rusted to flywheel and pressure plate. Throw out bearing did not spin anymore.
One machanic told of the time when one came in for service, crawled under to drain fluids and jiggled the pin, whooooosh!!! He said you must check and wiggle the cotter once and awhile. If you do have a leaking seal and the hole is plugged, how ya gonna know? Wet faced. [img]/w3tcompact/icons/shocked.gif[/img]
Oh and Danny, your is the first I've heard of with a leak. Good luck.

Danny I bought a new ford 1520 back in 1995. About to months later it started leaking same place as yours called the dealer they came right out and picked it up they said it was a bad hydro seal. Well about five months later it started leaking again not much just a few drops I kept that tractor for about five years and every year it would get a little worse so I got rid of the tractor.

Good info Hawgee Now atleast I've been warned. Just hope that never happens to me. The wet face I can relate to oh yea that was the last time I was changing the oil in my tractor and the oilfilter slipped and guess what--not good.
