Re: stiff steering

Sorry, can't leave this alone. It looks like there is a rounded gouge above that drag link. Was this put there at the beginning so the link would clear, or did the link create this gouge over time?

Re: stiff steering

The cut-out above has been there for the 10 years we have owned the boat so nothing new that I am aware of. However, there is a very small but real nick from the top of the drive unit on the rudder connection point that hits when the rudder is fully to port. Under load I wonder if this has created some issue?? Good question Mark.

So my next steps are to segregate where the noise is coming from: steering pedestal, rod to rudder, drive unit, rudder by removing each one at a time.

Nonetheless, if anyone who owns the equivalent PSC 37 and Whitlock/B&G steering equipment as I have can suggest every lubrication point in the steering system, and with what they lubricate it with, it would be very helpful. I just feel I must be missing something or am not applying the right lubricant. The system works wonderfully besides the noise and stiffness.

Re: stiff steering

I have a PSC 34 with a wheel pilot, so a slightly different setup, but the design of the quadrant and rudder is exactly the same. The binnacle is from Edson. Two years ago I started getting a squeeky noise from the rudder. After injecting waterproof grease in the gudgeon that noise went away. It's probably not the same noise you're getting, but it's not a bad idea to keep the gudgeon greased.

There is a small hole at the bottom of the gudgeon that you can squirt grease into with a grease gun. Initially it won't do much, but the grease will eventually work its way down the shaft lubricating it.

Re: stiff steering

If this is a problem only when underway, you could mount a GoPro to watch suspect areas. It will probably even pick up you yelling from above in the vid, when you identify it happening, so you can see if the suspect area is doing anything unique.

Start a stopwatch on your phone (or just take note of time), when you start the GoPro, so you can more easily fast forward to the segments you want to watch.

Re: stiff steering

Is this the gudgeon (red arrow pointing to it). If so, approximately where is the small hole I can add lubricant to?

Re: stiff steering

I'm not at all familiar with this (Hydraulic) system BUT, I would assume when not activated all hydraulics would need to bypass, is that what the solenoid valve in the picture does? I have the same drag link setup as you without auto pilot and the mechanical part is pretty bulletproof. Maybe a quick check of the connections to the solenoid, I don't recall did you say autopilot operation is smooth? Disconnecting the entire Hydraulic ram would be the next step but I don't understand why it wouldn't show the same symptoms with E-tiller in operation, Its the same motion as turning the wheel except you are freewheeling the wheel with the tiller not driving it, but you inspected and lubricated that first. Are you testing under way or at the dock.

Re: stiff steering

Sorry, this is not a picture of a solenoid valve, it is a diagram of my rudder.

Given all the great sailnet.com input I am pretty sure I am dealing with a "where do I grease" the steering/rudder system problem and not much else. I am hoping someone with a similar PSC configuration can recommend where grease is required.
