New fanimold gaskets required?

Yes, and the faces aren't totally flat any more. Apparently this is moderately common due to the thing being the length it is.

I may put a straight edge to it, and possibly even a file. We'll see. I would prefer to get it machined but that may not be an option locally.

I applied fire. This was not enough.

Both damn bolts broke off so I drilled them out.

Cleaned the threads up with a tap.

Result, a threaded hole.

Repeat.

 

The exhaust manifold is much harder metal and proving difficult, I've had to drill one hole oversize so I'll have to drill the massive big holes through the intake out a size too.

Hopefully this works. If not, I have had someone offer me a manifold...

Was working tapping the first hole, drilling the second. Decided on a change of pace after dinner so grabbed the manual for the alternator and took it to bits.

The diode trio (the little orange bit) is bad. The rectifier pack is good, the capacitor good. Brushes are fine (held in their case with a piece of wire in that picture).

 

Hopefully replacing that will remedy the problem. If not, the regulator pack may need replacement (white plastic piece).

The bolt through will work, I think. Also have a lead on a table sander so I may be able to get the manifold back to being flat again- there is a slight warp between the ends and the centre of the exhaust manifold so no matter what, it'll end up leaking if I don't get it at least a little more flat.

Even the new stuff is imperial because America has too much of a stranglehold on aviation- plus, if you fly around and land somewhere with a broken piece the last thing you want to be told is they can't fix it because it's got the wrong type of threads.

Boeing naturally, but do Airbus really use unified threads?
