460 PTO doesn't stop

I've been spending alot of time around this new to
me 460D. I haven't used it for anything productive
yet but notice that the PTO is always spinning, even
when shut off and locked off. I've heard mention of
a "kit" that can be put in to fix this? Any idea on
where to get this kit or the cost of it?? Any other
ideas?? Thanks!!
 
I had the same problem with my 560 and a mechanic told me to change the rear end oil and be sure to flush out the pto section with diesel fuelto get the sludge out and that was all mine needed and that was 15 years ago and all is fine.
 
If it is the planatary type, there are two adjusting screws under a small cover on top of the housing, one to keep it from slipping, one to stop it from turning when off. Instructions are in your operators manual.
 
If it has a little oval shaped dome on the top of the unit, This will work.
There are (usually) index marks on the lever base. The marks are at 50% of the travel From locked off to locked on. The adjustment is as follows:

Here is my take. Look at the linkage and be certain it has no lost motion, there are pins and woodruff keys in the system that can be loose. Fix if found.
Place the lever 1/2 the way between the latching points of on (up) and off (down).
Remove the little dome cover on the PTO box. Under this will be two lock nuts and two adjusting screws.
The PTO should turn by hand (engine off).
Loosen the lock nut, and turn the front screw in until you can feel the shaft start to resist turning by hand. Loosen it just until it will turn free, no more.
Do the same for the rear adjuster so that it can rotate free, but no more.
The front adjustment is the drive adjust, the rear is the brake adjust.
If the screws are down level with the adjustment lock nut top, the bands are worn, and will need replacing, or relining at a clutch shop. That is not quite the book way, but I have used it many times. JimN
