    1998 John Deere 425 transmission leak repair

    I have a 1998 JD 425 AWS that has a rear end leak . I removed the transaxle and found the differential lock seal displaced and leaking. I plan on replacing that and I am wondering what other seal I should replace as long as I have the transaxle out. The right side of the transaxle looks dry. No other obvious leaks. Thanks

    425 differential lock seal

    Removed the diff. lock seal. It is very hard and loose, not sure what is supposed to keep it in place. Are they glued in? Also can someone tell me where the drain plug is located. Thanks

    I would worry about the case seals when they leak.

    Use a good aviation gasket sealer on it. The brown gooey runny type and it should help hold it in. They have a habit of coming out so use that and let it dry. Should be fine then.

    I canít remember where the drain plug is so Iíll just give a smart Alec answer and say on bottom.

    Isn't the transmission a K92?? Look it up at the Tuff Torq site.

    Thanks, found the drain plug. Any other gaskets or seals I should replace as long as I have the trans out? Thanks
