Volks, Does anyone have a picture or description of how the 2.1 exhaust system donut gaskets hardware as it was originally installed? I looked at the Bentley manual, and ETKA and found that the forward end of the connector pipe (where it meets the Y cast elbow) is supposed to have 65mm long bolts, 5 spring washers and 1 thick flat washer and a high-temp lock-nut. The 5 spring washers are called diaphragm washers , also known as Belleville washers, which are basically cupped steel washers. I need to know if the cups all nest together in a short stack or alternate against each other in a long stack. The lock-nut obviously must have a specific torque and along with the spring washers, will this maintain a snug fit that can flex by use of a steady clamping force on the donuts and pipe flares. The Bentley does not specify a torque value, so I'm assuming standard torque values. I'm not interested in hearing how no-one ever does this and how yours has been just fine without the spring washers. I'm looking for the correct information, so I can set mine up exactly the way that the factory engineered it. I've experienced multiple joint failures due to them being assembled for years without these spring washers. Now that I know why it's not lasting and have new parts, I want to do it right, as original. Thanks for any assistance. Mike B. |
