Now THAT's a flow bench!

We paid a visit to Precision Airmotive in Arlington, WA today to check out their facility. Located on the southwest corner of the Arlington airport, Precision is where you go for Bendix fuel injection systems these days - it's a long story of acquisitions and divestitures that is hard to follow - but they are today's source for this design.

We looked at rows ad rows of servos, flow dividers, and injectors, either being torn down (for overhaul) or built up (from overhaul), or put together as new for customers all over the world.

Every servo is flow tested on this magnificent bench - the yellow "blimey" is a stand-in calibration tool for the bench. They have adapters and attachments for each of the different servos in their line. Next to this is a bench where they test and calibrate flow dividers, and next to that, a neat chamber where they spray fuel out of individual injectors and look at the spray pattern.

It's good to know that support for the Bendix systems is available and customers are well taken care of.
