[Farmall] !@#$% cub oil leaks / gears grinding

David,
    Remove the front radiator casting assembly and you should be able to pull the crank pulley.  It will pull very hard.  It is a press fit and you should use a backing plate or bearing puller behind the pulley to keep from breaking the flange. 
    There are those who have made a puller for the pulley.  Go to www.farmallcub.com then go to the forum and do a search for crank pulley.  You will see what they used.
    The leak from the rear sounds like a transmission full of water from the description.  Drain and flush with kerosene and refill to the proper level.  (3 1/2 pints) and that should solve the problem.
    As far as the clutch goes, adjust the pedal for 1" free play in the pedal and see if that doesn't help.  If it doesn't, you can set the clutch fingers through the access cover in the bottom of the torque tube.  Detailed instructions for this can be found at farmallcub.com as well.

  Hello and regards, all.  I have some oil leaks that I need to deal with over the winter, and thought I'd ask if there's anything I should know before I start, etc. 
     
    The front main seal is leaking.  Can this be removed and replaced externally?  In other words, can I just pull the radiator and crank pulley and somehow pull the seal?  Is there any special tool / technique?
     
    Second - there's a pretty good leak from the clutch access cover - seems to happen especially after a good load - plowing or harrowing - it's a nice foamy, mochachino color, and I'm guessing it's coming from the rear end.  I assume there's a front seal there that's leaking.  What does that r&r entail?
     
    Third - the gears grind when shifting, unless the engine speed is dropped way down.  Is there an adjustment to the clutch that'll give it more throw?  There's no bearing noise or anything.
     
    Other than those problems, the tractor runs great and while I know it's a great time for a major teardown, I'd like to avoid it if possible.  I'm not looking for any new projects right now...  :-)
     
    Thanks for any help with the above.  I had the tractor set to 54" wheel spacing all summer for cultivation.  I just narrowed it back down and forgot what a pleasure it is to drive - much easier steering, much more maneuverability.  I suppose I've waited long enough and will have to get the snow plow and chains mounted now...
