What did you do with your old SD50? Would you be willing to sell parts?

Hallo all,
I had my cone (H400 2007) replaced after appr. 500 hrs and was approaching a new overhaul. For insurance purposes I also need to change the saildrive seal in the not to far away future.
The  decision to change to the SD60 became obvious after extra guidance from Yanmar as how to handle the SD50. For instance:
1. shifting gear with prudence in order to reduce slippingAngry (Better not to shift at all)
2. while motorsailing constant awareness that the sail is not giving more pressure than the motor, especially at the moments of setting sail.Angry (Why on earth should you set sail with a sailboat)
3. not having the gear engaged during sailing.Confused
The first two are imho basic needs that a saildrive should be able to cope with. As I am planning for some longer trips in the near future I decided to invest. Supported with a discount of 10 % by Yanmar and some refund for the old saildrive by the dealer.
The job has been done by a yacht service company and Yanmar dealer familiar with Hanse yachts. Besides better responses while shifting it also resulted in much less noise end less vibration.SmileClap
Grtz. Wilko

Many thanks to everybody for really good instructions!

I lapped the clucth cones about a week ago and the clutch seems to work now perfectly. I started the work at 9.30 in the morning and had the clutch disassembled by lunch time. Had a good lunch in an Italian restaurant (no wine, only San Pellegrino). In the afternoon I started lapping. It was somewhat difficult for me to determine when the surfaces were matt. To be on the safe side, I turned the cones about 20 times back and forth. By 5 o'clock the job was done. By my experience I can recommend to anybody capable of keeping simple tools in hands to do the lapping.

Regards,
Heikki

Hello all,

Recently I have had the clutch cones lapped by a friend who happens to be a retired Yanmar dealer. He found no sign of wear and rear on the parts in the clutch. He did find that the vertical movement in the system was too large. Yanmar specs call for a "gap" of 0,05 to 0,55mm. Factor 10?! In mine the gap was even 0.60mm! As he said the whole system was rattling around.
A new ring (shin washer?) was made to reduce the gap to 0,06mm. The system works perfectly now and according to my friend is better than new.

Cheers, Wijnand.

Kymo,

Interesting, but not sure if I got it right?
Is this vertical movement within the unit that is pulled out of the saildrive to service the clutch cone? So the movement can be checked prior to loosening the end nut?
