OS 160FX and pump question

[Bob Pastorello]

My pressure taps all were threaded 6-32 and I'm sure they went in at least two turns.  PLENTY using loctite.

  Thanks guys, sometimes I over-think stuff and make something simple into something complicated =)

  And BTW, I think removing the backplate for drilling anything back there should be like step #1 in the ole manual...I'm an A&P, so that was a no-brainer for me. But it also makes me want to over think stuff. Half of my problem.

  I'm going to have a look at the OS corner fitting there and see what's involved, and I may just do the backplate. BTW anybody know how thick that thing is? Are we talking 1 thread or 4?


  Thankye thankye,
  -Mike

    I just posted a picture of my pressure tap on my OS160FX.
    It is just a pressure tap from the hobby shop......4-40 tap size.....drill with appropriate tap drill size first. Tap the hole, clean up the burrs, a drop of Loctite, and snug it in.

      Ok, maybe I'm missing something obvious here. But, I have an OS 160 FX and a Perry V30 pressure type pump. Where in the heck do you tap this thing for pressure? There's usually a boss in the center of the back plate, or the back plate is smooth, or something. This engine has raised egdes that wouldn't allow for very easy drilling and tapping. 

      Any suggestions from those that have done this?

      thanks,
      -Mike
