  • Description

    As with any rubber/silicone hose below the waterline, the PSS PRO bellows must be inspected on a regular basis for any signs of wear, aging, or chemical deterioration. PYI suggests preventative maintenance with a precautionary replacement recommendation in 8-10 year intervals. During bellow replacement, it is recommended that the o-rings & set screws in the stainless steel rotor also be replaced.

    Please be sure to never use the same set screw on the shaft twice. There are two set screws in each of the two holes in the stainless steel rotor. One is tightened onto the shaft and the other is tightened onto the first to lock it in place against the shaft. The set screws are made with a cup at the base that compresses into the shaft ensuring a secure grip. PYI's PSS Maintenance Kit comes with five new set screws included. When re-installing the rotor please use new set screws. In the case that you do not have spare set screws, the set screws in the rotor need to be reversed so there is an unused cup being compressed onto the shaft.

How Does It Work?

1. Two nitrile o-rings seal the stainless steel rotor to the shaft and will not experience wear.

2. The Shaft Retention Collar is attached to the shaft and helps retain the propeller or rudder shaft in your vessel in the event of catastrophic failure of the coupling or if the shaft comes free from the coupling.

3. A seal is created between the two mating faces of the carbon stator and the stainless steel rotor.

4. A seal is created between the two mating faces of the carbon stator and the stainless steel rotor.

5. Raw water is fed to the PSS Shaft Seal for cooling / lubricating the seal faces on high speed vessels.

6. Hose clamp tail protection, Clamp Jackets.

7. The stationary carbon stator is attached to the bellows, which is secured to the stern tube (shaft log).

8. 316SS hose clamps with rolled edges and non-perforated band.

New shaft seal bellows.

Since we were hauled out for other preventative maintenance, and I had no record of when the shaft seal had last been serviced, I chose to replace the bellows. Hardest part of the job was getting the shaft coupler off, after than it was simple and easy to remove the stainless rotor collar, carbon disc, remove and replace the bellows, and reassemble the whole thing. Parts were shipped quickly too, had them in plenty of time.
