    Ok guys, another 47" question: One of the seals on the PTO gear box is leaking and I now have the seal in my possession from JD. Has anyone here replaced one and if so, so you have any tips for this gear box? Thanks

    I don't sorry Erik, my 47 is the chain-drive Quickhitch version.Still I can't imagine it's anything unusual. Are you planning to swap out just the seal? If so, you can use the two-self-tapping screws trick to dig the old one out, and a piece of clean pipe as a drift to knock the new one in. Before you do install it though, inspect the seal surface on the shaft for a wear groove. If there is one, drive the seal in either further if it can go in further, or just short of where the other one was e.g. 1/16 to 1/8" shy of the original depth, so that the seal bears on a new, full-diameter surface.
    Also, check before you do anything for play in the bearing - your seal replacement might be short-lived.

    HI Neil,

    Just the seal. I will try the two screw method and then push the new one in. I will check out your listed concerns above. I don't believe there is play in the bearing but I will double check. Thanks for the input. I will hopefully do this tomorrow.

    So I used Neil's suggestion of self taping screws combined with a tie-rod puller to remove the seal. Worked perfectly. I also had the correct size PVC pipe lying around and used it as a drift to set the new seal. All is well. Thanks for the response Neil.

    Great outcome! No oil leaks?
