Trevor, in my reply to "Chuck" I said he should have allowed the posts but added his own comments.
Simon, I think your comments are all too true.
The only possible option for parts offered by the "Marine Electronics" specialist suggested by Raymarine themselves was the possibility of a complete new motor, ram shaft assembly, costing in excess of £300.
You can see the cheap little Chinese motor here in this photo. You can buy one on Ebay, type number is RS 555SH.
On the outer end of the ram there is a silly little spring clip retainer. I have never seen these used in an application where reliability is paramount.
The main ram shaft end seal does not have an anti magnetic garter spring, it is positioned less than 2 inches from the compass, proper marine grade stainless is anti magnetic. It may be a cheaper type of stainless so if it fits I will reuse it in the new seal just in case it is less prone to attack by salt water, this one looks in good condition but the seal lip does have some wear which is why I am replacing it.
I ordered these for a replacement seal.
and this for a replacement "O" ring seal to go in the main seal housing.
I forgot to mention the "O" rings used for the end of travel buffers were 6mm x 2.5mm o rings I happened to have in my kit.
I hope this thread can help someone else when they suffer the same failure.
I have added images for the items as web pages tend to disappear.
I have not finished and tested the repair but I dont expect any problems. I will update after this weekends sailing.
