348 Clutch Replacement Part 2 Replacing the Triple Seals

Chances are that you will need a new set of O-ring seals.
Although it might not be stricktly necessary, but its a good idea to replace them while you're in there.

Tip:Clean and check the shaft for scores, also check for any leakage of the clutch fluid (same as brake fluid).

1. Gently pull out the inner shaft until the triple seals become visible (pic#1), cut off the existing seals and clean the shaft and grooves.

2. The inner O-ring can be removed for installing a new one, you also need to remove the steel ring in order to fit the new triple seal rings (pics#2-3-4).
In pic#4 you'll see a new inner O-ring installed.

3. Now the tricky part, the triple seals are an interference fit on the shaft and require immersing in boiling water for about 5 minutes (pic#5). This will allow the seals to expand just enough to slide them over the shaft and into their grooves. Once the seals have cooled down they'll return to normal size and become a snug fit, allowing to push the shaft back in (pic#6).

Tip: If the seals WONT shrink fully then make sure they are in their grooves correctly.
This is why its important to clean the shaft and grooves before installing the new seals. Tapping VERY GENTLY on the end of the shaft should allow you to push it back in. (pic#7)
