*****This is a cut-a-way view of the PSS Shaft Seal. It is critically important that TWO set screws be used on on top of the other to lock them into place. The o-rings should seat in the slots well and no grease or oil should be used when sliding the rotor onto the shaft.

*****The factory set screws come from the factory with thread locker already applied. It is the off white/yellowish stiff on the set screw threads.
