Packingless stuffung box?
 

Sorry If I posted this twice I got an error message:
Here goes again.

Last night a friend came in with his bilges flooded. His float switch
to his bilge pump was floating. I helped him pump out his bilge and
found that he had one of those packing/stuffing boxed that do not use
packing.

Ive never used or worked on this type of system, but looking at it
here is how i figure they work. The tube is flexable and like a spring
that pushes a machined flange against a flange that is on the shaft.
Looks like the part attached to his shaft moved forward and it looked
like a full speed garden hose type flow coming out of the gap between
the two flanges. I loosened the flange on the shaft and smaked it back
with a sledge hammer after applying grease to the flat surface and
that stopped the flow.

Questions:

1. the flat area/flange attached to the tube seemed to have lots of
play side to side/ up and down. Is this normal when it is loose? I
would think the I.D. of the tube flange would be alot tighter.

2. Is that how they work, just pressure from the spring type load
applied by the accordian type tube pressing the two machined surfaces
together? Or has something happened to the system and is now missing?

3. I noticed on top of the shaft tube was a smaller tube that was
capped. Is that suppose to be a grease zert that had been removed in
the past for filling the tube with grease?

Myself I like the tried and proven packing type gland and feel this
new fangle system is just to funky. Does anyone else use this type of
system and like it?

Thanks
Joe

I know you're NOT supposed to put any grease on the machined surfaces.

Nope. That's to let air out when you launch the boat.

"Trains are a winter sport"

The 'other tube with a cap' is to 'burp' the seal. Water pressure
helps the bellows to push the seals together.

Look at this site:

Do not use grease or oil to slide the stainless steel rotor down the
shaft.
Do not allow foreign material such as lubricants or petroleum based
antifreeze to come in contact with face of seal.
Install the P.S.S. only when the boat is out of the water
Do not damage the carbon flange or stainless steel rotor while
unpacking and handling.
Do not re-use cupped point set crews. If the cupped point has been
flattened replace screws.
Do not replace nylon hose barb fitting with stainless or brass.
Do not use a ozone generating device around the PSS Shaft Seal it can
cause irreparable damage and failure to the rubber bellow.
