Help reuired with a stern gland (WATER COOLED I THINK??)

[Pye_End]

I cannot scan, but I can say that in the BZ482 manual it is on page 24, with a WARNING sign next to it.

I have also found on page 25 that 'if water is required for stern tube lubrication then this should be taken from a T piece in the pipe going from the heat exchanger outlet.

I would imagine that water from a heat exchanger system is relatively cool compared with a direct cooling system. No idea what the water temperature gets up to, but my exhaust pipes run cold compared with the 1GM10 tht came out.

Re: Help required with a stern gland (THAT LEAK! CONTD.)

Blimey, have I moved on this much??? But thanks to posts and PM's and e-mails I now know I have a PSS NOT DSS (nor the American import either) water-lubricated stern gland. Early models needed squeezing when you dry out but later versions come with a down tube from the exhaust.

Water drops - gravity, not vacuum - and lubricates the plates. Maintenance-free UNTIL something wears out - check bellows for flexibility.

Sound familiar? I hope so.

And to those who uttered dire warnings, I respect your preference for turning the screw and filling the bilge with old grease and seawater from the inevitable drip but am sticking with mine even if a bit of crud broke the seal and caused a mini panic. (Mini? Hah!)
You see, on two previous boats I had no problems at all with similar seals.

If you can't identify your particular piece of kit then PM me.

Thinks, from ignoramus to expert in 3 weeks thanks to YBW FORUMS!

You can find the items in the Vetus catalogue:
www.vetus.nl
Look under "propeller shaft". You might also apply to for an excellent booklet they produce ... or used to produce ... that was called (in Dutch) "Around the engine". It has/had clear and graphic proposals for engine/shaft/exhaust setups.
The waterlubricated glands start from diam. 35 mm upwards, and have a code ZWB35, ZWB40, etc (they use mnemonic catalogue numbers! ZWB= zwevend binnenlager= inner gland).
