Dripless shafts

Hmmmm. Which brand of dripless shaft seals?

Sounds like PSS. Sometimes you get dirt in the face seal and as J suggested it can be cleared. Also make sure the seal isnt loose and thwt there is enough pressure from the bellows

What do you mean by move the bellows? Compressing them or moving sideways? If compressing how much?
If moving bellows where is the water coming in?

Cleaning the PSS is crudely explained here;


The shaft log hose is the bellows refereed to. It has an spiral spring in it that keeps pressure against the stainless ring.
If cleaning and polishing the contact surfaces does not stop the leaks, loosening the steel collar and applying more pressure to the bellows may correct some last leaks.
Mark the position of the collar on the shaft with a Sharpie or tape.
There usually are two allen screws per hole, remove the outer screw and just loosen the inner screw a half turn.
By hand or with a small block of wood, lightly tap evenly (around the shaft) the steel collar aft 1/4".
Snug allen screws, verify just 1/4" movement, tighten allen screws, install locking allen screws and pour a cold one.

You don't want to get carried aweigh with to much pressure, small adjustments at a time. If you end up applying over an inch of adjustment against the bellows, something is wrong.

There is not a lot of pressure against the ring.
Supper flat & clean surfaces. The water acts like the sealant and lube. To much pressure; the water may not evenly coat the surfaces.
Do you have any idea how old the system is? PYI recommends replacing the bellows every 5-6 years. They could get stiff.

Check out the install video to get an idea how these work.

The small hose on top (5/15 to 3/8") is for raw water from your engine to ensure water is injected just behind the contact surfaces of the shaft seal.
This small hose does get restricted or clogged. Always good to check it when servicing the engines raw water pump impeller.

Brass is not suitable here. Marlon and Bronze are not available in this small size.
Sadly, that just leaves nylon. Brittle and low melting temp, it does need to be looked after.
I find that when people step on or pull on the hose, this light plastic fitting takes the abuse and fails.
Replacement should be easy to find at Home D.
BTW, a poorly installed hose my cause some weight to be applied to the log seal and keep it from sitting correctly.

Take the hose off, start engine. Ensure water comes from the hose.
Make sure water leaks in from the shaft seal thru this lil fitting. If not, correct.
