4000 select-o-speed bands

I was 21 when the tractor was delivered and am now 50 and still driving it. The SOS has never given a moments trouble and I would like to keep it that way.

I was taught to adust the banks by the book.

That way is nonsense!

Here is the procedure I came up with myself after a few hours of trying to hold the threaded rod while the selflocking nut was turned and the screwdriver slot on the threaded rod got worse and worse.

This is the easy way.

The Pto is notorious for not disengaging except when there is a load on the pto. Usually then it will work OK.

Be sure to disengage the coupling between the transmission and the differential to prevent possible injury.

The bands are easy to adjust but the hydraulics of the trans. must be working in order to do it. If you will put the transmission in the gear a particular band is supposed to be engaged you will be able to release the lock nut without the adjusting screw moving. If on the other hand the adjusting screw moves with no resistance when you have it in the gear that is supposed to have that band applied you can assume you have hydraulic problems with what ever is supposed to be applying the band.
After you have turned the lock nuts back on each band then you can turn the adjusting screw in till you feel the engine begin to load because you will be doing the same as trying to put the transmission in more than one gear by removing the clearance in the band that is supposed to be disengaged at the time. Then you need to turn the adjusting screw out 3/4 turn. Put it back in the gear that puts tension on the adjusting screw and tighten the locking nut. The reason you do it this way is because it is almost impossible to hole the screw while tightening the lock nut when the band is disengaged. Do this procedure on all three bands except that the front #1 band should be backed off only 1/2 turn because it is the smallest diameter of the 3 bands.
