Description

As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration. PYI suggests preventative maintenance. The PSS bellow should be replaced in six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced.

Bellows may need to be more frequently inspected in an environment where non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.

NEVER USE SET SCREWS MORE THAN ONCE!

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.

Ive dealt with PYI with both my max prop classic and PSS shaft seal. Expert advice, incredible team of people, fast shipping. Top notch service. Cant say enough good things about dealing with this company.

Excellent service

When placing this order I made a mistake on one of the items and they had the forethought to call me and verify that item and we were able to correct it on the fly. The service was excellent and these parts go into my spare parts bin for the future.
