If you have a shaft seal in lieu of a stuffing box, you should not be using any grease. The shaft seal uses a carbon flange and stainless steel rotor as a seal. See the following link. If there is a leak, it might be possible to reseat the rotor, if not you will have to replace the carbon flange.
PSS Shaft Seal
The Volvo dripless seal is very different from the PSS and it DOES require grease. Be sure to use the Volvo grease. I have found the easiest way to grease it is to pinch it and create a gap at the front edge then use a West Systems epoxy syringe filled with the Volvo grease and just squirt a little in there being careful not to harm the inner lip seal. You don't need a lot of grease but should do it every 100-200 hours of use or when necessary. If run dry without grease you may have toasted the inner lip seal.
