That sinking feeling. PSS.

When was the last time you checked the set screws on the shaft collar of your PSS. I checked mine yesterday, I had to my bilge pump was running after I shut down the motor. Both screws were not tight and the collar had moved up the shaft with the bellows barely touching it, not a great amount of water and a two second fix. It is now on my list of regular things to look at.

The PSS System is a dripless, maintenance-free, stuffing box replacement unit.

My PSS stainless rotor has two opposing AWAB hose clamps on the shaft in front of it as a "just in case" so even if the set screws were to come loose it would not move..... You should REPLACE the set screws not just re-tighten them. PSS will ship you the proper type of set screw for very little money... Also the set screws should be "stacked" meaning two in each hole with the top one preventing the bottom one from backing off...

Simon,

Isn't there a stainless steel wire going through both set screws to prevent them from backing out? Check to see if the set screws have a little hole in them.

Thanks halekai36, I like that idea, and will do it . But what do you mean by opposing hose clamps? Is it a balance thing?

Denby, I have no idea, at the time I was more interested in stopping the ingress of salt water. I will look tomorrow.
