| Pull the plug out of the angled hole on the LH side of the PTO housing mid way down. Use the special adapter (longer body and orificed) to gauge the pressure. With the lever completely down, there should be 0 pressure. If there is zero pressure and the PTO still turns, the plates are warped or the brake disks worn out which will require removal and rebuild.
If there is still pressure with the plunger down, there is an issue with the control stem. Since the stem has to be removed out of the bottom hole, PTO removal is usually the easiest way to repair. | |
