My new parts arrived the other day. Time to rebuild the clutch cylinders. First I filled a small cup with brake fluid and soaked the parts in it. This made the rubber pieces more pliable and easier to slide over the metal pieces. Especially when it came time to install the piston back in the slave cylinder, you have to press the cup in all the way around and make sure to keep it very straight as you insert it. The piston in the master cylinder was almost as much fun. It’s very spring loaded, and you have to press it down to install the washer and circlip. This would be a good time to ask a friend to lend a 3rd hand.
Well, my epoxy sight glass seems to have come out ok. If it doesn’t leak, or react to the hydraulic fluid it should be ok.
