Build Day Twenty Six - Exhaust

Unlike the title of the blog suggests, it was more like a build hour today... There aren't many more jobs that I can finish before it gets collected on monday.  So I fitted the catalytic converter and the exhaust.

First job was to screw in the lambda probe into the cat.

The cat was then fitted to the exhaust manifold outlets, then rested in place as per the instructions, and the exhaust manifold bolts were torqued to 34nm on the engine block.

Next job - getting the springs compressed over the mounts to secure the catalytic converter.  After fiddling around trying to get the springs over with various pliers, long screwdrivers and so on, the best solution I could think of was to compress the spring using tie wraps.  Worked a treat, the tie wraps held the springs in a compressed state and then it was easy to get the springs onto their hooks.

Then onto the catalytic converter protector.  A simple job of opening up some oversized jubilee clips, threading them through the mounts on the inside of the protector, and then securing them in place.

Finally a quick fit of the exhaust bracket and then the exhaust was on.

That's it for now, like I said above tomorrow will be a day of finishing off any odd jobs that I can, and then it'll be collected by Caterham on Monday for the Post Build Check, IVA and registration.
