I can't divulge more details about what we have created or give any hints. Lets just say that direct experience with these engines has taught us a lot and its time to capitalize on it while helping people avoid calling us with broken stuff.

Jake,
Do you keep track of the IMS bearings that you have replaced? With this information, do you know the amount of miles that have been placed on your bearings or the number of hours of track time they have been exposed to?

Also, how often do you suggest replacing the IMS bearing when using a LN bearing, to be on the safe side?

Thanks.

Yes, we keep EVERY SINGLE bearing.. We serialize each, log the owners name and mileage and other data about the engine. We have done this since day one.

The vibration sensor is something that I considered as well. As a Helicopter Crew Chief I used to test aircraft after work was done and the units of measurement was "IPS" or "iterations per second".. This would be one way of noting a trend in a M9 engine, however there are other things that can lead to vibration, not just the IMS.. Even a tank of bad gas can increase vibration.

Anything is better than nothing, but what we are doing is definitely going to give the most early warning possible.

Very cool Jake, can't wait to see what you come up with. Do you need any more bearings that are on the brink of destruction or do you have enough?
Let us know asap.

This is exciting stuff!

Jake, any timeline at all? One month, 2, 6?
