I'm a plant engineer and our maintenance shop has just about every kind of Oring. If not, it's off to McMasterCarr
Search and buy a "oring 2093" "Viton" or "NBR" (no other materials) A oring 2093 matches with 23,52X1,78 millimeters http://www.thisoldtractor.com/o-rings_uni.html
Hydraulic oil Arnica 32 is nowhere to be found in small packs. But finally i found a good mineral hydraulic oil SAE 10 alternatively
Just checked the fluid level in the clutch reservoir today, still was full and no loss noticed since I filled it about five months and 1400 miles ago. The bike had about 8100 miles on it when I noticed the reservoir was almost empty. Bought the bike a little over one year ago when it had about 4,900 miles on it so I don't know if the clutch fluid had every been changed or added to. I used SAE 10 mineral oil (fork oil). Will order the o-ring for the lower piston soon when I will also be ordering an o-ring for the main drive shaft (bike leaks a little oil from behind the front sprocket).
View: https://m.youtube.com/watch?v=eJXLR5w1ADU Today I did a test to see the quality of the original o'ring husqvarna . and ' older than 6 years and he has 85 hours of operation This flotation means that has become porous and therefore is not able to function .
