Rudder stock bearing service


Recommended Posts

Does anyone have some insight into how I can service/inspect this without the rudder dropping into the Westhaven mud?

 

Underneath I have a nipple for the bottom bearings, but nothing for the top. Underneath is just a fibreglass tube going from top to bottom with a nipple at the top attached to a flexible bit of hose that seems to go to the bottom bearings only as evidenced by grease commming out the bottom after filling it up.

 

It started to squeak a bit on the way home from White Island so I think I need to do something about it.

 

Thanks

Rudder bearings are often water lubed. Depends what it’s made of, there are quite a few systems.  No option but to get it out and take a look. Can be done in the water if you’re CERTAIN that the rudder tube goes right thru, and the boat won’t take on water...

100% certain, the tube is uninterrupted from hull to deck.

 

So what's the process? There's obviously a big hexagonal thing at the top, infact apart from the four screws in the photo there is nothing else...

 

What stops the rudder hitting the mud if I undo that nut? Does the rudder have to be supported first?

Ours was un-caged plastic rollers (well something hard that looked like plastic)

My cousin and I dropped the rudder on the hard at GH, nice clean tarmac.

And we lost one roller...........

Couldn't find it anywhere, so frustrating.

 

Later I got a message from my cousin that he had found it in his shirt pocket.

 

Be careful if you do it in the mud.
