The Gen3 runs on minimum vacuum, so the painted one was dialed all the way in, and the rest sync'd to it. If you can, then great....

Depends where the sync was before you removed all the screws... in some cases the reference changed or Yamaha didn't have it right in the first place...... if you couldn't sync one of the screws and had that one dialed all the way in as well..... in that case, the second one becomes the reference and you back all the others out to sync. But, you always have one screw all the way in.

Next weekend I'll grab both of my Morgan's and take them to the Metrology Lab I manage at the nuke plant. There I can perform quantitative testing with NIST traceable standards to determine, within 3 sigma, the sensitivity value of each of the 8 channels. Not kidding

While I'm at it, I'll determine accuracy too!

Edit - this will have to be static testing. Can't replicate dynamic conditions.

Did you ever?

"applied appropriate suckage" lol


Good luck getting anything dialed in with dirty throttle bodies and injectors.

Here's a blast from the past. I used to use a set of 4 vacuum guages attached on rack. There were variable restrictors in the lines to level out the pulses of the needles. Occasionally, I would hook each guage to the same vacuum port to ensure they were reading the same. Still have that set of guages, and bet they would still do the job.

I got kind of good at this job but got tired of the job because "here comes the badass auditor" wears on ya after a while. I am sure these days it wouldn't take long for me to drive them batshit once again.

Oh... you were THAT guy...

Damn right I was that guy!

And based on you starting this thread, you still are!!!

Blast from the past

Last time I had needle gauges taped to a rag on a bike was the 70's.
Also the first time I was pulled by the law on a bike, testing might have been a little spirited.
Got off with a warning.

So...Im guessing that the publicized QC issues at Mother Boeing would especially irk you.

Absolutely. The 737 door plug blowout was caused by a failure to follow written procedures. When I worked there following the procedures was adhered to.

Now I am jacking my own thread.

Ewwww! I hope you have a tissue!

I wasn't clear on who it was responsible for the door plug bolts loose.... wouldn't that be the maintenance crew's job if they had the door off and didn't put it back properly by the book? I'm assuming that plane wasn't brand new......

The plane was brand new and there is no maintenance required on door plug fasteners.

Here is how it played out.

The door plug is installed complete at the supplier and shipped to Boeing, meaning Boeing doesn't have to do (a f*ck thing) anything. Boeing Quality Assurance writes a discrepancy notice on the rivets in the door plug. The only way to fix the rivets is to remove the door plug. A removal record was not written per Boeing procedures so the responsibility and evidence of work complete was lost in the shuffle of shifts changes and time. The removal record would have included the steps to complete reassembly including installation of the the bolts and the progress of the work.
