  • Oil leak part?
  • Can anyone tell me what this piece is, and what it's for? It sits on the back of the oil pan, is loose/easy to push up in, and has a very slow oil leak coming out of/off of it. The oil leak seems to get worse/faster when the tractor is used for a long time and the oil is hot.

    Sorry if the picture doesn't work...Photobucket free doesn't allow direct sharing links anymore.

  • Sounds like you have a rear main seal leak. The hole with the cotter pin allows the oil to drain out. Otherwise it would fill the bell housing and soak the clutch. Keep an eye on the crankcase oil level.

  • A Cotter Pin, should be two, to keep drain open. I'd advise you to invest in the ESSENTIAL MANUALS to learn all about your machine.

  • No. The drips indicate that you have a leaking seal(s). You won't soak your clutch if the cotter pin is there to rattle around and keep the hole open to weep. It comes down to how much is leaking - several drops after use are something you might tolerate. Just use your judgment on how much oil you are losing and what you are comfortable with to justify splitting her and replacing the seals.

  • The cotter pins are there to keep the drain hole open so that fluid will not build up in the clutch housing. The transmission seal and the rear main seal are not supposed to leak, but after many year the do. Try to determine if the fluid is engine oil or hydraulic oil. If it is hydraulic oil, it may be leaking because the transmission - hydraulic - rear end is overfilled. It may be overfilled because the previous owner overfilled it, or there may be a lot of water mixed with the oil.
