    Wigly shafts that need new seals usually also need new bearings... A bad bearing will let shaft wobble eat a seal.

    excellent point. when you get ready to rebuild, you might need to ask yourself why the seals went bad. could it be a bad bearing, and if so, was it ever run dry (no oil) by previous owner and did it get hot frying more seals or bearings or shafts in the process?

    Yes you can cure your problems if you would use EP-0 grease. You will have problems with grease gun grease.

    Make sure the Grease has the EP additive. Corn head or cotton spindle grease without the EP additive will cause premature gear wear.

    After learning that I oversee offshore drilling rigs she offered to send me a free quart to try out. I will keep the group informed of the results.
    Well, I finally tried the 880 Crown and Chassis Grease (NGLI #00) in my tiller gearbox. It is a very thick grease but I could barely pour it out of the container in to the gearbox. I used the tiller all day without a single drop leaking out. This stuff is great! I would highly recommend it to anyone with a gearbox that leaks.

    What would be the risk in substituting cornhead grease for 90W gear oil on a flail mower gearbox? My gearbox doesn't leak through seals/gaskets but the breather cap is situated right above the gears which throw oil at the cap then leaks out through the breather vent. I am assuming that cornhead grease would be less likely to be flung up into the breather cap and therefore would not leak out.

    If it was me, and the seals were good.. I wouldn't go to a grease.. even a light one.. I'd make the breather cap taller with some fittings and a short stand of pipe..

    I've tried. Trouble is it is an Italian gearbox and the threads are not quite 3/8 NPT and not quite the British equivalent. I guess I'll keep trying to find the right size extension piece. Ordered a metric/imperial thread gauge so maybe that will help track down the right piece.

    It's got to be some sort of standard thread... find what it is.. and use it.
