Goïot steering - bearing replacement

[knuterikt]

On my Beneteau First 38 from 1984, it's equiped with a steering pedestal from Goïot

Picture of wheel with logo

I have some questions
How much play is normal on this steering?
When the breake turned back a little bit there is almost no play in the wheel.
If I turn the breake all the way towards the wheel I get aproximately 1 cm play at the rim of the wheel, is this normal?

I have tried to contact Goïot and navimo to get hold of documentation but the don't bother to answer..
Does anyone know how to take this appart to replace the bearings?

I had the compass off last year when I replaced the steering wires and lubricated the chain.
I'm wondering if there is a locking pin for the chain sprocket that also keep the shaft in place.

Tighten the wires, there must be some stretch in them since installation

Do you mean 1cm fore/aft play in the wheel or radial play? If fore/aft at the rim but not at the hub then I would support your thought that the bearings are on the way out. My benne only a year younger with the same pedestal and wheel has very little wheel 'wobble'. My wheel does move in and out about 1/2 cm but it does need 'ooching' to get it to do it. It had a bit more radial play until I adjusted the steering cables but thats now gone.

It's not the wires - Replaced and adjusted last year.
When I take the brake all the way off - I can lift the rim of the wheel upwards 1 cm.
If I tighten the brake so that I can feel a little friction the play i almost 0

The chain goes over the sprocket, by tightening the wires that pulls the sprocket down & reduces the movement

It seems to be fixed in the for & aft direction.
It's the up&down or side to side direction I have play.
When i tighten the break the wheel is centered and there is no play. The more I undo the break the more play I get. Max play when brake is all backed off is 1 cm measured at the rim of the wheel (up and down).

I'm wondering if this is as designed or if it's a sign of wear in the aft bearing (pos 4). Don't think that is has changed much in the 6 years we have owned the boat.

If I knew how this thing was assembled I would take it apart to inspect the bearings.
Found this in http://www.goiot.com/bdd/pdf/53.pdf
Looks very similar to what I have, My French is not so good could it be that part no 12 is locking the whole assembly in place?

 

[nimbusgb]

That does sound like a lot. Tempting to take it all apart I'm sure. I think the sprocket is keyed or pinned onto the main shaft which keeps the lot in place. If you do strip it and replace the bearings I'd like to hear what replacement part you use for future reference. They will be metric coming from Goiot so should be simple to source.

BTW I modified my hub with a quick release mechanism so that i can remove the wheel when not sailing.

The brake clamps the spindle so it cant move.
how long since you installed the new wires as new wire stretch.
what happens if you move the wheel quickly & stop, can you feel the rudder wobble

Have no problem with wobbly steering.
Sounds like the wrong medicine to (over)tighten the wires to restrict play in the bearings?

keep us posted when you nail it

Thanks had to register to get access to the large pics and pdf.

I would like to modify hub with a quick release, Could you please advise how you did it.

We pulled the steering assembly apart this weekend, I'm glad i didn't tighten the wire to fix it....

It was a pin holding the shaft and the rest in place.

The bearing totally worn out

Need to source new bearings...

I thought they might just be plastic bearings, because although there is little play in the ones on my Jeanneau 45.2 there is a tendancy for the one on the port side to squeak. Goiot spares appear difficult to get, but as you can measure the shaft and the hole the bearing fits it should not be too hard to make new bearings. As for material PTFE rod is probably a good choice, though Delrin is another possibility. Nylon tends to swell when wet so is probably best avoided for this purpose.

Looks to me like the parts 3 and 4 (coussinyl) are nylon bearings which would allow play if worn. I think part 12 (goupille inox) is a s/s key or pin holding the shaft in place. Your local Beneteau agent should be able to order these bearings from the manufacturer.

Goiot Steering Hub Plastic Bearings

You should be able to find suitable parts by using a micrometer to measure shaft and openings, then go to http://www.igus.com/iPro/iPro_02_0001_0000_USen.htm?c=US&l=en and find the appropriate sized flange bearing for your particular Goiot system. You might need to cut the bearing to length, the ID and OD are the most critical ... QED.

We found a solution, but your link might help others with the same problem
Checked several local suppliers, problem was the thin wall thickness on the original part - only 1mm. We found parts with wall thickness of 1.5mm
We got some with correct ID but over sized OD and managed to adjust the diameter using a lathe and fine emery cloth.

An alternative could have been to increase the diameter in the pedestal to fit the larger OD, but we didn't look into that.

Hello Knuterikt
I have a Kirie feeling 1350 my selv equipped with at Goiot pedestal. You say, that you took the compass off the pedestal. I have a Marco Polo compass on my boat and I cant figure out, how to dismount it. Can you tell me how you succeded?

We don't have the original compass any more - it was replaced with a new one (and I do think it was another brand than Marco Polo).

From memory.
There is a plastic ring at the top, this is snapped on - take this off.
The compass bowl is attached with some screws, remove and lift bowl out.
The compass housing is screwed to the top of the pedestal on the inside, you get access when compass bowl is removed.
