Hi PASO lovers. To make a short story long. For about a month ago, I was a bit unlucky with my clutch piston bearing, it completely broke down and the piston turned in the slave cylinder making some nasty grooves. I bought a new bearing, thinking that I would be able to get the dam bearing out of the piston. This turned out to be a challenge and a complete a disaster and I had to give up and purchase or rather order a new piston with bearing, o ring, pin and spring. After a couple of weeks my PASO pusher had it on the desk and I quickly inserted it. After the first test drive the clutch felt very strange, and I suspected that the slave cylinder had been damage after the piston had rotated, even thou I had polished the cylinder with fin sandpaper and gotten rid of the groves. To the end the clutch completely lost pressure. I have been looking desperately after a new clutch cover, and in the mean time I have been so lucky to borrow a cover. And now the interesting part starts. I installed the cover and it worked fin for a couple of hours and then the clutch lost pressure over night. Now I was getting a bit aggravated. When I dismantle the cover I could se that the slave was leaking. I pulled out the piston and could see that there now damages to the cylinder or the piston or the o ring. I then got a bit suspicious of the o ring and I still had the old one, and I measured the damn things. It turns out that the new o- ring has an outer diameter of 25 mm, and the ring itself is 3,1 mm. the old one is 26 mm and its ring is 3,5 mm. So I then put the old o-ring on the new piston and it works fin so far. So when purchasing a new slave piston set, get a bigger o-ring, one like the old one because the new is o small.
