1066 PTO runs without stopping

1586 Jeff

Recommended Posts

I put clutches in my neighbor’s 1066.  Now the PTO runs constantly if there is nothing hooked to it.

If there is an implement hooked to the PTO it will stop the PTO shaft when the PTO is disengaged.

 I believe that the brake pressure is off from spec, but I cannot find how to adjust it in the I&T manual that I have for the 66 Series.

 I have the International Harvester manual for the 86 Series and it is incredibly detailed, but it only covers the new style PTO, not the older style PTO.

 Thank you!!!

Pto brake is spring applied, clutch pressure overides spring pressure to releases brakes when clutch is engaged. Sounds like brake pistons shoes are shot or clutch pack has too many discs in it, clutch may have had play on bench, but once disc swell up after being soaked in oil could cause it to be to tight. Install a pressure gauge and make sure pressure drop to "0" when disengaged.
