Steering Cable Sheave Bearing??

I just had the rudder dropped to have the shaft shortened and a new cutlass bearing installed, so the steering cables/quadrant are already removed.

The bronze steering cable sheaves (that turn the cable 90 degrees from the pedestal to the quadrant) seem a little wobbly, so I want to change out the bearings.

Bearing seems to be about .561" OD and .435" ID and 1/2" wide, but I don't know what the original ID would have been. Has anyone replaced these, and where did you get the bearings? Sheave dia is 4" with an Edson Steering Column.

Mine seemed a little wobbly too. Mine did not appear to have a bearing. It appeard that the bronz pully was the bearing. I greased the hell out of them and they appeared to work well. I think you need to replace the pully. Edson would be my guess.

Hmm, on mine the bearing is visible in the second photo, pushed about 3/4 of the way out. It removes easily. Maybe it's a Yacht Specialties steering pedestal--where does it say?

Note that you can slightly enlarge the hole by precision boring and then press in a "oiled bronze" bearing. That was done to our sheaves.

I believe that any machine shop could do this. Lathe and press would be needed. Our sheaves were done by a friend with a home machine shop.
You might ask around at nearby boat yards and chandlers.

Being a 85 model most likely a Yacht Specialties pedestal originally. Check the nut that holds the wheel on for a "YS" on the face.

Bearings can be purchased through Mc Master-Carr. If you have a vise and a socket, with an ID just slightly larger then the bearing OD, you can press the old ones out and install the new at the same time. No need for a machine shop.

I would ask Edson if this is from an Edson helm.

I have been impressed with their customer service. They probably have the right part in stock.

My boat, with Yacht Specialty/Merriman gear, seems to have simple bronze bushing inserts in the sheaves. They just press in by hand. The former owner changed them, and left me a couple of spares. Could well be a standard size. Grease is to be applied.

Yeah, you gotta love McMaster-Carr for pretty much any piece of hardware you might ever need--ever.

Follow up: Per the Ericson manual, these sheaves are called "steering cable idler sheaves," and the pedestal is from Yacht Specialties. The bearings are replaceable and available from McMaster-Carr. Looking at the McM-C website made it pretty clear which bearings I needed (i.e., these were not some specialty part built for Ericson in 1985), they are sold in common sizes. The measurements I came up with originally (.561" OD and .435" ID and 1/2" wide) were pretty much right on for a 9/16 (.5625) by 7/16 (.4375) by 1/2" oiled bronze bearing. At $2.60 each and $8.00 shipping, McM-D had them on my doorstep in 2 days.

While the old bearings slid out easily, the new ones were too tight to put in by hand (and, I hadn't read about your vice trick yet). I sanded a slight beveled edge on one side of each of the bearings, rinsed them clean, and put them in the freezer. I heated the sheaves on the stove, oiled the openings, and tapped the bearings in place with a plastic-head hammer.

While it's still not a tightly-toleranced fit, I'd say there's about half as much play in the sheave now compared to the old bearings. Well worth the $15 while I had the quadrant apart.
