Why don't you loosen the line that goes to the rotary hydralic union on the end of shaft for we can eliminate hydralic or electrical problem. Maybe you should have gearbox in high and then while holding cylinder varible switch toward low hit the throttle from fast to slow a few times to see if the RPM is slowing up for you. You should be able to slow up the rotor while under load and that should help get it slowed down. You should be able to loosen the line at rotary union and pry the lower sheaves all the way apart. It is very important to grease the zirk on the upper shaft and very the speed from fast to slow daily. It could be that there was not enough grease which could of failed the spring can torque sensor and or siezed the top set of sheave hubs together. You will want to try get the top set of sheaves closed up or slowed up before removing nut that holds torque senser on for there would be alot of spring pressure that will release when the nut comes off the threads. If torque sensor is working proper and sheave hubs are not binding up you should be able to kill engine before sliping the belt and pluging the rotor.
