Pmag internal temps.

Best cure would be to stop accepting devices unsuited for the prevalent temperatures.

Inspected my 114 P mags today and found right mag temp dot black. Left mag temp dot white. Both mags have had 1 inch scat blast tubes since original installation 2 years ago. The temps dots on both have always been white until todays inspection. This would have occurred sometime over the last 25 hours. No gear bearing play.

I'm wondering if a internal problem could be the culprit? All engine indications and the pre take off mag check are normal.

Has anybody seen this on their installation? Has anybody talked to tech support about this issue?

I have a call into our friends at Hartzell but the p mag guy is gone for the day. I'll post what he tells me when we make contact.

I posted on this in past.
- Talking with Hartzell I was told the 200 degree aspect is operational guidance, not a design limit.
- Here is my pMag temp strip at 700 hours. The temp strip shows the highest temp reached.

I gotta get the temp strips installed so I have better information. My main question is why after a couple of hot summers would I now have the over temp occur? Is it possible the mag has an internal malfunction causing the over temp since the other mag did not over temp according to the temp dot.

Can someone tell me a good source for this heat strip or similar brand.

Also how difficult is it to remove the strip and replace with a new one from time to time? Does the heat “weld” it to the mag base and make it a royal pain to remove?

Thanks.
