Title: replacing donuts...
Post by: jzap on September 23, 2008, 08:30:40 PM
On my 96 Tracker, the joint between the exhaust pipe flange and the catalytic converter is spring loaded.  Two long bolts thread into the flange on the exhaust pipe, and the joint is held together by springs on the bolts. 

Does anybody know if there is enough play in the joint to be able to pry it apart and remove and replace the donut gasket inside the joint?

No that is not possible! What is wrong with just unbolting it and replacing the gasket like normal people!LOL!

Typical...  bolt ends fused into solid mass of rust...

Guess its break em off, drill em out and retap???

So, Why is the joint spring loaded and not bolted down solid?

Blue-tip wrench.  ;D

It is a high vibration version of a lock nut.

They're usually not very tight, the spring holds the pressure. Take a wire brush to them and give it a go. If you do drill, you don't need to tap, just drill the hole big enough so the nut is gone, and buy new spring bolts - they usually come with nuts, then use a big washer :D

or just heat and let cool then you may not have to ruin the nuts if possible

The joint is flexable to allow movement between engine and exhaust system. Ever watched your motor move around when you juce the throttle?




So, Why is the joint spring loaded and not bolted down solid?
Also, it allows for different expansion rates between the various exhaust components as they heat up and cool down.
