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.

New Seals

Originally ordered maintenance kits but after further inspection of the rotors and graphite flange on my boat needed to be replaced. PYI Representative Eric Young was very helpful in selecting new seals. Delivery was prompt. Thank you. Alan.

Good service, fast response, and support

Replacement Bellows

The kit was as described and arrived on time.

My products arrived in a timely manner despite X-mas rush. no damage and packed well. Looking fwd. to hanging upside down to install shaft kits . . .

Outstanding

After I pressed go on an online order, I called with a question. The staff at PYI answered all my questions, were able to determine which maintenance kit I needed based on the outside dia of the bellows, and intercept my order and and toss in some recommended sleeves. Seals are updated and I am dripless again.
