Water bearings failed while doing some slashing over the weekend. Managed to pull the pump off the tractor, after removing the radiator. But my question is, do I need to lubricate the "o" ring that seals the connection into the block or leave it dry? And do I need to torque the bolts holding the water pump to the block to any particular setting?

The technical manual seems to lack any information about the removal and refitting.

Thanks.
