Pedestal Steering Clunk!

[Delancey]

Trying to help a friend fix a clunk in his pedestal steering. The pedestal is Yacht Specialities Co. which I understand was owned by Teleflex before going under in 1989.

The problem is a clunk noise and associated jarring that happens when the rudder swings to its limit on either side. A problem that was noticed after someone with a heavy hand had been driving and possibly damaged it.

Not sure what to make of it. I wonder if the attachment from wire rope to the chain is catching on something? Any insight would be most appreciated.

check that the cable is tight. It could be that the cable is walking around on the sheaves or over-wrapping itself on the sector. Also, the chain might not be held tightly into the steering sprocket. Also, look for the cable ends. Are they fouling on anything? Also possible that a sheave bearing is bad. Have someone get close while it is cycled.

Here's a .pdf of an installation manual that might be your friend's model:

Parts aren't likely to be available but a quick look makes me think I could repair/remake/repurpose parts that might be needed. There will be people near you who can do the same, just a case of finding them.

Quite a few results for "yacht specialities co. steering"
Quadrant stop seems to have been an issue.

Good luck!

Check cable tension. Cable could have slackened and now hitting stop on quadrant harder than before .

Looks like we will be replacing the rotten rudder stop. Eased tension on the cables to confirm it wasn't beating related, found the rotten wood. Thanks for the link to the manual!
