Hello all!

I'm stumped on this one, I have an Stec30 w/ Altitude Hold that has been a bit buggy. We are 95% certain my pitch servo needs to be rebuilt. Rather than rebuild, I found a good/working pitch servo to install. The problem is the problem number is slightly different and nobody can seem to tell me why. I have a 1965 Mooney M20C - Pitch Servo is Stec Part #0107-P5. The good working one I found is Stec Part #0107-5-P5.         They look identical. Does anyone have a clue what that extra -5- is?     Thanks much!

Maxwell,

I can not help with the part number but you may try to resurrect your existing servo depending on your issue.   I have had three occasions where the pitch or roll servo (three different aircraft) was not acting normal or was erratic.  In all three cases I removed the cover and was able to use contact cleaner to flush the brush assembly and get everything working properly without disassembly.   Just a thought.
