The split ring I have from Jefa would fit in there
Or try this site http://www.beltingonline.com/locking-bushes-collars-738/double-split-shaft-collars-938/metric-stainless-940/ beltingonline if you cannot get the link Not a bad price or if you try bearing boys at http://www.bearingboys.co.uk/CASB50Z_-_50mm_Single_Split_Shaft_Collar-40341-p you could get one for just over £10-00 but would have to drop the rudder a few inches Edited by samuel - 16 November 2014 at 18:28 |

Thank you Samuel,
for your info and links.  Now that I know the right english name for that part, it's easy to find plenty of them in internet. Or maybe I make one with a 3D printer at work, we'll see. And still waiting for a reply from Jefa.

I received a reply from Jefa on Sunday (!). According to them I've got two options, a locking ring under the top bearing or between the rudder blade and the lower bearing. Both solutions will require a delrin/teflon washer for a smooth movement.
A standard locking ring will not fit under the top bearing unless I lower the whole rudder. That means a wider gap between the top corner of the rudder blade's leading edge and the hull. Maybe I'll go for a tailormade, "slimline" locking ring.

Re the delrin washer
You could split the washer on one side &spring it onto the shaft. It does not take a great load so will not distort Buy 2 washers to save carriage cost & if it does not last long you have a spare ready If it fell out mid season it would be no great deal. When i changed my rudder i found mine had never been fitted. All that happened was that the ring & bearing housing were very slightly scored. A smear of grease would have solved that |

Hi Just a little update, the work is completed in our case, the missing ring is now installed and the rudder can't push against the hull anymore. Attach picture before and after. You find the product in www.jefa.com IF anyone would like to do the same. ""WASBA035-055 Washer with ball track 35 mm to 55 mm "" In our case (H400) 50 mm.

Thank you all for your inputs. Launching day closing (still eight weeks to go) and it's time to start the preparations. I finally decided to go for a 50mm x 16mm split shaft collar and a teflon washer to keep the rudder down. It is an easy (and unexpensive) solution, without the need of removing the rudder. We'll see how it goes. If there is too much friction (even for just cruising), then I'll update it with Jefa's washer with ball track. The first spring day is here, +8 C, sun shine ... |

Hello, looking at the picture of the rudderblade I see some damage to your boat. The rudder is grining to your hull. You need to put 2 plastic rings on your ruddershaft. These rings are specially designed for your blade/boat by Jefa, call them and they send you those rings. Officially these rings are put in place by the production of your boat. But it is a production in line boat, they forgot to place the rings

Hmmmm, i am worried now......
1. I know the rudder can float (look at Johans video) 2. My rudder never touched my hull so far. 3. But, the shown washer is missing on my boat aswell, maybe as on many Hanses. So why doesn´t my rudder push upwards? Or why do some rudders push upwards and some not..... I never had any problems with it. So i think, i will not change a running system. |
