We replaced the shaft seal on one of our Frick screws 193S TDSH RWB II. After putting it back together and running it over night more oil then before leaked from the seal. When not running ammonia leaks from the top area of the shaft. If we run the pre lube pump when the screw is not running oil starts oozing out from the bottom of the rotor. I think maybe alignment, clean up the assy. and reinstall again, thrust or end play, or just try to replace the seal again with a new one. Any suggestions?
