Yanmar SD 20 Dog Clutches

Has anyone had experience with replacing the clutches in Yanmar SD20's?
I have one SD with no forward or reverse (evenusing the lever on the transmission)
and the other is losing reverse.

I have never worked on one pesonally...but from what I have read proper lubrication is very important....Since you have had no replies...I would suggest you get a shop manual....I tried to find one on-line but no luck...Maybe Gordo has one in his "Archives"

What ever happened with your shifting problem?? I'm having trouble shifting mine into forward.
